INTRODUCTION The world's population is experiencing an increasing prevalence of depressive disorders. A comprehensive literature review identifies a schism between current medical interventions and the increasing prevalence. Current treatment paradigms warrant analysis. OBJECTIVE This manuscript theorizes an interdisciplinary team inclusive of physiotherapy as a standard would reverse the increasing prevalence. Physiotherapists' musculoskeletal expertise and biopsychosocial approach play a valuable role in mental health. METHODS A clinical narrative review of depression, including parallels with chronic pain, is provided as a substantive foundation. The review includes challenges in primary care as the gateway to mental health. Depression's underlying mechanisms, standard interventions, current theories, and future paradigms are explored. RESULTS A theoretical construct was formulated. This construct identified compromised emotion-regulation and self-efficacy as common dysfunctions that enables and perpetuates depression. Physical activity with cognitive reappraisals positively influences these common dysfunctions and improves general intervention outcomes. The psychologically informed physiotherapist is defined. Physiotherapists can provide functional interventions and cognitive reappraisals that address biopsychosocial needs and build resilience. CONCLUSION Individualized physical and functional activity that facilitate therapeutic alliance, functional improvements, cognitive reappraisals, emotion-regulation and self-efficacy delivered by a physiotherapist provide sustainable behavioral change and completes the interdisciplinary mental health team.
