About this study

Parkinson's disease (PDS) is a syndrome characterized by tremor, bradykinesia, rigidity, and postural disturbances. Causes include Parkinson's disease (PD), multiple system atrophy (MSA), progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD). Non-motor symptoms of PDS, such as neurogenic orthostatic hypotension (nOH), have received more intensive research due to their greater disabling potential compared to motor symptoms. In patients with PD and MSA, nOH can lead to intolerance to medications such as levodopa, significantly increasing the risk of falls, accelerating cognitive decline, and increasing the risk of all-cause mortality. However, conventional pharmacological treatments (such as midodrine, droxidopa, and fludrocortisone) and non-pharmacological approaches (such as compression abdominal bands, elastic stockings, and deep brain stimulation) for non-motor symptoms such as nOH have numerous limitations, including short-term efficacy, uncertain efficacy, and side effects. Therefore, exploring new non-pharmacological treatments to improve nOH and delay disease progression in patients with PDS is crucial for improving their quality of life and prognosis.

Spinal cord stimulation (SCS), including invasive (epidural) spinal cord stimulation (eSCS) and non-invasive (transcutaneous) spinal cord stimulation (tSCS), is a novel neuromodulatory technique with clinical applications in a variety of neurological diseases. Currently, several small-sample studies have suggested the potential efficacy of SCS for nOH caused by spinal cord injury (SCI). This study innovatively proposes the use of eSCS and tSCS to improve nOH and related clinical symptoms in patients with PDS. A prospective, single-center, randomized, controlled clinical trial is planned to compare the efficacy of invasive and non-invasive SCS in treating nOH, thereby providing new insights for the effective treatment of PDS.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Epidural spinal cord stimulationDevice

    Epidural spinal cord stimulation (eSCS) 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 fibres 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.

  • Transcutaneous spinal cord stimulationDevice

    Transcutaneous spinal cord stimulation (tSCS) is a non-invasive treatment that improves symptoms by stimulating spinal nerves with pulsed electrical currents via electrodes placed at corresponding spinal cord segments. The tSCS system consists of an electrical pulse stimulator, wires, and conductive patches.

Study groups in NCT07322458
Study groupRoleWhat they receive
Epidural spinal cord stimulation (eSCS) implantationExperimentalPhase I: (1) Spinal cord segment is selected as the puncture location according to the patient's symptom and the condition of the patient's spinal cord. Percutaneous puncture is performed under X-ray guidance. One or two electrodes are placed in the patient's epidural cavity, and the electrode position is adjusted intraoperatively and by the patient's feedback of the current stimulation position until the current can cover the entire area. (2) An extension lead is connected, an external temporary stimulator is attached, and the patient decides whether to proceed to full implantation in phase II after 7-10 days of phase I testing experience. 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.
Receives: Device: Epidural spinal cord stimulation
Transcutaneous spinal cord stimulation (tSCS) applicationExperimentalAfter completing the necessary assessments and informed consent procedures, subjects will undergo device installation and seated programming. The cathode of the tSCS device will be placed at the level of the lower thoracic spinal cord via a hydrogel adhesive electrode, and the anode will be placed bilaterally at the iliac crest via a hydrogel adhesive electrode. During seated programming, subjects will undergo continuous non-invasive blood pressure monitoring and a medication-free head-up tilt test (TTT). If subjects demonstrate a satisfactory clinical response during the testing phase (defined as an increase in systolic blood pressure of more than 15-20 mmHg with stimulation on compared to the off state), they will enter regular tSCS therapy during the treatment phase.
Receives: Device: Transcutaneous spinal cord stimulation

Questions about this trial

What is this clinical trial studying?

A study testing Epidural spinal cord stimulation and Transcutaneous spinal cord stimulation in people with Parkinsonism, run by Ruijin Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 9 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Jun LIU, MD, PhD (021-64370045, jly0520@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change of blood pressure from baseline to immediately post-operation or post transcutaneous stimulation (time frame: Immediately post surgery or post transcutaneous stimulation). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jan 2026.
