Gait Analysis

Question 1

What is Gait Analysis?

Answer 1

Sytematic study of locomotion
Augmented by instrumentation
To measure body movement, mechanics and activity of muscles

Question 2

What Constitutes Gait?

Answer 2

Pattern of movement of limbs during locomotion

Can be walking jogging or running

Question 3

What is the objective of gait?

Answer 3

Perform repetitive sequence of limb motions
Move body forwards
Maintain stability
conserve energy
Absorb impact shock

Question 4

What is the definition of gait cycle?

Answer 4

Time from one event (usually initial contact) of one foot to the same event of same foot
Single sequence of events with one limb

Question 5

What are the sections of the gait cycle?

Answer 5

Stance phase (60%)
Swing Phase (40%)

Question 6

How are the stance and swing phases broken down further?

Answer 6

STANCE PHASE- Double limb stance; single limb stance; Double limb Stance
SWING PHASE- initial swing; mid-swing; terminal swing

Question 7

What is cadence?

Answer 7

Steps within given time (minute)

Unit= Steps/minute

Question 8

What is the Equation for Cycle/Stride time?

Answer 8

Cycle Time (s)= 120/ cadence

Question 9

What is the equation for gait speed?

Answer 9

Speed (m/s)= stride length (m) x cadence (steps/min)/ 120

Question 10

what is an alternate way to break down the stance and swing phase?

Answer 10

STANCE PHASE- heel strike; foot flat; mid stance; heel off; toe off
SWING PHASE- acceleration; mid swing; deceleration
