Orthopedic and Sports
Therapy Institute
Thank you for visiting the website of the Orthopedic and Sports Therapy Institute (OSTI). OSTI was founded in 1999 with Belvidere Physical Therapy. The openings of Marengo Physical Therapy, McHenry County Physical Therapy, Ogle County Physical Therapy, Poplar Grove Physical Therapy Roscoe Physical Therapy and Sauk Valley Phyical Therapy followed as the need arose in surrounding communities.
We realize when you choose your physical therapy provider you expect exceptional, cutting edge care. Each of our clinics focus on taking that “extra step” with our patients through the care of qualified, experienced clinicians to better serve your physical therapy needs. Our clinics offer a variety of services specializing in orthopedic, sports, and industrial rehabilitation.


Belvidere Physical Therapy is pleased to announce the expansion of its Women’s Health physical therapy program, Focus on Women. Our program, designed by women for women, focuses on pregnancy and post partum physical therapy care for women during all stages of their pregnancy and beyond.
