Q

postural control vs postural orientation

A

postural control: controlling body’s position in space for stability and orientation
- includes postural reactions

postural orientation: maintain appropriate relationship bet body, body segments and environment

A

aka balance

ability to maintain COM over the BOS

Q

what are postural adjustments

A

patterns of muscle activation and control of segments that allows control reactive to BOS

anticipatory
on going

Q

relate vestibular system to balance

A

1st system that works - upon birth

baby is able to perceive if in supine, prone, sitting

Q

what are the different adapting motor strategies

A

ankle
hip
stepping

strategies depend on degree of perturbation and environment; also the strength and ROM of an individual

backwards sway ankle strategy

A

17
Q

backwards sway hip strategy

A

paraspinals and hams

18
Q

exp stepping strategy

A

hop or step to catch COG inside BOS

if hip and ankle strategy is not enough to adapt

19
Q

explain mediolateral stability

A

occurs at hip and trunk

unloaded - flexors and abductors

loaded - extensors and adductors

use diff strats for diff muscle groups

20
Q

factors influencing sitting balance

A

initial alignment

presence of feet support

distance of reach

21
Q

factors influencing standing balance

A

initial alignment

forthcoming movement

speed and ampli of movement

22
Q

common probs on post stroke pts in terms of balance

A

widened BOS

shifting to normal side

stiffening of body to control

slow movements

moving trunk instead of distal to maintain BOS

avoiding perturbations/challenges

disuse of affected side

improper posture

using of hands to support

23
Q

goals of rehabilitation

A

maintain COG over BOS in any activity

develop the strategies to perturbations

prevent or reduce impairments in systems affecting balance - ROM, MMT

inc LE strength and coordination

refrain functional tasks c varying postural control demands

24
Q

training guidelines on initiating balance training

A

more of head and trunk movements muna then reaching

sitted or standing

master quiet breathing

25
training guidelines on maximizing balance training
inc distance of reaching vary speed dec support inc object weight and size use external timing constraint - catching a ball
26
training guidelines on standing balance training
head and body movements muna reaching then narrow stance to SL side ways walking to inc lateral stab picking up objects
