NPTE-PTA Functional Training and Gait

Question 1

During normal gait, when does the center of mass reach its lowest point?

Accepted Answer

During loading response (foot flat)

Answer

The center of mass reaches its lowest point during double support (loading response) and its highest point during midstance, producing an inverted pendulum pattern.

Question 2

Which assistive device provides the most stability for a patient who is non-weight-bearing on the right lower extremity?

Accepted Answer

Standard walker

Answer

A standard walker provides the greatest base of support and stability for a non-weight-bearing patient, particularly for those with balance and strength limitations.

Question 3

A patient with a right hip replacement is using a cane. In which hand should the cane be held?

Accepted Answer

Left hand (contralateral to the affected hip)

Answer

The cane is held in the contralateral (left) hand so it advances with the affected right leg, reducing the load on the hip abductors and the involved joint.

Question 4

Which gait pattern is safest for a patient who is touch-down weight-bearing (TDWB) using axillary crutches on a staircase going up?

Accepted Answer

Lead with the unaffected leg up, then bring crutches and affected leg

Answer

The mnemonic 'good goes up, bad goes down' applies: the unaffected leg leads going up stairs, and the affected leg leads going down stairs.

Question 5

What is the primary purpose of the push-off phase (terminal stance to pre-swing) in the gait cycle?

Accepted Answer

Forward propulsion of the body

Answer

The push-off phase generates forward propulsion via ankle plantarflexion, providing the energy needed to advance the limb into swing and propel the body forward.
