The fear of re-injury may persist after anterior cruciate ligament (ACL) reconstruction (ACLR) in professional soccer players (PSPs) even after a successful return to sport (RTS). This study aimed to determine the extent of this fear of re-injury and the impact of demographic variables and this fear of re-injury on the lower extremity functional scale (LEFS) scores in PSPs who had completed a successful RTS following ACLR. A cross-sectional survey design was used. Sixty-seven PSPs who had successfully RTS after ACLR, completed a demographic information sheet, the Athlete Fear-Avoidance Questionnaire (AFAQ), and the LEFS. The average AFAQ scores indicated low fear (M = 10.2, SD = 6.7), while high LEFS scores were observed (M = 67.1, SD = 12.4). There were significant strong negative correlations between LEFS and body mass index (BMI; rs [65] = -0.501, P = .001) and AFAQ and BMI (rs [65] = -0.378, P = .001). A hierarchical linear regression analysis found AFAQ to be a significant predictor of LEFS (b = -0.92, s.e. = 0.19, P = .001), with a total variance (adjusted R2) of 32.9%. PSPs' fear of re-injury post-ACLR significantly reduced their perceived levels of lower limb functionality. This study highlights the need to further explore and develop strategies to manage PSP fear of re-injury to improve sports-related performance post-ACLR.
This study aimed to investigate the prevalence of upper limb musculoskeletal disorders (MSDs) and their association with smartphone addiction and smartphone usage among university students in the Kingdom of Saudi Arabia during the COVID-19 pandemic. A total of 313 university students aged 18 years and older who owned a smartphone and used it during the preceding 12 months participated in this cross-sectional study. The prevalence of upper limb MSDs, smartphone addiction/overuse, and levels of physical activity were recorded using the standardized Nordic musculoskeletal questionnaire, the smartphone addiction scale (short version), and the international physical activity questionnaire (short form), respectively. Data collection was performed on campus between March and May 2021. Binary logistic regression was used to determine the association between the prevalence of upper limb MSDs and smartphone addiction/overuse and levels of physical activity. The 12-month prevalence of MSDs of the shoulder, elbow, and wrist/hand regions due to smartphone use among participants was found to be 20.13%, 5.11%, and 13.42%, respectively. Shoulder (odds ratio (OR) = 11.39, 95% confidence interval (CI) = 4.64−27.94, p < 0.001), elbow (OR = 15.38, 95% CI = 1.92−123.26, p = 0.01), and wrist/hand MSDs (OR = 7.65, 95% CI = 2.75−21.22, p < 0.001) were more prevalent among participants who were categorized as having smartphone addiction/overuse measures. Promoting awareness about the healthy use of smartphones, including postural education and decreasing screen time, is necessary to reduce smartphone-related MSDs.
