In this article, we will solve 10 MCQs on Biomechanics (Part-II). So, let’s get started.
Questions and Answers (Correct answers in bold)
Q1. The specific gravity of the human body is:
- 1.995
- 0.095
- 0.95
- 9.05
Q2. Normally in the standing position the centre of gravity lies:
- 5 cms anterior to second sacral vertebrae
- 5 cms posterior to second sacral vertebrae
- Around umblicus
- 5 cms anterior to second sacral vertebrae
Q3. Vector is a physical force that has:
- Magnitude
- Direction
- Both magnitude and direction
- Fixed point of application of force
Q4. In second order level the arrangement is:
- Weight in middle, fulcrum and effort point on either end
- Fulcrum in middle, weight and effort point on either end
- Effort point in middle, weight and fulcrum on either end
- None of the above
Q5. The body’s center of gravity in an adult normally has up and down movements of:
- 1.5 inch
- 2.5 inch
- 3.5 inch
- 4.5 inch
Q6. A therapist examines joint play movement by placing the joint in resting position. The position is best described as:
- Maximal congruency between the articular surfaces and joint capsule
- Minimal congruency between the articular surfaces and the joint capsule
- Passive separation of the joint surfaces is limited
- Parallel to the joint treatment line
Q7. If a plumb line is positioned laterally to a patient so it runs along the line of gravity, where should the line fall with respect to the midline of the knee:
- Anterior
- Posterior
- Directly through the knee joint
- Posterior and medial
Q8. A physical therapist instructs a patient to move her lower teeth forward in relation to the upper teeth. This motion is termed as:
- Protrusion
- Retrusion
- Lateral deviation
- Occlusal position
Q9. Tests for the length of the hamstrings typically involve stabilisation of the uninvolved leg while raising the leg to be tested. It is important to stabilise the uninvolved leg because it:
- Prevents excessive posterior pelvic tilt and excessive flexion of lumbar spine
- Prevents excessive posterior pelvic tilt and excessive extension of lumbar spine
- Prevents excessive anterior pelvic tilt and excessive flexion of lumbar spine
- Prevents excessive anterior pelvic tilt and excessive extension of lumbar spine
Q10. A physical therapist consistently falls behind with his documentation due to an excessive patient load. The most appropriate action is:
- Discuss the situation with other staff (physical therapists)
- Ignore the situation and attempt to complete the documentation in a timely fashion
- Discuss the situation with immediate supervisor
- Discuss the situation with the Director of rehabilitation
