Three-Part Question:
In [young adults with TMJ pain] do [physiotherapy techniques other than electrotherapy] improve [pain and function]
Clinical Scenario:
A 23 year old female has been referred to physiotherapy with a 6 month history of temporomandibular joint (TMJ) pain without disk displacement. Based on some published evidence, the referrers commonly request electrotherapy, but you want to investigate if other forms of physiotherapy may be more beneficial.
Search Strategy:
MEDLINE 1966-01/05, CINAHL 1982 –01/05, AMED 1985-01/05, SPORTDiscus 1830-01/05, EMBASE 1996-01/05, via the OVID interface and the Cochrane database In addition the PEDro database was also searched.
Search Details:
Medline, CINAHL, AMED, SPORTDiscus, EMBASE, Cochrane database for systematic reviews: (exp temporomandibular joint disorder OR temporomandibular joint dysfunction OR temporomandibular pain OR TMJ) AND (acupuncture OR massage OR relaxation techniques) AND (Physiotherapy.mp OR exp physical therapy techniques OR manual therapy) AND Electrotherapy AND (Physiotherapy OR physical therapy OR manual therapy). LIMITS human AND English Language.
PEDro: (temporomandibular joint)
PEDro: (temporomandibular joint)
Outcome:
14 papers were retrieved. One was a Cochrane review of stabilisation splintage. 1 was a systematic review of a number of physiotherapy techniques and 1 was a systematic review of acupuncture. One was a meta-analysis of biofeedback treatment. All the other papers were included in one or more of the reviews.

| Study Title | Patient Group | Study type (level of evidence) | Outcomes | Key results | Study Weaknesses |
|---|---|---|---|---|---|
| Stabilisation splint therapy for temporomandibular pain dysfunction syndrome Al-Ani MZ, Davies SJ, Gray RJM, Sloan P, Glenny AM. 2004 UK | 12 RCTs on splint stabilisation for the TMJN = 496 | Cochrane review. Level 1 | TMJ pain | NSS comparing TMJ splintage to other treatments. Weak evidence that splintage is better than 'no treatment'. | Variety of pain outcomes between RCTs.All RCTs failed to report randomisation and allocation concealment techniques.Blinded outcome in 2 RCTs only. Small sample sizes in all RCTs.Also possible that TMJ with and without disk displacement were combined |

| Acupuncture as a treatment for Temporomandibular Joint dysfunction. A systematic review of randomized trials. Ernst E. White AR. 1999 UK | 6 reports of 3 Trials N = 205 |
Systematic review | Subjective: e.g. VAS, Anamnestic index, Pain frequency, Use of medication. | Within group efficacy but NSS between groups. In 1 trial 53% improved with acupuncture & 63% improved with occlusal splints.Acupuncture significantly (P<.01) superior to no treatment or waiting list controls and sustained for 1 year.1 trial acupuncture better (p<.001) occlusal splints & no treatment | No placebo control in any trial. Randomisation & Blinding not described. 3 trials suggest efficacy of acupuncture |
| TMJ dysfunction e.g.Dysfunction index. Mouth opening. ADL. MuscleAlgometry | Within group benefits (p<.001 in 1 trial) but NSS between active groups. In 1 trial splints better (P<.04) than acupuncture at 4 wks, NSS at 12wks. | ||||

Author Commentary:
There is some weak evidence that any of the physiotherapy modalities available are better than no treatment for TMJD and combinations of treatment may be better than single treatments. Within group benefits are usually not supported by between group benefits. All the reviews appraised comment on the lack of scientific rigour and decisive studies.
Bottom Line:
In the absence of any outstandingly robust evidence, any of the numerous treatment modalities for myogenic TMJD seem to have a beneficial effect.
