Task-related circuit training improves performance of locomotor tasks in chronic stroke: a randomized, controlled pilot trial.
OBJECTIVE
To evaluate the immediate and retention effects of a 4-week training program on the performance of locomotor-related tasks in chronic stroke.


METHODS
Randomized, controlled pilot study with 2-month follow-up.


METHODS
Rehabilitation center.


METHODS
A convenience sample consisting of 12 chronic stroke subjects was used. Subjects were randomly assigned to the experimental or the control group. Three subjects withdrew from the study.


METHODS
Both experimental and control groups participated in exercise classes three times a week for 4 weeks. The exercise class for the experimental group focused on strengthening the affected lower limb and practicing functional tasks involving the lower limbs, while the control group practiced upper-limb tasks.


METHODS
Lower-limb function was evaluated by measuring walking speed and endurance, peak vertical ground reaction force through the affected foot during sit-to-stand, and the step test.


RESULTS
The experimental group demonstrated significant immediate and retained (2-month follow-up) improvement (p < or = .05) compared with the control group in walking speed and endurance, force production through the affected leg during sit-to-stand, and the number of repetitions of the step test.


CONCLUSIONS
The pilot study provides evidence for the efficacy of a task-related circuit class at improving locomotor function in chronic stroke.
