Amplitude e velocidade dos movimentos mastigatórios em pacientes com doença de Parkinson

Purpose: to characterize the amplitude and speed of masticatory cycles evaluated by electrognathography in one group of elder individuals and to compare these data with those of two other groups of Parkinsons disease subjects. Methods: 42 volunteers participants in this study were divided into three groups: A with 15 volunteers, average age of 62 years, 8females, B with 14 volunteers characterized by a Parkinson’s hypokinesia, average age of 58 years, of which 7 are female, and C with 13 volunteers characterized by a Parkinson’s tremor, with average age of 64 years, being 4 female. It was used the ANOVA test for difference of means with post-hoc Dunnetts contrast or Students t-test, all at 0.05 significance level. Results: there were greater differences between the means of groups A and B in the total number of masticatory cycles (A = 23.13 ± 1.41 B = 18.21 ± 1.70) [p = 0.034] and in the maximum mouth opening amplitudes (A = 34.66 ± 2.04 B = 26.72 ± 2.49) [p = 0.018], lateralization to the right (A = 7.02 ± 0.59 B = 5.80 ± 0.97) P = 0.036] and left (A = 6.44 ± 0.64 B = 3.35 ± 0.80) [p = 0.039]. Conclusion: the elderly group exceeded the means, in the mandibular movement during chewing, of the rigid group of parkinsonians. We may conclude that factors such as parkinsonian stiffness are likely to compromise the chewing of individuals with Parkinsons disease.

Jaw movement in people with Parkinson's Disease

UNLABELLED This study aimed to characterize the amplitude and speed of isolated jaw movements and chewing using electrognathography in a volunteer and to compare these data with those of two other Parkinson Disease (PD) subjects, differentiated by the motor characteristics. METHOD The 3 participants were divided into three categories: one with 1 non-PD volunteer, a second category with 1 volunteer characterized by Parkinsons hypokinesia, and a third with 1 volunteer characterized by Parkinsons tremor. RESULTS There were differences among the three groups; however the most significant was between the non-PD and the PD-rigidity, in the amplitude and speed when performing the jaw movements and chewing. Factors related to the adaptive and compensatory processes derived from rigidity process seemed to better explain the observed changes among the PD groups.

Jaw movement during the speech in children with allergic rhinitis

INTRODUCTION Allergic rhinitis can cause changes in stomatognathic functions, which may alter the mandibular dynamics. Electrognathography is used in the recording of jaw movements, making it valid for analysis of movements in speech. PURPOSE To characterize the amplitude and velocity of jaw movements during speech in children with and without allergic rhinitis. METHODS The sample consisted of 32 children aged 7-12 years, treated at a university hospital, divided into two groups: one with rhinitis and the other without rhinitis. To capture the jaw movements during speech, we used an electrognathography with the aid of a list of phonetically balanced figures. For the analysis of data, we used, in addition to descriptive statistics, nonparametric tests, Spearman correlation coefficient and the Mann-Whitney test, with a significant value of p=0.05. RESULTS No significant difference was observed in jaw movements between groups, with values of p equals to 0.175, 0.650, and 0.462 for amplitude and jaw opening and closing velocity, respectively. However, a strong correlation was observed between the variables velocity and amplitude of mouth opening, being slightly higher in the group of children with allergic rhinitis. CONCLUSION The amplitude and velocity of jaw movements are found to be similar in children with and without allergic rhinitis, and a correlation exits between these variables. In addition, they were more heterogeneous in the group without allergic rhinitis.

Chewing preference and its relationship with postural muscular electric potential

Methods: fifty-five volunteers (41 women and 14 men; average age of 26 years) were evaluated by Odontology (determining the type of dental occlusion), by a speech therapist (determining the chewing side preference) and by a physiotherapist (evaluating the postural muscular electrical potential). The three professionals had no communication regarding the evaluations, in order to keep the study partially blind. For chewing preference electrognatography was used for muscles: sternocleidomastoid, upper trapezium, gluteus medius and tibialis anterior, bilaterally, in static orthostatic posture. Results: there was statistical significance for the muscular electrical potential of the sternocleidomastoid and anterior tibial, when there was right chewing preference (p=0.030 for both) and left chewing preference (p=0.0028 and p=0.0020, respectively). In alternate bilateral chewing there was tendency to symmetry of postural muscular electrical activation, in all muscles. Conclusion: there was presence of asymmetry of postural muscular electrical activation in the sternocleidomastoid and tibialis anterior, when chewing side preference was at right or left. In the presence of alternate bilateral mastication, there was tendency of symmetry of postural muscular electrical activation for all studied musculatures.

Assessment of electrical activity in the supra and infra hyoid muscle in individuals with type 2 diabetes mellitus

Materials and methods Sample was composed of thirty female adults, aged between 40 and 60 years, distributed in Diabetes group and Control group and they were submitted to a electromyography exam with electromyography MIOTEC (Rio Grande do Sul, Brazil) connected to a notebook SAMSUMG brand provided the Miotool 200 software, using windowing 32 and gain equal to 2000 for each channel. An electrode reference and three channels connected to active sensors with connection SDS500 by claws were used. The signal analysis was performed with the Miograph 2.0 software. For normalization of the supra-hyoid group (HS) swallowing incomplete maneuver and the infra-hyoid (IH), the tongue retracted technique was used. Then, it was performed the catchment of the muscular electrical activity through the rest moment following by the evaluation during vowel/e/ vocalization and the usual speech. It had been used the t test to calculate the differences between the averages of electrical activity of the groups evaluated.

Amplitude and speed of masticatory movements in total laryngectomy patients

INTRODUCTION Laryngectomy is a surgical procedure that aims to remove the hyoid bone and the larynx and its muscles; it is inferred that a destabilization of the hyoid-mandibular axis will occur, consequently changing chewing. OBJECTIVE To characterize the amplitude and speed of chewing in laryngectomies and to compare them with two groups of non-laryngectomized individuals differentiated by age. METHOD 72 volunteers were divided into three groups: (A) 32 volunteers, mean age 22.3 years, 17 females; (B) 20 volunteers, mean age 53.2 years, 10 females, and (C) 20 volunteers who underwent total laryngectomy, mean age 61.5 years, one female. Electrognathography, a method that tracks and measures millimeter jaw movements, was used for evaluation. RESULTS Significant differences were observed between groups A and C in masticatory amplitude and speed. CONCLUSION Age, and adaptive and compensatory changes appear to explain chewing better than factors related to total laryngectomy.Introdution: Laryngectomy is a surgical procedure that aims to remove the hyoid bone and the larynx and its muscles; it is inferred that a destabilization of the hyoid-mandibular axis will occur, consequently changing chewing.
