Describe the compensated trendelenburg gait that occurs with hip pain - ANS ✔-Compensated
trendelenburg gaitshifts GRFV *through* the painful hip joint to *stabilize* the joint and
*decrease* torque
-Without compensation, aBductor muscles have to contract against aDuction moment, which
causes *compression* at hip joint
% of people with Parkinson's disease have difficulty walking within 3 years of diagnosis - ANS
✔*85%* of people with Parkinson's disease have difficulty walking within 3 years of diagnosis
% of people with MS experience mobility problems - ANS ✔*75%* of people with MS
experience mobility problems
% of people who have strokesregain community mobility - ANS ✔*50%* of people who have
strokes regain community mobility
Define *gait* versus *walking* versus *mobility* - ANS ✔-*Gait*: pattern of movement of the
limbs during locomotion
-*Walking*: one form of locomotion
-*Mobility*: ability to safely and independently move from one point to another
List 3 dimensions of the neural control of walking - ANS ✔1. *Sensory*: afferentinput
2. *Spinal cord*: central pattern generators
3. *Supraspinal*: corticalsystemsfor complex navigation (obsticles, etc.) to adapt gait pattern
Define and describe the function of *central pattern generators(CPG)* - ANS ✔-*CPG* =
network of neurons and inter-neurons in spinal cord
-Generate coordinated movements autonomously
-Modified by ascending and descending signals from cortex and the periphery
Name two *ascending sensory inputs* that influence the stance-to-swing transition - ANS ✔-Hip
