Methods to normalize surface electromyography in respiratory muscles: Is it similar between amyotrophic lateral sclerosis and healthy people?

The normalization process is important to determine the best approach for normalizing electromyographic signals from respiratory muscles in healthy subjects and those with ALS. The aim of this study is to compare different methods of normalizing the sEMG signal of respiratory muscles in both healthy subjects and those with Amyotrophic Lateral Sclerosis (ALS). This cross-sectional study was conducted in 67 subjects (50 healthy and 17 with ALS).

Supervised exercise protocol for lower limbs in subjects with chronic venous disease: an evaluator-blinded, randomized clinical trial.

Background: Chronic venous insufficiency (CVI) causes pathophysiological changes in the lower-limb muscles, particularly the calf muscles, and limits ankle range of motion (ROM). These changes reduce functional activities and decrease quality of life (QOL). Although several studies have shown the benefits of exercise (strengthening the calf muscles to improve calf-muscle pumping and QOL) in patients with CVI, few studies are randomized controlled trials.

Association between quality of life, severity of asthma, sleep disorders and exercise capacity in children with asthma: a cross-sectional study.

Objective: To assess the association between quality of life, asthma severity, sleep disorders and exercise capacity in children with asthma.

Methods: We evaluated 45 children with asthma of both sexes aged between 7 and 12 years, diagnosed by a pediatrician/pulmonologist and classified according to the IV Brazilian Guidelines for Asthma Management: severity (intermittent/mild and moderate/severe) and control (controlled, partially controlled and uncontrolled). Quality of life (QoL), presence of sleep disorders and exercise capacity were respectively assessed using the following instruments: Pediatric Asthma Quality of Life Questionnaire (PAQLQ); Sleep Disturbance Scale for Children (SDSC); and six-minute step test (6MST).

APPLICABILITY OF A GENERIC QUESTIONNAIRE FOR QUALITY OF LIFE ASSESSMENT FOR ASTHMATIC CHILDREN.

Objective: To determine the applicability of the generic instrument Pediatric Quality of Life Inventory (PedsQL 4.0) to assess health-related quality of life of asthmatic children compared to the specific instrument Pediatric Asthma Quality of Life Questionnaire (PAQLQ).

Methods: This research involved the evaluation of 30 children aged seven to eleven years, who had been diagnosed with asthma for at least six months prior to research.
