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
