I'm seeking feedback on dead arm -- the symptoms and treatment. My son's velocity dropped toward the end of the high school season. He didn't throw for about 10 days before Summer ball, but his velocity did not get better and now it has dropped even more. In his last outing he had difficulty with velocity and location. When we looked at the film of his pitching after the game, his arm path had changed, his arm action was slower, and he was needing to sink down with his legs in order to make it through his delivery to the plate. He has no pain, but he is incapable of throwing with his normal throwing motion, either when playing a field position or pitching -- he just can't bring his arm back as he typically does. He can do a work out with weights and his band work without any pain. He's tall and slender, and works out regularly. He had an x-ray taken of his shoulder, which showed no damage but that his growth plates had not closed so he's still growing. The only explanation the doctor could come up with is dead arm, so he recommended no more baseball this Summer and then strength training after taking off 10 days doing nothing. I'm wondering if part of the problem could be his body adopting to growth and compensating for a weak link somewhere other than his arm. Curious if others out there have experience with dead arm (the symptoms and causes), what they did to recuperate, how long it was before being back to full strength, etc. Thanks.
