People who developed pain used a lumbar > hip initiation of movement (spine moves first followed by pelvic/hip movement) strategy on arising from the flexed position while non-pain developers used a hip > lumbar strategy (p = 0.03).
Friction is a function of both normal (compressive) force and the coefficients of friction the amount of resistance to the initiation of movement (static frictional coefficient) or the resistance to movement (dynamic coefficient of friction).
In particular, VTA non-DA neuron firing rates increase markedly at the initiation of movement [21] and their activity correlates with the velocity or acceleration of animal's movement [24].
This retraction event initiated 32 ± 22 s after microtubule alignment, which coincided with the initiation of movement away from the colliding partner.
Lastly, baboons seem to use vocalisations on a context-dependent basis: grunts and loud calls were emitted more often before the initiations of movement than after an initiation or within other contexts.
Other factors such as the size and shape of the valley along with variations in slope direction, properties of the subsoil, and vegetation also have an influence on the initiation and movement of debris flows.
This hypothesis assumes the existence of a gating mechanism during conditions of uncertainty that locks the initiation of movement before any stimulus is presented and thus increases the RT to any targets that are not preceded by warning cues.
The motor behaviors before stepping might be due to the conditions prior to the initiation of movement.
This brain circuit is crucial for the initiation of movement and plays an important role in multisensory integration, especially proprioceptive-motor integration [28].
