My 14U DD has been experiencing lower back pain for approx the last half of this season with eventually being taken out of the pitching rotation. After seeing a specialist, the CT scan revealed SPONDYLOLYSIS in the L5 and L7 vertebrae. The doctor said it is a stress fracture of the bone caused by overtraining activities such as diving, football and gymnastics. My DD has been taught resistance pitching. She currently is scheduled to go to physical therapy to strenghen her back muscles and her pitching days might be over. I appreciate any advise from parents/coaches who have seen this before and am wondering if the pitching style has cause this problem.
