Gait Functions

Question 1

Locomotor Functions (4)

Answer 1

Propulsion
Shock absorption
Stance stability
Energy conservation

Question 2

Postural Sway Mechanisms (2)

Answer 2

Cardiac dynamics

Lack of absolute positional sense (proprioception).

Question 3

Functional Rockers (4)

Answer 3

Heel rocker
Ankle rocker
Forefoot rocker
Toe rocker

Question 4

Heel Rocker

Answer 4

Preserves momentum from forward fall into a facilitation of progressing the entire stance limb (0-12% of gait cycle).

Question 5

Ankle Rocker

Answer 5

Ankle becomes the fulcrum for continue progression once the forefoot strikes the floor, rolling forward in response to the preserved momentum (~12-31% of gait cycle).

Question 6

Forefoot Rocker

Answer 6

As heel rises, metatarsals act as rod of axis. As body weight shifts forward, progression is accelerated (~31%-50% of gait cycle).

Question 7

Toe Rocker

Answer 7

Toe only contact as the leg begins to be unweighted. Elastic recoil of the PF thrust tibia forward for accelerated limb advancement (~50-62% of gait cycle).
