Comparing the effect of multimodal sensory stimulation program and median nerve stimulation on the level of consciousness in adults with severe head injury

Head injury is one of the most common causes of morbidity and disability among young individuals and primarily caused by motor vehicle accident which leads to altered level of consciousness, temporary or permanent physical and cognitive disabilities. The multimodal sensory stimulation therapy and median nerve stimulation helps to regain consciousness level in early phase of recovery. The present study is to compare the effectiveness of multimodal sensory stimulation program and median nerve stimulation on the level of consciousness in adults with severe head injury. 40 male and female subjects with severe head injury were selected for the study, after received inform inform consent from their relatives. All the patients were assessed and divided into two groups by simple random sampling. Group- A intervened by multimodal Sensory stimulation program and Group-B intervened by multimodal Sensory stimulation program and Group-B intervened by median nerve stimulation along with both groups received conventional physiotherapy. The Pre and Post treatment data score of GCS and CRS were recorded at the beginning and after completion of 4 weeks intervention. The data was collected and analyzed by unpaired t-test for inter group analysis between (group A and group B) and paired t-test for intra group analysis as data was normally distributed. There was a statistically significant (P<0.0001) improvement in GCS and CRS score in both the groups. After 4 weeks of intervention, there was a significant improvement in level of consciousness in both the groups. Group- A which intervened by multimodal sensory stimulation is associated with higher levels of consciousness determined by GCS and CRS when compared to group-B which intervened by median nerve stimulation in comatose head injury patients.
