My latest forearm extensor RSI rehab effort

As you will know from reading this blog, I have had a chronic RSI condition in my forearms for over 14 years. I live with it by avoiding computer use as much as possible. Whilst resigned to having this condition long term,  I am always looking at ways to try to rehabilitate it somehow. Usually when things get more painful I resort to digging out an old, vigorous Homedics massager that I bought in the US. It’s a heavy duty one that is probably more designed for deep tissue massage of the back and neck, however, it can and is used by me to reach deep into the forearm extensor muscles for a relieving massage (although you have to be careful not to overdo it). This usually takes the pain down to background levels, at least temporarily.

The massager is, however, still only treating the symptoms of the RSI. What I really need is to try to strengthen the forearm muscles to an extent where they can resume being normal muscles tissue again (as opposed to the knotted, tense mass that is there right now). I have always drawn a blank as to how to do this.

NSD Power Ball gyroscope

I recently came across a friend with a NSD PowerBall Gyroscope (which I’d seen plenty of advertisements for but hadn’t got round to trying out), and my curiosity got the better of me. Amongst its claims is that it can be used as a “Rehabilitation product bringing gentle non-impact relief  to Carpal Tunnel syndrome (CTS), Repetitive strain injury (RSI), tendinitis, arthritis, and all wrist related ailments. Spinning for just five to seven minutes per day is enough to start your rehab!”.  Lofty claims indeed! I was keen to get my own Power Ball and get started!

The units are actually quite inexpensive (less than £10 for the basic model). The more expensive ones have electronic counters in them so you can count rotations and gyroscope speed RPM, which I decided was superfluous to my requirements. My NSD Power Ball arrived in a few days from Amazon and I ripped the package open with great enthusiasm and interest, as well as much hope!

The theory behind the Power Ball is that spinning the gyroscope inside the ball offers a resistance to motion of the ball. Spinning  the gyroscope is started by means of a short piece of string (or alternatively by means of an additional electric base unit at extra cost). Rotation of the ball with the hand/wrist keeps the gyroscope running and maintains resistance. The gyroscope, when in motion, will actually start to produce a gentle whirring sound. The faster the hand/wrist rotation, the faster the gyroscope spins and the more resistance the ball offers and vice versa. The resistance that you encounter is therefore  controllable in infinite degrees, and can be tailored to your own needs (or degrees of injury) which is useful.


What I have found thus far (after about 1 week’s use) is that it is a really good way of getting the forearm extensors exercised in an aerobic manner (as opposed to the continuous micro movements that computer keyboard/mouse input dictates, which can lead to RSI conditions). I can honestly say that I have never felt the forearm muscles heat up as much, which is surely a good thing (I can sense blood rushing into them, which will hopefully be good to promote healing).  I am also coupling this with using a medium/low strength Gripmaster hand exerciser, and adding in a few forearm stretches too. I am keeping this routine to 2 to 3 x 10 to 15 minute timeslots each day. I realise that it’s important not to overdo it!

Having had such a long term injury, I am under no illusions as to the uphill battle I face to rehabilitate it, and it’s still too early to assess the long term benefits of using the Power Ball Gyroscope with a forearm extensor RSI injury such as mine, but so far I haven’t needed to use the big massager for forearm extensor pain relief again which is a good sign! I will report back here after more prolonged use to let you know how things are working out. I at least have a little hope to cling on to for now!

RSI Tips

Medical Solutions – Physical Therapy

Often RSI sufferers will be referred by their doctor for physical therapy, which in my experience can range from ‘wonderful’ to ‘complete waste of time’ depending on the experience and attention of the physiotherapist. The most wonderful physical therapy treatment I received for RSI was when living (and working) in Silicon Valley in California. I believe physiotherapists out there were more used to seeing cases of computer related injuries what with the region being the heart of the high tech industry. What did they do that helped with the pain relief so much? Treatments included –
