Virtual reality-assisted rehabilitation for postoperative C5 palsy: a pilot exploratory randomized controlled trial.
Kyung-Soo Suk, Jinyoung Park, Taeyeon Choi and 7 others
PMID 40804401WHAT IT FOUND
Adding VR to standard care did not improve primary muscle strength measures in this small pilot.
The VR group showed some better pain and quality-of-life scores, but they also received an extra hour of therapy daily, so the VR itself may not be the cause.
Key findings
01The primary outcome, maximal voluntary isometric contraction of the deltoid, showed no significant difference between the VR and control groups at 24 weeks.
02The VR group reported significantly less arm pain and better quality of life than the control group at 12 and 24 weeks, respectively.
03The VR group received one additional hour of guided rehabilitation per session compared to the control group, which may explain the observed benefits regardless of the VR technology.

What it does not show
The study was extremely small, with only 10 participants analyzed (4 in the VR group, 6 in the control group). The VR group received significantly more total therapy time (one extra hour per day) than the control group, making it impossible to separate the effect of VR from the effect of increased exercise dose. Baseline imbalances existed: the VR group was younger and had fewer comorbidities (no diabetes) than the control group, which could independently lead to better recovery. The study was not powered to detect differences, and p-values were interpreted with caution due to the small sample size. All participants were male, limiting generalizability to female patients.
Declared interests
The paper does not explicitly state a conflict of interest declaration in the provided text, but it is a single-center study with no external funding mentioned.
The easy way to misread this
Do not conclude that VR technology is superior to standard care for C5 palsy recovery. The VR group received an additional hour of guided rehabilitation per day compared to the control group, so the benefits in pain and quality of life may be due to increased therapy time rather than the VR interface itself.
