    Area of Science:

    • Rehabilitation Engineering
    • Assistive Technology
    • Biomechanics

    Background:

    • Polio survivors often experience significant motor impairments, including paralysis.
    • Limited upper limb function restricts independence in daily activities like self-feeding.
    • Existing assistive devices may not fully address the complex range of motion needs for individuals with paralysis.

    Purpose of the Study:

    • To design and describe an innovative arm balancer for a polio victim with paralysis.
    • To restore functional arm movement for independent self-feeding.
    • To provide power-assisted control for enhanced mobility.

    Main Methods:

    • Development of a custom arm balancer system.
    • Integration of a mechanism for free horizontal plane movement.

  • Incorporation of a user-controlled power assistance system for vertical motion.

    • Main Results:

    • The designed arm balancer allows the patient to swing their affected arm freely in a horizontal plane.
    • Vertical arm movement is enabled with user-controlled power assistance.
    • The device facilitates improved reach and manipulation for self-feeding.

    Conclusions:

    • The developed arm balancer effectively addresses the needs of a polio patient with paralysis.
    • Assistive technology can significantly enhance independence and quality of life for individuals with motor impairments.
    • This design offers a potential solution for restoring upper limb function in similar patient populations.
