KINOVA® Dynamic arm support O110 User Guide 3
Introduction
What is an arm support?
A dynamic arm support is an assistive technology product that helps people with limited arm and
shoulder function to move their arms and hands more easily. The device has a number of potential
benefits.
A dynamic arm support is an assistive technology product which allows people with limited arm and
shoulder function to move their arms and hands more freely. This facilitates many kinds of daily activities,
such as using a computer or eating.
The arm support can also be used by people without limits in arm or shoulder function as an ergonomic
support for performing repetitive tasks in the workplace.
Arm supports use spring mechanisms to compensate for the weight of the user’s arm. Without having to
expend energy to hold up the weight of the arm, people with limited function can move their arm more
easily. This can help maintain the muscles and joints of the user and improve quality of life by allowing
users to be more independent.
Use of arm support and normal use definition
The arm support is designed for an intended scope and environment of use. There are some
limitations that apply, and potential contraindications for use. A health professional can help
determine if the device is right for a given user.
Intended scope of use
The arm support device does not take over any arm function. The user makes the movements himself,
using his own strength. The device only supports part of the weight of the arm, making it easier to perform
the movement. The device supports the arm through all movements within a three dimensional region.
Actions performed while using the arm support are the responsibility of the user.
Limitations
The arm support is intended to be used to help support arm movements during typical, everyday activities
at home, in public, or in a typical office environment. The arm support is not intended to be used while
driving an automobile or operating other heavy equipment, or for carrying out tasks involving dangerous
tools or materials.

• Presentation of musculoskeletal or joint injuries having a functional link with mobility of the upper
limb
• Absence or insufficient level of muscle tone or motor control
• Presentation of proprioception problems
