摘要: Sullivan KJ, Knowlton BJ, Dobkin BH. Step training with body weight support:effect of treadmill speed and practice paradigms on poststroke locomotor recovery. Arch Phys Med Rehabil 2002;83:683-91. Objective: To investigate the effect that varied during step support in subjects chronic hemiparesis after stroke. Design: Randomized, repeated-measures pilot study 1- 3-month follow-ups. Setting: Outpatient laboratory. Participants: Twenty-four individuals hemiparetic gait deficits whose walking speeds were at least 50% below normal. Intervention: Participants stratified by se- verity based initial velocity randomly assigned to slow (0.5mph), fast (2.0mph), or vari- able (0.5, 1.0, 1.5, 2.0mph) speeds. received 20 minutes per session for 12 sessions over 4 weeks. Main Outcome Measure: Self-selected overground walk- ing (SSV) was assessed onset, middle, end training, 1 3 months later. Results: SSV improved all groups compared base- line (P.001). All increased 1-month fol- low-up (P.01) maintained these gains follow-up (P.77). The greatest improvement across occurred variable combined (P.04). Effect size (ES) large between (ES.75) (ES.73). Conclusions: Training comparable normal more effective improving than patient's typical velocity.
