Principle of 3s nerve block needle

Under the guidance of a special electromyography instrument and special B-ultrasound, 3S nerve block requires the use of a 0.41mm thick and thin insulating block needle to peel the nerve from the muscle at the neuromuscular junction in the muscle that can only be seen under the microscope. At the same time, a specific frequency of current is used to stimulate the nerve junction so as to prevent the release of neurotransmitters in part of the contraction muscle. Eventually it will relieve muscle spasms.

Most children with cerebral palsy have varying degrees of spasm, which impedes their motor development and causes them to be unable to crawl, kneel and walk. Even if they can walk after rehabilitation training, their gait is often abnormal. 3S nerve block can relieve local spasm, promote motor development and improve gait.

3S nerve block technique is mature and has become one of the routine treatment methods to relieve cerebral palsy spasm in the United States. It can effectively correct the following abnormal posture.

1. Pointy feet

Pointy feet are caused by a spasm in the triceps muscle of the lower leg. If not alleviated in time, it may cause ankle contracture, leg length inequality, pelvic tilt, scoliosis and other secondary problems.

3S nerve block can relieve the spasm of the calf triceps muscle, correct the pointed foot, varus, increase the pace, improve the gait. It can also correct knee retraction caused by spasm of the calf triceps muscle.

2. Pronation

Pronation is caused by spasms of the tibial posterior muscle and can cause ankle deformity. Children with varus walk in a very ugly position with the wrong force line and cannot walk long distances.

3S nerve block can significantly improve the gait and walking ability of children with cerebral palsy after relieving tibial posterior spasm.

3. Bend your knees

An abnormal gait with a bent knee is usually caused by a hamstring spasm.

After 3S nerve block, the children with cerebral palsy can correct their kneeling posture and increase their walking height by about 10% in a few days.

4. Hip flexion

The abnormal gait with hip flexion is caused by spasms of the iliopsoas and rectus femoris muscles. The iliopsoas is made up of two muscles, the iliac and the psoas major, and the rectus femoris is part of the quadriceps.

3S nerve block can relieve the above muscles, can make the children with cerebral palsy cope buttock posture can be corrected, especially for school children, can greatly improve their self-confidence, so that they are mentally healthy development.

5. Adduction of lower limbs

Adduction of the lower limbs is caused by spasm of adductor muscles.

Adductor muscles include adductor longus, pectineus, adductor magnus, gracilis and pectineus. However, due to the deep position of the adductor short muscle and the small strength of adductor, 3S nerve block of the first four muscles is generally performed clinically. After operation, the internal rotation and scissor gait of lower limbs can be corrected. For severe cerebral palsy children, more is to facilitate nursing, improve the quality of life, prevent or delay the occurrence of hip dislocation, subluxation.

6. Bend your elbows

Elbow flexion is caused by spasms of brachioradialis, biceps brachialis and brachialis muscles. Elbow flexion causes children to take things difficult, difficult to crawl, after surgery can not only let the child's upper limb motor function can be improved, but also improve the ability to move on the bed.

7. Forearm pronation

Pronation is a common abnormal position in the forearm and is caused by spasms of the teres and pronators muscles. Forearm pronation causes many motor difficulties in children, such as difficulty eating with a spoon and inability to get food into the mouth. 3S nerve block can significantly improve the function of the child's upper limbs, making it possible to perform many movements that could not be performed before surgery.

8. Wrist flexion and knuckle flexion

Wrist flexion and knuckle flexion are often combined, mainly due to spasm of flexor carpi radialis, flexor carpi ulnar and flexor digitalis shallow. 3S nerve block can relieve the spasm of these three muscles, so that the child's hand function has been greatly improved.

9. Thumb adduction

Thumb adduction is caused by the adductor pollicis spasm in the thenar. If combined with the spasm of flexor pollicis longus and flexor pollicis brevity, it may produce the abnormal position of the thumb in the palm. It is a common abnormal position in children with cerebral palsy, which seriously affects the ability of children to grasp. The 3S nerve block can significantly improve your child's grip in a short period of time.
