Chronic back and neck pain. Whiplash. Fibromyalgia. Carpal tunnel syndrome. Intractable headaches. Depression. Anxiety and posttraumatic stress. Concussion. More than ever, the term workplace disabilities is synonymous with greater clinical and case management complexity and escalating personal, social, occupational and economic cost. Complex illnesses and injuries that defy a traditional medical management model continue to baffle medical, mental health, rehabilitation, compensation, corporate, and legal professionals despite new advances in diagnosis, prevention, and rehabilitation. The Handbook of Complex Occupational Disability Claims: Early Risk Identification, Intervention and Prevention cuts through the confusion by integrating current theories and findings into a state-of-the-art tool for critical thinking, decision making, and effective practice. A book that synthesizes so many diverse viewpoints has the potential to influence both policy and practice across disciplines and cut through politicization of these still poorly understood conditions with evidence. The Handbook is important reading for all clinicians, professionals, and members of rehabilitation and disability management teams, across healthcare, occupational and compensation settings.
