Improving neurological deficits secondary to transverse myelitis using epidural spinal cord stimulation: illustrative cases

BACKGROUND Epidural spinal cord stimulation (eSCS) is canonically used for the treatment of intractable, chronic pain. Recent efforts have successfully utilized eSCS to improve neurological deficits in patients with spinal cord injury. However, there is a paucity of literature on the use of eSCS for demyelinating conditions, with no prior case reports examining eSCS among patients with transverse myelitis (TM). OBSERVATIONS Two patients with TM underwent eSCS and experienced improvements in motor function and bladder symptoms. The first patient exhibited enhanced motor strength in both lower extremities and no longer experienced leg spasms, increasing exercise capacity and decreasing their fall risk. The patient had reduced incontinence pad usage due to a regained ability to sense bladder fullness. The second patient also experienced improved motor scores, leading to enhanced motor functionality and independence. Furthermore, the patient observed reductions in urinary tract infections post-eSCS. Neither patient reported substantial improvement in bowel function following stimulation. LESSONS Improvements in motor functionality and bladder functioning are well-documented as factors that improve quality of life among paraplegic patients. Given the findings of the present case report, larger cohort studies examining the use of eSCS for demyelinating conditions, including TM, are warranted.
