We examined how the soleus H-reflex is affected by the changes in limb loading by testing subjects on a body weight support system during standing.
Twenty-two healthy subjects (10 males and 12 females) were recruited for this study. The size of the soleus H-reflex was measured in six different limb loading conditions: 100%, 90%, 80%, 70%, 60%, and 50%. One-way repeated measure ANOVA was used (p<0.05) to compare the H/M ratios among the six different load conditions.
The amplitudes of the soleus H-reflex decreased significantly as the amount of body weight load decreased.
Findings of this study suggest that the levels of body weight load in pre- and post-test conditions should be consistent when H-reflex testing is adapted as an outcome measure of rehabilitation intervention for patients with central nerve system lesion such as partial body weight supported gait training.
通过在身体重量支撑系统上对站立的受试者进行测试，研究小腿 H 反射如何受到肢体负荷变化的影响。
本研究招募了 22 名健康受试者（10 名男性和 12 名女性）。在六种不同的肢体负荷条件下测量比目鱼肌 H 反射的大小：100%、90%、80%、70%、60%和 50%。使用单向重复测量方差分析（p<0.05）比较六种不同负荷条件下的 H/M 比值。
随着体重负荷的减少，比目鱼肌 H 反射的幅度显著降低。
本研究结果表明，当 H 反射测试作为中枢神经系统损伤患者康复干预的结果测量指标（如部分体重支撑步态训练）时，在预测试和测试条件下的体重负荷水平应保持一致。
