Ground reaction force complexity in hallux valgus

Clinical Biomechanics, 2021
Investigating the complexity of movement systems can be insightful in clinical decision making. The study conducted to evaluate whether complexity of ground reaction force is affected by hallux valgus grades and footwear or foot side conditions.A sample of 120 females including 30 participants in each group of healthy and mild, moderate, and severe ...

Prediction of ground reaction force and joint moments based on optical motion capture data during gait.

Medical Engineering and Physics, 2020
The standard camera- and force plate-based set-up for motion analysis suffers from the disadvantage of being limited to laboratory settings. Since adaptive algorithms are able to learn the connection between known inputs and outputs and generalise this ...

Normalization of Ground Reaction Forces

Journal of Applied Biomechanics, 2006
The appropriateness of normalizing data, as one method to reduce the effects of a covariate on a dependent variable, should be evaluated. Using ratio, 0.67-nonlinear, and fitted normalizations, the aim of this study was to investigate the relationship between ground reaction force variables and body mass (BM).

Ground reaction forces in children's gait

Journal of Biomechanics, 1988
Ground reaction force patterns during walking were observed in 18 children 3 and 4 years of age. The children walked barefoot at a self-chosen walking pace. Selected variables representing the vertical, anteroposterior, and mediolateral force components were evaluated.

Ground reaction forces in distance running

Journal of Biomechanics, 1980
Abstract Ground reaction forces and center of pressure (C of P) patterns were studied in 17 subjects running at 4.5 ms −1 . The subjects were classified as rearfoot or midfoot strikers according to the location of the C of P at the time of first contact between foot and ground.

Controlling the Ground Reaction Force during Lifting

Journal of Motor Behavior, 1995
The control of the ground reaction force vector relative to the center of gravity (CoG) was examined while subjects performed a back-lifting task. Six male subjects (aged 24.0 +/- 2.5 years) repeatedly lifted a barbell. A biomechanical analysis that used a linked segment model revealed that the summed rotations of body segments during lifting yielded a

Validation of a wireless shoe insole for ground reaction force measurement

Jurnal sport science, 2018
Ground reaction force measurements are a fundamental element of kinetic analyses of locomotion, yet they are traditionally constrained to laboratory settings or stationary frames. This study assessed the validity and reliability of a new wireless in-shoe

Estimation of vertical ground reaction force during running using neural network model and uniaxial accelerometer.

Journal of Biomechanics, 2018
Wearable technology has been viewed as one of the plausible alternatives to capture human motion in an unconstrained environment, especially during running.

Characteristic Ground-Reaction Forces in Baseball Pitching

The American Journal of Sports Medicine, 1998
Overhand throwing requires contributions from and interaction between all limb segments. Most previous investigations have concentrated on the throwing arm itself, yet poor mechanics at the arm may originate in the lower extremities. Multicomponent ground-reaction forces of both the push-off and landing limbs were measured in six collegiate and one ...

Ground reaction force across the transition during sprint acceleration

Scandinavian Journal of Medicine & Science in Sports, 2019
Abrupt changes in kinematics during sprint acceleration called transitions have previously been observed. This study aimed to examine whether ground reaction force (GRF) variables during sprint acceleration also show specific features of the transitions.
