    A novel computer system enables communication for a patient with severe paralysis. Using a thumb-controlled Morse code interface, the system translates signals into text and computer commands, restoring environmental control.

    Area of Science:

    • Biomedical Engineering
    • Assistive Technology
    • Neurorehabilitation

    Background:

    • Brainstem infarction can lead to severe motor deficits, including loss of speech and limb control.
    • Effective communication and environmental control are critical for quality of life in individuals with high-level spinal cord injuries or neurological damage.
    • Existing assistive technologies may not adequately address the complex needs of patients with extremely limited motor function.

    Purpose of the Study:

    • To develop a computer-based communication and control system for a quadriplegic patient with preserved cognitive function.
    • To enable communication and environmental interaction for an individual with profound motor impairment following a brainstem infarction.
    • To design an accessible interface utilizing residual motor control.

    Main Methods:

    Related Experiment Videos

    • Developed an arm brace to support the patient's right hand and thumb.
    • Integrated two switches controlled by the thumb to generate Morse code signals.
    • Created an interface to translate Morse code into ASCII characters and computer control functions for personal computer access.

    Main Results:

    • The system successfully translated Morse code signals into text for communication.
    • The patient could utilize the system to control various functions of a personal computer.
    • The device facilitated environmental control to a significant extent for the patient.

    Conclusions:

    • A customized computer-based system using Morse code and a thumb-operated interface can restore communication and environmental control for severely paralyzed individuals.
    • This technology offers a viable solution for patients with brainstem infarction and limited motor function.
    • The developed system highlights the potential of adaptive technology in improving independence and quality of life.
