Ch 10 - Balance

Question 1

Balance

Answer 1

when body is in equilibrium and stationary, meaning no linear or angular movement

Question 2

Dynamic balance

Answer 2

ability to move and change directions under various conditions

Question 3

Requirements for balance

Answer 3

optimal length-tension relationships, optimal force-couple relationships, optimal joint dynamics, and neuromuscular efficiency using visual, inner ear, and proprioceptive input

Question 4

Causes of altered balance

Answer 4

muscle imbalances, joint dysfunction, pain, swelling

Question 5

Limit of stability

Answer 5

distance outside of base of support you can move into without losing control of center of gravity

Question 6

Balance stabilization exercises

Answer 6

have little joint motion of balance leg; free leg, arms, and core move in slow and controlled manner; improve reflexive (automatic) joint stabilization contractions to increase joint stability; slow tempo; start on stable surface

Question 7

Balance strength exercises

Answer 7

use dynamic concentric and eccentric movement of balance leg through full ROM, requiring dynamic control in mid-range and isometric stabilization at end-range; medium tempo

Question 8

Balance power exercises

Answer 8

develop deceleration ability, eccentric strength, dynamic neuromuscular efficiency, and reactive joint stabilization; hopping movements
