To examine the effects of an 8-week home-based resistance exercise program on balance, power, and mobility in adults with multiple sclerosis.
Experimental group design.
General community.
Twenty-nine women (age, 50.3+/-8.5 y) and 8 men (age, 51.1+/-7.1 y) were stratified by disability level and age and were randomized into exercise (n=19) and control (n=17) groups.
The exercise group had lower-extremity resistance training 3 times a week. The control group maintained current level of physical activity.Main outcome measures Primary outcome measures included balance, as measured by anteroposterior sway, mediolateral sway, and sway velocity using the AccuSway(PLUS) force platform; mobility as assessed with the Up and Go test; and leg power as assessed with the Leg Extensor Power Rig.
Leg extensor power improved significantly in the exercise group (pretest, 3.19+/-1.36 W/kg; posttest, 3.95+/-1.23 W/kg; P=.004), although measures of balance and mobility did not change.
The home-based resistance program was well tolerated by participants and offered a practical means to improve leg extensor power in a short period of time.
研究一项为期8周的居家抗阻运动计划对成年多发性硬化症患者平衡能力、力量和活动能力的影响。
实验组设计。
普通社区。
29名女性（年龄50.3±8.5岁）和8名男性（年龄51.1±7.1岁），按残疾程度和年龄分层，随机分为运动组（n = 19）和对照组（n = 17）。
运动组每周进行3次下肢抗阻训练。对照组维持当前的身体活动水平。主要结局指标主要结局指标包括平衡能力，采用AccuSway（PLUS）测力平台测量前后晃动、内外侧晃动和晃动速度；活动能力通过起身行走测试评估；腿部力量通过腿部伸肌力量测试装置评估。
运动组的腿部伸肌力量显著提高（预测试，3.19±1.36瓦/千克；后测试，3.95±1.23瓦/千克；P = 0.004），尽管平衡能力和活动能力的测量结果没有变化。
参与者对居家抗阻计划耐受性良好，该计划为在短时间内提高腿部伸肌力量提供了一种实用方法。
