FREE Assistive Technology Professional (RESNA) Questions and Answers
An individual can link EADL devices in several different ways. The least valuable item for various uses is:
Explanation:
Direct wiring is the least practical way to connect EADL devices for multiple use.
Direct wiring involves physically connecting each device to the control unit using wires, which can be time-consuming, labor-intensive, and difficult to modify or expand. This method is best suited for situations where there are only a few devices to control and the setup is not likely to change frequently.
What is the optimum position for a person's wrists and hands when using a keyboard for computer use or typing to lessen the stain from repetitive vital presses?
Explanation:
The best position for the person's wrists and hands when using a keyboard for typing is in a neutral position.
A neutral position means that the hands, wrists, and forearms are in a straight, neutral line, and not bent up, down, or to the sides. This helps to reduce the strain on the muscles and tendons in the hands and arms during repetitive motions of keying.
When choosing control interfaces for the user, the ATP decides to continue the evaluation using the technique below based on data gathered from the needs identification and physical-sensory components of the evaluation process:
Explanation:
The ATP (Assistive Technology Professional) may decide to pursue further evaluation using either direct selection or indirect selection interfaces when selecting control interfaces for the user.
Direct selection interfaces allow the user to directly interact with the control interface by touching or pointing to the desired control. This type of interface can be suitable for users who have good hand control and coordination.
Although results and advantages will differ, each intervention's main objective is to:
Explanation:
The overall goal of every intervention, regardless of the specific intervention or the individual's condition, is to maximize the individual's function.
Function refers to a person's ability to perform activities of daily living, such as self-care, mobility, communication, and participation in social, recreational, and vocational activities.
In motorized wheelchairs, the Sip and Puff switch array is an illustration of:
Explanation:
The Sip and Puff switch array utilized in power wheelchairs is not an example of Latch control.
Latch control typically refers to a type of control interface where the user activates a switch or button to turn a device on or off, and the device remains in that state until the switch is activated again to change the state.
Alternative keyboards for natural selection include the following, with the following exceptions:
Explanation:
Row Column Scanning and Matrix are not examples of alternative keyboards for direct selection.
Row Column Scanning and Matrix are scanning methods used with switches, where the user activates one or more switches to scan through rows and columns of options until the desired option is highlighted, and then activates a switch to make the selection. These methods are typically used by individuals with physical disabilities who have limited or no hand control.
