Telerehabilitation Intervention for Individuals With Shoulder Pain: Randomized Controlled Trial

Introduction: Shoulder pain is a condition of high prevalence in the general population. Studies indicate that physiotherapeutic treatment with exercise is effective in reducing pain and restoring function in patients with shoulder pain. Patients may have difficulty accessing the physiotherapy service due to the cost of treatment, transportation to the service, and long waiting lines. A possible solution is the use of a telerehabiliation intervention to increase access to physiotherapy for shoulder pain patients. Objective: To assess the effectiveness of telerehabilitation when compared to in-person physiotherapy on pain and disability in individuals with persistent rotator cuff related shoulder pain. Methods: This study is a controlled, randomized, blinded clinical trial. A total of 184 individuals with shoulder pain were randomly assigned to two groups. One group received a telerehabiliation intervention and the other group received the in-person intervention. The intervention consisted of strengthening exercises with emphasis on the lateral rotator and scapulothoracic muscles. The primary outcome was pain and disability (SPADI, Shoulder Pain and Disability Index), and the secondary outcomes were pain intensity (NPRS, Numerical Pain Rating Scale), function (DASH questionnaire, Disabilities of the Arm, Shoulder and Hand), self-efficacy (CPSS, Chronic Pain Self-Efficacy Scale), kinesiophobia (Cover Scale), patient expectation of treatment (7-point Likert Scale), and patient self-perceived improvement (Global Change Assessment Scale). All outcomes were measured before and after 12 weeks of treatment (2x/week). Normality of data was verified by Kolmogorov Smirnov's test. Differences between groups were assessed using the mixed linear models including the group × time interaction. The effect size was calculated for the variables between the groups. The significance level was set at 5%.
