Factors associated with mandibular function impairment in people with Parkinson's disease during social isolation due to COVID-19

ABSTRACT Purpose: to analyze factors associated with mandibular function impairment in people with Parkinson's disease during social isolation due to COVID-19. Methods: this cross-sectional, quantitative, analytical study used a database with 115 records of patients presented with this condition (obtained via telemonitoring in a research conducted in 2020) and assessed sociodemographic aspects and the Mandibular Function Impairment Questionnaire (MFIQ). The variables addressed in the associations were sex, age, marital status, denture use, disease duration, and daily levodopa dose. Results were obtained with the Fisher´s exact test, with the significance level set at p < 0.05. Results: after analyzing the database, the final sample comprised 62 eligible records - 61% were males, 79% were above 60 years old, 63% wore dentures, and 93% had low severity of mandibular function impairment, according to MFIQ. No significant associations were found between the study variables and MFIQ (p < 0.05). Conclusion: the degree of mandibular impairment was low, and the study variables were not associated with mandibular function impairment in patients presented with Parkinson´s disease, during social isolation, due to COVID-19.

Efeito imediato da estimulação auditiva rítmica nos parâmetros espaços-temporais da marcha de idosos sedentários: um estudo piloto / Immediate effect of rhythmic auditory stimulation on the spatio-temporal parameters of gait in old people: a pilot study

Resumo Objetivos Avaliar o efeito imediato da estimulação auditiva rítmica (EAR) com música sobre os parâmetros espaços-temporais da marcha em idosos sedentários e analisar possíveis interações com os episódios de quedas. Métodos Estudo piloto de intervenção com idosos sedentários (n=15), idade ≥ 60 anos, ambos os sexos, independentes na marcha. Adicionalmente, os idosos foram divididos em dois grupos, caidores (n=5) e não caidores (n=10), baseado no histórico de quedas no último ano. A avaliação dos parâmetros espaços-temporais da marcha foi realizada através do teste de Caminhada de 10 metros executado em marcha livre (T0), repetido com suporte da EAR com música (T1) e executado em marcha livre novamente (T2). Para a análise dos dados, foram utilizados a ANOVA de medidas repetidas e a ANOVA (two-way) para comparação entre os grupos, com o post hoc de Tukey. O tamanho do efeito das intervenções também foi calculado. Resultados Houve redução significativa do tempo e do número de passos e um aumento da velocidade da marcha (p<0,0001; com efeito grande) entre os momentos T0-T1 e T0-T2. Ambos os grupos caidores e não caidores apresentaram redução significativa do tempo e do número de passos (p<0,0001) e aumento da velocidade (p<0,0001), mas apenas na variável cadência houve efeito do grupo e da interação tempo e grupo. Conclusão Verificou-se um efeito imediato positivo do uso da EAR nos parâmetros espaços-temporais da marcha de idosos sedentários com maior efeito na cadência de idosos não caidores.

Abstract Objectives Evaluate the immediate effect of rhythmic auditory stimulation (RAS) with music on the spatio-temporal parameters of gait in sedentary old people and analyze possible interactions with episodes of falls. Methods Pilot intervention study with sedentary old people (n= 15), age ≥60 years, both sexes, independent in gait. Additionally, participants were divided into two groups, fallers (n= 5) and non-fallers (n= 10), based on the history of falls in the last year. The evaluation of the spatio-temporal parameters of the gait was performed using the 10-meter walk test performed with free walking (T0), repeated with RAS with music (T1), and without RAS again (T2). For data analysis, repeated measures ANOVA and two-way ANOVA were used for comparison between groups, with Tukey's post hoc. The effect size of the intervention was also calculated. Results There was a significant reduction in time and number of steps and an increase in walking speed (p<0.0001; with great effect) between moments T0-T1 and T0-T2. Both the faller and non-fallers groups showed a significant reduction in time and number of steps (p<0.0001) and an increase in speed (p<0.0001), but only in the cadence variable was there an effect of the group and of time and group interaction. Conclusion There was an immediate positive effect of the use of RAS on the space-time parameters of gait in sedentary old people, with a greater effect on the cadence of non-falling old people.
