Impact of Training on Gait and Strength in Stroke Survivors
Gait Performance and Lower-limb Muscle Strength Improved in Both Upper-limb and Lower-limb Isokinetic Training Programs in Individuals With Chronic Stroke
Background: A discrepancy between strength gain and gait changes following various training programs aimed at improving gait function after stroke has been noted. A mismatch between the training program and gait parameters could explain this finding.
Objective: To evaluate the impact of an isokinetic-strengthening program, matching the requirements of the affected lower-limb muscle groups involved in the energy generation of gait, to a control intervention, on gait performance and muscle strength.
Hypothesis: The isokinetic training program of the affected lower-limb muscles would produce greater changes in gait performance and strength than a control intervention not aiming at training these muscle groups.
Design: Single-blinded randomized controlled trial.
Participants: A convenient sample of 30 individuals with chronic hemiparesis.
Interventions: Participants were randomly assigned into two groups (n=15), each training three times/week for six weeks. The experimental group trained the affected plantarflexors, hip flexors and extensors concentrically, while the control group trained the affected upper-limb muscles.
Main outcome measures: Baseline values and post-training values, taken at the end of the training program, of maximal voluntary concentric strength, gait speed and peak positive power.
