類風濕關節炎病人肌力變化力探討：電腦肌電圖分析

Abstract

Weakness and atrophy of skeletal muscles are found commonly in patients suffering from rheumatoid arthritis, but the reasons of this phenomenon are still questionable.39 RA patients and 35 normal persons, as control group, were examed in 2 aspects: 1)Maximal muscle strength including grasp, 3 jaw-chuck and palmar abduction of thumb; 2)Evoked uscle action potential(EMAP) of APB, using computer measurement of the amplitude, duration and surface. (1,2)V Besides, functional class, stage of bony change, duration of the disease, medication, painful joints were also taken into consideration. Comparison between the muscle strength and the quantified EMAP in RA patients and control group revealed. 1) Poor correlation between muscle strength and EMAP 2) no statistically significant difference of quantified EMAP between normal persons and patients with rheumatoid arthritis; therefore, the quantified EMAP (with computerized EMG) is not an ideal method of screening or evaluating the muscle strength changes in patients with reheumatoid arthritis. The results also revealed that joint deformity, disuse atrophy or medication seemed not the main reasons of muscle weakness in rehumatoid arthritic patients, except pain.
