FEATURES The Biomechanics Gait Analysis Laboratory offers a variety of useful features for analyzing a Subject’s gait. Such features include: • Innovative force sensitive resistor (FSR) insoles • Wireless transmission of total gait cycle data. • Compact and portable design • Original National Instruments LabVIEW computer programs • Capable of calculating the following gait parameters: Footswitch Insoles ‣ total gait cycle duration ‣ stance phase duration ‣ swing phase duration ‣ time of toe contact ‣ time of 1 st metatarsal contact ‣ time of 5 th metatarsal contact ‣ time of heel contact ‣ total gait cycle length ‣ stance phase length ‣ swing phase length ‣ % of time on toe during stance phase ‣ % of time on 1 st metatarsal during stance phase ‣ % of time on 5 th metatarsal during stance phase ‣ % of time on heel during stance phase ‣ cadence ‣ total gait cycle velocity ‣ stance phase velocity ‣ swing phase velocity FSR Insoles ‣ weight distribution on toe during stance phase ‣ weight distribution on heel during stance phase Page 4
