During the process of nerve microsurgical reconstruction, 30 minutes of electrical stimulation is applied to the distal end of the damaged nerve to assess its potential benefits for nerve regeneration, functional recovery, slowing down the degeneration at the neuromuscular junction, and preventing muscle atrophy.

NCV/EMG(CMAP,latency)
The electromyography (EMG) is a diagnostic method used to assess muscle and nerve function, primarily to detect muscle activity and nerve conduction velocity, in order to monitor the recovery of neuromuscular function after surgery. During the EMG examination, the examiner uses electrodes attached to the palm to measure and record the electrophysiological signals of the muscles for further analysis. Through this method, doctors can evaluate the electrophysiological activity of the muscles to assess the reinnervation of distal muscles by the damaged nerves.
Time frame: The third month after surgery.
DASH questionnaire
The DASH questionnaire (Disabilities of the Arm, Shoulder, and Hand) is a tool used to assess a patient's upper extremity function and symptoms. It helps in evaluating the impact of musculoskeletal disorders on daily activities and quality of life.
Time frame: The first, third, and sixth months after surgery.
Muscle power
Muscle power refers to the ability of a muscle or group of muscles to exert force quickly. It is a combination of strength and speed, and is often measured in activities that require explosive movements, such as sprinting, jumping, or lifting weights. Muscle power is important for athletic performance and functional movement in daily activities.
Time frame: The third and sixth months after surgery.
Purdue Pegboard test
The Purdue Pegboard test is a standardized assessment used to measure manual dexterity and fine motor skills. It involves placing pegs into holes on a board as quickly and accurately as possible, using one hand at a time and then both hands. The test is commonly used in occupational therapy, rehabilitation, and research to evaluate hand function and coordination.
Time frame: The third and sixth months after surgery.

NCV/EMG(CMAP,latency)
Electromyography (EMG) is a diagnostic method used to assess muscle and nerve function, primarily for detecting muscle activity and nerve conduction velocity to monitor the recovery of neuromuscular function post-surgery. During an EMG examination, the examiner attaches electrodes to the palm to measure and record the electrophysiological signals of the muscles for further analysis. This allows physicians to evaluate the electrophysiological activity of the muscles and assess the reinnervation of distal muscles by the damaged nerves.
Time frame: The sixth month after surgery.
