Experimental Investigation of a Smart Insole for Gait Analysis

Gait analysis has been utlized widely to detect and monitor various lower extremity musculoskeletal and neurological disorders. Monitoring the gait events can be performed with various mechanisms, specifically including wearable smart sensors without need to visit clinics and employ highly cost equipment. The lack of clinical portable analysis tools to collect and analyze the realistc patent’s daily actvites especially in diseases on elderly and Parkinson patents is one of the major concerns conductng research in this area. The main scope of this research is to present the design, and fabricaton of a novel smart insole for experimental investgaton of human’s foot dynamic behavior during daily actvites. Performance and accuracy of the proposed system are evaluated experimentally employing statc and dynamic analysis utlizing clinical gate data. Comparatve analysis of the measured data obtained from the proposed insole prototype with the data collected through the Foot Checker indicates a moderate level of agreement, with differences of approximately ±۲۰% in both statc and dynamic analyses. These findings suggest that the compactly designed and economically fabricated prototype possesses sufficient diagnostc capabilites to serve as a useful tool in the inital stages of clinical assessment.
