通过对来自骨质疏松性骨折多中心研究的8080名女性数据的横断面分析，描述了老年女性和具有功能不良风险因素的老年女性亚组中神经和神经肌肉功能随年龄的下降。肌肉力量、平衡、步态、体感辨别和反应时间等12项性能测试均随年龄增长而下降。在百分比尺度上，随着年龄的增长，振动阈值下降最快。吸烟、不运动、不喝酒、糖尿病患者和经常跌倒的参与者在年龄调整后的表现比没有这些特征的参与者差。然而，除了少数例外，那些具有和不具有这些特征的人的表现随年龄下降的速度并没有显著差异。
The decline of neurological and neuromuscular function with age in older women and in subgroups of older women with selected risk factors for poor function is described using cross- sectional analyses of data on 8,080 women from the multicenter Study of Osteoporotic Fractures. All twelve performance-based tests of muscle strength, balance, gait, somatosensory discrimination and reaction time declined with increasing age. On a percentage scale, vibration threshold declined the most rapidly with age. Participants who were smokers, physically inactive, nonconsumers of alcohol, diabetics and more frequent fallers had poorer age-adjusted performance than those without these attributes. However, with a few exceptions, the rate of decline in performance with age for those with and without these characteristics did not differ significantly.
