Three-Axis Ground Reaction Force Distribution during Straight Walking

Sensors, 2017
We measured the three-axis ground reaction force (GRF) distribution during straight walking. Small three-axis force sensors composed of rubber and sensor chips were fabricated and calibrated.

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 (

Ground reaction force estimates from ActiGraph GT3X+ hip accelerations. [PDF]

PLoS ONE, 2014
Simple methods to quantify ground reaction forces (GRFs) outside a laboratory setting are needed to understand daily loading sustained by the body. Here, we present methods to estimate peak vertical GRF (pGRFvert) and peak braking GRF (pGRFbrake) in ...

The Effect of Foot Orthosis on the Vertical Component of the Ground Reaction Force While Walking: A Review Study

Journal of Rehabilitation, 2021
Objective Everyone is required to walk and stand for long time in daily activities, especially in the workplace. As a result, the Ground Reaction Force (GRF) on the components and joints is so great that they sometimes reach several times the weight of ...

Comparison of vertical ground reaction forces during overground and treadmill running. A validation study

BMC Musculoskeletal Disorders, 2012
Background One major drawback in measuring ground-reaction forces during running is that it is time consuming to get representative ground-reaction force (GRF) values with a traditional force platform.

Sexual Dimorphism Impact on the Ground Reaction Force Acting on the Mediolateral Direction During Level Walking: Hip Abductor Muscle Biomechanics and Its Correlation to GRF Moment Arm

Frontiers in Bioengineering and Biotechnology, 2022
The female pelvis morphology represents an evolved compensation between two opposing needs: a broad pelvis enough to deliver a sizeable brained offspring while remaining narrow enough to allow for effective bipedal gait.

Ground Reaction Force in Sit-to-stand Movement Reflects Lower Limb Muscle Strength and Power in Community-dwelling Older Adults

International Journal of Gerontology, 2015
Background: Ground reaction force parameters in a sit-to-stand (STS) movement can be used to evaluate lower extremity function. Few reports, however, are available on whether the ground reaction force parameters in an STS movement reflect dynamic knee ...

A Noise-Immune Kalman Filter and Modelling forPedestrian Traffic Loads

Shock and Vibration, 2020
The definition of design load with walking crowd excitation on these slender structures is a significant problem to human-induced vibration. To capture the characteristics of walking crowd loads, this article researches both the ground reaction force and

Relationship between angle and peak vertical ground reaction force estimation in parachute landing fall among army parachutists using mathematical modelling

Alexandria Engineering Journal, 2022
This paper discussed the relationship between angle and the value PvGRF for the execution of parachute landing. The value of PvGRF has been determined by using mathematical modelling principle of conservation of energy.
