“…Inzelberg et al (2005) observed improvement in inspiratory muscle strength and endurance and improvement in the perception of dyspnoea in individuals with PD after IMT. There are some studies in the literature evaluating IMT in populations with other neurological diseases, such as ischaemic stroke (Menezes et al, 2016), amyotrophic lateral sclerosis (ALS; Ferreira, Costa, Plentz, Coronel, & Sbruzzi, 2016;Macpherson, Bassile, & Clare, 2016) and multiple sclerosis (MS; Ferreira et al, 2016;Fry, Pfalzer, Chokshi, Wagner, & Jackson, 2007;Klefbeck & Nedjad, 2003), which showed improvement in muscular strength and respiratory function. However, in addition to these, other benefits can be verified in other diseases, such as heart failure (Caruso et al, 2016;Mello et al, 2012) and chronic obstructive pulmonary disease (Basso-Vanelli et al, 2016), in which IMT was able to improve thoracic mobility, increase functional capacity, besides autonomic and peripheral controls, and quality of life.…”
