Question | Answer |
Postural activation patterns can be divided into what tow parts? | Preparatory phase & Compensatory Phase |
Preparatory phase | Postural muscles are activated in response to the direction of the reach (if forward, then posterior muscles are recruited, if sideways, then contralateral postural muscles (lateral flexors) |
Compensatory Phase | After the movement is complete, postural muscles are again recruited in a feedback manner, to stabilize the body further. |
There is a pre-selection of the postural adapter muscles referred to as a ___________? | Central Set:refers to a state of the nervous system that is influenced or determined by the context of the taskā¦or anticipated task |
What muscles are weaker in those with back pain and do not fire like healthy persons for postural sets? | TVA, internal obliques, and lumbar multifidi |
Gait: What areas are responsible for CPG? | spinal cord, brainstem, cerebellum, basal ganglia, vision, cerebral input. |
Gait: Spinal Cord | Reflexive gait |
Gait: Cerebellum and Brainstem | Timing and Task Specific Adapatations (like stepping higher or lower) |
Gait: Basal ganglia | Dynamic Stability and Postural Tone |
Gait: Vision | Need to gain typical gait pattern that allows adjustment for rough terrain |
Gait: Brain adds (assuming visual and cortex) | Vision Orientation to novel Situations Spatial orientation |
What happens when we remove sensation from gait? | 1) Slow Down 2) Steps become stereotypical 3) Balance is poor |
Vision for Reactive strategies help us determine...? | 1) our speed 2) influence our bodies alignment in space (PERCEPTION of our visual field1) |
How do we initiate gait? | 1) Reduction of activity in gastroc/soleus 2) Activation of the TIb Anterior 3) GRFV moves toward stance leg, while moving leg swings and dorsiflexors become active |
