- 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.

- 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.

- 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.

- 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.

- 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.

- 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.

- OBJECTIVE: To study normative values of range of motion (ROM), strength, and functional performance and investigate changes over 1 year in adolescent female football players.DESIGN: Cross-sectional.PARTICIPANTS: 418 adolescent female football players aged 12-17 years.MAIN OUTCOME MEASURES: The physical characteristic assessments included (1) ROM assessment of the trunk, hips, and ankles; (2) strength measures (maximal isometric and eccentric strength for the trunk, hips, and knees, and strength endurance for the neck, back, trunk and calves), and (3) functional performance (the one-leg long box jump test and the square hop test).RESULTS: Older players were stronger, but not when normalized to body weight. Only small differences in ROM regarding age were found. ROM increased over 1 year in most measurements with the largest change in hip external rotation, which increased by 6-7° (Cohen's d = 0.83-0.87). Hip (d = 0.28-1.07) and knee (d = 0.38-0.53) muscle strength and the square hop test (d = 0.71-0.99) improved over 1 year.CONCLUSIONS: Normative values for ROM and strength assessments of neck, back, trunk, hips, knees, calves and ankles are presented for adolescent female football players. Generally, fluctuations in ROM were small with little clinical meaning, whereas strength improved over 1 year.

- Objective: To study the side hop test regarding validity, reliability, and quality in relation to sex, age and ACL-reconstruction in soccer players.Design: Cohort study. Participants: 117 females with a primary ACL-reconstruction, and 119 females, 46 males (age 16-26 years), 49 girls and 66 boys (age 13-16 years) without injury.Main outcome measures: For convergent validity, one physiotherapist analysed side hops live and later on video. One physiotherapist and two physiotherapy students analysed side hops from 92 players for interrater reliability (video). For intrarater reliability, side hops from 35 players were analysed twice (video). Quality aspects (flaws), i.e. number of times the hopping limb touched the strips, the nonhopping limb touched the floor, and double hops/foot turns with the hopping limb, were registered (video).Results: Convergent validity was excellent; the intraclass correlation coefficient (ICC) was 0.93-1.0. All reliability measures were excellent (ICC 0.92-1.0). Adult male players had fewest and girls had most flaws, especially double hops/foot turns with the hopping limb, compared with all other players (mean, 11-12 vs 1-6, h2 = 0.18, large effect size). No differences were reported between knee-healthy and ACLreconstructed females.Conclusion: The side hop test is valid and reliable. Quality aspects differ between sexes and ages.& COPY; 2023 The Authors. Published by Elsevier Ltd.

- Objectives: To evaluate knee joint position sense (JPS) among individuals with anterior cruciate ligament reconstruction (ACLR), cleared for return to sport, and investigate whether JPS errors are associated with outcomes of a functional obstacle clearance test (OC; downward vision occluded).Design: Cross-sectional.Setting: Controlled laboratory.Participants: Thirty-four individuals following ACLR, 23 non-athletic asymptomatic controls (CTRL), 18 athletes (ATH).Main outcome measures: absolute error (AE) and variable error (VE) for weight-bearing knee JPS (target angles: 40°, 65°); minimal distances of the lower extremity from the obstacle (at any time and vertical clearance; two obstacle heights).Results: Larger AE (P = 0.023) and VE (P = 0.010) were observed for CTRL compared with ACLR. CTRL also had larger OC distances for the trailing leg compared with ATH (P ≤ 0.046) and greater variability compared to both other groups (P ≤ 0.033). Moderate positive correlations (Rs ≥ 0.408, P ≤ 0.029) were observed between AE for the 40° angle and low-obstacle distances, for the injured ACLR leg.Conclusions: Knee JPS was worse in less-active individuals rather than following ACLR. Functional assessments like our OC test should complement isolated JPS tests, as they emphasize whole-body coordination and thus constitute more relevant estimations of proprioception.
