摘要：

背景：研究发现，骨对频率为15~30 Hz的动态应变比较敏感。在此频率范围内，很小的应变也能产生较大的成骨反应。
目的：通过人体振动实验，观察振动对骨与关节病的影响。
方法：以60例20~75岁患有骨与关节疾病的青、中和老年患者为观察对象，按随机原则分为振动组和对照组。振动组进行3个月(10 min/d，每周5次)的全身振动实验。对照组保持日常生活模式，不予振动治疗。观察患者的膝关节功能、下肢肌力、关节活动范围以及骨密度等指标在3个月内的变化趋势。
结果与结论：60例受试者均进入结果分析。振动组在振动治疗3个月后腰椎的骨密度明显增加，比实验前平均增加了1.2%  (P < 0.05)，股骨颈骨密度和股骨颈抗骨折能力分别增加了0.85%和2.81%(P < 0.05)，膝关节有效活动范围平均增加了9.52% (P < 0.05)，双下肢最大肌力平均增加了13.2%(P < 0.01)。提示全身振动疗法可以提高骨密度和有效改善膝关节各项指标。

Abstract:

BACKGROUND: Bone is sensitive to dynamic strain between 15 and 30 Hz.
OBJECTIVE: To observe the beneficial influence of vibration on the bone joint disease.
METHODS: A total of 60 patients, aged 20-75 years, with bone joint diseases were randomly assigned to vibration group and control group. Whole body vibration training (3 months, 10 min/d, 5 d/week) was performed in vibration group, while the control group was kept normal life as usual. The knee function, muscle strength of lower limbs, range of motion, and bone mineral density (BMD) in 3 months were observed.
RESULTS AND CONCLUSION: A total of 60 patients were included in the final analysis. BMD of the vibration group increased obviously after vibration training (+1.2% for vertebrae and + 0.85% for femur neck, P < 0.05). Ability of femur neck to fight bone fracture increased 2.81% (P < 0.05). Effective range of knee joint motion increased 9.52% (P < 0.05) and muscle max strength of lower limbs increased 13.2% (P < 0.01). Experiment results indicate that the whole body vibration training can increase BMD and improve every index sign of knee joint.
