At C5, grasp and finger extension are typically absent, limiting direct manipulation of small input devices. However, head and neck control are often preserved, making head-controlled pointing a strong first-line access strategy. Pairing head pointing with dwell-click or a light-action switch (e.g., cheek, temple) enables full cursor control and clicking without finger movement. Trials should assess calibration stability, pointer accuracy, visual strain, and endurance across real tasks (LMS navigation, document editing). A standard mouse (A) is not feasible without finger function; a keyguard assists typing accuracy but does not solve pointing. A strapped stylus (C) can create awkward wrist postures and may be inefficient given absent finger control. Foot control (D) is unsuitable if lower limb function is compromised or positioning is impractical in classroom seating. Begin with head pointing, but keep alternatives (voice recognition, on-screen keyboard with scanning, switch access) on the trial list. Objective metrics—task completion time, error rates, and perceived exertion—should guide the ultimate selection.
