This presentation will discuss associated reactions (ARs) of the arm and the impact these involuntary arm movements have on people with acquired brain injury. The many negative effects of ARs will be explored looking at both the physical and psychological sequelae.

The challenges that currently exist in the field of ARs will be highlighted, with a primary focus on the need for clinicians to be able to accurately identify ARs and assess changes in response to treatment. Relevant literature will be outlined, emphasising the need for a new gold-standard, clinically feasible and functional outcome measure of ARs.
