ABSTRACT

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.
