DownloadDescribe the compensated trendelenburg gait that occurs with hip pain.
Flip card
Compensated trendelenburg gait shifts GRFV through the painful hip joint to stabilize the joint and decrease torque. Without compensation, abductor muscles have to contract against adduction moment, which causes compression at the hip joint.
What percentage of people with Parkinsons disease have difficulty walking within 3 years of diagnosis?
Flip card
85% of people with Parkinsons disease have difficulty walking within 3 years of diagnosis.
What percentage of people with MS experience mobility problems?
Flip card
75% of people with MS experience mobility problems.
What percentage of people who have strokes regain community mobility?
Flip card
50% of people who have strokes regain community mobility.
Define gait versus walking versus mobility.
Flip card
Gait refers to the pattern of movement of the limbs during locomotion. Walking is one form of locomotion. Mobility refers to the ability to safely and independently move from one point to another.
List 3 dimensions of the neural control of walking.
Flip card
1. Sensory: afferent input
2. Spinal cord: central pattern generators
3. Supraspinal: cortical systems for complex navigation (obstacles, etc.) to adapt gait pattern.
Define and describe the function of central pattern generators (CPG).
Flip card
CPG is a network of neurons and inter-neurons in the spinal cord that generate coordinated movements autonomously. They are modified by ascending and descending signals from the cortex and the periphery.
Name two ascending sensory inputs that influence the stance-to-swing transition.
Flip card
Hip extension and unloading of ankle plantarflexors.
