STUDY DESIGN Observational longitudinal study. OBJECTIVE To establish the normal variation over time for active and passive cervical range of motion (ROM) measured with the Flock of Birds electromagnetic tracking system (FOB). SUMMARY OF BACKGROUND DATA Data about normal variation of cervical ROM over time are scarce but important for the interpretation of study results. METHODS Forty-eig...

The analysis of movement dysfunction often requires that inferences be made about the muscle forces which occur during motor task performance. Physiotherapists probably use a range of different models of analysis to make inferences about such forces. These models differ in the degree to which they invoke simplifying assumptions about the non-muscle forces acting on body segments. In some circum...

This study aimed to examine the effects of chin cup therapy on the temporomandibular joint (TMJ) disc position and configuration with magnetic resonance imaging (MRI). Twenty-five individuals ranging in age from 5 to 11 years were evaluated. The treatment group consisted of 15 subjects (10 females and five males) with prognathic facial structures, while the control group comprised 10 subjects (...

The aim of this study was to register and measure lower jaw movements, to analyse the measured length of opening and closing movements and to analyse the rotational mandibular capacity during the maximal opening of the mouth in the position of centric relation. Our objective was to determine the average values for each mandible and temporomandibular joint movement, as well as to determine the a...

Characteristic bone profile of the temporomandibular joint (TMJ) develops and grows up to late teenage years.[1] TMJ bone structures alter their morphology according to functional and pathological conditions throughout life. In this study, differences in TMJ skeletal morphology between children and young adults (aged between 20 and 24 years) were compared. [2] The results of this study show the...

OBJECTIVE Tinnitus is frequently associated with temporomandibular joint (TMJ) dysfunction. However, the nature of the relationship is not fully understood. Here the authors compared 30 patients with a confirmed diagnosis of temporomandibular joint dysfunction and tinnitus to a group of 61 patients with tinnitus but without any subjective complaints of TMJ dysfunction with respect to clinical a...

Background The aetiology of temporomandibular joint disorders (TMD) is multifactorial, whereas occlusal disharmony is one of the predisposing factors. Researchers still discuss the relation between occlusion and TMD. Objective The study aims to investigate the relation between static occlusal parameters and TMD clinical symptoms using T-Scan II analysis system. Material and methods The samp...

BACKGROUND Joint range of motion might affected by some factors like laxity and increase joint mobility. Generalized joint hypermobility and temporomandibular joint hypermobility (TMJH) are reported as risk factors for temporomandibular disorders. The aim of this study was to survey the etiological factors of TMJH and its relations to habitual status. MATERIALS AND METHODS In this cross-secti...
