Quantification of equine ground reaction force patterns

Journal of Biomechanics, 1987
A method was developed to quantify the ground reaction force pattern of the horse. A number of selected force amplitudes and peak-time positions in the normalized stance phase of left and right contralateral limbs were used to calculate symmetry indices. Data from each limb were compared with those of a 'standard horse' resulting in limb indices.

Accuracy and precision of loadsol® insole force-sensors for the quantification of ground reaction force-based biomechanical running parameters

European Journal of Sport Science, 2018
Force plates represent the “gold standard” in measuring running kinetics to predict performance or to identify the sources of running-related injuries. As these measurements are generally limited to laboratory analyses, wireless high-quality sensors for ...

Ground reaction forces in running: A reexamination

Journal of Biomechanics, 1987
Ground reaction force (GRF) data were collected on twenty adult males during running stance to establish normative standards to aid in assessment of the gait of atypical runners. Subjects ran between 30 and 40 trials across a Kistler 0.6 X 0.9 m force platform at self-selected speeds ranging from 2.5 to 5.5 m s-1.

The relationship between foot arch flexibility and medial-lateral ground reaction force distribution.

Gait & Posture, 2019
BACKGROUND Overuse running injury susceptibility has previously been associated with the magnitude and slope of ground reaction force profiles, most often in the vertical axis.

Ground Reaction Forces during Human Standing

Engineering in Medicine, 1983
Foundamental characteristics of ground reaction forces measured by using a force plate during human standing were investigated. Force fluctuation levels and power spectrums of the force data for standing posture were compared with those for sitting.

Ground Reaction Forces During Termination Of Human Gait

Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society Volume 13: 1991, 1992
This is the first published report of the ground reaction forces during gait termination. Two mechanisms appear to be used to stop walking: increased braking forces and decreased push-off force. There appears to be a short interval of time during the gait cycle in which a decision to take an additional step is to be made.

Force treadmill for measuring vertical and horizontal ground reaction forces

Journal of Applied Physiology, 1998
We constructed a force treadmill to measure the vertical, horizontal and lateral components of the ground-reaction forces (Fz, Fy, Fx, respectively) and the ground-reaction force moments (Mz, My, Mx), respectively exerted by walking and running humans. The chassis of a custom-built, lightweight (90 kg), mechanically stiff treadmill was supported along ...

Measuring Equine Ground Reaction Forces

2006
This paper describes the design and development of an instrumented force shoe which allows measurement of three orthogonal components of ground reaction force during locomotion in horses, and presents preliminary GRF data for consecutive strides at walk and trot.

Influence of IMU position and orientation placement errors on ground reaction force estimation.

Journal of Biomechanics, 2019
Wearable inertial measurement units (IMU) have been proposed to estimate GRF outside of specialized laboratories, however the precise influence of sensor placement error on accuracy is unknown.
