Study Notes
Normal Gait Introduction
- The learning objective is to identify components of normal gait.
Gait Cycle (GC)
- A gait cycle starts when a foot contacts the ground and ends with the same foot contacting the ground again.
- Stance phase: The time the foot is in contact with the ground.
- Swing phase: The time after the stance phase when the foot is not in contact with the ground.
Double Support and Single Support
- Double support: Both feet on the ground simultaneously.
- Single support: One foot on the ground, the other in the air.
Components of Gait
- The gait cycle includes phases like heel strike, loading response, midstance, terminal stance, preswing, initial swing, midswing, and terminal swing.
- Each phase involves specific muscle actions and body positioning.
- Stance phase duration accounts for about 60%, and double support and single support periods are both 10% and 40%, respectively.
Spatial Features of Gait
- Step length: Distance covered by each step.
- Stride length: Distance covered from one heel strike to the next.
- Walking base/step width: Distance between the two feet at any point in the gait.
Temporal Features of Gait
- Cadence: The number of steps taken in a given time.
- Speed: Distance covered in a given time.
