强壮的背部肌肉有助于良好的姿势和骨骼支撑。骨质疏松症是一种代谢性骨骼疾病，不应影响肌肉力量。在这项研究中，我们感兴趣的是比较背伸肌的力量（BES）的阿尔茨海默氏症和正常妇女。55名年龄在40-85岁之间的女性，在符合入选标准后，被诊断患有骨质疏松症，并被推荐开始适当的运动计划。他们都通过我们的骨质疏松症康复计划-运动（ROPE）对他们的姿势、背部和上肢力量以及体力活动评分进行了评估。此外，为了避免疼痛干扰最大努力的应用，我们没有纳入急性背痛受试者或在测试试验期间经历最大努力的背痛受试者。乳腺癌妇女的BES范围为16至65磅（平均值+/- SD，36.5 +/- 15.5），年龄40-59岁，9 - 55 lb（平均值+/- SD，29.9 +/- 10.6），年龄60-69岁，6 - 52 lb（平均值+/- SD，24.3 +/- 10.2），年龄70-79岁，17 - 27 lb（平均值+/- SD，21.2 +/- 4.2），年龄80岁或以上。将这些数据与25名正常妇女的BES进行比较，并对年龄进行统计学调整，结果表明，乳腺癌妇女的BES明显低于正常妇女。一个更大的妇女群体的纵向研究将是巨大的兴趣，以澄清后伸肌的弱点之前，确实，有助于脊柱压缩性骨折。
Strong back muscles contribute to good posture and skeletal support. Osteoporosis, being a metabolic bone disease, should not affect muscle strength. In this study we were interested in comparing the back extensor strength (BES) of osteoporotic and normal women. Fifty-five women ages 40-85 years who had a documented diagnosis of osteoporosis and were referred for initiation of proper exercise programs were included in our study after meeting the inclusion criteria. They all had evaluation of their posture, back and upper extremity strength, and physical activity score through our Rehabilitation of Osteoporosis Program - Exercise (ROPE). In addition, to avoid the interference of pain on application of maximal effort, we did not include subjects with acute back pain or those who experienced back pain with maximal effort during the testing trial. BES for osteoporotic women ranged from 16 to 65 lb (mean +/- SD, 36.5 +/- 15.5) for ages 40-59 years, 9 to 55 lb (mean +/- SD, 29.9 +/- 10.6) for ages 60-69 years, 6 to 52 lb (mean +/- SD, 24.3 +/- 10.2) for ages 70-79 years, and 17 to 27 lb (mean +/- SD, 21.2 +/- 4.2) for ages 80 years or older. Comparison of these data with the BES of 25 normal women, with statistical adjustment for age, demonstrated that the osteoporotic women had significantly lower BES than the normal women. A longitudinal study of a larger group of women would be of great interest for clarifying whether the weakness of back extensors precedes and, indeed, contributes to compression fractures of the spine.
