Résumé
Objectives
Shoulder tendinopathy is a common musculoskeletal disorder associated with persistent pain and functional disability. Although the relationship between pain and functional impairment has been investigated in other disorders, evidence in shoulder tendinopathy remains limited.
Methods
This cross-sectional study included 36 patients with shoulder tendinopathy. Pain and self-reported function were assessed using the Shoulder Pain and Disability Index (SPADI); Shoulder Rating Questionnaire (SRQ); and a prespecified three-time-point Visual Analogue Scale (VAS) protocol. Affected-arm performance was evaluated using the Timed Functional Arm and Shoulder Test (TFAST). Spearman’s rank correlation coefficients (rs) were calculated using a Bonferroni-adjusted significance threshold of α = 0.007.
