La prévalence des dysfonctions somatiques cervicales (DSC) est temporairement augmentée durant le traitement orthodontique. L’objectif de cette étude est de rechercher les facteurs prédictifs des DSC inhérents au patient et au traitement. Matériel et méthodes : Nous avons réalisé une étude rétrospective comparative sur 68 patients en cours de traitement multi-attache entre un groupe ayant développé des DSC sévères versus un groupe témoin (DSC absentes, légères à modérées). Les critères étudiés étaient la typologie verticale et la classe molaire, le disjoncteur, le ressort ouvert, les cales de surélévation, les extractions. Nous avons effectué une étude uni- et multivariée. Résultats : Les facteurs de risque pourvoyeurs de DSC sont l’hypo ou l’hyperdivergence, la classe II molaire, les cales de surélévation molaire, les ressorts ouverts. Le disjoncteur serait protecteur. Les extractions constituent un facteur non significatif. Conclusion : L’étude corrobore l’importance de la classe I molaire et de la normodivergence. Une étude complémentaire est nécessaire pour évaluer si ce sont les dispositifs de traitement ou les caractéristiques diagnostiques qu’ils traitent qui sont reliés aux DSC.
IntroductionSwimming is a very popular sport practiced by million individuals worldwide. Among many physical activities, it is a great form of all-round exercise. When reasonably practiced, it appears to be a good activity in order to be more active and to stay healthy, whatever the age or ability [1]. It is a cyclic, highly repetitive sport combining endurance, velocity, strength, power, and control in a non-weight-bearing environment with important resistive forces. Propulsion is mainly driven by the upper body with repetitive overhead movements. AbstractContext: Shoulder pain is one of the most frequent reported complaints in intensive competitive swimming. The so-called 'swimmers' shoulder' has been widely explored and has been reported sometimes without specifi c reference to contributing mechanisms or structures. Somatic dysfunction is defi ned as an impaired or altered function of related components of the somatic system and may appear in the early stage of pain feeling.Aim: To evaluate somatic dysfunctions in a group of young competitive swimmers with and without shoulder pain and its relationship with the shoulder's mobility along with the effi cacy of an osteopathic manipulative treatment (OMT) on shoulder's mobility, pain, and comfort of swimming.Material and method: 20 competitive swimmers (14.6 ± 1.3 ys; 11.6 ± 2.4 hs.wk-1) were divided into two groups, with and without shoulder pain (SPG/CG). Before and after light touch/ OMT, and 1 week later, somatic dysfunctions, shoulder's range of mobility, pain, and swimming comfort were assessed by 2 independent osteopaths. Results: Somatic dysfunctions were observed in both groups without signifi cant differences in the number or localization and were independent of severity of pain. In the SPG, pain decreased signifi cantly after OMT (6.1 ± 1.9 vs. 3.9 ± 1.8; p = 0.001) and remained stable 1-week later (P = NS). Shoulder's mobility was lower on the aching shoulder in the "shoulder pain" group when compared to the control group on fl exion and abduction tests but not on extension or adduction tests. Following OMT, only abduction improved when compared to light touch. Comfort in swimming was reported as "better" in both OMT/light touch groups. Conclusion:There is no difference between light touch and OMT as both decreased pain and increased comfort in swimming but abduction range of motion only improved in the OMT group.
