摘　　要：目的自制踝背屈训练器对老年女性踝关节背屈肌群进行训练,观察对下肢平衡能力的影响。方法2017年3月至4月,招募的36例老年女性志愿者采用随机数表法分为对照组(n=18)和试验组(n=18)。两组均进行自由形式的广场舞锻炼,试验组还额外应用自制踝背屈训练器进行训练。等速测试系统测量训练前后踝关节背屈肌相对峰力矩值;Footscan足底压力板测试平衡功能;测量站立提踵时间。结果训练后,试验组踝关节背屈相对峰力矩值增加(t=-2.305^-2.165,P<0.05),睁眼和闭眼状态下重心移动面积和重心位移速度减小(t=2.453~8.631,P<0.05),站立提踵时间显著延长(t=-7.909,P<0.001)。而对照组训练前后相比,上述指标无显著性差异(P>0.05)。结论应用自制踝背屈训练器可以提高老年女性踝关节背屈肌群力量,增强下肢平衡能力。Objective To explore the effect of a self-designed ankle dorsal flexion trainer (AFT) on ankle flexor muscle group of the old women and balance ability. Methods From March to April, 2017, 36 old female volunteers were divided into control group (n = 18) and experimental group (n = 18). Both groups exercised through free forms of square dance, and the experimental group exercised with AFT in addition. The relative peak torque of ankle flexor muscle group was obtained by isokinetic test. The balance test was conducted by Footscan foot bottom pressure plate, and calf-raise time was tested. Results After training, the relative peak torque of ankle flexor muscle group was stronger (t =-2.305^-2.165, P < 0.05), sway area and velocity of center of gravity under eyes open and closed decreased (t = 2.453~8.631, P < 0.05), and calf-raise time lengthened (t =-7.909, P < 0.001) in the experimental group. There was no difference in the indexes above in the control group after training (P > 0.05). Conclusion AFT can strengthen ankle flexor muscle group to improve balance function in the old women.
