    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.
