ObjectiveTo investigate the effect of practice paradigms that varied treadmill speed during step training with body weight support in subjects with chronic hemiparesis after stroke.DesignRandomized, repeated-measures pilot study with 1- and 3-month follow-ups.SettingOutpatient locomotor laboratory.ParticipantsTwenty-four individuals with hemiparetic gait deficits whose walking speeds were at least 50% below normal.InterventionParticipants were stratified by locomotor severity based on initial walking velocity and randomly assigned to treadmill training at slow (0.5mph), fast (2.0mph), or variable (0.5, 1.0, 1.5, 2.0mph) speeds. Participants received 20 minutes of training per session for 12 sessions over 4 weeks.Main Outcome MeasureSelf-selected overground walking velocity (SSV) was assessed at the onset, middle, and end of training, and 1 and 3 months later.ResultsSSV improved in all groups compared with baseline (P<.001). All groups increased SSV in the 1-month follow-up (P<.01) and maintained these gains at the 3-month follow-up (P=.77). The greatest improvement in SSV across training occurred with fast training speeds compared with the slow and variable groups combined (P=.04). Effect size (ES) was large between fast compared with slow (ES=.75) and variable groups (ES=.73).ConclusionsTraining at speeds comparable with normal walking velocity was more effective in improving SSV than training at speeds at or below the patient's typical overground walking velocity.Copyright 2002 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation
