Our Therapy Team
Ohio Sports & Spine Institute has developed an expert physical therapy team utilizing the approach to treating neuromusculoskeletal injury and disease by integrating the usually separate practices of physical therapy with physical medicine and rehabilitation, occupational medicine, sports medicine, evidence-based chiropractic care, acupuncture, speech therapy, and massage therapy.
This unique practice model allows for on-site physical therapy and rehabilitation directed by a physician and supervised by a rehabilitation staff of physical therapists, physical therapist assistants and massage therapists.
Our Team Working for A Common Goal
Patients may see one of our expert physicians at our practice first or be directly referred to one of our physical therapists by their family physician, orthopedic, or other specialist. The physicians and therapists work side by side with the patient, who becomes an active team participant with the goal of quickly returning to optimum levels of function and physical performance.
