A strain gauged torsion dynamometer linked to a microprocessor was used to assess the dynamic qualities of isometric grip strength in patients with rheumatic diseases. Maximum grip strength, time to maximum grip, and percentage fatigue provide independent information on the grip. Time to maximum grip does not appear to be an objective correlate of subjective stiffness. The usefulness of these dynamic variables for the assessment of stiffness appears limited in arthritic disease, where pain may interfere with the maximum voluntary effort of the test.
使用连接到微处理器的应变片式扭力测力计来评估风湿性疾病患者等长握力的动态特性。最大握力、达到最大握力的时间和疲劳百分比提供了关于握力的独立信息。达到最大握力的时间似乎并非主观僵硬程度的客观相关指标。在关节炎疾病中,疼痛可能会干扰测试中的最大自主努力,这些动态变量在评估僵硬程度方面的作用似乎有限。
