Gait

Question 1

Briefly Define Gait

Answer 1

Normal human gait refers to the style of locomotion achieved through the movement of limbs involving bipedal, biphasic forward propulsion of center of gravity of the body, in which there are alternate synchronized movements of different segments of the body involving minimal expenditure of energy

Question 2

Considering the quantitative parameters of gait explain the following term and give an appropriate standard measurement: Stride length

Answer 2

Distance between successive points of heel contact of the same foot (double the step length)

Question 3

Considering the quantitative parameters of gait explain the following term and give an appropriate standard measurement:Foot angle

Answer 3

The angle of foot placement formed by a line drawn in the direction of travel bisecting a line from the heel to the second toe, normally 7 degs in men

Question 4

Considering the quantitative parameters of gait explain the following term and give an appropriate standard measurement:Cadence

Answer 4

Number of steps per unit of time

Question 5

State the main phases and sub phases of the gait cycle

Answer 5

Stance (60%) and swing (40%) Phase: Sub phases: Initial contact-Loading response-Mid-stance- Terminal stance - initial swing - Mid swing - Terminal swing

Question 6

For one sub phase of gait briefly describe the activity that is occurring

Answer 6

Initial swing begins at toe off and continues until maximum knee flexion (60 degrees) occurs

Question 7

Considering the quantitative parameters of gait; explain the following terms and give an appropriate standard measurement.
 Step length



Answer 7

The distance measured from Right heel

strike to left heel strike

Question 8

Considering the quantitative parameters of gait; explain the following terms and give an appropriate standard measurement.
 Stride width


Answer 8

Distance between the paths taken by the two feet measured between mid heel to mid heel

Question 9

Considering the quantitative parameters of gait; explain the following terms and give an appropriate standard measurement.
 Cycle time

Answer 9

Time for one complete gait cycle. This is the time elapsed from the first contact of one foot with the ground and ending when the same foot again makes contact with the ground.
