Effectiveness of robotic balance training on postural instability in patients with mild Parkinson's disease: A pilot, single blind, randomized controlled trial.

The sample size was very small (22 patients total), and the study was monocentric, meaning the findings cannot be generalized to the wider Parkinson's population. The follow-up period was short (one month), so it is unknown whether the retention of balance gains in the robotic group would last longer or if the conventional group would have caught up later. The study did not directly measure fall rates, fear of falling, or balance confidence, so the claim that improved postural stability reduces fall risk is speculative. As a pilot study, it was not powered to detect small differences in secondary outcomes, and the lack of blinding for participants and therapists could introduce bias.

The authors declared no conflicts of interest. The study was approved by the local ethics committee. The funding source is not explicitly stated in the provided text, but the device manufacturer (Movendo Technology) is named in the methods.

Do not conclude that robotic training is superior for all outcomes. The advantage was specific to retaining balance scores at follow-up; there were no significant differences between the groups in gait speed, functional mobility tests, or quality of life. Additionally, the small sample size means these findings are preliminary and require confirmation in larger trials.
