Rehabilitation Engineering MCQ

Correct Answer: B – Accommodation of user needs and environment changes
Explanation:
In rehabilitation device design, adaptability refers to the device’s ability to adjust according to the user’s evolving physical abilities, therapy progress, and environmental conditions. This means the device can be modified in terms of size, support, resistance, or functionality to suit different stages of recovery or varying user requirements. For example, an adjustable wheelchair or prosthetic limb that can be fine-tuned for comfort, mobility, and daily activities demonstrates adaptability. It is not just about multiple functions (A) or fixed properties (C); the key is responsive adjustment to changing user needs and contexts.

Q36. The principle of "allowance for recovery from errors" improves:

Correct Answer: B

Allows users to manage mistakes safely.

Q37. Why is adaptability important in rehabilitation devices?

Correct Answer: A

Correct Answer: Option A – Allows the device to meet changing user needs Explanation: Adaptability is a crucial feature in rehabilitation devices because users’ physical abilities, therapy goals, and recovery stages often change over time. A device that can adjust its settings, configuration, or functionality ensures that it continues to provide appropriate support, resistance, or assistance as the user progresses. For example, an adaptable exoskeleton or orthotic can modify its movement range or support level to match improved strength or mobility. Without adaptability, devices may become less effective, limit rehabilitation outcomes, or require frequent replacements, making adaptability essential for long-term, personalized therapy and improved patient independence.

Correct Answer: B

Music and dance therapy improve mental health.

Q39. Which type of prosthesis uses muscle bioelectrical signals for control?

Correct Answer: B

Myoelectric prostheses use muscle signals.

Q40. Which is NOT a role of biomedical engineer in rehabilitation?

Correct Answer: C

Counseling is done by psychologists.
