- Objective: The aim of this study was to analyse the concussion incidence rate ratios (IRR) across 29 seasons in a Swedish Hockey League team.Design: Cohort study over 29 seasons within one Swedish elite series ice hockey team. Participants: All players who were part of one Swedish elite ice hockey team during the research period gave consent for participation in the study.Independent Variables: Exposure to top level Swedish ice hockey. Main Outcome Measures: Incidence rate ratio for concussion as well as rehabilitation periods due to concussion were calculated and analysed.Results: During the research period, 267 players in total were part of the team. A total of 1638 traumatic injuries were registered of which 162 were concussions. Incidence rates ranged from 0/1,000 games during the first season to 118/1,000 games for the final recorded season. The incidence rate ratio was 1.06 (CI = 1.03-1.10) for the entire research period. A shift towards longer rehabilitation periods was discovered.Conclusions: This study showed a significant increase of concussion incidence rate and a trend towards longer rehabilitation periods due to concussion. Possible risk factors were discussed. Risk behaviour and rehabilitation protocols should be prioritized areas in the research of concussion in ice hockey.

High prevalence of former elite ice hockey players requiring early hip arthroplasty surgery
- 2024
-
Ingår i: Journal of Hip Preservation Surgery (JHPS). - : Oxford Univ Press. - 2054-8397.

Tidskriftsartikel (refereegranskat)abstract
- The high-impact nature of ice hockey puts the players at a higher risk of developing early hip osteoarthritis (OA). This study aims to evaluate the presence of cam morphology, early radiological findings of OA and total hip arthroplasty (THA) in former Swedish elite ice hockey players. Male elite ice hockey players in the highest league in Sweden seeking orthopedic consultation for hip and groin pain with restricted hip joint range of motion and subsequent radiographs (Antero/posterior view, Lauenstein view and/or Hip frontal view) were included. The radiographs were performed between 1988 and 2009 and retrospectively examined for the presence of cam morphology (evaluated by alpha-angle >= 60 degrees) and hip OA (evaluated by Tonnis classification). All players were contacted between 11 and 33 years after baseline radiograph examination for follow-up investigation of the presence of subsequent THA. A total of 44 male ice hockey players were included, of which 31 had available radiographs and 39 answered the follow-up questions. Cam morphology (alpha-angle >= 60 degrees) was present in 81% of the players. Seven players (18%) had received a THA with a mean age of 55.7 (SD 6.1) years at time of THA-surgery. Tonnis score at baseline radiographs were associated with THA later in life (P < 0.001). This study conclude that former elite Swedish ice hockey players underwent THA at a younger age than the general population. Despite confirming previous research of high prevalence of cam morphology in elite ice hockey players, no association could be established between cam morphology and the need for THA.

Union of Scaphoid Waist Fractures in Adults Despite No or Minimal Immobilization : a Report of Five Cases
- 2020
-
Ingår i: SN Comprehensive Clinical Medicine. - : Springer. - 2523-8973. ; 2:4, s. 491-495
-
Tidskriftsartikel (refereegranskat)abstract
- Traditionally scaphoid waist fractures have been treated with a long period, 10–12 weeks, of immobilization in a plaster cast until radiological union. The long period of immobilization sometimes infers great discomfort for the patients. To avoid this, surgical treatment with screw fixation has for the last decade been advocated as an option also for undisplaced fractures. In this report, we present five cases with undisplaced scaphoid waist fractures that have healed both radiologically and clinically without any immobilization at all or after a very short period of protection in a cast. These observations challenge the current treatment guidelines.

Long-term postural control in elite athletes following mild traumatic brain injury
- 2022
-
Ingår i: Frontiers in Neurology. - : Frontiers Media S.A.. - 1664-2295. ; 13
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Traumas to the head and neck are common in sports and often affects otherwise healthy young individuals. Sports-related concussions (SRC), defined as a mild traumatic brain injury (mTBI), may inflict persistent neck and shoulder pain, and headache, but also more complex symptoms, such as imbalance, dizziness, and visual disturbances. These more complex symptoms are difficult to identify with standard health care diagnostic procedures.Objective: To investigate postural control in a group of former elite athletes with persistent post-concussive symptoms (PPCS) at least 6 months after the incident.Method: Postural control was examined using posturography during quiet stance and randomized balance perturbations with eyes open and eyes closed. Randomized balance perturbations were used to examine motor learning through sensorimotor adaptation. Force platform recordings were converted to reflect the energy used to maintain balance and spectrally categorized into total energy used, energy used for smooth corrective changes of posture (i.e., <0.1 Hz), and energy used for fast corrective movements to maintain balance (i.e., >0.1 Hz).Results: The mTBI group included 20 (13 males, mean age 26.6 years) elite athletes with PPCS and the control group included 12 athletes (9 males, mean age 26.4 years) with no history of SRC. The mTBI group used significantly more energy during balance perturbations than controls: +143% total energy, p = 0.004; +122% low frequency energy, p = 0.007; and +162% high frequency energy, p = 0.004. The mTBI subjects also adapted less to the balance perturbations than controls in total (18% mTBI vs. 37% controls, p = 0.042), low frequency (24% mTBI vs. 42% controls, p = 0.046), and high frequency (6% mTBI vs. 28% controls, p = 0.040). The mTBI subjects used significantly more energy during quiet stance than controls: +128% total energy, p = 0.034; +136% low-frequency energy, p = 0.048; and +109% high-frequency energy, p = 0.015.Conclusion: Athletes with previous mTBI and PPCS used more energy to stand compared to controls during balance perturbations and quiet stance and had diminished sensorimotor adaptation. Sports-related concussions are able to affect postural control and motor learning.

Shorter Recovery Time in Concussed Elite Ice Hockey Players by Early Head-and-Neck Cooling: A Clinical Trial
- 2023
-
Ingår i: Journal of Neurotrauma. - : Mary Ann Liebert. - 0897-7151 .- 1557-9042. ; 40:11-12, s. 1075-1085
-
Tidskriftsartikel (refereegranskat)abstract
- A sports-related concussion (SRC) is most commonly sustained in contact sports, and is defined as a mild traumatic brain injury. An exercise-induced elevation of core body temperature is associated with increased brain temperature that may accelerate secondary injury processes following SRC, and exacerbate the brain injury. In a recent pilot study, acute head-neck cooling of 29 concussed ice hockey players resulted in shorter time to return-to-play. Here, we extended the clinical trial to include players of 19 male elite Swedish ice hockey teams over five seasons (2016-2021). In the intervention teams, acute head-neck cooling was implemented using a head cap for ≥45 min in addition to the standard SRC management used in controls. The primary endpoint was time from SRC until return-to-play (RTP). Sixty-one SRCs were included in the intervention group and 71 SRCs in the control group. The number of previous SRCs was 2 (median and interquartile range [IQR]: 1.0-2.0) and 1 (IQR 1.0-2.0) in the intervention and control groups, respectively; p = 0.293. Median time to initiate head-neck cooling was 10 min (IQR 7-15; range 5-30 min) and median duration of cooling was 45 min (IQR 45-50; range 45-70 min). The median time to RTP was 9 days in the intervention group (IQR 7.0-13.5 days) and 13 days in the control group (IQR 9-30; p < 0.001). The proportion of players out from play for more than the expected recovery time of 14 days was 24.7% in the intervention group, and 43.7% in controls (p < 0.05). Study limitations include that: 1) allocation to cooling or control management was at the discretion of the medical staff of each team, decided prior to each season, and not by strict randomization; 2) no sham cap was used and evaluations could not be performed by blinded assessors; and 3) it could not be established with certainty that injury severity was similar between groups. While the results should thus be interpreted with caution, early head-neck cooling, with the aim of attenuating cerebral hyperthermia, may reduce post-SRC symptoms and lead to earlier return-to-play in elite ice hockey players.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundThis study aims at assessing the validity and reliability of the Spanish version of the Lysholm score, a widely used instrument for assessing knee function and activity level after ligament injuries.MethodsNinety-five participants (67.4% male, 22±5 years) completed the questionnaire twice within 7 days and a subsample of 42 participants completed a test-retest reliability. Reliability, validity and feasibility psychometric properties were studied. The validity of the questionnaire was analysed using ceiling and floor effects. Factor structure and construct validity were analysed with the SF-36, the Hip and Knee Questionnaire (HKQ) and one leg jump test (OLJT).ResultsCriterion validity with the SF-36 Physical State was moderate (r = 0.50 and p<0.01), poor and inverse relationship (r = -0.31, p<0.01) with HKQ and positive moderate (r = 0.59, p<0.01) with OLJT. Measurement error from MDC90 was 3.9%. Exploratory factor analysis demonstrated a one-factor solution explaining 51.5% of total variance. The x2 test for the one-factor model was significant (x2 = 29.58, df = 20, p < 0.08). Test-retest reliability level was high (ICC2.1 = 0.92, p<0.01) and also the internal consistency (α = 0.77).ConclusionThe Spanish Lysholm score demonstrated that it is a reliable and valid instrument that can be used to assess knee function after ligament injuries.

- Background and Purpose: Despite a decreasing tendency of head and facial injuries in ice hockey the number of these injuries still seems to be too high. The purpose of this prospective investigation was to study the mechanism of facial and eye injuries as well as the role of protective equipment and revised rules. Methods: A prospective epidemiologic analysis of ice hockey-related injuries in the two highest-ranking Swiss Ice Hockey Leagues-League A (NLA) and B (NLB)-was performed by the Swiss Medical Committee during the two seasons 1996 and 1997. Results: A total of 392 injuries occurred during games or practice. Head injuries and facial injuries made up 26% of these injuries. Most of these injuries were classified as minor injuries. All eye injuries occurred in players either not wearing visors at all or wearing the visor incorrectly. Most injuries were caused by the illegal use of sticks. Conclusion: Most head injuries and facial injuries could be prevented by wearing helmet and visor correctly and by playing the game according to the rules

Forskningsöversikt (refereegranskat)abstract
- The number of minor traumatic brain injury (mTBI), cerebral concussions, is increasing and cannot be eliminated by any kind of equipment. Prevention strategies, such as the introduction of "checking from behind" rules have become effective in decreasing the number of severe spinal injuries. A new "head checking" rule should reduce mTBI in the same way in the following years. Mouthguards should be mandatory as an effective device for the prevention of dental and orofacial injuries, as well as reducing the incidence and severity of mTBI. A new internet database system, the International Sports Injury System (ISIS) should improve epidemiological analysis of head, face, and spinal injuries worldwide.ISIS should provide an internationally compatible system for continuous monitoring of risk factors, protective effects of equipment, and protective effects of equipment and effects of changes in rules through the years.

Tidskriftsartikel (refereegranskat)abstract
- Background: In 1982, the Lysholm score was first published as a physician-administered score in the American Journal of Sports Medicine. The Tegner activity scale was published in 1985.Hypothesis: The Lysholm and Tegner scores are valid as patient-administered scores and responsive at early time points after treatment of anterior cruciate ligament tears.Study Design: Cohort study (Diagnosis); Level of evidence, 1. Methods: All patients were treated for an anterior cruciate ligament tear. For responsiveness, the Lysholm score (n = 1075) and Tegner activity level (n = 505) were measured preoperatively and 6, 9, 12, and 24 months postoperatively. For test-retest (n = 50), scores were measured at 2 years postoperatively and again within 4 weeks by questionnaire. For criterion validity (n = 170), patients completed the Short Form-12 and the International Knee Documentation Committee score in addition to Lysholm and Tegner instruments. For all other analyses, preoperative Lysholm score (n = 1783) or Tegner activity levels (n = 687) were collected.Results: There was acceptable test-retest reliability for both the Lysholm (intraclass correlation coefficient = 0.9) and Tegner (intraclass correlation coefficient = 0.8) scores. The minimum detectable change for Lysholm was 8.9 and for Tegner was 1. The Lysholm demonstrated acceptable internal consistency. The Lysholm correlated with the International Knee Documentation Committee (r = .8) and the Short Form-12 (r = .4), and Tegner correlated with the Short Form-12 (r = .2). Both scores had acceptable floor and ceiling effects and all hypotheses were significant. The Lysholm and Tegner were responsive to change at each of the time points.Conclusion: After 25 years of changes in treatment of anterior cruciate ligament injuries, the Lysholm knee score and the Tegner activity scale demonstrated acceptable psychometric parameters as patient-administered scores and showed acceptable responsiveness to be used in early return to function after anterior cruciate ligament treatment.

Tidskriftsartikel (refereegranskat)abstract
- Background: Ice hockey and football players suffering concussions might have an increased risk for injuries afterwards. We aimed to investigate if concussions predisposed athletes for subsequent sport injuries.Methods: Patient data were obtained from a data base established at the University Hospital in Umea, Sweden. Athletes who had suffered a concussion were included if they had been aged between 15 and 35 years of age, and played ice hockey, football (soccer), floorball and handball. They were studied in terms of all new or previous injuries during 24 months before and after their concussion. Results were compared with a control group of athletes from the same four sports with an ankle injury.Results: Athletes with a concussion were more likely to sustain injuries compared with the control group, both before (OR 1.98. 95% CI 1.45 to 2.72) and after the concussion (OR 1.72. 95% CI 1.26 to 2.37). No increase in frequency of injury was found after a concussion compared with before. This was true for athletes in all four sports and for both sexes.Conclusions: This study indicates that athletes sustaining a concussion may have a more aggressive or risk-taking style of play than their counterparts. Our data do not suggest that a concussion injury, per se, leads to subsequent injuries.

Analys av kollisioner vid hockeyspel med hjärnskakning som utfall
- 2020
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Detta projekt får anses utgöra en pilotstudie som visar på både möjligheter och svårigheter med att analysera hjärnskakningar hos hockeyspelare utifrån tillgängliga videofilmer, RTP och blodprovsdata. Att konstruera en modell som ger mer detaljerad information om orsaken till hjärnskakning och dess omfattning bedöms som möjlig men svårt. Med tillgång till fler kameravinklar och deras exakta positioner i förhållande till isen kan en bildanalys utföras mycket mer exakt. Man bör också ta i beaktning de relativt få spelare som analyserades. Data från fler spelare bedöms som en framkomlig väg även ifall insamlingsmetoderna och analysen förblir den samma som i den här studien. Ytterligare data skulle sannolikt medföra att analysen av korrelationer med RTP och HUC gav tydligare svar. Även om inte de planerade numeriska modellerna av spelarna gick att förverkliga gav kinematikanalysen användbara resultat; bland annat kollisionshastigheten. Försök att korrelera kollisionshastigheten med RTP gjordes men någon korrelation förelåg inte. Andra faktorer; som hur våldsam rotationen av huvudet var vid kollisionen har känd större inverkan på risken för hjärnskakning än ingångshastigheten. Noterbart är att de erhållna kollisionshastigheterna beror på manuell utplacering av referenspunkter som lagt grunden för koordinatsystemet. Utifrån detta koordinatsystem har sedan hastigheterna erhållits; små fel vid skapandet av koordinatsystemet påverka kollisionshastigheterna stort. Den utförda analysen är baserad på HUC. Den har utförts något annorlunda än på det sett som utvecklarna av HUC avsåg. Fyra bedömare har utfört analysen och det blev uppenbart att några faktorer var svårbedömda. Inför framtida studier där film från kollisioner karakteriseras med hjälp där HUC bör några av beskrivningarna av faktorerna kompletteras. Resultaten i korthet: I stort sätt alla analyserade kollisionerna uppstår i kontakt mellan två spelare. De vanligaste kontakterna var mellan huvud och opponentens axelskydd och mellan huvud och armbåge; 58% respektive 21% av de analyserade kollisionerna. Den drabbade träffades i 66% av kollisionerna i huvudet och 25% i överkroppen. Vanligast var träffar framifrån. Den resulterande huvudrörelsen var oftast komplex alternativt begränsad till sagittalplanet. Efter den första träffen följde det minst en andra huvudträff i 44% av kollisionerna. Hälften av dessa andra träffar var med isen och andra hälften med ringsargen. Kollisionerna skedde i alla zoner och på öppen is samt i närheten av sargen. Lika många av spelarna bedömdes varit medvetna om att en tackling väntade som de som var omedvetna. Straff utdelades som en följd i 34% av kollisionerna; trots att 75% av tacklingarna bedömdes planerade. Kollisionshastigheten varierade mellan 5,0 m/s och 11,6 m/s. RTP är inte en funktion av ålder, riktningen på huvudaccelerationen eller kollisionshastigheten. Resultaten indikerar att RTP var högre när den drabbade blev träffad av en axel relativt av en armbåge. RTP var högre för de spelare som bedömdes omedveten om den förstående tacklingen. RTP var mycket högre för planerade tacklingar i jämförelse med tacklagar som var en följd i en situation där tacklingen är en del i en oplanerad kollision. För varaktiga symptom, d.v.s. för de fyra spelare som inte återgick till spel på elitnivå efter kollisionen, var 75% träffade av motståndarens axel och lika stor andel träffade i huvudet. I alla fyra fallen ansågs den drabbade ej ha kunnat förutse tacklingen samt opponenten bedömdes ha planerat tacklingen. Medelkoncentrationen av blodmarkören NFL sjunker vid mätningarna vid 12 h och vid 36 h relativt 1 h men ökar något vid 144 h relativt 1 h. Medelvärdet av parade NFL-koncentrationerna förblir i stort sätt oförändrade över tiden förutom vid 144 h då det förekommer en icke statistiskt signifikant ökning. Det går att skönja en svag korrelation mellan RTP och förändringen av NFL vid 12 h, 36 h och 144 h i relation till värdena vid 1 h; högre RTP för högre NFL NFL-värden för gruppen RTP ≥ 9 dagar skiljer sig inte signifikant mot värden för gruppen RTP < 9 dagar vid 12h, 26 h eller vid 144 h efter kollisionen. NFL-värdena kan prediktera RTP men resultaten är inte signifikanta. Parade koncentrationer av blodmarkörerna NSE, S100B och tau sjunker signifikant vid 12 h i relation till nivåerna vid 1h efter trauma. Dessa förändringar var inte förväntade. Koncentrationsändringarna av NSE, S100B och tau för gruppen RTP ≥ 9 dagar skiljer sig inte signifikant mot värden för gruppen RTP < 9 dagar vid 12h, 26 h eller vid 144 h efter kollisionen.

Tidskriftsartikel (refereegranskat)abstract
- Aim: To describe what suffering multiple concussions meant for former semi-professional or professional hockey players who were forced to end their career. Results: Nine former Swedish hockey players, who once played on national or professional teams were interviewed. The interviews were analyzed with reference to hermeneutic phenomenology to interpret and explain their experiences. The theme of losing one’s identity as a hockey player was constructed from five subthemes: being limited in everyday life, returning to the hockey stadium as soon as possible, forming a post career identity, lacking understanding and support, and preventing injuries by respecting other players. Conclusion: The former hockey players struggled with developing their off-the-ice identities and with finding other sources of meaning for their lives.Lay abstractDespite considerable attention to improving the initial management of concussions suffered by hockey players, few studies have examined their long-term effects. In response, the study reported here aimed to describe what suffering multiple concussions meant for former semi-professional or professional hockey players who were forced to end their career. Nine former Swedish hockey players, who once played on national or professional teams were interviewed and the interviews were analyzed in order to interpret and explain their experiences. The overall theme was formulated as losing one’s identity as a hockey player. In conclusion, the former hockey players seem to struggle with developing their off-the-ice identities and with finding other sources of meaning for their lives.

Tidskriftsartikel (refereegranskat)abstract
- Background: Professional ice hockey players may contract irritant and allergic contact dermatitis.Aims: To investigate the presence of contact allergy (CA) in professional ice hockey players in Sweden.Methods: Ten teams from the two top leagues were assessed for potential occupational exposure to sensitizers. Exactly 107 players were patch tested with an extended baseline series and a working series, in total 74 test preparations. The CA rates were compared between the ice hockey players and controls from the general population and dermatitis patients.Results: One out of 4 players had at least one contact allergy. The most common sensitizers were Amerchol L 101, nickel and oxidized limonene. CA was as common in the ice hockey players as in dermatitis patients and significantly more common than in the general population. Fragrances and combined sensitizers in cosmetic products (fragrances + preservatives + emulsifier) were significantly more common in ice hockey players compared with the general population.Conclusion: The possible relationship between CA to fragrances and cosmetic products on the one hand and the presence of dermatitis on the other should be explored further.

- survey was undertaken in all ice hockey players in 26 professional teams in Sweden representing the two highest divisions. All players answered a questionnaire and the players from six teams, three from each of the two divisions, were patch tested with 72 test preparations in a baseline series supplemented with a series representing the work environment of the players. For practical reasons, the patch testing and test reading on day 3 took place in the arenas of the teams. As a traditional dermatologist reading on day 7 was impossible to perform in all but one team, the players and coaches were asked to use their mobile phones to take photos of the tested backs of the players on day 7 and to send them to the investigative team. In one team a dermatologist reading took place on day 7 independently of the mobile phone photos. In total, 107 players in the six teams were patch tested, and a reading on day 3 was performed in 103. Fifty contact allergic reactions were noted in 26 players. When comparing the reactions present on day 3 with the photos from day 7, seven (14%) more positive reactions were registered. The seven additional reactions were noted to seven different sensitizers: hexavalent chromium, oxidized linalool, thiomersal, mercapto mix, mercaptobenzothiazole, PFR-2 (a resol resin based on phenol and formaldehyde) and methylenedianiline. In summary, 14% more contact allergic reactions were diagnosed when using photos of the tested backs to replace the traditional dermatologist reading.

- Study Design Clinical measurement. Background The Lysholm score and Tegner Activity Scale are frequently used patient-reported instruments to determine the functional status and activity level after anterior cruciate ligament (ACL) reconstruction. Objectives To translate and cross-culturally adapt the Lysholm score and Tegner Activity Scale for use in the Dutch population and to evaluate reliability and validity of these questionnaires in individuals after ACL reconstruction. Methods The translation and adaptation was conducted in several steps according to the guidelines in the literature. The measurement properties of the Lysholm score and Tegner Activity Scale (internal consistency, construct validity, and floor and ceiling effects) were tested in 96 patients. Reproducibility was tested in 69 patients, for patient with anterior cruciate ligament injuries. On the first occasion, the International Knee Documentation Committee (IKDC) and RAND-36 item Health Survey (RAND-36) were also administered. Results The Lysholm score and Tegner Activity Scale showed good test-retest reliability between repeated measures (respectively ICC 0.93 and 0.97). Internal consistency was reasonable to good (Cronbach's α=0.70-0.83). The Lysholm score had a very strong correlation with the IKDC (r= 0.83, p<0.01) and moderate correlation with the RAND-36 (r=0.55, p<0.01). The Tegner Activity Scale had a moderate correlation with both IKDC and the RAND-36 (r= 0.42 p<0.01 respectively r= 0.48 p<0.01). Conclusion This study demonstrated acceptable psychometric performances for the Lysholm score and the Tegner scale as outcome measures for Dutch patients after ACL reconstruction.

- Between 1973 and 1981, 101 patients had a Putti-Platt repair for recurrent dislocation of the shoulder; 89 of them were followed up and 43 underwent a clinical examination, 23 being assessed with the Cybex dynamometer. The 46 who did not attend were interviewed by telephone. The mean follow up time was 8 +/- 2 years (range 5-14 years). Redislocation occurred in 18 patients (20%), but this was twice as high in patients who were aged under 26 years at the time of operation compared with those who were older (29% versus 13%). The time of recurrence was between 1 and 11 years after operation. A decrease in strength and power of abduction, internal and external rotation, was found in the affected shoulder. Restriction of all measured movements, particularly external rotation, was also found in all patients. Nevertheless most had a high functional score and relatively few symptoms. We conclude that the Putti-Platt procedure has a high recurrence rate in younger patients, and we hesitate to recommend it for young active individuals.

Cerebrospinal fluid levels of neuroinflammatory biomarkers are increased in athletes with persistent post-concussive symptoms following sports-related concussion
- 2023
-
Ingår i: Journal of Neuroinflammation. - : Springer Nature. - 1742-2094. ; 20
-
Tidskriftsartikel (refereegranskat)abstract
- A sports-related concussion (SRC) is often caused by rapid head rotation at impact, leading to shearing and stretching of axons in the white matter and initiation of secondary inflammatory processes that may exacerbate the initial injury. We hypothesized that athletes with persistent post-concussive symptoms (PPCS) display signs of ongoing neuroinflammation, as reflected by altered profiles of cerebrospinal fluid (CSF) biomarkers, in turn relating to symptom severity. We recruited athletes with PPCS preventing sports participation as well as limiting work, school and/or social activities for ≥ 6 months for symptom rating using the Sport Concussion Assessment Tool, version 5 (SCAT-5) and for cognitive assessment using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Following a spinal tap, we analysed 27 CSF inflammatory biomarkers (pro-inflammatory chemokines and cytokine panels) by a multiplex immunoassay using antibodies as electrochemiluminescent labels to quantify concentrations in PPCS athletes, and in healthy age- and sex-matched controls exercising ≤ 2 times/week at low-to-moderate intensity. Thirty-six subjects were included, 24 athletes with PPCS and 12 controls. The SRC athletes had sustained a median of five concussions, the most recent at a median of 17 months prior to the investigation. CSF cytokines and chemokines levels were significantly increased in eight (IL-2, TNF-α, IL-15, TNF-β, VEGF, Eotaxin, IP-10, and TARC), significantly decreased in one (Eotaxin-3), and unaltered in 16 in SRC athletes when compared to controls, and two were un-detectable. The SRC athletes reported many and severe post-concussive symptoms on SCAT5, and 10 out of 24 athletes performed in the impaired range (Z < − 1.5) on cognitive testing. Individual biomarker concentrations did not strongly correlate with symptom rating or cognitive function. Limitations include evaluation at a single post-injury time point in relatively small cohorts, and no control group of concussed athletes without persisting symptoms was included. Based on CSF inflammatory marker profiling we find signs of ongoing neuroinflammation persisting months to years after the last SRC in athletes with persistent post-concussive symptoms. Since an ongoing inflammatory response may exacerbate the brain injury these results encourage studies of treatments targeting the post-injury inflammatory response in sports-related concussion.

Post-Concussive Vestibular Dysfunction Is Related to Injury to the Inferior Vestibular Nerve
- 2022
-
Ingår i: Journal of Neurotrauma. - : Mary Ann Liebert Inc. - 0897-7151 .- 1557-9042. ; 39:11-12
-
Tidskriftsartikel (refereegranskat)abstract
- Symptoms of vestibular dysfunction such as dizziness and vertigo are common after sports-related concussions (SRC) and associated with a worse outcome and a prolonged recovery. Vestibular dysfunction after SRC can be because of an impairment of the peripheral or central neural parts of the vestibular system. The aim of the present study was to establish the cause of vestibular impairment in athletes with SRC who have persisting post-concussive symptoms (PPCS). We recruited 42 participants-21 athletes with previous SRCs and PPCS >= 6 months and 21 healthy athletic age- and sex-matched controls-who underwent symptom rating, a detailed test battery of vestibular function and 7T magnetic resonance imaging with diffusion tensor imaging (DTI) and diffusion kurtosis imaging (DKI) of cerebellar white matter tracts, and T1-weighted imaging for cerebellar volumetrics. Vestibular dysfunction was observed in 13 SRC athletes and three controls (p = 0.001). Athletes with vestibular dysfunction reported more pronounced symptoms on the Dizziness Handicap Inventory (DHI; p < 0.001) and the Hospital Anxiety and Depression Scale (HADS; p < 0.001). No significant differences in DTI metrics were found, while in DKI two metrics were observed in the superior and/or inferior cerebellar tracts. Cerebellar gray and white matter volumes were similar in athletes with SRC and controls. Compared with controls, pathological video head impulse test results (vHIT; p < 0.001) and cervical vestibular evoked myogenic potentials (cVEMP; p = 0.002) were observed in athletes with SRC, indicating peripheral vestibular dysfunction and specifically suggesting injury to the inferior vestibular nerve. In athletes with persisting symptoms after SRC, vestibular dysfunction is associated with injury to the inferior vestibular nerve.

Tidskriftsartikel (refereegranskat)abstract
- Background: Sports-related concussion (SRC) is increasingly recognized as a potential health problem in ice hockey. Quality of life (QoL) in players retiring due to SRC has not been thoroughly addressed. Materials & methods: QoL using the Sports Concussion Assessment Tool 5th Edition, Impact of Event Scale-Revised and Short Form Health Survey was measured in Swedish ice hockey players who retired due to persistence of postconcussion symptoms or fear of attaining additional SRC. Results: A total of 76 players were assessed, on average of 5 years after their most recent SRC. Overall, retired players had a high burden of postconcussion symptoms and reduced QoL. Conclusion: Retired concussed ice hockey players have a reduced QoL, particularly those retiring due to postconcussion symptoms. Symptom burden should be continuously evaluated and guide the decision to retire.

Selective head–neck cooling after concussion shortens return-to-play in ice hockey players
- 2021
-
Ingår i: Concussion. - : Future Medicine Ltd. - 2056-3299. ; 6:2
-
Tidskriftsartikel (refereegranskat)abstract
- We aimed to investigate whether selective head–neck cooling could shorten recovery after sports-related concussions (SRCs). In a nonrandomized study of 15 Swedish professional ice hockey teams, 29 concussed players received immediate head and neck cooling for ≥30 min (initiated at 12.3 ± 9.2 min post-SRC by a portable cooling system), and 52 SRC controls received standard management. Players receiving head–neck cooling had shorter time to return-to-play than controls (7 vs 12.5 days, p < 0.0001), and 7% in the intervention group versus 25% in the control group were out of play for ≥3 weeks (p = 0.07). Immediate selective head–neck cooling is a promising option in the acute management of SRC that should be addressed in larger cohorts.

Widespread White Matter Abnormalities in Concussed Athletes Detected by 7T Diffusion Magnetic Resonance Imaging
- 2024
-
Ingår i: Journal of Neurotrauma. - : Mary Ann Liebert. - 0897-7151 .- 1557-9042. ; 41:13-14, s. 1533-1549

Tidskriftsartikel (refereegranskat)abstract
- Sports-related concussions may cause white matter injuries and persistent post-concussive symptoms (PPCS). We hypothesized that athletes with PPCS would have neurocognitive impairments and white matter abnormalities that could be revealed by advanced neuroimaging using ultra-high field strength diffusion tensor (DTI) and diffusion kurtosis (DKI) imaging metrics and cerebrospinal fluid (CSF) biomarkers. A cohort of athletes with PPCS severity limiting the ability to work/study and participate in sport school and/or social activities for ≥6 months completed 7T magnetic resonance imaging (MRI) (morphological T1-weighed volumetry, DTI and DKI), extensive neuropsychological testing, symptom rating, and CSF biomarker sampling. Twenty-two athletes with PPCS and 22 controls were included. Concussed athletes performed below norms and significantly lower than controls on all but one of the psychometric neuropsychology tests. Supratentorial white and gray matter, as well as hippocampal volumes did not differ between concussed athletes and controls. However, of the 72 examined white matter tracts, 16% of DTI and 35% of DKI metrics (in total 28%) were significantly different between concussed athletes and controls. DKI fractional anisotropy and axial kurtosis were increased, and DKI radial diffusivity and radial kurtosis decreased in concussed athletes when compared with controls. CSF neurofilament light (NfL; an axonal injury marker), although not glial fibrillary acidic protein, correlated with several diffusion metrics. In this first 7T DTI and DKI study investigating PPCS, widespread microstructural alterations were observed in the white matter, correlating with CSF markers of axonal injury. More white matter changes were observed using DKI than using DTI. These white matter alterations may indicate persistent pathophysiological processes following concussion in sport.

Function testing in patients with old rupture of the anterior cruciate ligament
- 1990
-
Ingår i: International Journal of Sports Medicine. - : Georg Thieme Verlag KG. - 0172-4622 .- 1439-3964. ; 11:1, s. 73-77

Tidskriftsartikel (refereegranskat)abstract
- Fifteen patients with isolated old rupture of the anterior cruciate ligament (ACL) were examined to judge their functional disability. The following basic factors were used for evaluation: thigh muscle strength testing, stabilometry in a one-leg stance with straight and flexed knee, gait analysis, performance tests, knee function score, activity grading scale, and clinical joint laxity tests. We found that these rehabilitated patients mainly had impaired performance in those tests which greatly stressed the knee joint's sagittal stability. One-leg hop length was impaired for the injured limb. This group of patients had bilateral impairment of postural control compared with a reference group. This dysfunction was not revealed when comparing limbs. A derotation brace (ECKO) had neither a positive nor a negative effect in the tests. Different aspects of knee function evaluation are emphasized. Some of the altered functions are suggested to be due to central adjustments of motor control.

Reliability and Validity of a Chinese Version of the Lysholm Score and Tegner Activity Scale for Knee Arthroplasty
- 2022
-
Ingår i: Journal of Rehabilitation Medicine. - : Medical Journals Sweden. - 1650-1977 .- 1651-2081. ; 54
-
Tidskriftsartikel (refereegranskat)abstract
- Objective: To verify the reliability and validity of Chinese versions of the Lysholm score and the Tegner activity scale for knee arthroplasty.Methods: Sixty-four patients undergoing total knee arthroplasty and 28 healthy volunteers were included in this study. Participants were divided into 4 groups: a pre-operation group; a 3 months post-operation group; a 1-year post-operation group; and a control group of healthy volunteers. Participants completed the Lysholm score and Tegner activity scale twice over a period of 3–7 days.Results: The intraclass correlation coefficients of the Lysholm score and Tegner scale were both relatively high, at 0.99 and 0.97, respectively. Moreover, the Cronbach’s alpha of the Lysholm score was 0.71. The items “locking” and “instability” differed slightly between groups (Kruskal–Wallis: for locking, χ2 (p) = 13.48, p = 0.0037; for instability, χ2 (p) = 4.32, p = 0.2292).Conclusion: The simplified-Chinese versions of the Lysholm score and the Tegner scale are applicable for use with patients undergoing total knee arthroplasty, and have relatively high validity and reliability. The items “locking” and “instability” should be combined with clinical data to make the Lysholm score more suitable for assessment of total knee arthroplasty.

Soccer-Related Concussions Among Swedish Elite Soccer Players : A Descriptive Study of 1,030 Players
- 2020
-
Ingår i: Frontiers in Neurology. - : Frontiers Media S.A.. - 1664-2295. ; 11
-
Tidskriftsartikel (refereegranskat)abstract
- Objective:There are growing concerns about the short- and long-term consequences of sports-related concussion, which account for about 5-9% of all sports injuries. We hypothesized there may be sex differences in concussion history and concussion-related symptoms, evaluated among elite soccer players in Sweden. Design:Retrospective survey study. Participants and Setting:Soccer players (n= 1,030) from 55 Swedish elite soccer teams. Questionnaires were completed prior to the start of the 2017 season. Assessment of Risk Factors:Player history of soccer-related concussion (SoRC), symptoms and management following a SoRC were evaluated. Main Outcome Measures:Before the start of the season the players completed a baseline questionnaire assessing previous concussions. The Sports Concussion Assessment Tool 3 was included with regard to symptom evaluation. Results:Out of 993 responding players 334 (34.6%) reported a previous SoRC and 103 players (10.4%) reported a SoRC during the past year. After sustaining a SoRC, 114 players (34.2%) reported that they continued their ongoing activity without a period of rest, more commonly female (44.9%) than male players (27.7%;P= 0.002). Symptom resolution time was 1 week or less for 61.3% of the players that reported having persisting symptoms. A positive correlation was observed between number of previous concussions and prevalence of three persisting symptoms: fatigue (P< 0.001), concentration/memory issues (P= 0.002) and headache (P= 0.047). Conclusion:About 35% of male and female elite soccer players in Sweden have experienced a previous SoRC, and about 10% experienced a SoRC during the last year. Female players continued to play after a SoRC, without a period of rest, more often than males. A higher risk of persisting symptoms was observed in players with a history of multiple concussions.

Validity and Reliability of the Thai Versions of the Lysholm Knee Scoring Scale and Tegner Activity Scale
- 2023
-
Ingår i: The Orthopaedic Journal of Sports Medicine. - : Sage Publications. - 2325-9671. ; 11:2
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Functional or quality of life questionnaires are important tools in clinical investigations. The Lysholm Knee Scoring Scale and Tegner Activity Scale are knee-specific questionnaires that are widely used to assess knee function.Purpose: To translate both questionnaires into Thai and to assess the validity and reliability of the Thai versions of the Lysholm and adjusted Tegner scales.Study Design: Cohort study (diagnosis); Level of evidence, 3.Methods: The Lysholm and Tegner scales were translated into Thai by using the forward-backward translation protocol. Because cultural modifications were made to the sports used to measure activity on the Tegner scale, the authors of this study refer to the Thai version as the “Thai adjusted Tegner scale.” The reliability and validity of the translated scales were evaluated by obtaining the responses of 60 consecutive patients (mean age, 40.5 years; 34 male, 26 female); the patients also completed the Thai version of the International Knee Documentation Committee Subjective Knee Form (IKDC-SKF). Criterion validity was tested by correlating the scores from both translated questionnaires with those from the Thai IKDC-SKF, while reliability was assessed by measuring test-retest reliability and internal consistency.Results: The Thai Lysholm scale showed a strong correlation with the Thai IKDC-SKF (r = 0.89), while the Thai adjusted Tegner scale showed a moderate correlation with the Thai IKDC-SKF (r = 0.60). The intrarater and test-retest reliability measures were excellent for the Thai Lysholm (intraclass correlation coefficient [ICC], 0.94 and 0.98, respectively) and moderate to good for the Thai adjusted Tegner (ICC, 0.73 and 0.86, respectively). The internal consistency for the Thai Lysholm was acceptable at all the time points (Cronbach alpha, 0.71-0.73).Conclusion: The Thai Lysholm and Thai adjusted Tegner scales adequately retained the characteristics of the original versions. They can be considered reliable instruments for Thai patients with knee-related problems.

Tidskriftsartikel (refereegranskat)abstract
- In this 1-year prospective study, the aim was to investigate if there are any differences concerning injuries and injury incidence during an entire football season between Swedish female football players from different geographical regions. A total of 130 out of 253 players (51%) sustained 229 injuries. The overall injury incidence was 9.6/1000 h of football. The incidence of injury during practice was 8.4/1000 h and during game was 13.3/1000 h. Players in the north had a higher incidence of injury during game than those in the south (19.5 vs. 7.2/1000 h, respectively, p<0.001). Fifty-nine per cent of all injuries were traumatic injuries. Both traumatic and overuse injuries occurred mainly during the early preseason and at the beginning of the competitive spring season. Of all injuries, 13% were classified as slight, 39% as minor, 37% as moderate and 11% as major injuries. Players in the north had a higher injury incidence concerning moderate injuries than players in the south (p<0.01). In the present study, evidence is presented that regional factors play a role in the injury incidence. Female football players in the north and south have different injury patterns. This could be a result of different conditions for football as a sport between the regions.

- Injury occurrence in all 12 female elite senior football teams in premiere league was registered during 1 year. Of 269 players, 129 (48%) sustained 237 injuries. The total injury incidence was 4.6/1000 h of football. The injury incidence during practice was 2.7 and during the game time was 13.9/1000 h. The highest injury incidence during practice was to the knee (0.8/1000 h) and thigh (0.5/1000 h), and during game time was to the knee (4.4/1000 h) and head (2.2/1000 h). In total, the location for the highest injury incidence was the knee with 1.5 injuries/1000 h of football. The majority of injuries (82%) were localized to the lower extremities. Sixty-six injuries (28%) were re-occurring injuries (re-injuries). The incidence of traumatic injuries was 3.3/1000 h of football and for overuse injuries 1.3/1000 h. Overuse injuries occurred mainly during the preseason and at the beginning of the spring season. Thirty-nine percent of the injuries were slight or minor causing absence from practice or game time of less than 1 week, 39% were moderate (absence 7-28 days) and 22% were major (absence more than 28 days). The major injuries occurred often owing to trauma and were mainly to the knee.
