PMID 41857613WHAT IT FOUND
All four exoskeleton training groups improved walking.
Only the high-speed, long-duration group reached clinically meaningful gains in speed and endurance. Speed alone helped gait speed. Duration alone helped endurance. Combining both was superior to either alone.
Key findings
01Only the high-speed, long-duration group reached the minimal clinically important difference for 10-meter walk speed (0.18 m/s vs threshold 0.16 m/s) and 6-minute walk distance (21.58 m vs threshold 20 m).
02High-speed training alone significantly improved gait speed and reduced spatial asymmetry compared with routine training, but did not match the combined group for speed gains.
03Long-duration training alone significantly improved 6-minute walk distance and gait symmetry compared with routine training, but did not reach the endurance MCID threshold.

What it does not show
The study lasted only three weeks with no long-term follow-up, so it is unknown if these gains persist. It was a single-centre trial with a small sample, limiting generalisability to community or chronic-stage patients. Therapists and participants could not be blinded, which may have influenced effort or interaction. The device speed was capped at 0.5 m/s, so benefits of faster training were not tested. Some participants had incomplete acute-care records, limiting analysis of early stroke factors.

The easy way to misread this
Do not assume that routine exoskeleton training alone is sufficient for clinically meaningful recovery. While all groups improved statistically, only the high-speed, long-duration group reached the minimal clinically important difference thresholds for walking speed and endurance.
