The session will outline the concept of utilising a functional capacity evaluation (FCE) process for mental health, cognitive and neurodiversity conditions to assist in the development of safe and sustainable return to work programmes. As occupational therapists are trained to assess and treat physical, mental and cognitive health conditions, the occupational therapists’ FCE design can be adapted from the traditional physical assessment to encompass occupational performance measures including time standards for psychological and cognitive conditions. Learning outcomes: - Understanding the benefits of using FCEs in assisting individual’s to return to work and how this is used with people with mental health, cognitive health and neurodiverse conditions - Understanding how FCEs and time standards impact on measuring and improving occupational performance. - Understanding how this translates into return to work and vocational rehabilitation programme designs and outcomes.
