RehaCom's new screening module

To recover cognitive function following a brain injury, cogntive rehabiliation training needs to be specific to the particular cognitive deficit.  Targeted cognitive therapy is an important instrument in the rehabilitation process.  Before starting the therapy with RehaCom, a diagnostic assessment of all brain functions is ideally made in order to pinpoint the impairment as well as determine which functions are still intact.

A common question we are asked is,

"We don't have access to a full neuropsychological test profile, so how do we know which are the best RehaCom training moduls to use?"

RehaCom screening

In recent years RehaCom has included an optional set of Screening Modules. With the latest release of the software, RehaCom now offers 10 screening modules to test cognitive functions.

The Screening modules provide their results iby making comparison with healthy people of the same gender and age. As a result of the testing, the system can then recommend RehaCom therapy with the specific therapy modules which will best fit the client‘s needs.

Then, a therapy plan is created to meet the client‘s specific needs, and specific goals are defined together with the client so that the therapy is likely to be as successful as possible.

RehaCom is designed as a therapy tool. As such, its primarly focus is on rehabilitation of cognitive impairments. In contrast to a complex neurospychological assessment, the screening tool just gives a "hint" about which training modules should be included based on an assessm according to the deviation from the norm.

Specially adapted screenings can help to identify suspected cognitive weaknesses or impairments. This area can be assessed with further specific diagnostic tools afterwards if necessary.

Impairments of vision, visual-spatial perception, and attention are common problems following a brain injury. Approximately 20–40% of patients with an acquired brain injury have visual problems, 61.7% of those patients have restrictions or losses in the visual field.

The ability to see is obviously a very important sensory function. Disorders affecting the visual field impact orientation and, depending on the degree of disturbance, have an effect on our everyday actions (e.g. searching and finding objects when eating or getting dressed, safely navigating a room without bumping into something, recognizing faces, reading the newspaper, watching TV, using the computer). The visual field is vitally important, especially when driving a motor vehicle.  Disorders of the field of view and visual field affect participation in many aspects of life and therefore require therapy and rehabilitation to improve the participation.

In the Campimetry screening, the field of vision can be examined binocularly or monocularly. Unlike the three-dimensional perimetry, campimetry is two-dimensional.
The client's task is to react to stimuli within his field of vision under fixation control.

Before beginning a screening parameters need to be adjusted, such as the size of the monitor, the distance between the monitor and the eyes, the size of the matrix, and the client's eyes. The client should be positioned in front of the monitor in a set distance, comfortable but fixed. To easily achieve this you can use our chin rest, which is available as an option.
During the screening,  the client's gaze should stay fixed on a point on the screen. To ensure this the client has to react to the point changing in shape and colour in irregular intervals.
In the test, stimuli appear in random intervals and on random places on the screen. Position and number of stimuli are calculated based on the parameters set in the beginning. Every stimulus and change of colour should be acknowledged as fast as possible by pushing the "answer" key.

Conclusion

Campimetry is the latest addition to the available Screening Modules available within RehaCom. Although not a substitute for exhaustive neuropsychological testing, these modules provide very effective guidance on which training modules should be used and provide a method of evaluating progress.
