About

A literature review was completed related to the topic of use of the Virtual Seating Coach (VSC) device with clients with Amyotrophic Lateral Sclerosis (ALS) with no results. The VSC components are FDA approved and Health Insurance Portability and Accountability Act (HIPPA) compliant, which have been used for many years by clinicians to achieve therapy goals of repositioning and best practice of utilizing power wheelchair seat functioning on a frequent basis. The VSC is typically not covered by insurance, but with clinical documentation, it has the potential for reimbursement. There is conflicting and vague information in the literature with regards to the prevalence/types of wounds and prevalence of pain in this population.

Full description

According to most literature, clients with ALS in general, get few pressure injuries. At this clinic, however, potentially due to the longer life expectancy of clients who choose tracheostomy with mechanical ventilation and a feeding tube, some clients do get pressure injuries. Also, many clients once they are sitting most of the day, whether in the wheelchair, recliner or bed, complain of discomfort and pain. Most clients will use or require a power wheelchair for mobility and positioning in the course of the disease process, and many will require it full time as symptoms progress. Generally, decreased sensation is not a symptom of ALS, but it is unknown why some people with ALS have pain and pressure injuries despite the intact sensation needed to cue repositioning.

It is best clinical practice to provide clients with ALS power wheelchairs that tilt, recline, and have leg elevation for maximal pressure management and to encourage repositioning to reduce the risk of skin breakdown/pressure injury as well as decrease pain. This study will study the effect of having an alerting/coaching system for training and reminders on performing pressure relief and repositioning for decreasing the number of pressure injuries as well as decreasing pain. The VSC also gives contextual cues to achieve a specific angle set-up by the clinician. Not only does the VSC provide alerts, but the client and clinician can observe and track the amount of time the chair is on and in what position.

Virtual Seating Coach

Active Comparator group

Description:

The Virtual Seating Coach is a context-aware reminding system that when set up by a clinician, directly benefits a user by reminding him or her to change position with the chair's power seating function.. Regular position changes increase independent function, reduce the risk of pressure ulcers, manage pain, and reduce swelling.

Treatment:

Behavioral: Virtual Seating Coach

Non Virtual Seating Coach

No Intervention group

Description:

power wheelchairs that tilt, recline, and have leg elevation for maximal pressure management and to encourage repositioning to reduce the risk of skin breakdown/pressure injury as well as decrease pain.
