IDD therapy for lumbar disc problems in Edinburgh
To my knowledge there is only one clinic providing IDD therapy for lumbar disc problems in Edinburgh. And yet IDD has been around for the best part of 20 years (20 in the USA, but over 10 years in the UK). Why is this? Does IDD actually work?
Why isn’t IDD therapy practised more widely?
1. It’s expensive. The most obvious people to offer IDD therapy are manual therapists – osteopaths, chiropractors and physios. But their clients aren’t used to paying the kind of fees we’re talking here. It’s a big commitment financially, and health insurers in the UK don’t cover it. There’s no point in having 1 or 2 sessions. I think the minimum is 6, but more commonly 10-20 sessions, which would easily amount to £600+. That’s still a lot less then surgery however.
2. It’s a large piece of equipment. I don’t have room for one in my practice – I’m sure many other practitioners are the same.
Does IDD for back pain / sciatica actually work?
As ever, the answer to this isn’t straight forward. I’m sure there are people who have benefited from IDD therapy. But what does the science say? On the IDD therapy evidence page for the main UK distributor, they showcase the scientific literature published in support of the device. They state “The manufacturers of SPINA machines and IDD Therapy put forward the treatment for independent testing and are transparent in the presentation and publication of data. ” As part of this transparency they cite a number of articles. I was looking for reviews, where researchers will collate data from a number of studies and report on the generalised findings across those studies. However, none of the articles were reviews (I don’t think there’s enough research to warrant someone to undertake a review), and certainly none were “systematic reviews of placebo controlled trials” (the best kind of review). The best article I could find (in terms of quality of research) in so far as it mentioned “single blind, randomized controlled trial” in the title is linked to here*. It’s not very promising however, with there being no significant difference between IDD therapy and sham IDD therapy. However, both of the groups – in conjunction with a “standard graded activity program” – improved significantly during the study period.
Would I try IDD therapy?
Yes. If I had intractable sciatic pain and I felt that it might be a useful addition to all the other strategies I can employ to speed up healing and avoid aggravating my sciatica I would certainly consider it. I have recommended other patients try it in order to avoid surgery. However, neither of the two I recommended it to felt any benefit and one certainly felt considerable discomfort. So, I’m afraid – while I’m open to it benefiting some people some of the time – like most clinical interventions (including osteopathy) it won’t help all of the people all of the time. 🙁
