Background: Brachial plexus syndrome Injury causes chronic impairments that require long-term management. Injuries to the brachial plexus frequently result in decreased upper limb sensation and muscle strength was involved in two-wheeler versus lorry Road Traffic Accident (RTA). It results in decreased upper limb sensation and muscle strength.

Aim: The aim Is to find out the effectiveness of neuromuscular electrical stimulation along with conventional therapy in rehabilitation of post traumatic damage of brachial plexus in brachial plexus in multiple trauma patient.

Case Study: A 21-year-old man was involved in two-wheeler versus lorry Road Traffic Accident (RTA). Which leads to brachial plexus injury due to penetrating injury and multiple traumas in various parts the body. The patient received neuromuscular electrical stimulation along with conventional therapy, which includes suspension therapy, stretching and strengthening exercise along with massage therapy.

Outcome Measures: The oxford grading scale used to measure the strength of the muscle involved. The disability of arm, shoulder and hand [DASH] questionnaire assess the functional disability.

Result: The patient is now functionally independent shown by DASH Score.

Conclusion: Neuromuscular electrical stimulation along with conventional therapy is effective in rehabilitation of post traumatic damage of brachial plexus in brachial plexus in multiple trauma patient.
