Considerations for the use of assistive technology in patients with impaired states of consciousness.

While there is limited literature addressing the application of assistive technology in patients in persistent vegetative state (PVS) and minimally conscious state (MCS), it is believed that it can assist with the assessment, diagnosis and treatment as well as management of these patients. The use of technology to assist in PVS and MCS is mostly limited to the application of simple binary switch devices to determine whether a motor response is consistent or otherwise. However, the application of such technology is often undermined due to a lack of established protocols for use by the multidisciplinary team (MDT), as well as a lack of available technical resources. Therefore the ongoing development of assessment instruments as well as effective outcome measures used by an MDT is imperative. This article aims to discuss some key aspects to consider in the use of assistive technology when assessing and treating people in impaired conscious states. Possible considerations and suggestions will be discussed through this paper and a case study will be used to demonstrate some of these interventions.
