AI in Physical Rehabilitation Quiz

Answers and explanations appear as you take the quiz.

1. What does 'markerless motion capture' allow in rehab?
   • Tracking movement using ordinary cameras and pose estimation
   • Capturing motion only with physical reflective markers
   • Measuring blood pressure
   • Reading a patient's thoughts
2. What is the main idea behind 'assist-as-needed' rehabilitation robots?
   • The robot does all the work for the patient
   • The robot supplies only enough help so the patient does as much as possible
   • The robot replaces the patient's limbs permanently
   • The robot only records data and never assists
3. Wearable inertial measurement units in rehab are mainly used to:
   • Stream music during exercise
   • Charge the patient's phone
   • Quantify metrics like range of motion and gait symmetry
   • Translate languages
4. Which task is a pose-estimation model performing in a rehab app?
   • Encrypting medical files
   • Scheduling clinic appointments
   • Printing prescriptions
   • Locating body keypoints to compute joint angles
5. A predictive model in rehabilitation might be used to:
   • Flag patients likely to drop out of therapy
   • Choose the clinic's wall color
   • Set the building's thermostat
   • Replace the therapist's license
6. Why is smartphone-camera rehab significant for access?
   • It only works in hospitals
   • It can bring guided rehab into patients' homes
   • It requires a research lab
   • It eliminates the need for any exercise
7. After pose estimation extracts movement features, what can a classifier score?
   • An unrelated patient attribute not visible in the video
   • The cost of a therapy session
   • Whether the exercise movement appears correct
   • The material of the camera lens
8. How can an adaptive digital rehabilitation platform use a patient’s performance?
   • Replace the therapist’s clinical assessment permanently
   • Change the patient’s diagnosis without review
   • Disable the exercise whenever a movement is completed
   • Adjust exercise difficulty as performance changes
