The relationship between walking speed and muscle strength for knee extension in hemiparetic stroke patients: A follow-up study.

Abstract

Walking speed and isokinetic strength of knee extension were examined in 18 hemiparetic stroke patients prior to, and 4 and 8 weeks after gait training. Although increase of the walking speed did not coincide with that of the isokinetic strength of the affected and non-affected sides, regression analysis revealed that the strength of the affected side was the primary determinant of the walking speed and the variance explained by it gradually increased with a period of the training.
