In today’s healthcare market objective measures that quantify a client’s physical impairments accurately are essential. Impairments in muscle strength are significantly associated with musculoskeletal dysfunction and functional limitation. Strength impairments are common in aging, osteoarthritis (OA), and musculoskeletal injury leading to increased risk of falls, pain, and decreased function all contributing to increases in healthcare expenditures. The current standard of care for strength assessment in rehabilitation is unreliable and invalid, while in the fitness industry strength assessment methods pose a concern of safety in populations other than athletes. This proposal, outlines the issues with the current standard of care (SOC), to whom and why our invention is important, limitations of the current technology and why our strength testing invention has the ability to move clinical testing forward, change professional standards and revolutionize the market both in the rehabilitation and fitness industry.
