dc.description.abstractIn this paper, the design and testing of an ankle rehabilitation device is presented. The purpose of the research done is to provide physicians with a diagnostics tool that can quantitatively measure the severity of an injury by measuring the ankle joint's functional output. Torque and power output have been shown to be correlated with functional performance of the ankle joint. The device can measure torque and power output over the full range of motion of the ankle joint complex. Such a device has the potential to enable more accurate diagnoses and improve the efficacy of treatment and rehabilitation. The device allows rotation about the three orthogonal axes in the Cartesian plane. The rotations are linked in series to simulate ankle subjoint coupling. Cartwheel flexures with strain gages are aligned with the rotational axes and used as torque sensors. Strain gages are placed in a Wheatstone bridge circuit to mitigate environmental factors. Trials measured torque of the right ankle joint of test subjects from a standing position. Results show that the coupling of the two modes of ankle joint rotation (plantarflexion/dorsiflexion and inversion/eversion) are dependent on a subject's own development.en_US
