Abstract

Using lower extremity exoskeletons in the healthcare field like for rehabilitation is a substantial application. Lower limb exoskeletons can help in performing specific functions like gait assistance, and physical therapy support for patients who are lost their ability to walk again. The ground reaction force characteristics during human walking can be an important descriptor of gait disorders. The purpose of this study is to reveal the effect of the designed lower limb exoskeleton on the patient with right lower limb weakness based on the investigation of the ground reaction force. Results show that dynamic asymmetry practically disappears in the vertical GRF between the left and right legs during walking using the exoskeleton. The symmetry between the left and right limbs when walking using the exoskeleton for the maximum vertical GRF (first peak) is 98.9%, the minimum vertical GRF (the valley) is 99%, and the maximum vertical GRF (second peak) is 97.48%.
