Wheelchair propulsion kinetics#

This dataset was recorded at the Mobility and Adaptive Sports Research Lab.

These are the 3D kinetics (3 forces, 3 moments) applied by a wheelchair user on an instrumented pushrim, during wheelchair propulsion from stop. Data are sampled at 240 Hz and are expressed as a TimeSeries.

Coordinate system: x is forward, y is upward, z is lateral, in the wheelchair reference frame.

TimeSeries contents#

Definition

Forces

Nx4 array consisting where each line is \([F_x, F_y, F_z, 0.0]\).

Moments

Nx4 array consisting where each line is \([M_x, M_y, M_z, 0.0]\).
