Nonlinear dynamics systems theory, also referred to as chaos theory, is infiltrating the biomedical and social sciences, including the practice of occupational therapy. Consequently, the Neuro-occupation model has emerged for the treatment of different illnesses, in which a therapist strives to apply the benefits of this theory. This model provides occupational therapists with a method of anticipating the natural flux between underlying or hidden order and chaos in occupations, which allows individuals to function at their highest level. These occupations typically involve the interaction of numerous variables over time. By considering a nonlinear dynamics approach in illnesses such as alcoholism, occupational therapists may understand how meaningful occupations serve as a catalyst to facilitate change, which may assist in better understanding the effect of the therapeutic relationship with the clients they serve. This paper explains the nonlinear dynamics of the interventions in a single case study on alcoholism using the Neuro-occupation model.
