Can understanding the mechanics of the throwing motion help to understand why it may cause shoulder pain, the symptoms of a shoulder problem, the diagnosis, and the treatment options available? Throwing a Ball and Shoulder Pain The throwing motion is a complex shoulder movement that requires the mechanics of muscles, tendons, joints, ligaments, and bones. They all must move in a synchronized and stable pattern to move the shoulder joint. When these mechanics are interrupted or altered, inflammation can result in pain symptoms. ( Wardell M., Creighton D., & Kovalcik C., 2022 ) Throwing Motion Distinct phases characterize the throwing motion: The wind up Cocking Acceleration Follow-through Deceleration The rotator cuff and shoulder muscles sequentially guide the movements for effective throwing mechanics. ( Wardell M., Creighton D., & Kovalcik C., 2022 ) The labrum stabilizes the ball in the socket of the shoulder. The shoulder blade rotation coordinates with the arm to ens...
Should individuals experiencing nerve pain or various sensations get a nerve conduction velocity study to examine nerve health and function? Nerve Conduction Velocity A nerve conduction velocity (NCV) is a noninvasive test that measures the speed and strength of nerve stimulation using electrical probes placed on the skin. It's used to diagnose nerve damage or disease, often alongside an EMG (electromyogram) to differentiate between nerve and muscle problems. It can also evaluate sensory issues, pain, and weakness of the extremities. This test involves safe electrical shocks that can be slightly uncomfortable but not painful. Nerve conduction velocity (NCV) measures the speed at which electrical impulses travel along a nerve fiber, which measures how quickly electrical signals travel through a nerve. This information indicates nerve health and function. Electromyography (EMG) is a nerve test that involves placing tiny needles into the muscles. A slower NCV can indicate nerve...
