RESUMO
OBJECTIVES: To evaluate the efficacy of a three-week period of complex and intensive hand physical therapy on hand function in patients with systemic sclerosis (SSc). METHODS: Thirty-one patients with SSc were treated. Hand stretching exercises, ergotherapy supplemented with thermal and mud baths, whirlpool therapy and soft tissue massage were daily used during a three-week period. The control SSc group (n=22) received similar management for their large joints leaving out their hands. The primary outcomes of this study were the Health Assessment Questionnaire (HAQ) and the Disabilities of the Arm, Shoulder and Hand (DASH). Hand Anatomic Index (HAI), Cochin Hand Function (CHFT) and clinical characteristics were also assessed before starting the therapy and six months afterwards. RESULTS: Six months after the investigation period, only the group receiving hand physical therapy showed improvement in HAQ and DASH scores compared to the baseline values (p<0.05). The improvement in median HAQ value (25%-75% quartiles) reached the clinical meaningful rate (baseline 1.125/0.625-1.625/ versus 0.75/0.25-1.5/ at six months). Visual analogue scales of global pain (p<0.01) and Raynaud's phenomenon (p<0.05) also had better results than at baseline. HAI, gripping strength and CHFT also showed some improvement, but did not reach the significance level of change by the end of the six-month observation period. CONCLUSIONS: The complex physical therapy caused favourable changes in both the HAQ and the DASH indicating that this particular program had some long-term beneficial effect on hand function in patients with SSc.
