Purpose: to verify the existence of an association between the degree of spasticity, the level of motor function and wide topographical classification of CP children with amplitude and time parameters of electromyographic activation of temporalis (AT) and masseter (MA) muscles. Methods: muscle activity during chewing task was evaluated in fifteen children with CP. The clinical instruments used were the Modified Ashworth Scale for spasticity, the Gross Motor Function Classification System (GMFCS) for gross motor function. We analyzed the parameters of muscular symmetry and time of active and inactive period of the masticatory cycle. Results: there was an association between the level of motor function and the symmetry of the MA, between the highest degree of spasticity and decrease in the inactive period and increase in the active period of the masticatory muscles and between the topographical classification and symmetry of the MA and the symmetry of the AT. Conclusion: the symmetry and the time of activation of AT and MA should be considered during therapy of oral motor function of CP children. [ABSTRACT FROM AUTHOR]

Introduction: assart-day life habits have led to a more sedentary lifestyle, contributing to increased obesity. In view of these changes, it is necessary to understand whether the flexibility of the individual has also been influenced. Objective: to investigate the influence of sex, sedentary life-style and nutritional status on the flexibility of elementary school children. Methods: 60 children of both sexes aged five to 14 years were divided into a normal flexibility group (n = 21) and a reduced flexibility group (n = 39). Flexibility was evaluated by photogrammetry using the straight leg raise test, considering the leg angle. The physical activity level was evaluated using the Physical Activity Questionnaire for Older Children, and nutritional status was assessed by Body Mass Index for age and sex. Results: the normal flexibility group and the reduced flexibility group presented no significant differences regarding age, weight or height (p > 0.05). No differences were found (p > 0.05) in leg angle between the active and sedentary groups, the obese and nonobese or between males and females. Conclusions: sex, sedentary lifestyle and nutritional status exercized to influence on the flexibility of students. [ABSTRACT FROM AUTHOR]

The aim of this study was to analyze the symmetry of the electromyographic (EMG) activity of the temporalis, masseter, and sternocleidomastoid (SCM) muscles in volunteers divided into a control group and a temporomandibular disorder (TMD) group. The surface EMG recordings were made during mandibular rest position, maximal intercuspal position, and during the chewing cycle. Normalized EMG waves of paired muscles were compared by computing a percentage overlapping coefficient (POC). The difference between the groups and between the static and dynamic clenching tests was analyzed through repeated measures, ANOVA. Symmetry of the temporalis, masseter, and SCM muscles activity was smaller in the TMD group compared to the control group. The mandibular postures were also significantly different among themselves. The asymmetric activation of jaw and neck muscles was interpreted as a compensatory strategy to achieve stability for the mandibular and cervical systems during masticatory function.
