Psychological, Behavioral, and Rehabilitation Approaches to Pain
Behavior and rehabilitation are active treatments
Psychological and rehabilitative care is not a consolation prize; it is core treatment for chronic pain. Explain the fear-avoidance model: pain leads to catastrophizing, fear, avoidance, deconditioning, and disability. Cognitive behavioral therapy targets unhelpful thoughts and behaviors; acceptance and commitment therapy builds values-based activity; mindfulness and relaxation reduce arousal. Pain neuroscience education helps patients understand that persistent pain reflects sensitized processing rather than ongoing tissue damage. Graded activity and graded exposure restore function without triggering flares. Physical therapy, exercise, sleep hygiene, and vocational rehabilitation are essential partners.
Interdisciplinary care - one team with shared goals, communication, and a biopsychosocial formulation - outperforms parallel referrals. Screen for depression, anxiety, PTSD, and suicide risk; treat substance use disorders concurrently. Traps include telling patients the pain is “all in your head,” recommending bed rest, setting goals of complete pain elimination, and failing to address sleep and mood. Also avoid starting an intensive program before the patient understands the rationale; engagement predicts benefit.
Worked example: a patient with chronic low back pain and high catastrophizing has stopped walking. Rather than rest, prescribe a graded walking plan starting below the flare threshold, add pain neuroscience education and CBT, and set a functional goal such as walking to the mailbox and back.
Rule of thumb: function first; pain relief often follows activity, not the reverse.
