| 目的 探讨脑卒中偏瘫患者膝关节屈肌/伸肌峰值力矩比值（H/Q值）与平衡及步行功能的相关性。 方法 入组符合标准的脑卒中偏瘫患者30例，采用等速肌力测试评估患者在不同角速度［60(°)/s和120(°)/s］下的膝关节H/Q值，采用Pro-Kin平衡测试系统评估患者运动控制能力，采用Berg平衡量表（BBS）、起立-行走计时测试（TUGT）和10 m步行测试（10MWT）评估患者平衡和步行功能，并将患侧膝关节H/Q值与BBS、TUGT、10MWT、稳定极限和偏移指数进行相关性分析。 结果 ①在60(°)/s和120(°)/s角速度下，脑卒中偏瘫患者的患侧膝关节H/Q值［（41.00±15.38）%和（40.62±17.87）%］均小于健侧［（57.18±12.52）%和（62.00±18.21）%］，且差异均有统计学意义（P<0.001）。②脑卒中偏瘫患者患侧膝关节在60(°)/s和120(°)/s角速度下的H/Q值与BBS和稳定极限均呈正相关（P<0.01），与TUGT、10MWT和偏移指数均呈负相关（P<0.05）。 结论 脑卒中偏瘫患者患侧膝关节H/Q值与其平衡及步行功能具有相关性， H/Q值可能是评估脑卒中患者运动功能的临床评测指标之一。 |

| Objective To seek any correlation of the ratio of knee flexor to knee extensor peak torque (H/Q) with the balance and walking ability of hemiplegic stroke survivors. Methods Thirty stroke survivors with hemiplegia had the H/Q value of their knees measured at angular velocities of 60°/sec and 120°/sec using an isokinetic muscle strength test. Their motor control ability was assessed using the Pro-Kin balance test system, while their balance and walking were assessed using the Berg balance scale (BBS), the stand-to-walk timing test (TUGT) and the 10m walk test (10MWT). Any correlation was sought between the H/Q value of the affected knee, the test results, stability limits and offset index. Results The average H/Q values of the affected knee joint at 60°/sec and 120°/sec were significantly lower than those of healthy joints. They were positively correlated with BBS scores and stability limits, and negatively correlated with TUGT and 10MWT times and with the offset indices. Conclusion The H/Q value of the affected knee of a stroke survivor with hemiplegia predicts balance and walking ability. It may be a useful clinical indicator for evaluating their motor functioning. |
