- Objectives To evaluate possible changes in spinal curvature over a period of 5 years of an elite cross-country skiing squad, and to study whether there are any differences in this respect between individuals who report low back pain and those how do not. Participants Fifteen young cross-country skiers (M age=13.6±0.9) participated voluntarily throughout the entire study period. Main outcome measures Debrunner's kyphometer was used for measuring the difference between thoracic kyphosis and lumbar lordosis of the spine. All subjects also answered a questionnaire including questions about ski-related low back pain, the amount of ski training, and participation in other sports. Results The results at the end of the 5-year period comprise data from 15 skiers (M age=18.5±0.9 years). The relationship between thoracic kyphosis and lumbar lordosis increased from 3.5° to 13.1°, respectively (p=0.0001). Of the 15 elite cross-country skiers, seven reported low back pain at the 5-year examination. At the 5-year follow-up, skiers with low back pain showed significantly higher relationship between thoracic kyphosis and lumbar lordosis than did those skiers without low back pain, 18.2° and 10.5°, respectively (p=0.035). Of the eight elite cross-country skiers without low back pain, seven were also involved in other sports (p=0.005). Conclusions Based on these findings, our advice is that adolescent cross-country skiers also should participate in other physical activities besides cross-country skiing.

A clinician-friendly test battery with a passing rate similar to a ‘gold standard’ return-to-sport test battery 1 year after ACL reconstruction: Results from a rehabilitation outcome registry
- 2023
-
In: Physical Therapy in Sport. - : Elsevier BV. - 1466-853X. ; 59, s. 144-150
-
Journal article (peer-reviewed)abstract
- Objectives: To 1) present passing rates for different clinician-friendly (CF) test batteries and 2) determine the relationship between passing CF test batteries and passing gold standard (GS) return-to-sport (RTS) muscle function testing, 1 year after ACL reconstruction. Study design: Cross-sectional registry study, level of evidence: 3. Setting: Primary care. Participants: Data from 588 patients (52% women, mean age 29.3 ± 9.8 years) were extracted from the Project ACL registry. Main outcome measures: The passing rates for the different test batteries. Results: The passing rate for GS test battery was 28% (95% CI, 24–32%) and the passing rate for the CF test battery with the lowest passing rate was 27% (95% CI 24–31%). The two CF test batteries with the strongest relationships with passing GS test battery showed that 51% (95% CI 43–59%) and 49% (95% CI 44–55%) of the patients who passed the respective CF test battery also passed the GS test battery. Conclusion: A CF test battery can be as demanding to pass as a GS test battery, 1 year after ACL reconstruction. However, passing a CF test battery only gives patients a chance similar to a “coin flip” of also passing a GS RTS test battery.

Journal article (peer-reviewed)abstract
- ObjectivesTo determine the incidence and prevalence of significantly interrupting shoulder pain (SIP) in young surf lifesavers and to determine association with training dosage and the ‘combined elevation test’.Participants54 surf lifesavers aged 10 – 18 from the Gold Coast, Australia.Methods and Outcome MeasuresRetrospective survey of SIP and training dosage. Cross-sectional measures of the combined elevation test.DesignRetrospective.Results56.5% of female surf lifesavers reported a history of SIP compared to males with 48.5%. Females had a higher combined elevation score compared to males, 28.32±SD8.52cm and 26.09±SD6.64cm, respectively. Young surf lifesavers had an incidence rate of 2.1 SIP episodes per thousand hours of training, an incidence proportion of 51.9% and prevalence of 18.5%. Combined elevation had low level positive trends with training dosages and statistically significant negative correlation with board paddling sessions per week (r= -0.287, p=<0.05). Those with a history of SIP had a statistically significant higher number of sessions (p=0.008), duration (p=0.015) and distance (p=0.005) swimming per week.ConclusionYoung surf lifesavers with a history of SIP have greater swimming dosage not associated with decrease in combined elevation score. More board paddling sessions per week decreased the combined elevation score of young surf lifesavers.

Frontal plane kinematics predict three-dimensional hip adduction during running
- 2017
-
In: Physical Therapy in Sport. - : Elsevier BV. - 1466-853X. ; 27, s. 1-6
-
Journal article (peer-reviewed)abstract
- Objectives To investigate if frontal plane kinematics are predictive of three dimensional (3D) hip adduction and hip internal rotation during running. Study design Cross-sectional. Setting Biomechanics laboratory. Participants Thirty healthy male runners aged 18–45 years. Main outcome measures Two dimensional (2D) angles in the frontal plane (peak pelvic obliquity, peak hip adduction, peak femoral valgus, peak knee valgus and peak tibial valgus) and 3D hip adduction and hip internal rotation during stance phase of running were obtained. Results Linear regression modelling revealed that peak 2D pelvic obliquity (a drop towards the contralateral leg) and peak femoral valgus significantly predicted 88% of the variance in peak 3D hip adduction (p < 0.001). Frontal plane kinematics however, were not predictive of peak hip internal rotation in 3D (p > 0.05). Conclusions Frontal plane kinematics, specifically contralateral pelvic drop and femoral valgus, predicted the vast majority of the variance in 3D hip adduction during the stance phase of running. This indicates that 2D video may have potential as a clinically feasible proxy for measurement of peak 3D hip adduction – a risk factor for patellofemoral pain.

- 2024
-
In: Physical Therapy in Sport. - : Elsevier. - 1466-853X .- 1873-1600. ; 68, s. 22-30

Journal article (peer-reviewed)abstract
- Objective: To determine the relative contribution of each of the following aspects: demographics, physical function, and patient-reported outcome measures (PROMs), including both physical and psychological constructs, to return to sport (RTS) (any level) one-year post anterior cruciate ligament reconstruction (ACLR). Design: Cross-sectional cohort study.Methods: We included data for 143 participants (73 women, mean (SD) age 24 (5.8) years) ∼ one-year post-ACLR. Data comprised demographics, physical function (hop performance, hip and knee peak torque) and PROMs (Knee Osteoarthritis Outcome Score subscales, perceived stress, and ACL Return to Sport after Injury scale (ACL-RSI)). We then used a Z-normalized multivariable logistic regression model to establish the relative contribution of factors associated with RTS.Results: Sixty-four (45%) of the participants had returned to sport at one year post-ACLR. In the regression model, greater hip abduction peak torque (OR = 1.70, 95% CI; 1.01 to 2.84) and greater psychological readiness to RTS (OR = 2.32, 95% CI; 1.30 to 4.12) were the only variables associated with RTS (R2 = 0.352).Conclusions: The significant contribution of hip abduction strength and psychological readiness to RTS was still relatively small, suggesting other potential factors explaining RTS which may not be captured by common RTS criteria.

Factors affecting knee abduction during weight-bearing activities in individuals with anterior cruciate ligament reconstruction
- 2019
-
In: Physical Therapy in Sport. - : Elsevier BV. - 1466-853X. ; 38, s. 8-15
-
Journal article (peer-reviewed)abstract
- Objective: To investigate if muscle strength and muscle activation patterns are associated with increased knee abduction during two functional tasks, commonly used in rehabilitation for individuals with anterior cruciate ligament reconstruction (ACLR). Design: Cross-sectional study. Setting: Laboratory. Participants: 24 women and 29 men approximately 7 months after ACLR. Main outcome measures: Isometric peak torque of the trunk and lower extremity muscles were determined during maximal voluntary contractions. Trunk and lower extremity average muscle activation amplitude and peak knee abduction were evaluated during the single-leg squat (SLS) and the single-leg hop for distance (SLHD) for the injured side. Separate backward regressions were performed for men and women. Results: In women, lower knee flexion and extension strength were associated with greater peak knee abduction during the SLS (B = 4.63–18.26, p ≤ 0.036); lower knee flexion strength and iliocostalis activation on the non-injured side were associated with greater peak knee abduction during the SLHD (B = 0.60–20.48, p ≤ 0.043). No associations between muscle function and peak knee abduction were found in men. Conclusions: Muscle function may contribute differently to knee abduction in men and women after ACLR. This should be considered when designing rehabilitation programs to reduce knee abduction in these patients.

Extending in-competition Athletics injury and illness surveillance with pre-participation risk factor screening: A pilot study
- 2015
-
In: Physical Therapy in Sport. - : Elsevier. - 1466-853X .- 1873-1600. ; 16:2, s. 98-106
-
Journal article (peer-reviewed)abstract
- Objectives: To explore the performance of retrospective health data collected from athletes before Athletics championships for the analysis of risk factors for in-competition injury and illness (IandI). Methods: For the 2013 European Athletics Indoor Championships, a self-report questionnaire (PHQ) was developed to record the health status of 127 athletes during the 4 weeks prior to the championship. Physician-based surveillance of in-competition IandI among all 577 athletes registered to compete was pursued during the championships. Results: 74 athletes (58.3%) from the sample submitted a complete PHQ, 21 (28%) of these athletes sustained at least one injury and/or illness during the championships. Training more than 12 h/week predisposed for sustaining an in-competition injury, and a recent health problem for in-competition illness. Among the 577 registered athletes, 60 injuries (104/1000 registered athletes) were reported. 31% of injuries were caused by the track, and 29% by overuse. 29 illnesses were reported (50/1000 registered athletes); upper respiratory tract infection and gastro-enteritis/diarrhoea were the most reported diagnoses. Conclusions: Pre-participation screening using athletes self-report PHQ showed promising results with regard to identification of individuals at risk. Indoor injury types could be attributed to extrinsic factors, such as small track size, track inclination, and race tactics. (C) 2014 Elsevier Ltd. All rights reserved.

Pain neuroscience education in persistent painful tendinopathies: A scoping review from the Tendon PNE Network
- 2023
-
In: Physical Therapy in Sport. - 1466-853X. ; 63, s. 38-49
-
Journal article (peer-reviewed)abstract
- Objective: to conduct and report a scoping review of the available evidence of the effects and content of pain neuroscience education for patients with persistent painful tendinopathies.Methods: PubMed, Embase, Web of Science, CINAHL, SPORTDiscus, and grey literature databases were searched from database inception to May 2022. Randomised and non-randomised controlled trials, non-controlled clinical trials, cohort studies, case series, case studies including people with persistent painful tendinopathy aged & GE;18 years, a pain education intervention, and in English were included. Studies were excluded if they were crosssectional studies, reviews, editorials, abstracts, or full-text not available or if included heterogeneous study cohorts, patients with tendon rupture, or patients with systemic diseases.Results: five studies (n = 164) were included. Pain neuroscience education entailed face-to-face discussion sessions or educational materials including videos, brochures, paper drawings, and review questions. All studies used pain neuroscience education in conjunction with other interventions, obtaining significant benefits in outcomes related to pain, physical performance, or self-reported function, among others.Conclusions: The application of pain neuroscience education in conjunction with other interventions seemed to improve several outcomes. However, considering the current knowledge about tendon pain and the scarcity of well-designed trials studying pain neuroscience education in tendinopathy, additional research is needed.

Journal article (peer-reviewed)abstract
- ObjectivesTo investigate the accuracy of visual assessments made by physical therapists of lumbo-pelvic movements during the squat and deadlift and how much movement is considered injurious.DesignQuantitative Cross-sectional.Participants14 powerlifters, 10 Olympic weightlifters and six physical therapists.SettingThe lifters were recorded simultaneously by video and an inertial measurement unit (IMU) system while performing squats and deadlifts. The physical therapists assessed the videos and rated whether specific lumbo-pelvic movements were visible during the lifts and whether the movement amplitude was considered injurious.Main outcome measuresThe nominal visual assessments, if there was a movement and if it was considered injurious, were compared to the degrees of movement attained from the IMU system.ResultsDuring the squat, a posterior pelvic tilt of ≥34° was required to visually detect the movement. For other lumbo-pelvic movements, there was no significant difference in the amount of movement between those who were assessed as moving or not moving their lumbo-pelvic area, nor was there a difference in movement amplitude between those who were assessed as having an increased risk of injury or not.ConclusionsPhysical therapists did not consistently detect lumbo-pelvic movements during squats and deadlifts when performed by competitive lifters.

Clinical methods to quantify trunk mobility in an elite male surfing population
- 2016
-
In: Physical Therapy in Sport. - : Elsevier. - 1466-853X .- 1873-1600. ; 19, s. 28-35
-
Journal article (peer-reviewed)abstract
- BackgroundHigh numbers of acute shoulder and chronic lumbar injuries have been identified in a surfing population. A simple screening tool could be used to determine whether thoracic spine dysfunction is a possible contributor to shoulder or lumbar injuries. Importantly, thoracic mobility in the sagittal and horizontal planes are key requirements in the sport of surfing; however to date the normal values of these movements have not yet been quantified in a surfing population.ObjectivesTo develop a reliable method to quantify thoracic mobility in the sagittal plane; to assess the reliability of a thoracic rotation method, and quantify thoracic mobility in an elite male surfing population.DesignClinical Measurement, reliability (repeated measures) and comparative study. Methods: 27 subjects were used to determine the reliability of a new method to assess thoracic mobility in the sagittal plane and 30 subjects were used to confirm the reliability of an existing thoracic rotation method. A total of 15 elite surfers were used as part of a comparative analysis with age and gender matched controls. Results: Intra-rater reliability (within and between session) intraclass correlation coefficient (ICC) values ranged between 0.95 - 0.99 for both thoracic methods in the sagittal plane and between 0.95 – 0.98 for the rotation method. There was no significant difference in the amount of thoracic mobility in the sagittal plane between groups; however the elite surfing group had significantly (p ≤ 0.05) greater rotation than the comparative group (mean rotation 63.57° versus 40.80° respectively). Symmetry was also confirmed between left and right thoracic rotation in the elite surfing group (63.06 versus 64.01). Conclusion: This study has illustrated reliable methods to assess the thoracic spine in the sagittal and horizontal planes. It has also quantified ROM in a surfing cohort; identifying thoracic rotation as a key movement. This information may provide clinicians, coaches and athletic trainers with imperative information regarding the importance of maintaining adequate thoracic rotation and symmetry. From a screening perspective thoracic rotation should be assessed for performance purposes and to limit the potential for injury in the thoracic spine or in surrounding regions.
