Integration of music-based game approaches with wearable devices for hand neurorehabilitation: a narrative review.
Javier Urbina, Victoria E Abarca, Dante A Elias
PMID 38811987WHAT IT FOUND
Wearable devices paired with music-based games can make hand rehabilitation more engaging and measurable.
Across 16 small studies, these systems tracked finger movements and provided feedback that improved motor outcomes in stroke and spinal cord injury patients, though the evidence remains preliminary.
Key findings
01The review included 16 studies with a mean sample size of 12 participants, ranging from 1 to 30, focusing on hand neurorehabilitation using wearable devices and music-based games.
02Most included studies used passive sensor-based devices like data gloves to track movement, while fewer used active robotic devices that assist or resist motion.
03MusicGlove was the most frequently evaluated device, showing feasibility for home use and improvements in hand function measures like the Box and Blocks test in some trials.

What it does not show
The review is narrative, not systematic, meaning the selection of studies involved author interpretation rather than a strict, reproducible protocol. Sample sizes in the included studies were very small, with a mean of 12 participants and a range of 1 to 30, limiting the generalizability of the findings. Most studies were conducted in laboratory or outpatient settings, with only a few examining home-based use, so real-world adherence and effectiveness are unclear. The review did not perform a meta-analysis or statistical pooling of results, so it cannot provide an overall estimate of effect size or certainty. Many studies lacked control groups or direct comparisons to conventional therapy, making it difficult to attribute improvements specifically to the music or gamification elements.
Declared interests
The study was funded by the Annual Research Project Competition CAP-PUCP-2022. No other conflicts of interest were declared.
The easy way to misread this
Do not interpret this review as evidence that music-based wearable games are proven, superior treatments for hand function. The included studies were small, heterogeneous, and often lacked control groups, with some showing no difference from conventional therapy. The review itself is narrative, not systematic, and cannot support clinical recommendations for efficacy.
