what is active lengthening in skeletomotor control?
The TA muscle tries to contract when you step down. So it is being expanded but is trying to contract. (going down the mountain). Loading determines muscle activity.
requirements for muscular activation and function during ramp walking
biceps femoris muscle silenced and iliopsoas muscle active during stance for downslope walking
check slides for details
modulation of muscular pattern by a body orientation signal
tonic neck + labyrinthine reflexes provide a body orientation signal
check the slides for details and diagram
difference between level, up and down

limb stiffness is modulated by body orientation signal
orientation of endpoint stiffness - stiffness is greatest along the long axis of the limb
limb stiffness is regulated by sensory feedback
regulation of muscle and limb stiffness by proprioceptive (length and force) feedback
check slides for diagram
measurement of autogenic and intermuscular feedback
