Exam 12: Posture and Gait in Walking and Running

During normal walking speeds, what percentage of the gait cycle does the stance phase comprise?

Of the following, which is not considered to be an "antigravity" muscle group?

During the terminal stance and pre-swing phases of gait, knee flexion occurs _______ from _______________________________.

During running, it is believed that the quadriceps provides more positive (propulsion) work than negative (absorption) work.

Patients with quadriceps weakness will attempt to keep their knee in greater amounts of flexion especially at and immediately after heel contact.

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

During the loading response, most muscles fire concentrically.

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

What is the number of steps an individual can complete in a period of time known as?

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

What type of recovery strategy is most often used when the challenge is small and slow and remains near the body's midline?

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.

Ground reaction forces are least in this direction:

Mid-stance occurs when the:

Patients with Parkinson's disease commonly demonstrate increased trunk rotation and arm swing.

During mid-stance, which muscle bears the primary responsibility for controlling the pelvis in the frontal plane?

For patients with paraplegia, which hip muscle group is most important for maintaining adequate flexibility so the ability to stand is unaffected?

Gait can be defined as:

An anteriorly directed ground reaction force occurs during which part of the gait cycle?

Patients with patellofemoral pain syndrome typically ambulate with their knee in a flexed posture.
