The author of Isokinetics.net:
Paul Spencer-Wimpenny MSc BHSc MCSP HCPC based in the UK first introduced an isokinetics resource to the world wide web in the year 2000 (on the 5th of May).
Paul is a chartered physiotherapist with a masters degree in sports science. He works with isokinetics and REAL patients on a daily basis. He lectures both post graduate and undergraduate and has taken part in many and varied pieces of isokinetics research. In his own words he has learnt through experience what works and what doesn't. Paul has experience with many different machines and has been an integral part of the development team for one manufacturer. He continues to work with several manufacturers to help develop their products.
Paul set up isokinetics.net as a reaction to a course run in the UK for Biodex and Kin-Com users (where the handout would have been hundreds of pages long). To make the resource easier to access, store and to decrease the use of paper the web site was created.
Isokinetics and isokinetic testing were first introduced to me at university. The Cybex, isokinetic only, system was state of the art then as far as isokinetics went. But by today's isokinetic or active dynamometer standards it was rudimentary to say the least. If you could run a concentric test at 90 degrees per second on the knee and get some results you were doing well. At higher speeds the machine became less reliable, as all machines from that era did, and frequently stopped working if the speed became too high.
After university gym orientated isokinetic type units (in my opinion not really isokinetic) were all I really had access to, although, I did for some time use a Biodex system II in an orthopaedic outpatient department (when time allowed).
Then I went to work in a sports injuries clinic. Isokinetic assessments and treatments were a daily activity here using a Kin-Com AP active dynamometer. This was not a user friendly machine and again it was unreliable at higher speeds, but it could be used up to 300 degrees per second (as long as your subject wasn't too strong) and it offered good feedback (if you were willing to put in the time and effort to set it up).
I began using isokinetic tests on any patient who wanted to return to sport (as I found the Oxford strength testing system totally inadequate for muscle performance).
Following a call from local practitioners (who had isokinetics machines but did not utilize them much) I started teaching/lecturing on isokinetics and active dynamometry.
I then completed a masters degree at Leeds University where I used my isokinetics experience to run several studies on human performance using the Cybex Norm. This was really the first active dynamometer that could cope with higher speeds. This in turn made allot of the research from the 1980's defunct as the Norm was reliable up to 400-500 degrees per second. The machine at the university had the smaller dynamometer which was later replaced by the newer higher specification dynamometer, a fantastic unit with more than enough power!
Continuing to teach clinically on the isokinetic systems I have subsequently facilitated/developed isokinetic services in many varied sports science services.
I was then asked to help to develop a new isokinetic machine (Isocom from Eurokinetics). This machine and it's producers had a 'no expense spared' approach which made the Isocom a high end machine. With a fantastic motor and gear box able to cope with high torque beyond 500 degrees per second the Isocom is still an elite level machine. the software was and still is the easiest to use I have ever seen costs saw the end of production.
Following development of the Isocom I continued teaching and moved with the times into isokinetic screening pre and post employment. This work has expanded and continues to do so for me world wide.
Currently I use a Humac Norm (complete with a closed chain unit). This is the latest of the Norm range with a fantastic range of features and great on-going development. It offers a mind boggling array of modes now which include the most comprehensive proprioceptive modes ever.
I continue to teach isokinetics (mainly post graduate now) and continue to assess and treat patients on a daily basis. I still do isokinetics research but limit this to larger pieces of work now.You will still find me answering questions through this site so if you have anything to ask please feel free through the ask a question link.
