Five common modes of physiotherapy were applied to a group of normal subjects and to a group of patients with rheumatoid arthritis. The metacarpophalangeal joint stiffness was measured before therapy and immediately afterwards and the results compared. The only statistically significant result was that short-wave diathermy and ultrasound both reduced the amount of energy dissipated in the joints of the patients. No significant changes occurred in the normal group.
对一组正常受试者和一组类风湿性关节炎患者应用了五种常见的物理治疗方式。在治疗前及治疗后立即测量掌指关节的僵硬程度，并对结果进行比较。唯一具有统计学显著意义的结果是，短波透热疗法和超声波疗法均降低了患者关节中耗散的能量。正常组未出现显著变化。
