Suprascapular neuropathy (SSN) is an injury found in sports with overhead actions, such as volleyball. A study of 66 top-level German volleyball players revealed a 32% prevalence of this injury.65 Suprascapular neuropathy is believed to occur as a result of the "floater" serve.66 This is when the player stops the overhand follow-through immediately after striking the ball, which results in a forceful eccentric contraction of the infraspinatus muscle to decelerate the arm. This contraction is believed to cause traction from the myoneural junction to the spinoglenoid notch and consequent compression of the nerve. The symptom can be a weakness of the musculature without pain.
Dry needling acupuncture is very effective in healing suprascapular neuropathy. As usual, the location of the tender areas should be carefully identified and treated twice a week. Before any shoulder weakness is experienced, the injury can be effectively prevented by de-stressing treatment once a week to reduce chronic stress of the girdle musculature and the entire kinetic chain.
