<h3>Importance</h3> Apathy, characterized by diminished will or initiative and one of the most prevalent neuropsychiatric symptoms in individuals with Alzheimer disease, is associated significant caregiver burden, excess disability, increased medical costs, mortality. <h3>Objective</h3> To measure whether methylphenidate compared placebo decreases severity apathy disease. <h3>Design, Setting, participants</h3> This multicenter randomized placebo-controlled clinical trial was conducted from...
OBJETIVO: Descrever o padrão respiratório e movimento toracoabdominal de indivíduos saudáveis considerando a idade sexo. MÉTODOS: Foram estudados 104 com idades entre 20-39, 40-59 60-80 anos, 41 homens 63 mulheres, índice massa corporal valores espirométricos normais. A pletismografia respiratória por indutância foi utilizada para mensurar, durante repouso em decúbito dorsal, as seguintes variáveis: volume corrente (Vc), frequência (f), ventilação minuto (VE), razão tempo inspiratório total...
Optoelectronic plethysmography (OEP) is an innovative method of indirect measurement pulmonary ventilation, capable breath-by-breath, three-dimensional, real time assessment absolute lung volumes and their variations in the three compartments chest wall (pulmonary rib cage, abdominal abdomen). OEP allows variables breathing pattern, asynchrony, contribution each compartment hemithorax to tidal volume.To review literature on following aspects related OEP: history, operating principle,...
This study compared the passive stiffness of wrist flexors and strength extensors in three different positions (30 degrees flexion, neutral, 30 extension) between children with cerebral palsy (CP) typically developing (TD) comparison children. It also examined associations these characteristics manual function CP. Eleven spastic hemiplegic CP (six females, five males; mean age 8y 5mo [SD 1y 8mo], range 6-11y) 11 TD children, matched for sex, took part this study. Passive muscles was measured...
Eccentric cycling may present an interesting alternative to traditional exercise rehabilitation for patients with advanced COPD, because of the low ventilatory cost associated lengthening muscle actions. However, due damage and soreness typically eccentric exercise, there has been reluctance in using this modality clinical populations. This study assessed feasibility applying protocol, based on progressive overload, six severe COPD aim minimizing side effects maximizing compliance. Over 5...
BACKGROUND: The mechanisms underlying breathing exercises have not been fully elucidated. OBJECTIVES: To evaluate the impact of four on (diaphragmatic breathing, inspiratory sighs, sustained maximal inspiration and intercostal exercise) pattern thoracoabdominal motion in healthy subjects. METHOD: Fifteen subjects both sexes, aged 23±1.5 years old with normal pulmonary function tests, participated study. were evaluated using optoelectronic plethysmography system a supine position trunk...
Optoelectronic plethysmography (OEP) has been used to measure changes in chest wall volume and its compartments. However, literature lacks research on reliability. The purpose of this study was evaluate the intra-rater inter-rater reliability OEP. Thirty-two healthy subjects were evaluated at rest during submaximal exercise a cycle ergometer. following variables assessed: (VCW); percentage contribution pulmonary rib cage (V(rcp)%), abdominal (V(rca)%), (V(rc)%) abdomen (Vab%); end-expiratory...
Chest wall volumes and breathing patterns of 13 male COPD patients were evaluated at rest during inspiratory loaded (ILB). The sternocleidomastoid (SMM) abdominal muscle activity was also evaluated. main compartment responsible for the tidal volume ILB abdomen. During exhibited, in addition to increases ratio time total respiratory cycle minute ventilation, (p<0.05) chest by an increase abdomen as a result improvement end without changing on expiratory volume. SMM increased 63.84% 1.94% ILB....
The effects of non-invasive ventilation (NIV) on the breathing pattern and thoracoabdominal motion patients with amyotrophic lateral sclerosis (ALS) are unknown.1) To analyze influence NIV chest wall volumes assessed by optoelectronic plethysmography in ALS 2) to compare these parameters supine sitting positions those healthy individuals (without NIV).Nine were evaluated position using NIV. In addition, nine both positions. Statistical analysis was performed paired Student t-test or Wilcoxon...
The measurement of maximal respiratory pressure (MRP) is a procedure widely used in clinical practice to evaluate muscle strength through the inspiratory (P(Imax)) and expiratory (P(Emax)). Its applications include diagnostic procedures evaluating responses interventions. However, there great variability equipment procedures. Understanding impacts characteristics different interfaces can augment repeatability this method help establish applicable predictive equations. aim study was influence...
While transcranial direct current stimulation (tDCS) can enhance aspects of memory in patients with mild cognitive impairment (MCI) and Alzheimer disease (AD), there has been wide variability both the placement tDCS electrodes treatment response. This study compared effects bifrontal (anodal over dorsolateral prefrontal cortices), bitemporal temporal sham on performance MCI AD.Seventeen diagnosed or AD received 3 sessions anodal (bifrontal, bitemporal, 2 mA for 20 minutes; sham) random...
INTRODUÇÃO E OBJETIVO: O teste de esforço com protocolo rampa é descrito como o que mais se adéqua à condição física indivíduos insuficiência cardíaca (IC). Porém, não há padronização descrita sobre incrementos velocidade e inclinação.

Background: The manovacuometer is a simple and non-invasive test to measure respiratory muscle strength. Guidelines recommend the use of digital due its high accuracy. Aims: purpose this study was assess test-retest reliability concurrent validity developed at Federal University Minas Gerais (UFMG, Belo Horizonte, Brazil). Methods: 30 healthy subjects were assessed (20-30 years old, normal body mass index pulmonary function) using UFMG MicroRPM ® (Micro Medical, UK). following variables...

Abstract Background Transcranial direct current stimulation (tDCS) is a non-invasive type of brain that uses electrical currents to modulate neuronal activity. A small number studies have investigated the effects tDCS on cognition in patients with Mild Cognitive Impairment (MCI) and Alzheimer’s disease (AD), demonstrated variable effects. Emerging evidence suggests most effective when applied active circuits. Aerobic exercise known increase cortical excitability improve network connectivity....
