Regardless of all the written testimonials on the website? What do you put that down to?
What do I put it down to?
I put it down to the following:
1) Anybody, including Wilden's brother-in-law, can write a testimonial. The presence of a testimonial on a website is no assurance whatsoever of its validity.
2) For all you or I know, there are 10,000 testimonials of utter failure. In fact, Wilden's failure rate might be worse than placebo failure rate ... and the LLLT might actually inhibit natural resolution of tinnitus. Who's to say?
3) There is not a single credible reliable and independently verifiable double-blind randomized prospective study in the juried scientific literature attesting to the efficacy of LLLT in tinnitus. The reliable and verifiable studies all point to lack of efficacy.
4) Tinnitus affects 20% of the industrialized world. Like I already said, if Wilden's claims are true, he'd have been awarded a Nobel prize.
From another poster on another tinnitus board:
The purpose of this thread is to provide information – and a reality check – about the use of Low Level Laser Therapy to manage tinnitus. The newly released Textbook of Tinnitus contains a chapter about this approach, and I offered to summarize the chapter, which was written by one of the book's editors, Dr. Tobias Kleinjung, from the Department of Otorhinolaryngology, University Hospital of Regensburg, Germany. Dr. Kleinjung is well-positioned to offer his views on laser therapy because he is familiar with the clinical use of laser technology in his field as well as the associated literature. As he explains, "hard" surgical lasers have been used successfully by neurotologists to remove tumors of the larynx and pharynx, and to perform stapes surgery.
Another type of laser, known as a "soft" or diode laser, has about one hundredth of the power of a surgical laser; therefore when a "soft" laser is used, it is known as low level laser therapy (LLLT). Soft lasers have been used to speed up the healing of injured peripheral nerves, cutaneous wounds, and burns. They have also been used for soft-tissue injuries, to reduce inflammation, and to provide relief from chronic pain. The clinical effectiveness of LLLT is controversial for each of these applications. That is, when used to treat tennis elbow, chronic pain associated with rheumatoid arthritis, and venous ulceration, some studies indicated LLLT was effective while other studies failed to show LLLT was effective in managing chronic pain. Another study concluded LLLT had a positive impact on the nervous system by preventing neuronal degeneration, improving neuronal function and repair, and enhancing neural growth.
Based on the positive studies, LLLT was proposed by Wilden to treat chronic disease of the inner ear (1996), by Mirz to treat tinnitus (1999), and by Tauber to treat cochlear dysfunction including chronic tinnitus and sensorineural hearing loss (2003).
Treatment in LLLT is performed with red to near infrared light. When used to treat tinnitus, the light is applied through the ear canal; however, we do not know if the laser light can penetrate the soft tissue, or reach the cochlea and cochlear hair cells. In addition, the strength of the laser light may be scattered and diffused by coming into contact with red blood cells and micro vessels. A study by Tauber (2001) using human temporal bones (specifically, the petrous – the hard portion of the temporal bone that forms a protective case for the inner ear) concluded only the transmeatal application of LLLT enables enough laser light to reach the entire cochlea whereas the application of laser light via the mastoid portion of the temporal bone did not enable enough light to reach the cochlea.
LLLT has been around for almost 20 years, and numerous placebo-controlled clinical studies have concluded LLLT provides absolutely no benefit when used to treat tinnitus and some inner ear conditions. Studies by Partheniadis-Stumpf (1993), Wedel (in a placebo-controlled study from 1995), Mirz (1999), Nakashima (2002), and Teggi (2009) concluded LLLT failed to treat tinnitus. Only a few reports have concluded LLLT can be an effective approach (e.g., Wilden's 1996 study without placebo control, Shiomi's preliminary report from 1997, Tauber's 2003 feasibility study, and Gungor in 2008).
Wilden is the only clinician to claim LLLT can improve hearing thresholds – in 1999, he claimed in a trade journal that 80% of subjects said their hearing improved. However, there were no improvements in hearing in studies by Partheniadis-Stumpf (1993), Plath (1995), Mirz (1999), Tauber (2003), and Teggi (2009), and Nakashima reported in 2002 that one patient experienced acute hearing loss after the third laser treatment.
In an important review of randomized controlled clinical trials of LLLT and other alternative therapies to treat tinnitus by Meehan in 2004, no difference was found between laser and placebo.
Dr. Kleinjung concludes because "multiple placebo-controlled clinical studies failed to demonstrate significant efficacy, further studies are needed before this treatment modality can be recommended for routine clinical use."
