Variability in Head Movement during Gait Transitions

Predictions from a model of coupled oscillators, which was based on stationary interlimb coordination, were examined in locomotor intralimb coordination.

Description
Summary:Predictions from a model of coupled oscillators, which was based on stationary interlimb coordination, were examined in locomotor intralimb coordination. The present study measured head linear and angular accelerations and coordination relationships of the head and torso, e.g., using relative phase measures, during walking and running on a treadmill. Head linear acceleration increased from walking to running and decreased from running to walking, and head pitch/torso pitch relative phase decreased from walking to running and increased from running to walking. No other measures were significantly different for either walking or running (head angular acceleration, mean head vertical displacement/head pitch relative phase, SD head vertical displacement/head pitch, and SD head pitch/torso pitch). This information will aid further understanding of the many aspects involved in locomotor coordination.
