Effect of the use of a body weight-supported walker on gait parameters in hemiplegic stroke patients

[Purpose] This study investigated gait parameter changes in hemiplegic stroke patients who walked with a body weight-supported (BWS) walker and evaluated the usefulness of using the BWS walker in a walking exercise. [Participants and Methods] Nineteen hemiplegic stroke patients hospitalized in a convalescent rehabilitation ward were enrolled in the study. Trunk acceleration was used to evaluate walking with and without a BWS walker. Gait speed, cadence, stride length, step time symmetry, stride time variability, and stride time regularity were calculated from the accelerometer waveform. [Results] Hemiplegic stroke patients had a faster gait speed, walked more symmetrically, and had less variation in their gait cycle when using the BWS walker than when not using it. [Conclusion] Using a BWS walker may help hemiplegic stroke patients learn to walk more efficiently in terms of their gait speed.
