The group's principal activity is to design, manufacture and market foot and gait-related biomechanical products. The group applies scientific and quantitative methods for the diagnosis and treatment of foot and gait-related problems. The core product of the group is a custom-made, prescription orthotic device known as foot orthoses. They are placed inside the patients' shoes to correct the abnormalities in their gait and relieve symptoms associated with foot or postural malalignment. The other products of the group include ppt products and pediatric counter rotation system. Ppt is a medical grade soft tissue cushioning material. It provides protection against forces of pressure, shock and shear. In 2003, the group acquired all the capital stock of bi-op laboratories inc.
