【摘要】：目的探讨全身振动训练对老年人骨密度(BMD)、下肢肌力和膝关节活动度的影响。方法将入选的76例老年人按性别分组,组内随机分为训练组和对照组。观察振动训练前后腰椎L2~L4和股骨颈的BMD、下肢肌力、膝关节活动度变化。结果 (1)训练组腰椎L2~L4和股骨颈BMD均有不同程度提高,对股骨颈BMD效果略好于腰椎L2~L4,其中女性股骨颈BMD提升最为显著,对老年女性BMD的效果明显优于老年男性(均P0.05)。(2)训练组下肢肌力、膝关节活动度和抗骨折能力均明显提升,下肢肌力提升最为明显(均P0.05)。结论全身振动训练能提高老年人腰椎及股骨颈BMD,有效提升下肢肌力和改善膝关节活动度。
[Abstract]:Objective to investigate the effects of systemic vibration training on lower limb muscle strength and knee motion in elderly patients with bone mineral density (BMD),). Methods 76 elderly patients were randomly divided into training group and control group. The changes of lower limb muscle strength and knee motion of lumbar L2~L4 and femoral neck were observed before and after vibration training. Results (1) in training group, L2~L4 and BMD of femoral neck were improved to some extent, and the effect on BMD of femoral neck was slightly better than that of L2N L4 of lumbar vertebrae, among which BMD of female femoral neck was the most significant. The effect of BMD on elderly women was significantly better than that of elderly men (P0.05). (2). In training group, the movement of knee joint and the ability of anti-fracture were significantly improved, and the muscle strength of lower extremity was the most obvious (P0.05). Conclusion the whole body vibration training can effectively improve the lower limb muscle strength and knee motion of the elderly with lumbar vertebrae and femoral neck BMD,.
