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

ABSTRACT: 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). The electrical activity of the sternocleidomastoid (SCM), scalene (ESC), diaphragm (DIA), parasternal (PS), external intercostal (EI), external oblique (EO), and rectus abdominal (RA) muscles were analyzed during maximal inspiratory pressure maneuvers (MIP), maximal nasal inspiratory pressure (SNIP), maximal expiratory pressure (MEP), and maximal vol
