Where in the gait cycle will your patient require the most muscle strength of the plantar flexors?

The patient with low back dysfunction is demonstrating a gait deviation consistent with weak hip extensors.  Which of the spinal levels should the physical therapist assume is being impacted by the patient’s intervertebral disc bulge?

(Bonus) What rocker would a high ankle sprain cause the most discomfort due to nature of injury?

Which of the following correctly depicts the maximal amount of hip extension/flexion range of motion during normal gait? (I will call it “excursion” sometimes)

The patient with severe arthritis in the ankle had a fusion so the ankle is now locked in neutral, 0 degrees. His pain is markedly less.  Now he has typical gait deviations because his ankle is “stuck” at a neutral position.  What will the physical therapist see?

When the therapist is performing gait analysis, he notes that the patient’s pelvis is dropping abnormally (excessive pelvic abduction) on the ipsilateral side during the initial contact/loading response, which of the following impairments are most likely occurring?

At the end of loading response, what type of external moment occurs at each joint in the sagittal plane as a result of the body vector at the ankle, knee, hip? (Please note EXTERNAL not INTERNAL)

Your patient, who is deconditioned, has started a walking program (they have increased their velocity of gait significantly), and the following day, your patient experiences Delayed Onset Muscle Soreness (DOMS), especially in the hamstrings. What part of the Gait Cycle is most likely responsible for this condition?

A child talks out of turn in class. Each time, the teacher assigns extra written work immediately following the behavior. Over time, the child’s interruptions decrease significantly.

Field researchers who are particularly concerned with making sure they obtain a sample that is representative of selected characteristics of a population would employ:
