- Patients with significant cognitive impairment (Mini-Mental State Exam < 24) or inability to complete the questionnaire independently.
- Presence of anatomical abnormalities or other lesions of the spine that interfere with electrode implantation
- Dysarthria, swallowing difficulties, orthostatic hypotension from other causes not related to MSA.
- Critically ill or unstable vital signs.

Intervention / Treatment |
---|---|
Experimental: Spinal cord stimulation(SCS) implantation
Phase I:
Phase II: The complete SCS system is implanted under local anesthesia or epidural anesthesia after successful testing. A subcutaneous capsular bag is usually created in the lower abdomen and the implanted electrodes are connected to the pulse generator through a connecting wire in the subcutaneous tunnel. |
Spinal cord stimulation (SCS) is a very thin electrode implanted in the dorsal epidural space of the spinal cord to improve the patient's symptoms by stimulating the spinal nerves with pulsed electrical currents, which attenuate or enhance the flow of nerve impulses from the periphery to the central system, i.e., stimulating thick fibers to achieve therapeutic results.
SCS system consists of three components: an electrode implanted in the epidural space of the patient's spinal cord, a stimulator implanted subcutaneously in the abdomen or buttocks that delivers electrical impulses, and an extension cord that connects the two.
