Background: Traumatic brain injury is one of the devastating clinical conditions, leading to loss of consciousness and arousal at some point of time after injury. The median nerve serves as the peripheral gateway for accessing the central nervous system among persons with coma. Aim: The study aims to evaluate the effectiveness of the right median nerve electrical stimulation on functional status in participants with traumatic brain injury. Methods: A quasi-experimental study was done on 30 traumatic brain injury participants. Participants were recruited after obtaining an informed consent form from the participant__ampersandsignrsquo;s caregiver. Ranchos Los Amigos Scale was used as a screening tool for the inclusion of participants. The pre-test measurement of functional status was obtained through the Disability rating scale. Right median nerve electrical stimulation was given over the right hand for four weeks. At the end of study duration, Post-test measurements were taken and data were tabulated and analyzed statistically by using Wilcoxon signed-rank test. Results: It was observed that there was a significant improvement in functional status (P__ampersandsignlt;0.001) in participants with traumatic brain injury. Conclusion: Right median nerve electrical stimulation is a safe, inexpensive, and noninvasive technique that has a beneficial effect on improving functional status among brain injury participants.
