Boot Camp: A Randomized Cross-Over Trial of Intensive Upper-Limb Rehabilitation After Chronic Stroke.

PMID 40629830WHAT IT FOUND
Intensive group therapy improved arm movement and daily function more than usual care.
However, only 74% of participants managed the full 90 hours. Clinicians should expect high dropout risk when prescribing this intensity to chronic stroke survivors.
Key findings
01The intensive program produced clinically meaningful improvements in arm impairment and function that usual care did not match.
02Adherence to the full 90-hour protocol fell short of the pre-set threshold, with only 74% of participants completing all scheduled therapy.
03Improvements in arm movement occurred regardless of whether the patient had measurable brain-to-muscle connections, contradicting the hypothesis that intact pathways are needed for gain.

What it does not show
The outcome assessors were not blinded, which introduces a risk of bias in how improvements were recorded. The cross-over design means participants acted as their own controls, but carry-over effects from the intensive therapy could have influenced the usual care period, potentially inflating the apparent benefit of Boot Camp. Long-term outcomes were not measured; the study only assessed effects immediately after the 5-week blocks, so it is unknown if gains persisted. Adherence to the full therapy dose was lower than expected (74%), limiting the generalizability of the '90-hour' protocol to real-world settings where fatigue or illness may prevent completion. The sample size was small (38 completers) and recruited primarily through networks and social media, which may not represent the broader stroke population.
Declared interests
The authors declared no conflicts of interest. The study was funded by the Hospital Research Foundation.
The easy way to misread this
Do not assume that all chronic stroke patients can tolerate or complete 90 hours of intensive therapy. The trial failed its own adherence threshold, with 26% of participants missing sessions due to illness or fatigue, and the long-term sustainability of the gains was not tested.
