N2 - The present study introduces a haptic-based biofeedback device that supplements the foot pressure information of a paretic foot using a wearable vibrotactile biofeedback device attached to the back. This system provides information pertaining to the hemiplegic patient's foot pressure pattern, both to the patient and the physical therapist. To verify the effect of the device, a 3-week pilot clinical trial was conducted on six patients (mean age: 56.8 ±11.4 years). Intervention was performed three times a week. After the intervention training, we observed significant improvement in stride length of the unparalyzed leg (p=0.0277). Moreover, the plantar flexion angle of the paralyzed side showed marginal improvement (p=0.0747). These results suggest that this device has the potential to improve the efficiency of push off function. However, the device did not improve ankle dorsiflexion of the paralyzed side, cadence and the walking speed. We speculate that the device, to some extent, imposed a cognitive burden, which may have interfered with the change in specific joint movements and limited its impact on comprehensive walking ability.
