Nonlinear Effects of Body Weight on Ground Reaction Force Peaks: Implications for Normalization
Ground reaction force (GRF) measurements are commonly reported in bodyweight (BW) units. Division normalization of this type reduces the contribution of body size differences to the variance among subjects. Several researchers have noted that peak force measurements can remain significantly correlated with BW, even after normalization. Most recently, Wannop et al. [1] examined GRF components an...
متن کاملDetermination of peak vertical ground reaction force from duty factor in the horse (Equus caballus).
Measurement of peak vertical ground reaction force (GRFz) from multiple limbs simultaneously during high-speed, over-ground locomotion would enhance our understanding of the locomotor mechanics of cursorial animals. Here, we evaluate the accuracy of predicting peak GRFz from duty factor (the proportion of the stride for which the limb is in contact with the ground). Foot-mounted uniaxial accele...
متن کاملAgreement between vertical ground reaction force and ground reaction force vector in five common clinical tests.
Mechanography is an innovative method to evaluate lower-limb dynamic muscle function. This technique is generally performed on force platforms that measure only the vertical component of ground reaction force (GRF). The underlying assumption is that medio-lateral and antero-posterior forces do not contribute significantly to the GRF in jumping and rising tests. The goal of this study was to est...
متن کاملBlind Separation of Ground Reaction Force Signals
Blind source separation presents an interest for several applications fields. In this study, focus is on the blind separation of biomechanical signals namely ground reaction force signals. We showed recently in [1, 2], that ground reaction force signals are cyclostationary. Thus, the idea of this paper is to make use of the cyclostationary character of ground reaction force signals to separate ...
متن کاملCyclostationary modeling of ground reaction force signals
The importance of the measurement of human locomotion for the processes of diagnosis and treatment of locomotion disorders is increasingly being recognized. Human locomotion, in particular walking and running are defined by sequences of cyclic gestures. The variability of these sequences can reveal abilities or motorskill failures. The purpose of this study is to analyze and to characterize a r...
