摘要
背景:研究发现,骨对频率为15～30Hz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(10min/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。
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.
