Walking
- Walking allows us to move our bodies through
space.
- It involves the integration of movements at all
joints of the lower limb and incorporates many of
the powerful muscles associated with the lower
limb.
- Coordinated movements are required to walk
- During walking our feet can adapt to a given
terrain and maintain the stability of the foot thus
allowing propulsion.

How we walk
-Walking is also called gait
-During walking our feet and lower limbs move in a cycle of repeated motions; the gait cycle.
-During gait the bones that comprise our ankle joint (*recap from previous slides* Talus, and lower parts of the Tibia and
Fibula) adopt special actions which allow the gait cycle to occur:
-Pronation
-Supination
-There are two phases to the gait cycle
-Stance phase
-Swing phase

Stance Phase (60% of the cycle)
-Begins when the heel of the foot makes contact with the ground and ends when the toe of the same limb leaves the
ground.
-Broken into three distinct parts
-Heel Strike
- heel touches the ground absorbing impact
-Mid Stance
-foot is flat on the ground . The foot adapts to the terrain and the
weight of the body is supported by the limb
-Toe Off
-foot breaks contact with the ground and body is propelled
forward.

Toe off
Swing Phase (40% of the cycle)
- This is the unsupported phase
-Begins when the foot is no longer in contact with the ground.
-Occurs due to the contraction of the gluteal and thigh muscles
(*link to lower limb muscles*)lifting the leg clear of the ground.
