Methods to normalize surface electromyography in respiratory muscles: Is it similar between amyotrophic lateral sclerosis and healthy people?
PLoS One
December 2024
Article Synopsis
- The study focuses on comparing methods for normalizing electromyographic signals from respiratory muscles in both healthy individuals and those with Amyotrophic Lateral Sclerosis (ALS).
- 67 subjects (50 healthy and 17 with ALS) were analyzed during various breathing maneuvers to measure muscle activity.
- The results indicated that for healthy individuals, maximal voluntary isometric contraction (MVIC) was the best method for assessing inspiratory muscle activity, while in ALS patients, the maximum nasal inspiratory pressure (SNIP) maneuver was more effective for inspiratory muscle normalization.

: This study aimed to analyze the impact of seated, 45° inclined, and supine positions on respiratory muscle strength (Maximal Inspiratory Pressure-MIP, Maximal Expiratory Pressure-MEP, Sniff Nasal Inspiratory Pressure-SNIP and Sniff Nasal Expiratory Pressure-SNEP) and the electrical activity of respiratory muscles in healthy adults. Ten healthy subjects were evaluated. : Personal, anthropometric data (weight, height, BMI) and lung function (spirometry) were collected, followed by random assessments of inspiratory (MIP, SNIP) and expiratory (MEP, SNEP) muscle strength.

This longitudinal case series included five evaluations from January 2019 to June 2021. The first and second assessments were performed in person and consisted of pulmonary function, respiratory muscle strength, functionality (ALS Functional Rating Scale-Revised [ALSFRS-R]) and disease staging (King's College criteria).

We assessed non-invasively the fatigue and recovery of inspiratory rib cage muscles during two respiratory endurance tests in healthy individuals.
Methods: The sniff nasal inspiratory pressure (SNIP) was assessed before and after two respiratory endurance tests: normocapnic hyperpnea (NH) and inspiratory pressure threshold loading (IPTL).
