One major element to knowing when to return to sport, life activities or work is knowing ratios of agonist and antagonist muscles as well as right to left symmetrical function. Isokinetic testing is muscle movement isolation. By isolating the muscle groups we can measure, evaluate, and increase the strength of muscles, range of motion of joints and the correlation they play with your injury. The machine’s main function is to improve your function. All of the different factors that can effect your movement can be measured and replicated with this machine. Your return to daily activities cannot be taken lightly and should have strong measurements to guide that process.
