- Objective: To investigate associations between postural orientation errors (POEs) in patients undergoing rehabilitation for anterior cruciate ligament reconstruction (ACLR) and patient-reported outcomes (PROMs) at 2-year follow-up.Design: Prospective cohort study.Methods: Fifty-three participants (mean (SD) 27 (6.5) years, 24 women), (mean (range) 7 (4–10) months post ACLR) were included. At baseline, all participants were visually assessed for POEs using a validated test battery. The POE subscales Activities of Daily Living and Sport were used in the analysis. At 2-years, the following PROMs were collected: Global knee function, Knee injury and Osteoarthritis Outcome Score, ACL Quality of Life (QoL), Knee Self-Efficacy Scale (K-SES), and ACL Return-to-Sport after Injury scale.Results: Twenty-one participants answered the questionnaires at 2 years (7 women and 14 men). Worse baseline POE Sport was associated with worse scores on K-SES (rs = –0.435, p ≤ 0.049) and ACL-QoL (rs = −0.467 to −0.576, p ≤ 0.038) at follow-up. No statistically significant associations were observed between POEs and the other PROMs.Conclusion: Postural orientation during the rehabilitation phase may be important for future knee self-efficacy and knee-related QoL after ACLR. Given the small population and low response rate, this result needs to be confirmed in future research.

- Background Studies investigating postural orientation in uninjured youth athletes are scarce. Understanding how postural orientation during functional performance tests change with age in uninjured athletes has the potential to enhance awareness of changes in performance after injury and to set realistic goals for injured athletes. Thus, the aim of this study was to explore postural orientation during functional tasks at early adolescence, and changes in postural orientation from early to middle adolescence and relate this to sex, type of sport and right leg lean body mass (RLLBM). Methods In this cohort study 144 (38% female) youth athletes (mean age 13.5 years, SD 0.3) were included at baseline and 86 of these at follow up 2 years later. Four functional performance tests were visually evaluated for Postural Orientation Errors (POEs) with an ordinal scale, ranging from 0 (good) to 2 (poor), yielding a maximum total POE score of 51, and RLLBM by dual energy X-ray absorptiometry. Results Improvements were observed in the total POE score from baseline to follow-up, median difference - 10 and - 7 (p < 0.001) for female and male athletes, respectively. At follow-up, female athletes had lower total POE score (median 18) than males (median 24) (p = 0.01). There were no differences in POE scores between sports type (team, individual, aesthetic) (p = 0.20-0.98) and no relationship between total POE score and RLLBM (r(s) = 0.09, p = 0.42). Conclusions POEs appear to be quite common in young athletic population, but improvements are achieved over time. At mid-adolescence, female athletes seem to have less POEs than males. Neither sport type nor RLLBM seem to influence postural orientation.

- Objectives: There is limited research on sex differences in postural orientation (ie, alignment between body segments) in people with knee injury measured with a clinically applicable method. An understanding of the relationship between postural orientation and physical function may help guide decision making in rehabilitation. The aims were to evaluate (1) sex differences in visual assessment of Postural Orientation Errors (POEs) and (2) the association between POEs and objective and patient-reported physical function, in men and women with anterior cruciate ligament reconstruction (ACLR).Methods: Twenty-four women and 29 men (mean 26.7 (SD 6.5) years) with ACLR were included. Six POEs (lower extremity and trunk) were scored from a video of five tasks with varying difficulty to compute POE scores (total and subscores). Objective physical function was evaluated with the single-leg hop for distance and side hop. Patient-reported physical function was evaluated using patient-reported outcome measures (PROMs).Results: Women had significantly more POEs than men (median difference 5.5-25, p≤0.028). More POEs were associated with shorter hop distance and fewer side hops in women (r s = -0.425 to -0.518, p<0.038), but not in men (r s <0.301, p>0.05). No associations were found between POE scores and PROMs, in either sex (r s < -0.246, p>0.05).Conclusions: Women with ACLR seem to have more POEs compared with men, indicating worse postural orientation. More POEs were associated with worse hop performance, suggesting that POE scores may be used as criteria for rehabilitation progression. The lack of associations between POE scores and PROMs indicate that these measures complement each other.

- Background: Different test procedures are often used within performance-based measures, causing uncertainty as to whether results can be compared between studies. Thus, the aim of this study was to assess agreement between different test procedures for the single-leg hop for distance (SLHD) and the single-leg mini squat (SLMS), respectively, two commonly used tasks for assessing deficiency in lower extremity muscle function.Methods: Twenty-three participants (20-42 years) with lower extremity injury performed the SLHD with arms free and with arms behind back, and the Limb Symmetry Index (LSI; injured leg divided by uninjured and multiplied by 100) was calculated. Another group of 28 participants (mean 18-38 years) performed five SLMSs at a pre-defined speed and maximum number of SLMSs during 30 seconds, and were visually observed and scored as either having a knee-over-foot or a knee-medial-to-foot position (KMFP).Results: No systematic difference between test procedures for the LSI of the SLHD was noted (p=0.736), Cohen's kappa = 0.42. The Bland & Altman plot showed wide limits of agreement between test procedures, with particularly poor agreement for participants with abnormal LSI (<90%). Ten participants were scored as having a KMFP during five SLMSs at a predefined speed, while five had a KMFP during maximum number of SLMSs during 30 seconds (p=0.063, Cohen's kappa = 0.56).Conclusions: The moderate agreement between the two test procedures for the SLHD and the SLMS, respectively, indicate that results from these different test procedures should not be compared across studies. SLHD with arms behind back, and five SLMSs at a pre-defined speed, respectively, were the most sensitive procedures to detect individuals with poor functional performance.
