An assistive equipment controller for quadriplegics.

G Schmeisser, W Seamone

    The Johns Hopkins Medical Journal
    |September 1, 1979
    PubMed
    Summary

    A modified joystick, now a chin-operated control, empowers individuals with quadriplegia to independently operate assistive devices like electric wheelchairs and robotic arms.

    Area of Science:

    • Rehabilitation Engineering
    • Assistive Technology
    • Biomedical Engineering

    Background:

    • Joysticks are standard controls for electric wheelchairs and model aircraft.
    • Quadriplegia, particularly high-level spinal cord injuries, severely limits mobility and device operation.
    • Existing assistive devices often require attendant assistance or specialized controls.

    Purpose of the Study:

    • To develop an inconspicuous and versatile control system for individuals with high-level spinal cord injuries.
    • To enhance independence and expand the range of operable assistive devices for quadriplegics.
    • To adapt joystick technology for alternative control methods.

    Main Methods:

    • Modification of traditional joystick design.
    • Development of a chin-operated control interface.
    • Integration of the control system with electric wheelchairs and other assistive technologies (e.g., robotic arms, environmental controls).

    Main Results:

    • An inconspicuous chin-operated control was successfully developed.
    • This control enables quadriplegics to operate electric wheelchairs independently.
    • The system also facilitates the operation of advanced assistive devices, including robotic arms and environmental controls.

    Conclusions:

    • The chin-operated control significantly enhances independence for individuals with high-level spinal cord injuries.
    • This innovative assistive technology expands functional capabilities beyond electric wheelchair operation.
    • Further development of integrated systems promises greater autonomy for users with severe physical disabilities.
