Which device would best allow interaction with a computer, television, and telephone for a C1 AIS A SCI patient who is ventilator-dependent and has no upper extremity function?

Which device would best allow interaction with a computer, television, and telephone for a C1 AIS A SCI patient who is ventilator-dependent and has no upper extremity function?

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

Answer: (C)

When a person has a high cervical spinal cord injury (like C1 AIS A), is ventilator-dependent, and has no usable upper-extremity function, the key need is a single way to control multiple devices without using the hands. An environmental control unit (ECU) that accepts sip-and-puff or voice activation provides that capability. The ECU acts as a central hub that can operate a computer, television, and telephone through input methods that require little to no hand movement. Sip-and-puff lets the user switch and select commands by blowing or sucking on a mouthpiece, which is reliable even with complete loss of hand function. Voice activation offers hands-free control via speech, which can cover many common actions once set up. Many ECU systems are designed to integrate these inputs across devices, giving practical, accessible control in daily activities. The other options don’t meet this need as effectively. A tenodesis splint relies on some usable finger or hand function to grip, which isn’t available here. A universal cuff provides support for holding objects but still requires hand or arm control to use, so it wouldn’t enable independent device control. Mobile arm supports assist with arm positioning or residual movements but don’t provide a direct, multisystem input method for computer, TV, and phone control.
