Q

Development of postural control - Sitting

A

Coordinate head control with trunk
Develop synergistic patterns of control
Once ind sitting, then feed forward in trunk is seen prior to UE movement

Q

Development of stance postural control

A

LE force production greater than body weight at 6 months
Progression distal to proximal with ankle strategy first
Development constrained by neural maturation
All strategies by 7-10 y/o
Amplitude and velocity of sway reaches adult levels at 12-15 y/o

Q

Methods to maintain postural control

A
  1. Maintain static balance/posture against perturbation (steady state)

Q

Categories of Balance Tests

A
  1. Quiet standing
  2. Active Standing - dynamic with voluntary weight shifts
  3. Sensory manipulation - altered sensory cues to test adaptation
  4. Functinal Scales with whole body and functional tasks
