Catastrophizing also has been implicated in mediating the relationship between pain and sleep disturbance. Not surprisingly, a randomized controlled study demonstrated the benefit of 8-week, Internet-delivered CBT in patients suffering from comorbid chronic pain, depression, and anxiety. Treatment significantly diminished pain catastrophizing, depression, and anxiety; maintenance of improvement was demonstrated after 1 year of follow-up. 31
Other behavioral and psychological approaches. Biofeedback, mindfulness-based stress reduction, relaxation training and diaphragmatic breathing, guided imagery, hypnosis, and supportive groups might play an important role as components of an integrated mind−body approach to chronic pain, 28,32,33 while also providing mood benefits.
Exercise. The role of exercise as a primary treatment of MDD continues to be controversial, but its benefits as an add-on intervention are indisputable. Exercise not only complements pharmacotherapy to produce greater reduction in depressive scores and improvement in quality of life, it might aid in reestablishing social contacts when conducted in a group setting—an effect that can be of great value in both MDD and chronic pain. 34
Exercise and restorative therapies provide several benefits for chronic pain patients, including:
improved pain control, cognition, and mood
greater strength and endurance
cardiovascular and metabolic benefits
improved bone health and functionality. 26,28,32,33,35
To achieve optimal benefit, an exercise program must be customized to fit the patient’s physical condition, level of fitness, and specific type of pain. 35 Preliminary evidence suggests that, beyond improvement in pain and functionality, exercise might reduce depressive symptoms in chronic pain patients. 36
Bottom Line Because pain and depression share common neurobiological pathways and clinical manifestations, similar strategies and agents are used to treat these conditions, including when they are comorbid. Use of antidepressants for treatment of chronic pain is a common practice. Long-term benefit of opioids is limited, although the risk of these drugs is high. Gabapentin and pregabalin decrease pain intensity and improve quality of life and function neuropathic pain. Non-drug approaches can be used as stand-alone, but are more commonly incorporated into a multimodal treatment plan or applied as an adjunct.
