Background For patients with systemic sclerosis (SSc), hand involvement is an underrated clinical manifestation. Therefore, the aim of this study was to investigate the efficacy of a hand exercise program and to demonstrate its effect on hand function, quality of life, anxiety, and depression in patients with SSc. Methods This study was designed as a single blind, randomized controlled comparative study. Sixty-two female patients with SSc were randomized into an exercise group (n = 32) or a control group (n = 30). After some were lost to follow-up, 25 patients were analyzed in each group. In the exercise group, the 8-week intervention consisted of isometric hand exercises and self-administered stretching repeated 10 times/2 sets per day. All patients were assessed using the Hand Mobility in Scleroderma (HAMIS) test, the Duruoz Hand Index (DHI), grip strength, the 36-item short form, Health Assessment Questionnaire-Disability Index (HAQ-DI), Beck Anxiety Inventory (BAI), and the Beck Depression Inventory (BDI) at baseline and then again 4 and 8 weeks later. Within-group comparisons over time were analyzed using the Friedman test. Post hoc analysis was performed using the Wilcoxon signed rank test. A multiple linear regression analysis was used to define the impact of exercise on clinical status. Results Of the 50 total patients, the median age and the median body mass index were 55.5 years and 25.9 kg/m(2). The median disease duration was 10.0 years. Thirty-four patients (68.0%) were diffuse cutaneous systemic sclerosis (dcSSC), whereas 16 (32.0%) were limited cutaneous systemic sclerosis (lcSSc). The primary outcome of handgrip strength, as well as the HAMIS, DHI, HAQ-DI, and BDI, significantly improved over time (p < 0.001, p < 0.001, p < 0.001, p < 0.001, and p = 0.005, respectively). The between-group comparison indicated significant improvement in DHI, handgrip strength, HAQ-DI, BAI, and BDI in the exercise group (p = 0.02, p = 0.013, p < 0.001, p = 0.015, and p = 0.036, respectively). In the multiple linear regression analysis, exercise was found to be the most efficient factor affecting the improvement in HAMIS, DHI, HAQ-DI, and grip strength. Conclusions The 8-week intervention composed of isometric hand exercises and self-administered stretching provided a significant improvement in handgrip strength, general health, quality of life, and psychological status for patients with SSc.
