Systematic and proportional bias using Loadsol during stationary cycling

Abstract

Biomechanics research can have limited direct application to the clinical world because of specialized, expensive equipment that requires trained personnel to operate. The Loadsol is a wireless insole device used to measure vertical ground reaction force (GRF) and fills a need for measuring force in a clinical setting at a lower cost. The reliability of the Loadsol during running has been published (Seiberl et al., 2018), but there is no current literature regarding reliability in cycling. Cycling has been clinically prescribed during lower limb rehabilitation protocols, osteoarthritis prevention and symptom management as a result of decreased knee loading for patients (Kutzner et al., 2012). Therefore, the reliability and validity of the Loadsol during cycling when compared to 3D force sensing pedals are important and has not been addressed.
