A mechanical jig for measuring ankle supination and pronation torque in vitro and in vivo
journal contribution
posted on 2016-07-15, 11:06 authored by Daniel FongDaniel Fong, Mandy Man-Ling Chung, Yue-Yan Chan, Kai-Ming ChanThis study presents the design of a mechanical jig for evaluating the ankle joint torque on both cadaver and human ankles. Previous study showed that ankle sprain motion was a combination of plantarflexion and inversion. The device allows measurement of ankle supination and pronation torque with one simple axis in a single step motion. More importantly, the ankle orientation allows rotation starting from an anatomical position. Six cadaveric specimens and six human subjects were tested with simulated and voluntary rotation respectively. The presented mechanical jig makes possible the determination of supination torque for studying ankle sprain injury and the estimation of pronation torque for examining peroneal muscle response.
Funding
The study was financially supported by the Innovation Technology Fund from the Innovation and Technology Commission, Hong Kong Special Administrative Region Government, project number: ITS/013/07. The authors acknowledge Mr Wai-Man Ng of the Mechanical Services Unit of The Chinese University of Hong Kong to provide technical assistance in the fabrication process.
