Trial Outcomes & Findings for Custom Molded Foot Orthoses Effect on Foot Kinematics and Lower Extremity Electromyography During Walking and Running. (NCT NCT02143947)

NCT ID: NCT02143947

Last Updated: 2015-05-18

Results Overview

The rearfoot eversion motion during the stance phase of walking with the subject wearing a sandal and their assigned orthotic (Full Contact or Maximal Arch Subtalar Stabilization) was recorded 5 weeks post receiving their assigned orthotic. The stance phase of walking was divided into 4 subphases (Phase 1: 0 to 17%, Phase 2: 18 to 50%, Phase 3: 51 to 83%, and Phase 3: 84 to 100% of stance) and the maximum rearfoot eversion during each subphase determined.

SECONDARY outcome

Timeframe: Absolute values measured at 5 weeks

Population: The number of participants used for the analysis was based upon the availability of complete data sets.

The maximum electromyographic activity of the lower leg muscles is with respect to the barefoot condition. The electromyographic activity of the lower extremity muscles were recorded during the stance phase of walking while barefoot and while wearing their assigned orthotic (Full Contact or Maximal Arch Subtalar Stabilization). All electromyographic measurements were taken at the 5 week time point. The peak electromyographic activity during the stance phase of barefoot walking was determined. The electromyographic activity during the orthotic condition was amplitude normalized to the barefoot condition by dividing the electromyographic activity of the orthotic condition by the peak barefoot electromyographic activity and multiplying by 100. The stance phase of walking was then divided into 4 subphases (Phase 1: 0 to 17%, Phase 2: 18 to 50%, Phase 3: 51 to 83%, and Phase 3: 84 to 100% of stance) and the peak amplitude normalized electromyographic activity of each subphase det

The forefoot inversion motion during the stance phase of walking with the subject wearing a sandal and their assigned orthotic (Full Contact or Maximal Arch Subtalar Stabilization) was recorded 5 weeks post receiving their assigned orthotic. The stance phase of walking was divided into 4 subphases (Phase 1: 0 to 17%, Phase 2: 18 to 50%, Phase 3: 51 to 83%, and Phase 3: 84 to 100% of stance) and the maximum forefoot inversion during each subphase determined.
