RSI Pain Relief Device

This device may be the solution for a lot of RSI sufferers when using a computer.. including gamers.

This device is still 'on paper' i.e. at concept stage but is based on a similar system devised by the inventor. This original system was used to prove the concept. UK patent granted.


Brief  Description

This is a mechanical device to relieve the pain of repetitive strain injury in the muscles, joints and tendons, of the human arm, shoulder and back, principally when using a computer. It may also assist people with Brachial Plexus Injuries.

The inventor of the device outlined here suffered tremendous pain in his arm and wrist whilst using a computer in his daily work, and was concerned he would not be able to continue. This was very serious because the use of a computer was essential to his occupation. He invented the following device to reduce the pain.  

Repetitive Strain Injury can occur as an acute pain in the muscles of the wrist, arm, shoulder and back, caused by using the arm for a repetitive activity under conditions with which the arm is not familiar. An example of this is using a computer mouse or keyboard for long periods.

The device is based a rough prototype which proved the efficacy but was not suitable for consumer use. The design will need prototyping and clinical testing.

The concept has been checked by the relevant medical professionals. This was done by a local company, based in Bath, called Designability (Bath Institute of Medical Engineering) http://www.designability.org.uk/  . See a brief extract from an email from them below ….. 

Dear David.
I have now had a chance to review this with Nina Evans, Research Occupational 
Therapist and Tony Husband, Commercial Director at Designability. The principle behind the idea is credible and we understand the potential benefits. Well done. Keir Haines. Senior Product Designer.

Therapist feedback summary:

- It is agreed that the principle of ...........(details exclude here to avoid concept theft) ..... can reduce strain on the injury and provide comfort and potentially reduce pain.
- The concept of a streamlined, lightweight and flexible design solution .........(details exclude here to avoid concept theft) ........ is a nice idea.

A company was contacted which supplies medical devices of this type and the response was:

Thank you for the information about your new product. 
I think the idea is brilliant and I am sure the potential for sales would be extremely high. However as I have explained to you on the telephone as a small family business we do not feel we are in a position to fully maximize the potential of this excellent idea. My experience of being in the profession for over thirty years leads me to believe that this has a very high chance of being a viable and very profitable product. I would be inclined to seek a large manufacturer of soft good medical products to help you with this project. 
May I wish you every success in the future. 
Best regards 
John Mines, Managing Director, JPM Products Limited,



Current alternatives     

There are some devices available such as wrist splints, or wrist supports, which have very little effect. Other suggestions include exercises, and painkillers, neither of which gets to the root of the problem.  

Repetitive strain injury, in the case of computer use, is caused by a reaction in the arm muscles whilst they are supporting and suspending the human arm, with the hand on the keyboard, for long periods of time. Holding the arm in this horizontal position for long periods, and only moving it slightly up or down or side to side is completely alien to the muscles of the arm. So eventually the muscles that support the arm react to this, and start to cause significant pain.


The Market       


If you research the RSI problem on the Internet, or anywhere else, you will find the sort of information shown below. Bearing in mind this is probably anecdotal to a certain degree, and unreliable, and the device described here will only work with certain types of RSI, there should still be sufficient market for this device to make it financially worthwhile. 

Source - Wikipedia - 'A 2008 study showed that 68% of UK workers suffered from some sort of RSI, with the most common problem areas being the back, shoulders, wrists, and hands.' 

Source - www.rsi.org.uk  - RSIO awareness website -  'In 2006 nearly half a million people in the UK suffered from some form of RSI. The problem is increasing principally through the intensive use of computers and other technology that involves large amounts of keyboarding. Posture related health problems are also growing due to the sedentary nature of many jobs.' 

Source - The Sun - 'It is among the most prevalent forms of RSI, which causes 5.4million sick days every year'… 

Source - www.tuc.org.uk  - http://www.tuc.org.uk/workplace/index.cfm?mins=155&minors=124&majorsubjectID=2  'Repetitive strain injuries affect hundreds of thousands of workers every year in Britain…..'   



The Story So far - This is a potted history of the invention, and the progress made by the inventor to raise money and develop this device for the retail market.


The inventor suffered severe pain in his arm and back whilst using a computer. His work involved using a computer for long periods most days, and this pain prevented him from doing so. This was potentially a very serious problem because he was self-employed and could not take time off work as a salaried employee might be able to do. i.e. if he stopped working his income would immediately stop.

Researching the problem on the Internet, he found that there was no real cure for this problem apart from pain killers which just 'hide' the problem in the short term, exercises which don't always work and require perseverance on the part of the patient which is often lacking, and a few devices like wrist supports which had little effect. However there were many many articles written by 'sufferers' who had lost their jobs, or incurred terrible pain and discomfort. (See 'The Market' above)

Knowing a small amount about the human anatomy, the inventor decided to make a device which might eliminate the pain. After a lot of trial and error, and adjustments to the device, he found that the pain went away completely. Visitors to his office found it amusing to see him using this device but it definitely worked. If he stopped using it the pain came back, and if started using it again, the pain went away - as simple as that.

The inventor feels that this prototype clearly identified the problem and the solution.

However the device was far too 'Heath Robinson' to be viable as a marketable device. So the inventor re-designed it in a way which would be acceptable to the general public.

This design has been discussed with an engineering CAD designer at length, and the designer did not see any problems with the design, or potential manufacturing process. The inventor has not made a 'proper' prototype because his engineering skills are not sufficient to make a convincing device, he decided to wait until he could raise the money to have it made professionally.

These drawings were sufficient for the device to be granted a UK Patent.

This device has been shown to some companies in the UK which make orthopedic devices, but it was outside their normal product range. Most devices of this type are made in the USA or the Far East There is virtually no manufacturing of this type of product in the UK - a  sad reflection on our great engineering history. The inventor of the device wants to keep the manufacturing in the UK.

Orthopedic engineers at these companies could find no problem with the device, and one suggested that it would also help people with upper arm injuries - Brachial Plexus Injuries - which have severely reduced their arm usage. The device would take the weight off the arm enabling the remaining limited muscle power to move the arm around.


What will the money be spent on?


Additional Market Research

CAD technical drawings and design revisions / improvements.


Clinical testing on actual patients.

Note: The money required is to get the project to 'working prototype' stage. When it has reached this stage, further funds will be required to get the device into production, plus marketing, admin etc etc. These costs are difficult to work out at the moment, but when a working prototype has been produced it will be easier to estimate these costs.


If we raise the finance, what do the investors get for their money?


The investors will get a shareholding in the business or one of the devices at a significant discount on retail price, or both.

1) A shareholding - Pure investors, as opposed to RSI sufferers will normally receive a shareholding rather than receiving one of the devices at a discounted price. However they might want both - it's impossible to be too specific at this stage.

2) Discounted retail price - It's difficult to be specific at this stage because the manufacturing costs are not yet known, neither is the retail cost.

The main advantage here, is that the person would get a device which solves their pain and discomfort, which would not have been available otherwise, if they hadn't made the investment. So it's not the cost which is really the issue, but enabling people to go about their normal work activities.
