Steadi-3 Plus
Stabilise Your Hands. Reclaim Your Freedom.
The Steadi-3 Plus is a revolutionary assistive device that reduces hand tremor. It is based on proven magnetic vibration absorber technology to stabilise buildings against earthquakes.4 Like a see-saw you’d see in a park, the vibration disk moves in the opposite direction to your tremor, providing stability.
The Steadi-3 Plus is a battery-free anti tremor glove using passive magnetic stabilisation to counteract tremor without charging, electronics, or setup. It is designed for Essential Tremor and the action-tremor component of Parkinson’s Disease. As a wearable tremor device, it has been clinically evaluated: 84% of users in a placebo-controlled study showed improved tremor control versus no device, and 70% showed improvement over a placebo hand tremor glove based on blinded neurologist assessments.1,2 It is a TGA listed medical device, available without a prescription.9
Overview
What is Steadi-3 Plus?
The Steadi-3 Plus is a lightweight assistive device worn on the back of the hand. It uses the same idea as the dampers that steady tall buildings: a mass inside moves opposite to your tremor and absorbs it. Attracting magnets let it retune itself as your hand moves, so there is nothing to charge, set or calibrate.4
Not all gloves for tremors use the same mechanism. The Steadi-3 Plus is a purpose-built essential tremor glove: instead of relying on weight alone, it uses passive magnetic stabilisation to counteract tremor motion, with no batteries and no charging. A healthcare provider can help determine whether it is appropriate.

How it works
Steadi-3 PlusTechnology Explained
The Steadi-3 Plus is a Class I medical device that supports people with Essential Tremor or Parkinson’s Disease tremors.Using advanced tremor glove technology, this hand stabiliser device improves control and independence, offering an effective Essential Tremor solution.
Borrowed from earthquake engineering
A tall building is steadied by a tuned mass damper: a heavy mass that moves out of step with the building and absorbs its sway. A building sways at one frequency, so one spring is enough. Tremor moves: it changes between people, and within one person with fatigue, medication and the task.
Lab test, November 2025: on an instrumented test rig, the device absorbed 2 to 3 times more vibration than the same weight added passively, and added no new frequencies.4 A test rig is not a hand, so this shows how the mechanism works, not how much a person’s tremor will drop.
Clinical Evidence
Neurologist-rated tremor reduction across everyday tasks
These figures come from small studies (9 and 12 people) designed and funded by Steadiwear.1,2 The first two describe how many participants improved, not how much tremor was removed. Results vary from person to person.
8 in 10
vs no device
Participants with a lower (better) tremor severity rating from a blinded neurologist when wearing the device than when wearing nothing. Blinded study, 9 adults with Essential Tremor.2,6
7 in 10
vs weighted placebo
Compared with a placebo device of identical look and weight, worn by the same participants. This controls for the effect of added weight and expectation.2
43%
lower severity vs no device
Average fall in clinician-rated tremor severity across three tasks. Against the weighted placebo, the average fall was 29%.2
83%
after one week at home
Participants in a separate one-week follow-up (12 people) who reported significant improvement, with no adverse events. Self-reported, with no comparison group.1
The same spiral, minutes apart
The Archimedes spiral is one of the three tasks scored blind in the study. These proof-of-concept tracings come from one person with moderate to severe Essential Tremor.
How the study was run
Nine adults with Essential Tremor did three tasks (drinking from a cup, finger to nose, and drawing an Archimedes spiral) under three conditions, in random order:
Nine adults with Essential Tremor did three tasks (drinking from a cup, finger to nose, and drawing an Archimedes spiral) under three conditions, in random order:
- No device.
- A weighted placebo device of identical appearance, with no active mechanism.
- The Steadi-3.Blinding
Recordings were masked, then scored blind by a neurologist on a modified Fahn-Tolosa-Marín scale. The scorer did not know which condition they were watching.
Funding
The study was designed, run and funded by Steadiwear Inc. (internal report, February 2025, available on request). Read the results with that in mind.2
Without the device
With the Steadi-3
Post-market survey, 62 users
What users report in daily life
Users rated how hard eight everyday tasks were before and while using the device. Whole-hand tasks responded most: writing, pouring, eating and drinking. Fine finger tasks like buttoning responded least.3
These are estimates converted from self-reported difficulty, not measured tremor, and the survey has no comparison group. In a survey of users, people who chose to keep the device reported an estimated average tremor reduction of 44%. People who returned it reported almost no change.3

Bench Testing
On an instrumented six-degree-of-freedom test rig (November 2025), the Steadi-3 Plus reduced transmitted movement by 52% or more across the tremor range, and by 2 to 3 times more than the same weight added passively. Frequency analysis confirmed it adds no new vibration frequencies.4 A test rig is not a hand, so these figures show how the mechanism works, not how much a person’s tremor will drop.
Independent study of the earlier Steadi-1
Independent investigators with no financial tie to Steadiwear tested the earlier Steadi-1 in 20 adults with Essential Tremor, against a weight-matched 550 g sham glove. Measured acceleration was lower with the device than with the sham in three of four tasks, and significantly lower on spiral drawing. The results were presented at the 2026 International Congress of Parkinson’s Disease and Movement Disorders; the full paper is pending.5
Safety
No adverse events were reported in the one-week follow-up.1 The device is validated for up to 16 hours of continuous daily wear.10 It has no battery, electronics or skin stimulation. It contains permanent magnets and carries labelling for magnetic fields and MRI, so people with an implanted medical device should talk to their healthcare provider first.10
Limitations of this evidence
- No randomised controlled trial yet. The controlled studies are small crossover evaluations (9 and 20 people).2,5
- No head-to-head comparison with any other tremor device.
- The evidence is mostly in Essential Tremor. Parkinson’s Disease is represented by 5 survey respondents and no controlled data.3
- Three of the four datasets were designed, run or funded by Steadiwear.1
- The survey is self-reported and unblinded, and its amplitude figures are estimates.3
- About 2 in 10 participants did not improve compared with no device, and 3 in 10 compared with the placebo.2
- Durability beyond one year of wear is not yet characterised.1,10
The Cala Trio, a prescription device in the USA, has been tested in published randomised trials.11 No study has yet compared it directly with the Steadi-3 Plus, so the two can’t be ranked against each other.10
Evidence in progress
- A real-world outcomes manuscript is under revision at Tremor and Other Hyperkinetic Movements.3
- The full paper from the independent Steadi-1 study is pending.5
- A multi-hospital clinical study is under way in Turkey, covering Essential Tremor and Parkinson’s Disease.1
- A three-year post-market durability survey is planned.1
Patient selection
Is Steadi-3 Plus right for your patient?
The response is strongest on whole-limb tasks and weakest on fine finger tasks.3 That gradient is the selection rule.
Most likely to benefit
- Difficulty with cups, cutlery, pouring or signing
- Action or postural tremor of Essential Tremor or Parkinson’s
- Partial response to medication, or intolerance of it
- Patients who can’t predict when they’ll need a steady hand
- Declined surgery, or not a surgical candidate
- Both hands involved
Less likely to benefit
- Primary complaint is buttons, zips, keys or small screens
- Wrist pathology or proximal weakness: 300 g may not suit
- Tremor outside roughly 4 to 8 Hz10
- Patient won’t accept a visible device on the wrist
- Expecting the tremor to be eliminated rather than reduced
Response can vary with medication timing, sleep, stress and exercise.
Assessing a patient in clinic
Pick the task, then baseline it
-
- Ask which everyday task the patient finds hardest. Pouring a glass of water and signing a name are the highest-yield. Have them do it without the device while you watch.
Fit the device and repeat
-
- Fit it correctly: a loose or badly positioned unit underperforms. Repeat the same task within a minute. The effect is immediate.
Read the result
-
- A positive assessment is visible steadying within seconds. Little or no change on repeat means that patient is better served elsewhere, and you know it in the room.

FAQs
Clinician FAQs
Is the Steadi-3 Plus clinically proven?
We don’t use that term: no single small study proves a device works for everyone. In a blinded, placebo-controlled study of 9 people, 8 in 10 improved compared with no device and 7 in 10 compared with a weighted placebo.1,2 Larger studies are under way.
Why isn't the study published yet?
The blinded evaluation is complete and documented in an internal report. A real-world outcomes manuscript is under revision at Tremor and Other Hyperkinetic Movements, and a multi-hospital study is running in Turkey.1,3
What is the sample size?
Nine people in the blinded, placebo-controlled study, 12 in the one-week follow-up and 62 in the post-market survey. An independent study of the earlier Steadi-1 included 20 people.1,2,3,5
Can it be used alongside medication?
Yes. Steadi-3 Plus is non-pharmacological and can be used alongside a patient’s existing treatment plan.
How do patients purchase Steadi-3 Plus?
Patients can buy directly through Aurora Direct, www.auroradirect.com.au. Clinicians and practices can contact Aurora BioScience for more information on info@aurorabioscience.com.au
Was the study funded by Steadiwear?
Yes. Three of the four datasets were designed, run or funded by Steadiwear.1 The fourth, a study of the earlier Steadi-1, was run by independent investigators.5
