Smartphone-based evaluation of static balance and mobility in type 2 Diabetes.

It was compared smartphone-based measurements of static balance control and mobility of elderly population with and without type 2 diabetes mellitus (DM2). The present cross-sectional study investigated 73 participants grouped in a control group (n = 36) and a DM2 group (n = 37). Smartphone's built in inertial sensors were used to record inertial changes of the participants during static balance and mobility (Timed Up and Go test - TUG) tasks. The inertial variations as a function of the time were analyzed and compared between groups. Both groups were matched in age, body mass index, male-female proportion, but DM2 group had significant larger fasting glucose than control group. Additionally, DM2 group had worst static balance control with open and closed eyes than the controls (p < 0.05) as well as they also had longer duration to execute the different events of the mobility test than the controls (p < 0.05). DM2 patients had decline of motor functions compared to controls and the use of bult-in sensors of smartphones was feasible to identify these functional impairments. The easy access of smartphones could be improving the screening of functional impairments in DM2 patients.

Efeitos crônico da prática do exercício físico na variabilidade da frequência cardíaca em idosas com diabetes mellitus / Chronic effects of physical exercise on heart rate variability in elderly with type 2 diabetes mellitus

O diabetes mellitus tipo 2 (DM2) é uma doença crônico-degenerativ a n ão t ran smissív el, caracterizada pela hiperglicemia que acomete cada vez mais a população idosa, principalmente, devido ao estilo de vida. Os sintomas da doença envolvem algumas complicações fisiológicas, dentre elas ex iste a possibilidade de desenvolvimento da neuropatia autonômica cardiovascular, que comumente acomete o diabético com a diminuição da variabilidade da frequência cardíaca (VFC). Levando assim, a uma insuficiência cardíaca que pode comprometer de forma severa a vida do diabético. Sendo assim, o objetivo foi analisar o efeito crônico da prática do exercício físico em idosas com DM2 baseado nos parâmetros da VFC. Para que a pesquisa fosse realizada um grupo de 30 idosas foi selecionado aleatoriamente, sen do divididos em três grupos de 10 voluntárias: grupo diabético ativo (GDA), grupo diabético sedentário (GDS) e grupo controle (GC), para ambos os grupos foram coletados as seguintes variáveis: idade, estatura, massa corporal, IMC, gordura corporal relativa e VFC. Os resultados demonstraram que ido sas GDA (870,6 ± 55,3 ms) tiveram uma menor média do intervalo RR e pode demonstrar que com a pratica regular de atividade física é possível retardar e/ou evitar quando comparado ao GC (788,4 ± 27,7 m s) as possíveis complicações cardíacas que acometem ao GDS (874,3 ± 45,7 ms). Diante do exposto acr edita-se que o exercício físico foi determinante para o resultado encontrado na VFC, principalmente, a m édia do intervalo RR no que tange estratificar idosas que possuem diabete tipo 2...(AU)

Type 2 diabetes mellitus (DM2) is a non-transmissible chronic degenerative disease characterized by hyperglycemia that increasingly affects the elderly population, mainly due t o lifesty le. The symptoms of the disease involve some physiological complications, such as, the possibility of developing autonomic cardiovascular neuropathy, which commonly affects the diabetic with the reduction of heart rate variability (HRV). This leads to heart failure that can severely comprom ise th e life o f th e diabetic. Therefore, the aim of this study is to analyze the chronic effect of physical exercise practice o n elderly DM2 based on the parameters of heart rate variability (HRV). In order to carry out the research , a group of 30 elderly women was randomly selected and divided into three groups of 10 volunteers: active diabetic group (GDA), sedentary diabetic group (GDS) and control group (CG). Fo r bo th group s were collected the following variables: age, height, body mass, BMI, relative body fat and HRV. Although t he literature showed that elderly GDA (870.6±55.3 ms) had a lower mean RR interval sh o win g t hat wit h regular practice of physical activity it is possible to delay and/or avoid when compared to GC (788.4±27.7 ms) the possible cardiac complications that affect GDS (874.3 ± 45.7 ms). In conclusio n, th e p h ysical exercise was determinant for the HRV result, especially, the mean RR interval in th e st ratificatio n o f elderly women with type 2 diabetes...(AU)
