Effectiveness of Intrathecal Baclofen for Intractable Stiffperson Syndrome: a Case Report.
BACKGROUND: Intrathecal baclofen is considered an adjuvant therapy for patients with intractable spasms due to stiff-person syndrome. There is increasing evidence to support the use of intrathecal baclofen in the management of symptomatic stiffperson syndrome, with improvement in function.
CASE REPORT: A 38-year-old woman with stiff- person syndrome initially presented to inpatient rehabilitation for intractable muscle spasms. The symptoms made her non-ambulatory and limited her tolerance to wheelchair use for mobility. The patient underwent up-titration of oral baclofen and diazepam, with concurrent intravenous immunoglobulin cycles, leading to transient symptom relief. She agreed to explore intrathecal baclofen therapy. An initial trial of a single bolus of 50 μg intrathecal baclofen resulted in a significant decrease in spontaneous spasms, enabling modified independence in transfers and ambulation. The patient was subsequently implanted with a permanent intrathecal delivery system. To date, the intrathecal baclofen had been titrated to 186 μg per day with simple continuous delivery. The patient was weaned off oral baclofen. She attained complete functional independence with ambulation without the need for assistive devices, and has had no lasting post-procedural complications to date.
CONCLUSION: This case report adds to the increasing evidence of cases of refractory stiff-person syndrome managed successfully using intrathecal baclofen therapy.
