Impaired H-Reflex Adaptations Following Slope Walking in Individuals With Post-stroke Hemiparesis [PDF]

, 2019
Background and Purpose: Short term adaptations in the Ia afferent-motoneuron pathway, as measured using the H-reflex, in response to altered ground reaction forces (GRFs) applied at the feet during slope walking have been observed in the non-impaired ...

Prediction of ground reaction forces while walking in water.

PLoS ONE, 2019
Despite being a key concept in rehabilitation, controlling weight-bearing load while walking, following lower limb injury is very hard to achieve. Walking in water provides an opportunity to prescribe load for people who have pain, weakness or weight ...

Effect of Horizontal Ground Reaction Forces during the Golf Swing: Implications for the Development of Technical Solutions of Golf Swing Analysis

Proceedings, 2020
The swing is a key movement for golf. Its in-field performance could be estimated by embedded technologies, but often only vertical ground reaction forces (VGRF) are estimated.

Ground reaction force sensor fault detection and recovery method based on virtual force sensor for walking biped robots [PDF]

, 2013
This paper presents a novel method for ground force sensor faults detection and faulty signal reconstruction using Virtual force Sensor (VFS) for slow walking bipeds. The design structure of the VFS consists of two steps, the total ground reaction force (

Estimating Running Ground Reaction Forces from Plantar Pressure during Graded Running

Sensors, 2022
Ground reaction forces (GRFs) describe how runners interact with their surroundings and provide the basis for computing inverse dynamics. Wearable technology can predict time−continuous GRFs during walking and running; however, the majority of GRF ...
