Back pain in relation to musculoskeletal disorders in the jaw-face: A matched case–control study

Abstract

Back pain and temporomandibular disorders are both common conditions in the population with influence on the human motor system, but a possible co-morbidity between these conditions has not been fully investigated. The aim of this study was to test the hypothesis of an association between long-term back pain and pain and/or dysfunction in the jaw-face region. Back pain was defined as pain in the neck, shoulders and/or low back. The study-population comprised 96 cases with long-term back pain and 192 controls without back pain. We used a screening procedure, a questionnaire and a clinical examination of the jaw function. The questionnaire focused on location, frequency, duration, intensity and impact on daily life of symptoms in the jaw-face and back regions. The analysis was conducted on 16 strata, matched by age and sex for case vs. control, using Mantel-Haenszel estimates of matched odds ratio (OR) and 95% confidence interval (CI) as well as the corrected Mantel-Haenszel chi(2) test. The overall prevalence of frequent symptoms in the jaw-face region, as reported in the questionnaire, was 47% among cases and 12% among controls. The difference was statistically significant (P<0.0001) with a sevenfold odds ratio (CI: 3.9-13.7). Moderate to severe signs from the jaw region were clinically registered among 49% of the cases and 17% of the controls (P<0.0001, OR: 5.2, CI: 2.9-9.2). The results showed statistically significant associations between long-term back pain and musculoskeletal disorders in the jaw-face and indicate co-morbidity between these two conditions.

Myofascial Trigger Points in the Masticatory Muscles in Patients With and Without Chronic Mechanical Neck Pain

“…In addition, several studies support the presence of trigeminal sensitization in individuals with pain in extracranial areas. [36][37][38] Clinical evidence of segmental sensitization is also supported by animal models where unilateral localized musculoskeletal pain caused sensitization of contralateral segments. 39 Therefore, the existence of latent TrPs in the masticatory muscles may constitute, at least in part, the pathologic basis for the spreading pain to the orofacial region in this population.…”

Comparaison des effets d’une manipulation de l’articulation crânio-cervicale et du rachis thoracique sur la distance interincisives

“…Une étude de cas-témoins sur une centaine de sujets évoque une relation significative entre des douleurs lombaires chroniques et des troubles musculo-squelettiques de la région crânio-mandibulaire [16]. Il semblerait que la prévalence de dysfonctions articulaires temporo-mandibulaires ait augmenté chez des patients douloureux chroniques du dos (que ce soient des douleurs cervicales, dorsales ou lombaires) [16].…”

“…Il semblerait que la prévalence de dysfonctions articulaires temporo-mandibulaires ait augmenté chez des patients douloureux chroniques du dos (que ce soient des douleurs cervicales, dorsales ou lombaires) [16]. Bretischwerdt et al ont montré que l'étirement des muscles ischio-jambiers entraînait également une augmentation significative d'ouverture de la bouche [17].…”

Acute and chronic lumbosacral pain: Topical problems

“…В то же время хорошо известно, что основными факторами риска развития хрони-ческой боли являются психосоциальные причины [29], что боль в спине коморбидна другим хроническим болевым синдромам [30,31], а также психическим нарушениям [32][33][34][35], при этом преморбидные психические расстройства повышают риск развития боли в спине. По нашим данным, дебют хронической боли в спине с несомненного острого эпизода, когда можно было выявить очевидный провоциру-ющий «механический» фактор, отмечался менее чем у чет-верти пациентов.…”
