Joints Muscles Nerves Vision Vestibular/auditory system
How does gait change in the elderly?
↓ speed ↓ stride length ↓ arm swing ↓ rotation of the pelvis ↑ time with feet on the floor ↑ stooped forward ↑ shuffle

↓ muscle contraction
↑ stability
Where is the line of gravity when standing?
Anterior to S2 vertebrae
Slightly posterior to hip joint
