Figure 2. Insole-based biomechanical analysis revealed a lack of push-off in the ipsilateral limb and subsequent increased first ground reaction force in the contralateral limb
The sensor-mounted insole system estimates the center of pressure (COP) and vertical ground reaction force (GRF) during level walking (A ). The COP analysis in the patient revealed reduced excursion in the left (ipsilateral) limb, which was derived from a lack of push-off motion by the forefoot (B ). The COP in healthy adults is provided as a reference. The patient displayed reduced first and second peak GRF in the ipsilateral limb and increased first peak GRF compared to healthy adults (C ).
