After ulnar nerve surgery, it is feasible to perform finger splitting, flexion and extension exercises, palm-pairing exercises of the fifth finger, muscle contraction training, shoulder joint rotation training, elbow flexion and extension training. Avoid pulling the nerve for 2-3 weeks after ulnar nerve anastomosis, and use splints to restrict over-strength exercise if necessary. In order to prevent adhesion, promote the regeneration of the nerve, and enhance the muscle strength to promote the recovery of sensory function, the following training or exercise can be carried out: 1. Finger splitting and closing exercise: stretch out the palm of the hand in a fan-shaped expansion and then put the fingers together, repeat this action, 10-30 times per group. 2. Flexion and extension exercise: curl the fingers to the palm side that is flexion, if the patient can not take the initiative to flexion and extension of the healthy hand can help the affected hand to carry out this exercise, repeat 10 to 30 times per group. 3. Fifth finger to palm exercise: the thumb and little finger relative to each other, because the ulnar nerve controls the 4th to 5th finger and thumb, the fifth finger to palm exercise helps the ulnar nerve function recovery. 4. Muscle contraction training: it is beneficial to the recovery of muscle function after the nerve function is normalized. 5. Shoulder joint rotation training: the affected side of the upper limb in the healthy side of the assistance to nearly 360 degrees as the standard rotation, need to be at least 3 times a day. 6. Elbow flexion and extension training: with the healthy side of the hand as an aid, the affected side of the small arm flexion as close as possible to the shoulder joint, repeat several times.
