Safety and efficacy of add-on robotic therapy for early mobilization in intermediate neurocritical care: a pilot study.

The study was very small, with only 18 participants in the final analysis, making it underpowered to detect real differences or ensure safety. The intervention group received twice the therapy time (standard physiotherapy plus robot therapy) compared to the control group, so it is impossible to tell if the robot itself or just more therapy caused the improvement. Outcome assessors were not blinded to group allocation, which may have biased the scoring of physical function and daily living activities. There was significant attrition, with many participants dropping out or dying before the three-month follow-up, limiting the reliability of long-term results. The groups were not balanced for admission diagnosis (cranial vs. spinal), which could affect recovery trajectories. The study did not measure the practical burden on staff, such as the time required to set up and dismantle the robot, which is critical for clinical implementation.

The paper does not list specific funding sources or conflicts of interest in the provided text, though it notes the use of AI tools for grammar checking.

Do not conclude that the robot therapy itself caused the functional improvements. The robot group received both standard physiotherapy and robot therapy, while the control group received only standard physiotherapy, meaning the robot group had double the treatment time. The gains may simply reflect more therapy, not the specific benefit of the robot.
