Electromyographic activity of the jaw muscles and mandibular kinematics in young adults with theoretically ideal dental occlusion: Reference values

Introduction: Bruxism is an involuntary parafunctional habit performed unconsciously during sleep by the jaw muscles in which the tooth rows are pressed against each other and move horizontally. The symptoms in the oral cavity are slightly elusive which makes it difficult to diagnose.Aim: The aim of this study was to analyze the occlusion and disocclusion times in young adults affected by bruxism compared with healthy subjects.Materials and methods: Thirty-four patients (15 men and 19 women) aged between 20-25 years were included in the study. They were allocated into two groups: group 1 – controls (n=13), and group 2 – patients who reported clenching or grinding their teeth (n=21). The study was conducted using a T-Scan Novus occlusion diagnostic device. The results obtained for the occlusion and disocclusion times were analyzed using the latest version of the T-Scan system software (ver. 9.1). The values for occlusion and disocclusion times of all subjects were recorded in the T-Scan.Results: The occlusion times in the control group were found to be longer than those in the bruxism group. The disocclusion times of the subjects in group 1 were found to be shorter than those in group 2.Conclusions: The T-Scan system makes it possible to quantify the occlusion and disocclusion times, which helps to diagnose an initial form of bruxism in individuals at a young age.

BackgroundVery few objective data exist regarding aerobic performance in young people with cerebral palsy (CP). The characterization of aerobic fitness could provide baseline and outcome measures for the rehabilitation of young people with CP.ObjectiveThe objective of this study was to provide reference values for aerobic fitness in a group of children, adolescents, and young adults who had CP and who were classified at Gross Motor Function Classification System (GMFCS) level I or II. Data were collected with 10-m shuttle run tests.DesignThis investigation was a cross-sectional observational study conducted between August 2008 and June 2009.MethodsReference values were established using data from a total of 306 children, adolescents, and young adults who had CP, who were 6 to 20 years old, and who were recruited from 26 rehabilitation centers in the Netherlands, Switzerland, Australia, Canada, and the United States. A total of 211 participants were classified at GMFCS level I (mean age=12.2 years, SD=3.0), and 95 were classified at GMFCS level II (mean age=12.4 years, SD=3.2); 181 were male, and 125 were female. Aerobic fitness was reflected by the level achieved on the 10-m shuttle run tests.ResultsOn the basis of a total of 306 assessments from the 10-m shuttle run tests, 4 reference curves were created.LimitationsThe limitation of this study is the cross-sectional nature of the design.ConclusionsThis study provided height-related reference values for aerobic fitness in children, adolescents, and young adults who had CP, who were 6 to 20 years old, and who were classified at GMFCS level I or II. Generalized additive models for location, scale, and shape were used to construct centile curves. These curves are clinically relevant and provide a user-friendly method for the prediction of aerobic fitness in young people with CP.

Foot Posture

Background. The foot posture index (FPI) is a valid, reliable, and multidimensional method for determining foot posture in a wide range of clinical settings. To date, no normative data of healthy young adults in Saudi Arabia have been available for comparison and reference. Hence, this study is aimed at establishing the FPI reference values, gender, and side differences of FPI and their association with anthropometric determinants, balance, functional mobility, and hypermobility. Methods. FPI was assessed in 581 (291 men and 290 women) healthy young adults aged 18–25 years. The FPI range was obtained for both feet as the sum of the scores (–2, –1, 0, 1, and 2) given to each criterion: (–1 to –12) supinated foot, (0 to +5) neutral foot, and (+6 to +12) pronated foot. The study furthermore assessed the balance using a near tandem balance test, functional mobility by stair ascent and descent test, and joint hypermobility via the Beighton scale. Results. The average FPI score was 2.76 ± 5.23 for all subjects, 2.98 ± 5.02 for men and 2.55 ± 5.43 for women. Neutral foot posture was most frequent in this study (52.9%). A higher proportion of women had pronated (21.0%) and supinated (11.7%) feet than men which were 16.8% and 10.3%, respectively. This study also confirmed that side differences were found to be significant ( p value < 0.001), whereas gender differences were significant only in the normal, pronated, and supinated foot groups. Conclusion. The most common foot posture in both genders was ranged from neutral to slight pronation. We also found a correlation between balance with FPI in the supinated and hypersupinated foot groups, functional mobility with FPI of pronated and supinated foot groups, and joint hypermobility with FPI of the hyperpronated foot group.
