Gait Questions with Correct AnswersA PT observe a pt during gait training. The pt has normal strength &
equal leg length. The pt slightly vaults & exhibits early heel off during
midstance. Which of the following impairments is the MOST likely
cause of this deviation? (930)
1. Weakness of dorsiflexors
2. Weakness of hip abductors
3. Limited plantar flexion
4. Limited dorsiflexion Correct Answer-4. Limited dorsiflexion
Limited DF --> vaulting or bounce through mid-late stance, require
10deg of DF
Weakness of DF --> steppage gait
Limited PF --> 15 deg during loading, 20 during pre-swing
Weakness of hip abduction --> Trendelenburg sign
A patient sustained a grad e II strain to the iliopsoas muscle. Which of
the following phases of the gait cycle should the PT expect to be the
MOST impacted by this injury? (941)
1. Toe off (pre-swing) and acceleration (initial swing)
2. Heel strike (initial contact) and acceleration (initial swing)
3. Foot flat (loading response) and deceleration (terminal swing)
4. Midstance and deceleration (terminal swing) Correct Answer-1. Toe
off (pre-swing) and acceleration (initial swing)
, Iliopsoas eccentrically from midstance to terminal swing, concentrically
from toe off to acceleration.
Heel strike - hip extensors active
Foot flat --> hip extensors work concentrically to extend hips then
eccentrically during terminal swing to slow hip flexion & knee
extension. Iliopsoas not active in these stages
Midstance --> hip abductors active concentrically to prevent hip drop,
iliopsoas eccentrically to control hip extension.
A patient who has been on bed rest for three weeks has developed a
plantar flexion contracture. Which phase of the gait cycle would be the
MOST problematic for the patient based on the described impairment
(952)
1. Heel strike to foot flat
2. Foot flat to midstance
3. Midstance to heel off
4. Heel off to toe off Correct Answer-3. Midstance to heel off
Heel strike to floot flat --> 0 to 15deg PF
Foot flat to midstance --> 15 to 0 deg DF
Midstance to heel off --> 0 to 15 deg DF
Heel off to toe off --> 15 deg DF to 2- deg PF (mostly involve
plantarflexion)
A physical therapist observes the gait of a patient following a lateral
