Effects of gait training using trunk IMU-Vibrotactile feedback on gait kinematic of Through Knee amputee: primarily results

Abstract The use of wearable sensors integrated with vibrotactile feedback enhances patient's awareness and control of their movements during gait training. Monitoring trunk angle during gait training can lead to improve gait patterns and reduce risk of falls. This paper presents a case study of a female participant with through knee amputation that underwent on gait training using a developed system. The system consists of a single IMU (inertial measurement unit) attached to her trunk and integrated with vibrotactile feedback. Before and after training session, Gait analysis was done, then gait symmetry index, time-distance parameters, and kinematics of lower limb and trunk were measured. The results show improvements after training in time-distance parameters and symmetry index. In addition to reducing gait deviations (lateral trunk bending and vaulting). Further research and larger studies are warranted to validate these findings and explore the full potential of this innovative technology in enhancing different levels of amputee rehabilitation.
