Relationship between PEmax and PImax for healthy individuals (A) and subjects with neuromuscular diseases (NMDs) among the pathologies (B). Relationship between PEmax and PImax for healthy individuals (A) and subjects with neuromuscular diseases (NMDs) among the pathologies (B). Also shown is the PEmax/PImax ratio relationship to age in healthy subjects (C) and subjects with NMDs (D). Open shapes are females, and closed shapes are males. ALS = amyotrophic lateral sclerosis; MG = myasthenia gravis; MD = myotonic dystrophy. In C, the horizontal lines represent the majority concentration of healthy subjects (1.5 ± 0.5) They are repeated in D to compare the distribution of NMD subjects. Guilherme Fregonezi et al.
