For patients and families
If your hands shake, or someone you love has a brain that is not carrying signals the way it used to, this page is for you.
We want to tell you plainly what we are building, what it is not yet, and how you can follow along. We will not oversell it. You have probably had enough of that.
What we are building
A sleeve that works on the signal, not the symptom.
This is SureHand. A soft sleeve, a sensor at the elbow, a sensor at the wrist, and thread woven through the fabric between them. It is a design drawing of what we are building, not a photograph of a finished device.
It is meant to go on in the morning, with one hand, and be forgotten until evening.
Tremor starts as a signal. Your brain sends an instruction to your hand, and somewhere along the way a second, unwanted rhythm rides along with it. The hand receives both. It does what it is told, and what it is told is shake.
SureHand is a soft sleeve worn on the forearm. A sensor at the elbow reads that signal before it reaches the hand. Software inside the sleeve tells the instruction apart from the tremor, and then thin wire woven into the fabric sends a small signal of its own, timed to push against the shake. The instruction gets through. The tremor is opposed. A second sensor at the wrist watches what your hand actually did and tells the software how to do better next time.
You put it on in the morning. It runs all day. No pills, no surgery, no wires to a box.
The sensors and the software are one product, which we call the HemiSense Array. The sleeve is an add-on that plugs into it. We are building the two arm sensors and the sleeve first. Later, the same sensors and software will be worn elsewhere on the body, and other add-ons will plug in.
Beyond tremor
The same idea reaches further than the hand.
The sensors that read a tremor signal at the elbow can be placed elsewhere on the body to read other things. We are starting with four conditions. Each one is a place where the nervous system stops carrying signals faithfully, and each one leaves a signature a sensor can read.
Parkinson's disease
Tremor, stiffness and slow movement, and the way symptoms come and go as medication wears on and off through the day. SureHand starts here.
Epilepsy
Knowing a seizure is happening, and the harder thing, knowing one is coming. We are exploring whether the array can see the warning signs early enough to matter.
Alzheimer's and memory loss
Catching the earliest changes and following them over months, in a person's own home rather than a clinic visit twice a year.
Stroke recovery
Measuring recovery honestly between therapy sessions, so a person and their family can see progress instead of guessing at it.
Honest answers
Questions we are asked most.
- Can I get one?
- Not yet. SureHand is not for sale and has not been tested in patients. We are working toward a first study with clinical partners. We will not sell a device before it has been through that.
- Does it give medication?
- No. The sleeve does not contain or dispense any drug. It works entirely on the electrical signal between the nervous system and the hand.
- Does it replace my doctor?
- No. It records what it measures and what it did, in plain terms, so that your doctor has better information than a memory of how your week went. Decisions about your care stay with you and your care team.
- Is it safe?
- We cannot say that yet, and anyone who tells you a device like this is safe before it has been studied is guessing. Answering that question properly is what a feasibility study is for.
- Can I be part of a study?
- When a study is planned, it will be run through a clinical partner with proper ethical oversight, and enrollment will go through them. If you would like to hear when that happens, write to us and say so. We will keep your name and nothing else.
Why we are doing this
Because a twenty minute visit twice a year is not a picture of a life.
Neurological conditions are now the leading cause of illness and disability in the world. More than one in three people live with one, according to the World Health Organization. And most of them are still cared for on snapshots. A short appointment. A description from memory. A number written on a form.
The disease is continuous. The care is not. We think a wearable that reads the signal, acts on it, and explains itself can close some of that gap. Not all of it. Some of it, honestly measured, for the people who need it most.
A promise about language. We will not use the word cure. We will not tell you what the sleeve does for people until we have measured what it does for people. Everything on this site is in development, and we say so on every page. That is not a disclaimer. It is respect.
Follow along.
