Prem Center is a comprehensive physiotherapy and rehabilitation center located in Chennai, South India. The center is well equipped with skilled and efficient physiotherapists, and an orthotist/prosthetist, to render excellent quality patient care both in the outpatient as well as through home visits by physiotherapists throughout Chennai. The center functions under Dr.Sunder who is the founder and medical director. Modern treatments like therapeutic laser and lymphapress (compression therapy) are also given to patients who have specific problems like non healing ulcers and lymphedema apart from widely-used other electrotherapy modalities like short wave diathermy, interferential therapy, ultrasound, traction, and wax therapy. The services are further strengthened by a therapeutic gym for obesity management and exercises for patients with chronic neurological, or orthopedic problems. The freedom trust managed by Dr.Sunder manages a cerebral palsy clinic to provide rehab services to special children. We also provide ergonomic services to software companies and conduct international clinical trials.
