The Plantar Loading Variations to Uphill and Downhill Gradients During Treadmill Walking

Key Points

The study aims to investigate how different treadmill gradients affect plantar loading during walking.
20 participants walked on a treadmill at five gradient conditions (-15%, -8.5%, Level, 8.5%, 15%)
Plantar loading was measured using the Pedar in-shoe pressure measurement system with EMED insoles containing 99 sensors
Data was collected for the last 20 seconds of each condition.
Increased loading in the hallux and 1st metatarsal regions with higher gradients (PP and PF).
Loading in the heel region increased with negative gradients while decreasing in the 4th and 5th metatarsal regions.

Abstract

The purpose of the study was to examine the plantar loading changes during 5 gradient conditions on a treadmill (-15%, -8.5%, Level, 8.5%, 15%) for 20 participants using the Pedar in-shoe pressure measurement system. The measurement system uses EMED insoles, each consisting of 99 capacitive sensors, sampled at 50 Hz. Data was collected from the last 20 seconds at each gradient condition while participants walked. As the treadmill gradient increased, loading (peak pressure PP and peak force PF) increased in the hallux and 1st metatarsal regions and decreased in the heel region. With negative gradients, loading (PP and PF) increased in the heel region and decreased in the 4th and 5th metatarsal regions.
