A Novel Instrumented Outsole for Real-Time Foot Kinematic Measurements: Validation Across Different Speeds and Simulated Foot Landing

Neuromuscular disorders, especially in Cerebral Palsy patients, lead to foot deformities and affect biomechanics leading compromised gait. Thus, the kinematic measurement is of particular interest understand characterize walking pattern. The present work aims develop a wearable instrument measure kinematics such as foot-to-ground angle three-dimensional planes clearance, i.e., toe heel clearances. A template-based outsole was developed that incorporated optical distance sensors located anatomically on magnetometer kinematics. system validated against reference marker-based motion capture from Noraxon, USA. data eight able-bodied participants were acquired simultaneously both systems (developed system) at three different speeds. center pressure (CoP) based feedback presented shift sagittal CoP anteriorly, posteriorly medially simulate pattern patients with neuromuscular disorder landing strategies. It found more than or equal 96.48% values differences between limit agreement, Pearson’s correlation coefficient 0.76 root mean square error less 3.45 degrees. Furthermore, wireless wristband for real-time vibrotactile feedback. Since instrumented wearable, low-cost, easy use implement, it has great potential measurements.
