Predicative factors of the effect of Body Weight Support Treadmill Training in stroke hemiparesis patients

Abstract

[Purpose] The aim of this study was to determine if gait index predicts the efficacy of weight-support treadmill training (BWSTT) in hemiplegic stroke patients. [Participants and Methods] In total, 21 patients who had sustained a hemiplegic stroke, on an average 71 days prior, and could walk independently on level ground were included in the study. BWSTT was performed under 20% of bodyweight unloading at the maximum speed possible for each participant to a perceived level of fatigue of 15 on the 20-point Borg scale. The immediate effects of BWSTT were evaluated as the change in the following variables, calculated from 5 level ground gait cycles; walking speed and rate, root mean square, coefficient of variability, auto-correlation coefficient, and single leg stance time ratio. All indices were calculated from the triaxial accelerometer attached to the waist of the participant. Linear regression was used to identify predictive variables of BWSTT effectiveness. [Results] Only single leg stance time ratio on level ground was extracted as a predictor of BWSTT effectiveness. [Conclusion] Single leg stance time ratio was a predictive factor of improved gait symmetry after BWSTT and therefore, could be used as a factor to select patients who might benefit from BWSTT as a component of stroke rehabilitation.

The Short-Term Effects of Rhythmic Vibrotactile and Auditory Biofeedback on the Gait of Individuals After Weight-Induced Asymmetry

“…Increased stance time symmetry has been associated with improved gait performance and rehabilitation outcomes in certain patient groups. [15][16][17] Secondarily, the study examined other key gait parameters including velocity, cadence, stride length, double support time, and step length symmetry associated with rhythmic stimulation.…”
