Abstract Background: Patients with stroke walk with excessive foot inversion at the affected side, which may disturb their balance and gait. Objectives: This study aimed to investigate the effects of instant biofeedback of plantar force at the medial and lateral forefoot regions on gait and plantar foot loading in patients with stroke. Methods: A total of eight patients with hemiplegic stroke, who had flexible rearfoot varus deformity at the affected side, participated in this study. A… 

mobiLLD: Exploring the Detection of Leg Length Discrepancy and Altering Gait with Mobile Smart Insoles

A mobile smart insole system designed to detect LLD by measuring gait parameters, such as Stance Time, Ground Reaction Force, and Center of Pressure, and is capable of augmenting vibrotactile feedback under the foot to compensate gait asymmetries caused by LLD.
