CMT CMT Therapeutic Exercise & Rehabilitation 2 — Questions and Answers
Question 1: The Cybex isokinetic device measures muscle performance at:
- Variable resistance with constant speed
- Constant speed of movement (fixed angular velocity) (Correct answer)
- Constant resistance regardless of speed
- Fixed load through a full range of motion
Correct answer: Constant speed of movement (fixed angular velocity)
Isokinetic devices maintain a constant angular velocity while accommodating resistance to the force produced, allowing safe maximum effort throughout ROM.
Question 2: A patient recovering from rotator cuff repair is in Phase 1 (0–6 weeks). Which exercise is most appropriate?
- Full active resisted shoulder elevation
- Pendulum (Codman) exercises and passive ROM within protocol limits (Correct answer)
- Bench press with light weights
- Overhead throwing program
Correct answer: Pendulum (Codman) exercises and passive ROM within protocol limits
Early post-op rotator cuff rehab uses pendulum exercises and passive ROM to prevent adhesions while protecting the surgical repair.
Question 3: Which of the following best describes 'neuromuscular re-education' as a rehabilitation goal?
- Rebuilding muscle bulk lost during immobilization
- Restoring normal movement patterns and motor control through sensory and motor retraining (Correct answer)
- Eliminating all pain before initiating movement
- Training fast-twitch fibers for explosive power
Correct answer: Restoring normal movement patterns and motor control through sensory and motor retraining
Neuromuscular re-education restores proper movement patterns, proprioception, and motor control that are disrupted by injury or disuse.
Question 4: In the rehabilitation of a patient with anterior knee pain (patellofemoral syndrome), a key exercise strategy is to:
- Avoid all quadriceps strengthening for 8 weeks
- Strengthen hip abductors and external rotators to reduce dynamic valgus (Correct answer)
- Focus exclusively on terminal knee extension to isolate VMO
- Apply RICE protocol indefinitely without progression
Correct answer: Strengthen hip abductors and external rotators to reduce dynamic valgus
Strengthening hip abductors and external rotators reduces femoral internal rotation and adduction, decreasing patellofemoral joint stress.
Question 5: The Rate of Perceived Exertion (RPE) Borg scale ranges from:
- 0 to 5
- 0 to 10
- 6 to 20 (Correct answer)
- 1 to 100
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: A CMT should discontinue exercise and reassess when a patient reports which symptom during rehabilitation?
- Mild muscle soreness beginning 24 hours after exercise
- Sharp joint pain or dizziness during the exercise session (Correct answer)
- Slight fatigue after completing the prescribed sets
- Muscle warmth and mild redness after sustained effort
Correct answer: Sharp joint pain or dizziness during the exercise session
Sharp joint pain or dizziness during exercise are red flag symptoms requiring immediate cessation and reassessment.
