The role of muscles in wrist and other repetitive stress injuries
Muscles originate on a fixed bone in our body, cross over a joint, and insert onto a moving bone. It is important to understand that all muscles move from the insertion point going toward the origination point. It is because of the placement of the muscles that we can move, but when a muscle is in spasm, or is contracted we cannot move the joint it affects without pain.
Muscle Spasms & Pain
Visualize muscle fibers running down your arm from the elbow to the wrist. We will focus on the top of the arm, muscles collectively called "The Extensors". When the muscles are contracted you feel tight ropes traveling down your arm, each muscle distinct from the other.
If you press deeply and slide on the muscle, from the elbow down, you will often feel "bumps" that are painful. The "bumps" are muscle spasms, the "tight ropes" are the contracted (shortened) muscle fibers.
A spasm involves only some of the fibers of the entire muscle, a contraction is when the entire muscle shortens. The muscle is still attached at the two points, but since it is too short to comfortably make the distance, you are feeling a strong pull on the insertion point.
Both a spasm, and a contraction, causes pain at the joint. Often conditions diagnosed as Fibromyalgia and Arthritis are actually tight muscles pulling on the joint.
The Julstro Technique will teach you how to relieve the pain by lengthening and stretching the muscle.
Repetitive use of a muscle causes a buildup of lactic acid, which contributes to pain and spasm of the muscle. Therefore, it is important to learn how to flush lactic acid from muscles.
The Julstro Technique will teach you how to flush out lactic acid and allow fresh blood to flow into your muscles.
As you are doing the treatments you will be releasing the lactic acid by pressing down on the fibers which will push it out, and then as you release the pressure the fresh blood will fill the void, nourishing the muscle fibers.
