[Purpose] This study investigated the effect of the Weight-bearing Exercise for Better Balance program on the strength of hip flexors, extensors, abductors, adductors, and knee flexors and extensors and balance in osteopenia. [Subjects and Methods] Twenty-four postmenopausal females with osteopenia volunteered to participate in this study and were randomly assigned into two equal groups of 12: the experimental and control groups. The Weight-bearing Exercise for Better Balance program was applied to the experimental group, while the control group did not receive any treatment. Isokinetic peak torque per body weight values of the hip flexors, extensors, abductors, adductors, and knee flexors and extensors were measured by Biodex System 3 isokinetic dynamometer for both groups before and after six weeks of the program. Balance was assessed in both groups using the Berg Balance Scale. [Results] There was a statistically significant increase in post-intervention mean values of all measured variables compared with pre-intervention values in the experimental group. Also, there was a statistically significant increase in post-intervention mean values of all measured variables except for those of the hip extensors in the experimental group compared with the control group. [Conclusion] The weight-bearing exercise for better balance program has significant effects on lower extremity muscle strength and body balance in postmenopausal females with osteopenia.
[目的] 本研究调查了负重锻炼改善平衡能力方案对骨质减少患者髋部屈肌、伸肌、外展肌、内收肌以及膝部屈肌和伸肌力量及平衡能力的影响。[对象与方法] 24名患有骨质减少的绝经后女性自愿参与本研究，并被随机分为两组，每组12人：实验组和对照组。实验组采用负重锻炼改善平衡能力方案，而对照组不接受任何治疗。在该方案实施六周前后，使用Biodex System 3等速测力计测量两组受试者髋部屈肌、伸肌、外展肌、内收肌以及膝部屈肌和伸肌的每体重等速峰值扭矩值。使用Berg平衡量表对两组的平衡能力进行评估。[结果] 与干预前相比，实验组所有测量变量的干预后平均值有统计学显著增加。此外，与对照组相比，实验组除髋部伸肌外所有测量变量的干预后平均值有统计学显著增加。[结论] 负重锻炼改善平衡能力方案对患有骨质减少的绝经后女性的下肢肌肉力量和身体平衡有显著影响。
