Students are introduced to diseases, disorders and impairments as barriers to occupational performance and participation in society across the lifespan. This includes an introduction to the principles, processes, conditions and cultural factors that affect a person's physical and mental health, and general wellbeing. The focus is on facilitating learning about these conditions from an occupational perspective and how they affect a person’s ability to participate and engage in daily activity. Also considered are the sensitivities needed by occupational therapists when working with specific client populations.
