Context: Core stability training has been recommended as a vital element in improving movement’s pattern and athletic performance. The main objective of this study was to investigate the effect of 12-week McGill core stability training on movement patterns, shooting accuracy, and throwing performance. Design: Randomized controlled clinical trial. Setting: University research laboratory. Methods: Forty male basketball players were randomly assigned to experimental and control groups. The experimental group completed 12-week McGill core stability training, while the control group completed routine exercise training. Patterns of functional movements was measured through functional movement screen (FMS), shooting accuracy measured by static 3-point shooting (S3P) and dynamic 60-second 3-point shooting test, and throwing performance measured by Functional Throwing Performance Index. Results: Comparison revealed that regardless of received training, after 12 weeks both groups showed significant improvement in all outcome measures. However, experimental group had significantly higher post test scores in FMS (P = .02), S3P (P = .007), and dynamic 60-second 3-point shooting test (P = .01). For Functional Throwing Performance Index, there was no group differences (P = .96). The results of follow-up assessments showed for all measurements including FMS (P = .03), S3P (P = .004), dynamic 60-second 3-point shooting test (P < .001), and Functional Throwing Performance Index (P = .005); experimental group had higher scores than the control group. Conclusions: According to the results, implementing McGill core stability training in basketball routine training would be advisable since significant improvement can be obtained in the measured parameters.

Background: The Anterior Cruciate Ligament-Return to Sport after Injury scale (ACL-RSI) is used to measure athletes’ psychological readiness in terms of their emotions, confidence in performance, and risk appraisal with respect to return to sport after ACL reconstruction. Objective: To translate and cross-culturally adapt the ACL-RSI to the Persian version and evaluate the reliability and validity of this scale in patients with ACL reconstruction. Study Design: Clinical measurement study (psychometric analysis). Methods: To assess test–retest reliability, 100 participants were asked to complete the Persian version of the ACL-RSI 2 times with a 7- to 10-day interval. In the first assessment, the patients also filled the Injury-Psychological Readiness to Return to Sport Questionnaire, Tampa Scale of Kinesiophobia, International Knee Documentation Committee Subjective Knee Form, and Knee Injury and Osteoarthritis Outcome Score. Internal consistency (Cronbach alpha, α), test–retest reliability (intraclass correlation coefficients), measurement error (standard error of measurement and minimum detectable change), and construct validity (Pearson r) were determined. Results: Our results showed good internal consistency (Cronbach alpha = .94) and excellent test–retest reliability (intraclass correlation coefficients = .90 (.85−.93)]. Standard error of measurement and minimum detectable change were 4.64 and 12.85, respectively. No significant bias was observed between test and retest. In addition, based on the results of correlation analysis, all hypotheses of this study were confirmed. The Persian version of the ACL-RSI had a strong correlation with Injury-Psychological Readiness to Return to Sport (I-PPR) (P < .001, r = .76) and Tampa scale of Kinesiophobia (TKS) (P < .001, r = −.68). Furthermore, a moderate correlation was observed between the Persian version of the ACL-RSI and the International Knee Documentation Committee Subjective Knee Form (P < .001, r = .44) and between this version of the ACL-RSI and the subscales of Knee Injury and Osteoarthritis Outcome Score (P < .001, r = .30–.55). Conclusion: Given its acceptable reliability and validity, the Persian version of the ACL-RSI seems to be a suitable tool for evaluating psychological readiness to return to sport after ACL reconstruction.
