About Us

Total sports rehabilitative care from an experienced, highly trained team of physical therapy specialists

At Cedar Valley Physical Therapy, our physical therapists evaluate and treat patients with physical dysfunctions from an injury or post-surgical state relating to sports and non-sports activity to help them restore and facilitate return to normal function and movement. Our team of licensed physical therapists, certified athletic trainers, and physical therapist assistants will evaluate and work with you to identify specific goals and will individualize your treatment plan so you can experience personalized care.

These treatment options can include supervised therapeutic exercise, manual therapy, neuromuscular re-education, gait training, patient education, isokinetic testing, and modalities to decrease pain and inflammation. With a sports medicine clinic at the University of Northern Iowa in Cedar Falls and three additional locations throughout the Cedar Valley, we offer the latest therapeutic technology and numerous services to help you return to the activities you love.
