This assessment- as the name suggests – assesses global physical, cognitive and emotional functional capacity that one might need to perform a specific job or any job in general. Capacity is the key word here –a capacity assessment measures how much or how long one can perform a certain function. It also takes into account the effect of pain and fatigue on all the realms of function. This type of assessment is helpful to determine if a person who has physical impairments, as well as cognitive and/or emotional issues related to pain, brain injury and/or psychological disorder, can do their job or any job. It can also help to determine and provide opinion on what accommodations or adaptations they might need to succeed.
