Stiff-Person Syndrome (SPS) is a rare neurologic disorder characterized by severe and progressively worsening muscle stiffness and rigidity. SPS can be very painful due to unpredictable muscle spasms which can be triggered by various stimuli, such as noise, touch, or emotional experiences. There is thought to be an autoimmune component to the disorder. We present the case of a 59-year-old woman diagnosed with SPS who appears to have experienced a dramatic reduction in her symptoms after being treated with Low-Dose Naltrexone (LDN). Prior to this treatment regimen, she had tried many treatments with only limited derived benefit. She was started on LDN and after 6 weeks, reported reductions in pain, anxiety, depression, agoraphobia, and muscle tightness. Upon multiple follow-ups, leading up to 12 months, she continually displayed reduced symptoms and improved quality of life. We conclude that LDN may have some utility in treating and managing the symptoms of SPS. We hypothesize that this may be possible due to LDN operating via anti-inflammatory pathways as well as acting as an opioid antagonist. We assert that further research as it relates to LDN and SPS in addition to other chronic pain conditions is warranted.

Chronic pain is often managed using a multidisciplinary, biopsychosocial approach. Interventions targeting the biological, psychological, and social aspects of both the patient and the pain have been demonstrated to provide objective and subjective improvement in chronic pain symptoms. The mechanism by which pain attenuation occurs after these interventions remains to be elucidated. While there is a relatively large body of empirical literature suggesting that functional and structural changes in the peripheral and central nervous systems are key in the development and maintenance of chronic pain states, less is known about changes that take place in the nervous system as a whole after biopsychosocial interventions. Using as a model the unique case of Mr. S, a patient suffering with chronic pain for 22 years who experienced a complete resolution of pain after a lucid dream following 2 years of biopsychosocial treatments, we postulate that central nervous system (CNS) reorganization (i.e., neural plasticity) serves as a possible mechanism for the therapeutic benefit of multidisciplinary treatments, and may set a neural framework for healing, in this case via a lucid dream.
