balance PP Flashcards
defined as the ability to maintain the body’s center of mass over its base of support (BOS)
Balance
The area contained within the parts of the body making physical contact with the external enviornment
Base of support
3 system linked to balance control
3 legged stool
- Vestibular
- Visual
- Somatosensory
- Musculskeletal and neuromuscular compnents
KC adds to the
3 systems. what do they add?
sensory organization for balance control
Knowing where your body is in space
Input from body regarding its position and movement
Proprioception
Responsible for processing information about movement with respect to gravity
- Rotation, acceleration/deceleration and head stabilization
- Postural control and coordination of eye and head movements
- What are you working on ?
Vestibular system
Allows the information provided by the other systems to be integrated into a whole picture
- Reduced response time, fear and exaggerated responses
Cognitive or Sensory Organization
K & C, pg 263
React to maintain balance in response to the unexpected
Pertubations
HIP STRATEGY
- Occurs with larger LOBs or when unable to use ankle strategy
- Proximal to distal manner
- uses hiop flex or ext to moe the center of mass within the BOS
what muscles kicking in?
- LOB- in anterio direction ?
- LoB in posterio direction?
- ant- lowr back then hamstrng muscles
- Post-lower abs then quads
when LOB is too great and COG is too far off BOS and need to increase area of BOS
Person will step in direction of LOB
Stepping Strategy
Factors that will influence balance strategies
