Elbow room for improvement

Here is another systematic review of from the Norwegian, Brazilian, British and Greek stable.

A systematic review with procedural assessments and meta-analysis of Low Level Laser Therapy in lateral elbow tendinopathy (tennis elbow) 

As  usual it finds that less power density is more effective (less power density, but more time) for reducing inflammation and improving tissue repair. It is a recurring theme on this blog and I hope you are making a note of it.

A pain in the …. Annals

The Annals of Internal Medicine published a review of the evidence of medications for acute and chronic low back pain. These are the clinical practice guidelines for the American Pain Society and American College of Physicians (available here via Pubmed). Laser did not get a recommendation because “no suitable reviews of LLLT were identified”.  It’s worth reading a letter to the editor that strongly criticizes the overview methodology and makes a case for LLLT. click here for the letter to the editor

For decades the Cold Laser / LLLT pioneers have preached to each-other about their work and published in LLLT dedicated journals. It is nice to see more LLLT being reported in other medical journals and in the main stream press. In my bi-monthly Literature Review for PMLS 30 papers were published outside the Laser press

Today Reuters Health Interviewed Jan Bjordal about a paper he co-authored and published in the American Journal of Sports Medicine

Top prize for laser paper

Not much I can add to this other than it is his second award this year from an orthopaedic conference for best paper.

Dear all
Our neck pain review with laser therapy won the main award (!) of the joint national neck and back pain congress in Oslo (400 physicians, spinal surgeons, physios, manual terapists and chiropractors are attending there).

I went home to Bergen yesterday because I did not expect it. They have just annonouced it in Oslo. I tried to get a plane back to receive it but I could not find one.

A systematic review with procedural assessments and meta-analysis of low level laser therapy in lateral elbow tendinopathy (tennis elbow).

BACKGROUND: Recent reviews have indicated that low level level laser therapy (LLLT) is ineffective in lateral elbow tendinopathy (LET) without assessing validity of treatment procedures and doses or the influence of prior steroid injections. METHODS: Systematic review with meta-analysis, with primary outcome measures of pain relief and/or global improvement and subgroup analyses of methodological quality, wavelengths and treatment procedures. RESULTS: 18 randomised placebo-controlled trials (RCTs) were identified with 13 RCTs (730 patients) meeting the criteria for meta-analysis. 12 RCTs satisfied half or more of the methodological criteria. Publication bias was detected by Egger’s graphical test, which showed a negative direction of bias. Ten of the trials included patients with poor prognosis caused by failed steroid injections or other treatment failures, or long symptom duration … Continue reading

Phil Passy, Founder of MedX Health dies

I was shocked when I heard that Phil Passy died unexpectedly 22nd February 2008. Phil was Founder, President and CEO of MedX Health and a fellow industry pioneer. I first met Phil in the year 2000 in Athens, Greece at the World Association for Laser Therapy meeting when he boldly asserted that one day LLLT products would move from highly individual products competing on technical differences to a near commodity product as industry standards for the technology and treatments were agreed. It was a visionary statement that I thought was crazy but now I believe he will ultimately be proven right. Any new technology requires passionate and persistent personalities behind it striving for years to achieve widespread adoption and Phil was one of bravest and hardest working figures in the industry. He radiated passion and his dogged persistence has created a publicly listed company leaving an indelible mark on the history of LLLT. Medicine is an exceptionally tough field to create a radical breakthrough in and whilst many have resorted to snake oil sales methods, … Continue reading

Realtime video of cellular response to pulsed near infrared “Light”

Cell signalling governs basic cellular activities and coordinates cell actions. Cells respond to their local microenvironment and these signals may prompt tissue repair or immune response as well as normal tissue homeostasis. Guenter Albrecht-Buehler has conducted a series of experiments on cells with near-infrared light (NIR) and reports on how cells might be communicating with pulsed NIR. He also demonstrates with video how cell motility responds to a pulsed light stimulus.
