To investigate the methodology using a manual ankle joint resistive torque measurement device to evaluate the contribution of the neural component of ankle joint resistive torque in patients with stroke.
Within-subject comparison to compare the ankle joint resistive torque between fast and slow stretching conditions.
Ten patients with stroke participated in this study. The incremental ratio of ankle joint resistive torque at the ankle angular position of 5degrees dorsiflexion under the fast stretching condition in comparison to the slow one was calculated in each patient.
A significant increase (p<0.01) in the ankle joint resistive torque was demonstrated under the fast stretching condition in comparison to the slow one in all patients and the mean ankle joint resistive torque was 4.6 (SD=1.7) Nm under the slow stretching condition, while it was 8.4 (SD=4.1) Nm under the fast stretching condition at the ankle angular position of 5 degrees dorsiflexion. The incremental ratio ranged from 9.4-139.3% among the patients.
The results of this study demonstrated the potential advantage of the device to evaluate the contribution of the neural component of ankle joint resistive torque.
研究使用手动踝关节阻力扭矩测量装置评估中风患者踝关节阻力扭矩神经成分贡献的方法。
受试者内比较，以比较快速和缓慢拉伸条件下的踝关节阻力扭矩。
10名中风患者参与本研究。计算每位患者在快速拉伸条件下与缓慢拉伸条件下相比，踝关节背屈5度时踝关节阻力扭矩的增加率。
与缓慢拉伸条件相比，所有患者在快速拉伸条件下踝关节阻力扭矩均显著增加（p<0.01），在踝关节背屈5度时，缓慢拉伸条件下平均踝关节阻力扭矩为4.6（标准差=1.7）牛米，而快速拉伸条件下为8.4（标准差=4.1）牛米。患者之间的增加率在9.4%-139.3%之间。
本研究结果证明了该装置在评估踝关节阻力扭矩神经成分贡献方面的潜在优势。
