Which device would be most appropriate for a patient with no usable upper extremities to operate environmental controls (like a computer or TV)?

• A. Tenodesis splint
• B. Universal cuff
• C. Environmental control unit with sip-and-puff or voice activation
• D. Mobile arm supports

Answer: (C)

When there’s no usable upper-extremity function, you need an input method that doesn’t rely on hands to control devices. An environmental control unit that uses sip-and-puff or voice activation provides exactly that kind of access. Sip-and-puff uses a mouthpiece connected to air-pressure switches, so the person can blow or suck to issue commands and control a computer or TV. Voice activation relies on spoken commands picked up by a microphone, with the device executing those commands. Both options let the person operate environmental controls independently without any hand or arm movement, which is why they’re the best fit in this scenario. Tenodesis splint and universal cuff are designed to help grasp or hold objects when there’s some hand or arm function available, and mobile arm supports assist limb positioning or movement to reach. They don’t enable independent control of environmental devices when no usable upper-extremity function exists, so they’re not as suitable in this situation.
