Rehabilitation and Therapy Physical Rehabilitation 1 — Questions and Answers
Question 1: Which muscle group is primarily targeted during closed kinetic chain exercises for knee rehabilitation?
- Quadriceps and hamstrings (Correct answer)
- Biceps and triceps
- Deltoids and rotator cuff
- Gastrocnemius only
Correct answer: Quadriceps and hamstrings
Closed kinetic chain exercises like squats engage the quadriceps and hamstrings together, promoting co-contraction and joint stability.
Question 2: What does RICE stand for in acute injury management?
- Rest, Ice, Compression, Elevation (Correct answer)
- Repeat, Improve, Correct, Exercise
- Relax, Integrate, Compress, Elevate
- Rest, Increase, Compress, Energize
Correct answer: Rest, Ice, Compression, Elevation
RICE (Rest, Ice, Compression, Elevation) is the standard first-line treatment protocol for acute musculoskeletal injuries to reduce pain and swelling.
Question 3: Which type of muscle contraction occurs when the muscle lengthens while producing force?
- Eccentric (Correct answer)
- Concentric
- Isometric
- Isokinetic
Correct answer: Eccentric
An eccentric contraction involves the muscle generating force while elongating, such as when lowering a weight slowly.
Question 4: A physical therapist uses manual traction on the cervical spine. What is the primary intended effect?
- Decompressing intervertebral discs and reducing nerve root pressure (Correct answer)
- Increasing cervical muscle bulk
- Strengthening ligamentous support
- Improving cardiopulmonary endurance
Correct answer: Decompressing intervertebral discs and reducing nerve root pressure
Cervical manual traction aims to separate vertebral segments to decompress discs and relieve nerve root impingement.
Question 5: What is the Borg Rating of Perceived Exertion (RPE) scale range?
- 6 to 20 (Correct answer)
- 0 to 10
- 1 to 100
- 0 to 20
Correct answer: 6 to 20
The original Borg RPE scale runs from 6 to 20, where 6 represents no exertion and 20 represents maximal exertion.
Question 6: Which gait phase occupies approximately 60% of the gait cycle?
- Stance phase (Correct answer)
- Swing phase
- Double support
- Terminal swing
Correct answer: Stance phase
The stance phase, when the foot is in contact with the ground, comprises approximately 60% of the normal gait cycle.
