Question 1

Gait characteristics of the very young and the very old have few, if any, similarities.

Accepted Answer

Both the very young and the very old often exhibit similar gait characteristics, such as shorter stride length, wider base of support, and slower walking speed, due to developmental and degenerative changes, respectively.

Accepted Answer

The answer of Patients with patellofemoral pain syndrome typically ambulate...

Question 3

Accepted Answer

The answer of On average, men walk faster had a...

Question 4

The body's center of mass is highest during double limb support.

Accepted Answer

During double limb support, the body's center of mass is actually at its lowest point because both feet are in contact with the ground, providing a stable base of support. The body's center of mass is highest during single limb support, when only one foot is in contact with the ground, and the body must use more energy and control to maintain balance.

Question 5

The gait cycle is synonymous with a stride.

Accepted Answer

The gait cycle is the sequence of events that occur in a single step including heel strike, mid-stance, push-off, and swing through. A stride is the distance covered in two steps or one gait cycle for a specific leg.

Question 6

During the loading response, most muscles fire concentrically.

Accepted Answer

During the loading response, most muscles fire eccentrically to control the motion of the body as it accepts weight, providing shock absorption and stability.

Question 7

A mature gait pattern takes several years to develop.

Accepted Answer

A mature gait pattern involves the alignment and coordination of bones, joints, muscles, and nerves, which takes several years of normal development and growth to achieve. It is not present in infants or toddlers, but gradually develops during childhood and into adolescence.

Question 8

As it relates to sagittal plane motion at the pelvis during gait, anterior tilting of the pelvis is generally associated with hip extension, whereas posterior tilting of the pelvis is generally associated with hip flexion.

Accepted Answer

This is true. During gait, when the pelvis tilts anteriorly, it is typically as a result of hip extension. Conversely, when the pelvis tilts posteriorly, this is generally associated with hip flexion.

Question 9

The vertical ground reaction force during the gait cycle exceeds body weight during mid-stance.

Accepted Answer

During mid-stance, the vertical ground reaction force is typically equal to body weight, as the body is supported by one leg and the force is balanced. It exceeds body weight during other phases like loading response and push-off.

Question 10

To ambulate with a normal gait pattern, extension of the first metatarsophalangeal joint must be possible to 60$\degree$.

Accepted Answer

This statement is true. Extension of the first metatarsophalangeal joint (big toe joint) is necessary for normal walking, and it should be able to move to approximately 60 degrees.

Question 11

From a kinesiological perspective, the determinants of gait attempt to explain the efficiency of gait by detailing how the body minimizes vertical and lateral displacement of the center of mass.

Accepted Answer

This statement accurately reflects the kinesiological perspective on the determinants of gait, which aim to understand how the body reduces unnecessary movements and energy expenditure during walking by keeping the center of mass as stable as possible.

Question 12

The duration of double support varies inversely with the speed of walking.

Accepted Answer

As the speed of walking increases, the duration of double support decreases. This is because at faster speeds, there is less time for both feet to be on the ground at the same time. Therefore, the statement is true.

Question 13

At initial contact the center of pressure is just medial to the midpoint of the heel.

Accepted Answer

The answer of At initial contact the center of pressure...

Question 14

The center of pressure is the location of the foot where the ground reaction forces are applied.

Accepted Answer

The center of pressure is the point on the foot where the resultant of all ground reaction forces acts.

Question 15

The body's center of mass is at its highest in the sagittal plane and its most lateral position in the frontal plane at the same during the gait cycle.

Accepted Answer

The body's center of mass is at its highest in the sagittal plane and its most lateral position in the frontal plane at the same during the gait cycle.

Question 16

A forward head posture decreases the demand on the cervical extensor muscle.

Accepted Answer

A forward head posture puts more strain on the cervical extensor muscles as they have to work harder to hold the head up against gravity. This can lead to muscle fatigue, tension, and potential pain.

Question 17

There are fewer muscles working during the swing phase of gait compared with during the stance phase.

Accepted Answer

During the swing phase of gait, there are fewer muscles involved in the movement compared to the stance phase where multiple muscles work together to support the body weight, maintain balance and propel forward motion. During the swing phase, the movement is primarily driven by gravity and momentum.

Question 18

In most clinical settings, gait analysis routinely incorporates the use of video capture for kinematic analysis and kinetic quantification of forces as these methodologies are inexpensive, readily available, and easy to use.

Accepted Answer

While video capture is commonly used for kinematic analysis in gait analysis, kinetic quantification typically requires specialized equipment such as force plates or pressure sensors, which are more expensive and complex to use.

Question 19

At initial contact, the subtalar joint is in an everted position.

Accepted Answer

At initial contact during gait, the subtalar joint is typically in an inverted position to help absorb shock and adapt to uneven surfaces.

Question 20

Each individual has a comfortable walking speed on a smooth, level surface that is most energy efficient for that individual.

Accepted Answer

This statement is true. Each individual has a comfortable walking speed on a smooth, level surface that is most energy-efficient for that individual, often referred to as their preferred walking speed. This speed varies among individuals depending on factors such as age, height, weight, and overall fitness level.
