BIOMECHANICS OF THE FOOT
Biomechanics involves the study of:
- The movements patterns of the joints
- Forces acting in muscles and joints
Kinetics – The study of force, mass and weight movements without concentrating on body posture
Kinematics – Movements of the body without referring to the forces involved
- Temporal and Spatial Parameters of Gait
- Movement of Body Segments
Inverse Dynamics – Combines kinetics and kinematics – used to calculate forces and joint movements
Assessing Gait Cycle – Duration when foot is in contact with the ground (stance phase, 60%), and the period when it is not (swing phase, 40%):
Stance Phase:
- Heel Strike
- Foot Flat
- Mid Stance – Point where body is directly over the foot
- Heel Off
- Toe Off
This phase involves the foot being in contact with the floor
Swing Phase:
- Early Swing
- Mid Swing
- Late Swing
This phase involves the foot not being in contact with the floor
Spatial Parameters Distance
Temporal Parameters
- Step time - this is the time between two consecutive heel strikes
- Stride time - this is the time between two consecutive heel strikes by the same leg, one complete gait cycle.
