Criterion Validity of the Isometric Contraction Test for Diagnosis of Axis I DC/TMD Considering Specific Muscles
Background
To determine the validity of the Isometric Contraction Test (ICTest) for the DC/TMD in axis I regarding specific muscles such as the masseter, temporalis and medial pterygoid muscles.
Methods
Forty patients with a diagnosis of TMD axis I of muscle origin and forty healthy controls were evaluated with the ICTest. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (LR+) and negative likelihood ratio (LR−) were determined concerning the DC/TMD on axis I of muscle type, individually assessing the masseter, temporalis and medial pterygoid muscles.
Results
The ICTest achieved a sensitivity ranging from 41% to 88.9% in masseter and temporalis muscles with lower values for the medial pterygoid muscle and when referred myofascial pain subtype was analysed. Specificity remained stable in both situations, the subtype of myalgia and the muscles studied, ranging from 93.4% to 98.7%. The LR values indicated high variability depending on the muscle and type of pain, although LR+ and LR− were ≥ 7.08 and ≤ 0.76%, respectfully, in all cases.
Conclusions
The ICTest is highly specific when studying the masseter, temporalis and pterygoid muscles, with the latest one showing the poorest results. Referred myofascial pain exhibits the lowest validity for all the muscles.
期刊介绍：
Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function.
Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology.
The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
