Validation of Spatio-Temporal Gait Parameters Derived from X-Sensors Insoles Against OPAL Wearable Sensors

Gait analysis is essential for clinical and rehabilitative assessment, and wearable devices allow evaluations in daily-life settings. This study assessed the agreement between XSENSOR smart insoles (XSENSOR Technology, Canada) and Opal inertial sensors (APDM, USA) in measuring spatiotemporal gait parameters in 32 healthy adults walking a 10-m path. XSENSOR showed good-to-excellent agreement with Opal for speed, cadence, stride length, and cycle time. The XSENSOR system proved to be a valid and reliable tool for measuring global gait parameters.
