With no controls you can't tell if this is the placebo effect, the Hawthorne effect, or the training. Bad research.

ABSTRACT. Sullivan KJ, Knowlton BJ, Dobkin BH. Step training with body weight support: effect of treadmill speed and practice paradigms on post stroke locomotor recovery. Arch Phys Med Rehabil 2002;83:683-91.
Objective:
To investigate the effect of practice paradigms that varied treadmill speed during step training with bodyweight support in subjects with chronic hemiparesis after stroke.
Design:
Randomized, repeated-measures pilot study with 1-and 3-month follow-ups.
Setting:
Outpatient locomotor laboratory.
Participants:
Twenty-four individuals with hemiparetic gait deficits whose walking speeds were at least 50% below normal.
Intervention:
Participants were stratified by locomotor se-verity 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 20minutes of training per session for 12 sessions over 4 weeks.
Main Outcome Measure:
Self-selected overground walking velocity (SSV) was assessed at the onset, middle, and end of training, and 1 and 3 months later.
Results:
SSV improved in all groups compared with base-line (P<.001). All groups increased SSV in the 1-month follow-up (P<.01) and maintained these gains at the 3-monthfollow-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).
Conclusions:
Training at speeds comparable with normal walking velocity was more effective in improving SSV than training at speeds at or below the patient’s typical over ground walking velocity.
