Background In post-stroke patients, the possibility of performing an active ankle dorsiflexion movement is favorable for the recovery of gait. Moreover, the fatigue due to repetitive active ankle dorsiflexion could reduce the speed gait. We assessed the change in coefficient of fatigability of active ankle dorsiflexion after a home-based self-rehabilitative procedure in post-stroke patients. Methods In a prospective open-label observational study conducted in 2 university hospitals, a home-based self-rehabilitation treatment comprising two 12-minute sessions per day (3 times per week for 3 months) was performed by 10 outpatients with post-stroke lower limb impairment. Each session consisted of three 1-minute series of repeated active ankle dorsiflexion efforts at maximal speed on the paretic side, each one followed by 3-minute bouts of triceps surae stretch. Coefficients of fatigability of dorsiflexion and 10-meter barefoot ambulation speed were evaluated at baseline and at the end of the program. Results At 3 months of follow-up, there was a decrease in the coefficients of fatigability of ankle dorsiflexion, both with knee flexed and extended (respectively from 8% to 2% and from 6% to 2%; P <.01), associated with an increase in comfortable ambulation speed (from.24 to.26 m/s; P <.05). Conclusions The reduction of coefficient of fatigability of ankle dorsiflexion, together with walking speed improvement, suggested the effectiveness of self-rehabilitation using alternated periods of self-stretch and rapid alternating efforts in the paretic lower limb after stroke.

Abstract

Background In post-stroke patients, the possibility of performing an active ankle dorsiflexion movement is favorable for the recovery of gait. Moreover, the fatigue due to repetitive active ankle dorsiflexion could reduce the speed gait. We assessed the change in coefficient of fatigability of active ankle dorsiflexion after a home-based self-rehabilitative procedure in post-stroke patients. Methods In a prospective open-label observational study conducted in 2 university hospitals, a home-based self-rehabilitation treatment comprising two 12-minute sessions per day (3 times per week for 3 months) was performed by 10 outpatients with post-stroke lower limb impairment. Each session consisted of three 1-minute series of repeated active ankle dorsiflexion efforts at maximal speed on the paretic side, each one followed by 3-minute bouts of triceps surae stretch. Coefficients of fatigability of dorsiflexion and 10-meter barefoot ambulation speed were evaluated at baseline and at the end of the program. Results At 3 months of follow-up, there was a decrease in the coefficients of fatigability of ankle dorsiflexion, both with knee flexed and extended (respectively from 8% to 2% and from 6% to 2%; P <.01), associated with an increase in comfortable ambulation speed (from.24 to.26 m/s; P <.05). Conclusions The reduction of coefficient of fatigability of ankle dorsiflexion, together with walking speed improvement, suggested the effectiveness of self-rehabilitation using alternated periods of self-stretch and rapid alternating efforts in the paretic lower limb after stroke.
