5.2 Balance Training Flashcards
What is the ability to align body segments against gravity to maintain or move the body within the available BOS without falling; the ability to move to body in equilibrium with gravity via interaction of the sensory and motor systems
Balance
What is the ability of the neuromuscular system through synergistic muscle actions to hold a proximal or distal body segment in a stationary position or to control a stable base during superimposed movement
Stability
What is the interaction of the sensory and motor systems that enables synergists, agonists and antagonists, as well as stabilizer and neutralizers, to anticipate or respond to proprioceptive and kinesthetic information & subsequently to work in correct sequence and magnitude to create coordinated movement
Neuromuscular control
What is the correct timing and sequencing of muscle firing combined with the appropriate intensity of muscular contraction leading to the effecting initiation, guiding, and grading movement
Coordination
What is a point that corresponds to the center of the total body mass & is the point at which the body is in perfect equilibrium
Center of Mass (COM)
What is the vertical projection of the COM to the ground; located slightly anterior to the second sacral vertebra
Center of Gravity (COG)
What is the product of the mass times velocity
Momentum
What is the velocity of the body along a straight path
Linear Momentum
What is the rotational velocity of the body
Angular Momentum
What is the perimeter of the contact area between the body and its support surface
Base of Support
What is the sway boundaries in which an individual can maintain equilibrium without changing his/her BOS
Limits of Stability
What is the contact between our bodies and the ground due to gravity (action forces) is always accompanied by a reaction from it
Ground Reaction Force
What is the location of the vertical projection of the ground reaction force; it is equal and opposite to the weighted average of all the downward forces acting on the area in contact with the ground
Center of Pressure
What are the 3 sensory systems?
Visual, Somatosensory, Vestibular
What is this motor strategy?
Observed during balance tasks when persons quickly lower their body COM by flexing the knees causing associated flexion of the ankles and hips
Suspension Strategy
