This book examines the occupational therapy paradigm (its focal viewpoint, core constructs, and values) as well as the role of complexity/chaos theory as a scientific framework for occupational therapy research and practice. Unlike other current OT texts, this book uses clinical case examples to illustrate application of proposed changes to make procedures consistent with the latest Occupational Therapy Practice Framework. The reader walks away with a clear grasp of the theoretical principles guiding his or her treatment interventions, the explanations behind those principles, and the applicable intervention for said techniques and procedures.
