Physical Therapy is the study and practice of helping patients restore lost motor function after an injury. Physical Therapy includes techniques like dry needling, scraping (e.g. Grastin), electrostimulation, and ultrasonics. Correctional Exercises are special exercises designed to strengthen weakened muscle groups, mobilize tight joints, and improve balance.
