The main objectives of this experimental case series were to evaluate the feasibility of a modified dance-based exercise program with low ground impacts in persons with rheumatoid arthritis (RA) functional class III and to describe its effects on locomotor ability. The relationship between 3 locomotor tests and their responsiveness also were addressed.
Ten female subjects participated in an 8-week exercise program. Locomotor ability was measured before and after the program using the 50-foot test of walking time, the 6-minute test of walking distance, and the locomotion biomechanical analysis.
All subjects showed a high compliance (92.5% presence at sessions) over the 8 weeks of exercise without any aggravation in disease status. They were able to train efficiently at moderate intensity up to 25 minutes. Significant improvements were found in locomotor ability, with a higher responsiveness measured by the locomotion biomechanical analysis, followed by the 6-minute gait test and the 50-foot gait test. Inconsistent relationships between tests suggested that different locomotor abilities are required during tests.
These results support the feasibility of a modified dance-based exercise program for persons with severe RA. With high levels of responsiveness, the detailed biomechanical analysis and the 6-minute gait test are recommended for the assessment of locomotor ability.
本实验性病例系列的主要目的是评估一种针对类风湿关节炎（RA）功能分级为III级患者的低地面冲击力改良舞蹈锻炼方案的可行性，并描述其对运动能力的影响。还探讨了3种运动测试之间的关系及其反应性。
10名女性受试者参加了为期8周的锻炼方案。在方案前后使用50英尺步行时间测试、6分钟步行距离测试和运动生物力学分析来测量运动能力。
所有受试者在8周的锻炼过程中均表现出高依从性（92.5%出席课程），且疾病状态无任何加重。他们能够以中等强度有效训练长达25分钟。运动能力有显著改善，通过运动生物力学分析测量的反应性更高，其次是6分钟步态测试和50英尺步态测试。测试之间不一致的关系表明测试期间需要不同的运动能力。
这些结果支持了为重度RA患者制定改良舞蹈锻炼方案的可行性。鉴于高反应性，建议采用详细的生物力学分析和6分钟步态测试来评估运动能力。
