Electromyography‚ also known as EMG‚ is an electro diagnostic medicine technique for evaluating and recording the electrical activity produced by skeletal muscles. Electromyography is performed using an instrument called an electromyograph. An electromyograph detects the electrical potential generated by muscle cells when these cells are electrically or neurologically activated. The signals can be analyzed to detect medical abnormalities‚ activation level‚ or recruitment order‚ or to analyze the

Stability of the scapulothoracic joint depends on the coordination of the surrounding musculature. Dysfunction or weakness in the scapular musculature alters mechanics and positioning of the scapula and may lead to alterations in the biomechanics of the GH joint. An unstable scapular base may affect the center of rotation of the GH joint and alter the length-tension relationship of the muscles involved in humeral movement. There is a possibility that any inefficiency in scapular stabilization could cause

vitality can be exceptionally valuable when additionally talking about weakness. A basic thought to recollect is that muscle compression is because of a particle called ATP (adenosine triphosphate). ATP must be available for muscles to contract. There are three frameworks of energy that create ATP: Phosphocreatine system‚ the glycolytic system‚ or the oxidative system. On the off chance that exhausted‚ it must be renewed if additional muscle withdrawal is to proceed. Since we are talking about ATP Pathways
