The aim of the study was to evaluate the effects of a dynamic training program versus a muscle relaxation training program as home exercise in patients with inflammatory rheumatic diseases. Fifty-four patients (mean age 54 years, mean symptom duration 14 years) were randomized to one of the two programs. After personal instructions every patient exercised at home for half an hour, 5 days a week during 3 months. Before and after the interventions, all patients were assessed for health-related quality of life, joint tenderness and physical capacities. The dynamic training group had improved in perceived exertion at the walking test (p < or = 0.05), while the relaxation training group had improved their total Nottingham Health Profile (p < or = 0.01), its subscale for lack of energy (p < or = 0.05), Ritchie's articular index (p < or = 0.05), muscle function of the lower extremities (p < or = 0.01), and arm endurance (p < or = 0.01). Regarding changes in muscle function of the lower extremities during the intervention period, there was a significant difference (p < or = 0.05) between the groups in favour of the relaxation training group. The results of the study thus indicated that progressive muscle relaxation training might improve health related quality of life, reduce joint tenderness and be superior to dynamic muscle training in improving the muscle function of the lower extremities in patients with inflammatory rheumatic diseases. The clinical effects were small and the results have to be interpreted with caution.
本研究的目的是评估动态训练计划与肌肉放松训练计划作为炎症性风湿疾病患者家庭锻炼方式的效果。54例患者（平均年龄54岁，平均症状持续时间14年）被随机分为两个计划中的一组。在接受个人指导后，每位患者每周5天在家锻炼半小时，持续3个月。在干预前后，对所有患者进行健康相关生活质量、关节压痛和身体能力的评估。动态训练组在步行测试中的自觉用力程度有所改善（p≤0.05），而放松训练组在诺丁汉健康量表总分（p≤0.01）、精力不足子量表（p≤0.05）、里奇关节指数（p≤0.05）、下肢肌肉功能（p≤0.01）和手臂耐力（p≤0.01）方面有所改善。关于干预期间下肢肌肉功能的变化，两组之间存在显著差异（p≤0.05），有利于放松训练组。因此，该研究结果表明，渐进性肌肉放松训练可能改善健康相关生活质量，减轻关节压痛，并且在改善炎症性风湿疾病患者下肢肌肉功能方面优于动态肌肉训练。临床效果较小，结果必须谨慎解读。
