International Research Studies Involving the TMJ Scale-Canada

In addition to the many published research studies over the years in the U.S. involving the TMJ Scale, studies in other countries and cultures have also been ongoing.  Many have expressed an interest in reading about such studies.  Therefore, this is one example of a study done in Ottawa, Canada.

Wexler GB, McKinney MW. Assessing Treatment Outcomes in Two TMD Diagnostic Categories Employing a Validated Psychometric Test. Jour of Craniomandib Practice, 13(4):256-263, 1995.

Publication Abstract:

This study measures the effects of treatment interventions on two classes of temporomandibular disorder (TMD) patients in a dental practice in Ottawa, Canada. Other studies of TMD treatment outcome have employed subjective, largely qualitative and nonquantitative measures of symptom levels to make this type of assessment, rendering such research largely incapable of being replicated. The current study employs the TMJ Scale, a validated and psychometrically-developed symptom inventory, to measure symptom levels before and after treatment. The study first determined the sensitivity (92.1%) and specificity (88.1%) of the TMJ Scale for 219 patients in the practice population. One hundred and eleven consecutive TMD patients completed TMJ Scales prior to treatment, and then were retested after the completion of treatment. Results indicate that patients with symptoms of internal joint derangement reported more symptomatic improvement than those with predominantly muscular symptomology, despite the fact that the latter manifested lower symptom levels initially. Patients with internal derangement symptoms initially presented with lower levels of psychological symptoms than patients with muscular symptoms. Substantial improvements in both groups were noted, employing TMJ Scale percentile rank changes as outcome measures. This study can serve as a model for future research toward establishing baselines for expected TMD symptom improvement.

    I suffered from severe knee joints pain before I discovered the Painfreeology
    products. I had suffered from painful joints for almost 5 years. I was told to have
    severe osteoarthritis and 2 different doctors had recommended knee joint surgery. I
    tried all the pain medications that are available in the market but nothing
    helped.  After taking Dolrx and Orthopen and applying senscool gel for 3 weeks I
    felt 90% better. Initially I was not taking the suggested dose of Dolrx and Orthopen
    that is why I think it took me 3 weeks. Nevertheless, after taking it for almost 6
    weeks I feel much better and living a pain free life. The good thing about
    painfreeology is that all the ingredients of their products are natural and that is
    why I have no side effects. Even the capsule is vegetable form. I will highly
    recommend this product to all of you out there who are suffering from pain,
