Abstract
OBJECTIVE: To compare psychological factors and the number of painful sites between wheelchair basketball athletes (WBA) with and without shoulder pain and examine their associations with shoulder pain. DESIGN: A cross-sectional, case-control study. METHODS: Forty-three WBA participated. Shoulder pain was assessed with the Wheelchair User's Shoulder Pain Index (WUSPI), pain catastrophizing with the Pain Catastrophizing Scale (PCS), kinesiophobia by the Tampa Kinesiophobia Scale (TKS), self-efficacy with the General Self-Efficacy Scale (GSES), and the number of painful sites using the Nordic Musculoskeletal Questionnaire. Disability and sport-related data were collected. Spearman's correlation coefficients were calculated. Mann-Whitney U and independent samples t-tests were used for between-group comparisons. RESULTS: Athletes with shoulder pain (n = 21) had an increased number of painful sites (P < .050) and higher PCS (P = .003). The WUSPI exhibited moderate associations with the number of painful sites during the last year (rho = .581) and past seven days (rho = .602), and PCS (rho = .470), and a weak association with the TKS (rho = .333)(P < .050). The number of painful sites with disability exhibited moderate associations with PCS (rho = .427) and GSES (rho = -.473)(P < .050). WBA classification levels showed moderate associations with the WUSPI (rho = -.400) and the number of painful sites during the last year (rho = -.437), and a weak association with the number of painful sites during past seven days (rho = -.315)(P < .050). The PCS showed weak associations with the number of painful sites during the last year (rho = .365) and the past seven days (rho = .398)(P < .050). CONCLUSIONS: Results suggest considering WBA classes, pain catastrophizing, self-efficacy and multisite pain in the pain management of WBA.
