ABSTRACT
Objective:To assess the agreement between measurements of spatiotemporal gait characteristics made with Gaitboter and Noraxon gait analysis systems. Methods:From February to April, 2019, 35 healthy adults were recruited to participate in gait analysis using Gaitboter and Noraxon gait analysis apparatuses, respectively. Stance phase, swing phase, stride length, cadence, velocity and toe out were recorded and computed. Intraclass correlation coefficients (ICC) and Bland-Altman plots were used to evaluate the agreement between the two gait analysis systems. Results:There was a good reliability in spatiotemporal gait characteristics between two gait analysis systems (ICC 0.691 to 0.835). Bland-Altman plots also showed good agreement. Conclusion:The measurements of temporal and spatial parameters with Gaitboter and Noraxon gait analysis systems yield acceptable agreement, and further study needs to be conducted on the validity of the Gaitboter gait analysis system.
ABSTRACT
This article reviewed the changes of ankle muscle strength after lower limb joint injuries and the isokinetic test mode which could reflect this characteristic better. The varus plantarflexion strength decreased significantly after plantarflexion injury of ankle joint. The dorsiflexor strength of ankle joint could not reach the level of the healthy side for a long time after anterior cruciate ligament rupture and Achilles tendon injury. Ankle isokinetic muscle test included testing direction, muscle contraction form and testing speed. It is meaningful to test varus/valgus and plantar/dorsal flexion in ankle joint sprain and functional ankle instability; however, the muscle contraction form and testing speed have little effect on the result.
