Motorised stabilising handle with spoon and cup heads made for Indian meals
TL;DR Tremorspoon is a battery-powered handle that senses hand tremor and moves its tip the opposite way, so the food stays on the spoon. It comes with a deep bowl for dal and rice and a cup holder. People with essential tremor or Parkinson's, or their families, buy it through neurologists and patient groups.
India has about 5.76 lakh people with Parkinson's disease[1]. Essential tremor is probably more common - a rural Gujarat survey of nearly 19,000 people found it in about 90 per lakh[2]. Put together, that suggests a tremor population in the high lakhs (my estimate).
The daily cost shows up at meals. In a South Indian hospital study of 45 people with essential tremor, holding a glass was the hardest task, with 25 unable to drink comfortably with one hand and eight relying on a straw[3].
Their average age was 44, so this hits people who are still at work, not only the elderly. Many simply give up eating in front of others.
First, the regulatory bit - this is an assistive eating aid that steadies a utensil. It does not treat, reduce or monitor the disease itself. It's likely a low-risk Class A or B device under the Medical Devices Rules 2017, but get CDSCO to confirm the class before you sell.
A motion sensor in the handle reads the hand's shaking many times a second and two small motors move the attachment in the opposite direction. Heads click on and off - a deep spoon for dal, rice and curd, a fork, and a cup clip that keeps a glass upright. It's washable and charges on a standard phone charger.
We reframed one part of the seed, the word "cancellation". The best-known active spoon cut shaking at the utensil by 71–76% in a 15-person pilot. That study didn't show better eating though, and two people with severe tremor didn't benefit[4]. So Tremorspoon promises steadier spoons and cups for mild to moderate tremor, not still hands.
The user is usually 45 or older and the buyer is often an adult child. Imported options cost far more than most Indian homes will spend. The best-known stabilising spoon launched at US$195 (about ₹18,900)[5], a passive damping glove sells for US$999 (about ₹96,600)[6], and a gyroscope glove costs US$5,899 (about ₹5.7 L)[7].
A locally made handle at ₹6,000–9,000 (my estimate) would cost a fraction of these. Physiotherapy centres may also buy demo units.
Its maker shut that devices programme in August 2025, and by August 2026 the spoon was sold out[4]. That leaves a gap at the price point where it sat. A Bengaluru teenager's low-cost prototype spoon went into testing with physiotherapists in 2023[8], which shows there's local demand and local design feedback to tap. India's Class A licensing exemption for non-sterile, non-measuring devices took effect in October 2022.
We found no market figure for tremor aids in India. The firm number is the patient base, about 5.76 lakh people with Parkinson's[1] plus essential tremor at around 90 per lakh[2].
The Parkinson's Disease and Movement Disorder Society runs 60+ centres in 15 states and has reached 40,000+ people[9]. That gives you a feel for how many patients one channel can reach.
The US stabilising spoon defined the category and is now hard to buy[4]. A Chinese maker sells a similar spoon. A Canadian firm makes a passive glove with no battery[6]. A US company sells a prescription wrist stimulator for essential tremor, backed by a 310-patient trial[10], but it doesn't ship to India. A Bengaluru student's prototype is the only Indian effort we found[8].
The gap is a serviced, locally priced aid designed for Indian food.
| Difficulty | Moderate (42/100) |
| Starting capital | ₹60 L–1.1 Cr |
| Time to launch | 9–14 months |
The control electronics are well understood. The hard parts are making the motors survive daily washing and spice-laden food, getting the cost low enough and reaching patients who are scattered across the country. Each buyer is one family, so you need trusted channels such as neurologists and support groups rather than paid ads.
Yes, though probably a light one. It's a low-risk device, but you need its class confirmed before you sell.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't let AI write medical claims. Tremorspoon steadies a utensil and doesn't treat tremor, so every chatbot reply and ad has to say the same.

Here's what can go south -
I have a soft spot for small, useful products like this one. If you're a hardware founder who can build relationships with neurologists then it's a good fit. If your investors want a fast-scaling platform then it is the wrong pitch.
First prove that 30 Indian users keep using the handle daily after four weeks, including for Indian meals, and that families will pay ₹6,000 or more.
My estimate is ₹60 L–1.1 Cr, covering design, tooling, testing and the first production run. The kit breaks it down.
Probably a light one. It's likely a low-risk Class A or B device, so get CDSCO to confirm the class before you sell.
Yes, shaking hands aren't an Indian problem. Device rules differ by country though, so check with your local regulator before you ship.

Thinking about building Tremorspoon or something close to it? The make-or-break work is a design that survives Indian kitchens at a price families will actually pay, and that's the kind of problem I like working through with founders. If you need a hand, you know where to find me. Talk to Yash →
