A
Normal balance Ans✓✓✓maintain position without support, accepts
maximal challenges and can weight shift in all directions, no limitations
Good balance Ans✓✓✓maintain position without support, access
moderate challenges and can weight shift in all directions, but
limitations are evident
Fair balance Ans✓✓✓maintain position without support, can't tolerate
challenges or weight shifts in all directions
Poor balance Ans✓✓✓pt requires support to maintain position
No balance Ans✓✓✓pt is unable to assist in maintaining position,
requires max assistance to maintain balance
postural balance Ans✓✓✓ability to maintain equilibrium by maintaining
the COM over the BOS within the limits of stability (LOS)
Gait stability Ans✓✓✓the ability to control postural balance during gait
and when changing from one position to another
,vestibular system provides what Ans✓✓✓info regarding the position
and movement of the head (not speed)

vision
vestibular
movement balance strategies Ans✓✓✓reactive, ongoing adjustments
motor output strategies
biomechanics balance strategies Ans✓✓✓COM, LOS, BOS, strength,
length
,ankle strategy Ans✓✓✓used with slow, small perturbations on level
surfaces
-sequence of muscle activity is from distal to proximal
hip strategy Ans✓✓✓used on narrow surfaces or with large-fast
perturbations
-sequence of muscle activity is proximal to distal
stepping strategy Ans✓✓✓used when the center of gravity is outside the
base of support or limits stability
Falls risk factors Ans✓✓✓muscle weakness, history of falls, gait
deficits, using an AD, visual deficits, arthritis, impaired ADL's,
depression, cognition, age > 80, meds

, 4 goals of balance interventions and progression Ans✓✓✓1.
progressively reduce the base of support
2. dynamic movement that perturb the center of gravity
3. stressing postural muscle groups
4. reducing sensory input
sitting balance progression Ans✓✓✓remove UE support
make the surface less stable
add UE activities: reaching and throwing
standing balance progression Ans✓✓✓more challenging positions
compliant surfaces
moving UE/LE
eyes closed
add UE activities
add dual tasks
static balance interventions Ans✓✓✓vary posture
wide to narrow base to tandem to single leg stance
vary support surface: pillow, foam, mats
incorporate external loads
