PMID 40322580WHAT IT FOUND
A woman with severe stroke-related paralysis walked faster and took fewer steps when body weight-supported overground training was added to standard therapy.
Her walking speed rose to 0.58 m/s during the training phase, dropping when it stopped and rising again when it resumed.
Key findings
01Walking speed peaked at 0.58 m/s during the first body weight-supported training phase, compared to 0.37 m/s in the preceding standard therapy phase.
02The patient's step count to complete a 10-meter walk dropped to 15 steps during the first training phase, down from 32 steps in the preceding standard phase.
03Walking speed declined to 0.45 m/s when the body weight-supported training was withdrawn and replaced with standard therapy, then improved to 0.50 m/s when training resumed.

What it does not show
This is a single-case report, so the results cannot be generalized to other patients with severe stroke. The patient received standard physiotherapy in all phases, so it is impossible to separate the effect of BWSOT from the natural recovery or the concurrent standard care. The transition from a knee-ankle-foot orthosis to an ankle-foot orthosis occurred during the second BWSOT phase, confounding the interpretation of improvements in that period. The study did not use a control group, and the therapist administering the intervention was not blinded to the study design, though they were blinded to the specific objectives.
Declared interests
The study received no funding, and the authors declare no conflicts of interest.
The easy way to misread this
Do not conclude that BWSOT alone caused the functional recovery. The patient improved in all phases, including when BWSOT was withdrawn, and the transition to a less restrictive orthosis occurred concurrently with the second training phase, making it difficult to attribute gains specifically to the suspension system.
