Force platforms are considered a gold standard for measuring postural alignment in static and dynamic tasks.
This test assesses reactive postural control in response to anterior and posterior perturbations induced by movements of the
force platform surface.
The subject's jump performance was evaluated for all jumping conditions using kinetic data obtained from the
force platform. The ground reaction force (GRF) was taken as the highest force recorded on the force time record for the takeoff phase of each jump.
Markers were also placed on the
force platform, the SLED frame, the seat back, and the rolling platform.

Figure 1 depicts exemplar EMG and
force platform recordings from the quiet stance assessment.
At baseline and after 12 months all subjects were evaluated with a compass-needle pocket goniometer (IncliMed(r)) for spinal mobility and a
force platform balance, with eyes both open and shut.
The investigators also conducted a gait analysis using six cameras and a
force platform. The participants walked across the platform, and "from this we can determine the loads on the joints," Dr.

Since crutch use changes the center of gravity, the crutch tips were placed in standardized positions on the
force platform such that the velocity of sway was calculated within a theoretical center of gravity with the different types of crutches.
