Technology-assisted stroke rehabilitation in Mexico: a pilot randomized trial comparing traditional therapy to circuit training in a Robot/technology-assisted therapy gym.

PMID 27634471WHAT IT FOUND
Robot gym therapy matched traditional therapy for arm function but improved leg movement scores more.
The groups differed sharply in age, with the robot group much younger. The robot gym allowed one therapist to supervise six patients at once, potentially doubling daily treatment volume.
Key findings
01For lower limb motor impairment, the robot gym group improved significantly more than the control group, while upper limb function improved similarly in both.
02The robot gym group was significantly younger than the control group, which may explain the difference in walking capacity outcomes.
03The robot gym design allowed one therapist to supervise six patients simultaneously, increasing the number of patients treated per year compared to time-matched traditional therapy.

What it does not show
The study was severely underpowered with only 20 participants analyzed. There was a large baseline age difference between groups (44 vs 64 years), which confounds the lower limb and walking outcomes. The control group received 2 hours of therapy per session, which is four times the typical 30-minute standard of care at this center, making the comparison unrealistic for routine practice. The intervention was a complex mix of six different devices and therapies, so it is impossible to attribute effects to any specific component. Results are short-term only; long-term retention of gains was not assessed.

The easy way to misread this
Do not conclude that robot therapy is superior for walking or lower limb function. The robot group was significantly younger than the control group, and the authors explicitly attribute the difference in walking capacity to this age gap rather than the technology.
