Gait Analysis Questions with Correct AnswersThe Objectives of Normal Gait...? Correct Answer-Perform a repetitive
sequence of limb motions.
Progress the body.
Maintain weight-bearing stability.
Conserve energy.
Absorb impact shock.
Normal gait is? Correct Answer-Fluid
Symmetrical
Efficient
What is walking? stance? energy? PT concern? Correct Answer-
WALKING USING A REPETITIOUS SEQUENCE OF LIMB
MOTION TO MOVE THE BODY FOWARD WHILE
SIMULTANEOUSLY MANTAINING STANCE STABILITY USING
THE LEAST AMOUNT OF ENERGY. SINCE PT ARE PRIMARILY
CONCERNED WITH RESTORING NORMAL MOTION, AN
UNDERSTANDING OF THE MECHANICS OF GAIT IS
NECESSARY.
Gait Cycle (GC)? Correct Answer-A single sequence of events b/w 2
sequential initial contacts by the same limb
Stance Phase? Correct Answer-The entire period the limb is in contact
with the ground (Initial contact - Preswing, N-62% of GC)
,Swing Phase? Correct Answer-Foot is not in contact with floor. (Initial
Swing, Mid Swing, Terminal Swing N- 38% of GC)
Stride? Correct Answer-- A SINGLE SEQUENCE OF EVENTS FOR
ONE LIMB, divided into stance and swing.
The distance between heel strike to the next ipsilateral heel strike.
Step? Correct Answer-- TIMING B/W 2 LIMBS, 2 STEPS IN EACH
STRIDE.
The distance from heel strike of one foot to heel strike on the
contralateral foot
% of time spent in double support? Correct Answer-12%
What happens to stance and swing times as velocity increases? Correct
Answer-TOTAL STANCE AND SWING TIMES ARE SHORTENED
AS GAIT VELOCITY INCREASES
... Correct Answer-
Cadence? Correct Answer-Number of steps (right and left) per unit of
time. Step rate/min.
,Velocity? Correct Answer-The speed of walking in a designated
direction. Human gait velocity is a function of cadence and average step
length.
V=Stride length x 0.5 Cadence.
THE SPEED OF WALKING IN A DESIGNATED DIRECTION,
NORM ADULT CUSTOMARY WALKING VELOCITY - 82M/MIN;
DESIGNATED IN M/MIN, FT/SEC, M/SEC, FT/MIN
CLINICALLY SEEN AS M/MIN IN ORDER TO BE COMPATILE
WITH THE MORE UNDERSTANDABLE DESIGNATION OF
CADENCE (STEPS/MINUTE)
THE PRIMARY DETERMINANTS OF GAIT VELOCITY ARE THE
LENTH AND REPETITION RATE OF THE PERSON'S STRIDE
Average velocity, step length, stride length, cadence, and step width?
Correct Answer-Velocity: Average adult walks at 3.2 miles/hour (82
meters/min)
Step Length: Adult average is 30 inches
Stride Length: Adult average is 55.1 inches (1.4 meters)
Cadence: Average is 113 steps per minute (not strides)
Step Width: 2-4 inches
, Rise? Correct Answer-Rise: Refers to the transition to, or the maximum
upward, vertical displacement of the head and trunk (center of mass)
during the gait cycle.
Fall? Correct Answer-Fall: Refers to the transition to, or the point of
lowest vertical displacement of the head and trunk (center of mass)
during the gait cycle.
Lateral Excursion/STEP WIDTH? Correct Answer-Lateral
Excursion/STEP WIDTH: Refers to the displacement of the head and
trunk (center of mass) away from its central position along the line of
progression.
... Correct Answer-
... Correct Answer-
... Correct Answer-
Line of progression? Correct Answer-Line of Progression: the line
approximately at the center point between both feet along the subject's
path when walking forward.
What are the 3 functional tasks of gait? Correct Answer-1.) Weight
acceptance
2.) Single limb support
