To assess the efficacy of an exercise program aiming to improve balance and muscular strength, for postural control and muscular strength of women with osteoporosis.
Sample consisted of 33 women with osteoporosis, randomized into one of two groups: intervention group, in which exercises for balance and improvement of muscular strength of the inferior members were performed for 8 wks (n = 17, age 72.8 +/- 3.6 yrs); control group, which was women not practicing exercises (n = 16, age 74.4 +/- 3.7 yrs). At baseline and after 8 wks of treatment, postural control was assessed using a force plate (Balance Master, Neurocom), and muscular strength during ankle dorsiflexion, knee extension, and flexion was assessed by dynamometry.
Adherence to the program was 82%. When compared with the control group, individuals in the intervention group significantly improved the center of pressure velocity (P = 0.02) in the modified clinical test of sensory interaction for balance test, center of pressure velocity (P < 0.01), and directional control (P < 0.01) in limits of stability test, isometric force during ankle dorsiflexion (P = 0.01), knee extension (P < 0.01), and knee flexion (P < 0.01).
Balance and strength exercises are effective in improving postural control and lower-limb strength in elderly women with osteoporosis.
评估旨在改善平衡和肌肉力量的运动方案对骨质疏松症女性的姿势控制和肌肉力量的疗效。
样本由 33 名患有骨质疏松症的女性组成，随机分为两组：干预组，进行 8 周的平衡和下肢肌肉力量改善运动（n = 17，年龄 72.8 ± 3.6 岁）；对照组，不进行运动的女性（n = 16，年龄 74.4 ± 3.7 岁）。在基线和 8 周治疗后，使用测力板（Neurocom Balance Master）评估姿势控制，通过动态测力评估踝关节背屈、膝关节伸展和屈曲时的肌肉力量。
对方案的依从性为 82%。与对照组相比，干预组个体在改良临床感觉相互作用平衡测试中的中心压力速度（P = 0.02）、中心压力速度（P < 0.01）和稳定性测试中的方向控制（P < 0.01）显著改善，等长踝关节背屈力（P = 0.01）、膝关节伸展（P < 0.01）和膝关节屈曲（P < 0.01）。
平衡和力量练习可有效改善老年骨质疏松症女性的姿势控制和下肢力量。
