Vertical ground reaction force variables derived from Loadsol® insoles during overground walking are valid and reliable.

ABSTRACT: Force sensing insoles for measuring vertical ground reaction force (VGRF) have several advantages over laboratory-based force plates. Data can easily be collected in real-world environments and long duration trials with multiple steps are feasible. However, the sampling rate of insoles is lower and only vertical force is recorded. The reliability and validity of Loadsol® force sensing insoles have been evaluated for treadmill walking, but not overground walking. The purpose of the study was to determine criterion-related validity and test-retest reliability of Loadsol® compared to gold standard force plates. Twenty healthy young adults walked overground across force plates while wearing insoles for two blocks of five trials. Variables of interest were extracted from each trial and averaged
