TMJ pain can be a real problem for its victims, limiting their ability to chew and talk, and interrupting sleep. Often, headaches even limit the person’s ability to concentrate! Various treatments have been proposed to alleviate the symptoms of TMJ (Temporomandibular Joint) pain, many of which are very complex and even invasive. Looking at the TMJ as “just another joint” and not predetermining that it has to be complicated has been very freeing for me in using a mechanical approach. Let me explain using a patient example from this week in clinic.

My approach is modeled after the McKenzie Method of Mechanical Diagnosis and Therapy, although very little about TMJ specifically has been written or published about it. (1)

Symptoms and Experience

Now, about the patient. (Name and other identifying information has been omitted to protect privacy). This patient complained of intermittent left jaw pain with wide opening of the mouth. He stated it only occurred then, and otherwise it really was not painful. However, chewing tough foods, he admitted, was sometimes painful. His worst pain occurred with rapid opening of the mouth and could be as intense as 6 on a scale of 1-10.

Therapist’s Evaluation and Findings

Objective findings were limited and painful opening with slight left deviation, limited and painful protrusion, limited and painful right deviation, and no pain or limitation with retraction, or left deviation. Repeated tests performed actively by the patient of protrusion first, then of right deviation resulted in producing the patient’s symptoms, no worse after, but also no change in baseline ROM or pain. Forces were progressed to patient applied over-pressure to right deviation. The patient reported that this produced his pain initially, then decreased pain as he performed more repetitions. Subsequently, he reported wider opening with less pain!

Patient Homework

Home exercises were assigned, which naturally consisted of patient applied over-pressure into repeated right deviation every hour or two as per typical McKenzie protocol. On the second clinic visit two days later, the patient stated he was already 50% improved! This finding confirmed the mechanical diagnosis of derangement syndrome. In this classification, there is a good prognosis for rapid and lasting recovery from the problem.

Get Yourself Evaluated

This is only one clinical example of a purely mechanical TMJ problem. While there are examples of TMJ issues that are not derangements, or even mechanical, often a mechanical cause of the pain can be found and the patient helped by mechanical therapy. It is well worth a thorough examination to determine if your TMJ pain has a mechanical component, and to get appropriate treatment which would otherwise be missed.
