As an orthopedic physical therapist, I commonly see teres major and minor strains in athletes, especially those participating in overhead sports like swimming, tennis, and baseball. These muscles stabilize the scapula during shoulder movements, so overuse or direct blows often cause injury. For diagnosis, I use orthopedic testing and imaging like ultrasound to check muscle and tendon damage. Initial treatment includes rest, ice, and anti-inflammatories. Physical therapy focuses on range-of-motion and strengthening exercises. For severe tears, surgeons may repair tendons or reattach muscles. Post-op rehab takes 3-6 months; therapy helps regain strength and full function. One swimmer returned too quickly after a teres minor strain, re-tearing it and needing surgery. With diligent rehab, he returned to competition in 9 months. A tennis player suffered a blow to the teres major; diagnosis showed a partial tear. With proper rest and therapy, he was back on court in 8 weeks. Early diagnosis and proper rest and rehab are key for these athletes. While recovery takes time, most return to full actovity.
