简要总结
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.

结局指标
主要结局
change in gait speed
时间窗: gait speed was assessed at baseline and at the completion of the 6-week training (i.e. week #7)
change in gait speed, in meter/second, was assessed as the difference between the baseline and week #7 values.
change in peak positive power
时间窗: peak positive power was assessed at baseline and at the completion of the 6-week training (i.e. week #7)
peak positive power was evaluated at the affected plantarflexors, hip flexors and hip extensors. Also, change in peak positive power, in weight/kilogram, was assessed as the difference between the baseline and week #7 values.
次要结局
- change in maximal voluntary concentric strength(maximal voluntary concentric strength was assessed at baseline and at the completion of the 6-week training (i.e. week #7))
