About this study
The goal of this clinical trial is to learn if the cueStim device can reduce the duration of freezing of gait (FoG) that occurs in patients with Parkinson's Disease. The study will compare two modes of operation of the cueStim device; both modes of operation use the same wearable device. The purpose of the study is to compare how the two modes affect symptoms across study participants. Because this is a research study, it is not yet known whether either mode reduces symptoms.
Participants will:
- Be randomized to one of the two modes available on the cueStim device
- Wear the device for 4 weeks as they go about their daily life
- Complete daily diary entries to document symptoms, falls and overall experience
- Check-in with the clinical site throughout participation
- Complete a final follow-up visit
Read the detailed description
This is a prospective, randomized, double-blind, parallel group, multicenter, pivotal clinical trial to validate the use of cueStim for reduction of duration of FoG in Parkinson's patients.
Enrolled subjects will be randomized 1:1 to two different modes of treatment. All subjects will be blinded to the study hypothesis. The clinician will not be blinded; however, specialists who will evaluate the outcome will be blinded. Enrolled subjects will be provided with training on the device during a clinic visit, and phone support is available throughout the home treatment duration.
Study procedures / visits consists of:
- In-clinic Screening visit to ensure eligibility
- Baseline visit for device setup and training (may be combined with screening visit)
- "Home" (unsupervised at and out of the home) use of the device for four (4) weeks) as the patient goes about their daily life
- End-of-treatment Follow-up visit
The primary objective of this clinical investigation is to determine if one mode of treatment demonstrates superiority after four weeks of device use, in reducing the duration of FoG, while the device is being worn by patients with PD receiving medication.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CueStimDevice
Enrolled patients will be assigned to one of two modes and will be blinded to their assignment. The Device will be worn for four weeks throughout the patient's daily life. The patient will complete daily diary entries, periodically check in with the clinical staff, and complete questionnaires related to the impact of freezing of gait and Parkinson's Disease on daily life and function.
| Study group | Role | What they receive |
|---|---|---|
| First mode of cueStim | Active comparator | The first, unidentified mode delivers electrical stimulation to the legs to improve gait (i.e., reduce Freezing of Gait [FoG]) of patients with Parkinson's disease (PD).
There are also 2 electrodes which connect the stimulators to the subject. Stimulators are attached to the thigh of each leg. The stimulators deliver sensory electrical stimulation (sES), a non-adaptive rhythmic cueing strategy consisting of a continuous series of biphasic electrical stimulation bursts, in an alternating rhythmic manner scaled to the patient's stride rate. Stimulation is customized to each patient prior to first-time use via a Clinician Tablet Controller. The Tablet Controller is used to program and to adjust device stimulation settings over time. The Stimulators' on-board electronics sense when the patient is sitting, has stopped walking or is attempting to walk and delivers stimulation only when the patient is actively walking or attempting to walk. Receives: Device: CueStim |
| Second mode of cueStim | Active comparator | The second, unidentified mode is a modified version of the cueStim stimulator which uses a different mode of stimulation. Receives: Device: CueStim |
What is being measured
The primary outcome is the main question the study is designed to answer.
Demonstrate Superiority
The main goal of this study is to determine whether one mode of the cueStim device works better than another. After four weeks of use, it will be compared how well each mode reduces the duration of freezing of gait in patients with Parkinson's Disease who are taking medication, while they are wearing the device.
Measured: From enrollment to the end of treatment at 4 weeks
