Influence of Respiratory Muscle Training on Patients’ Recovery after Lung Resection

Abstract

This prospective experimental study aimed to compare effects of 3 different home-based postoperative respiratory muscle training protocols – inspiratory, expiratory and combined, in the patients’ postoperative recovery, regarding safety and respiratory muscle function, pulmonary function, physical fitness, physical activity (PA), dyspnoea and quality of life (QoL). Patients were divided in four groups Usual Care (UCare), inspiratory (IMT), expiratory (EMT) or combined muscle training (CombT) according to group allocation. Significant treatment*time interactions were found for maximal inspiratory pressure (MIP) (p=0.014), sedentary PA (SEDPA) (p=0.003), light PA (LIGPA) (p=0.045) and total PA (p=0.035). Improvements were observed for MIP in CombT (p=0.001), IMT (p=0.001), EMT (p=0.050). SEDPA reduced in EMT (p=0.001) and IMT (p=0.006), while LIGPA increased in both groups (p=0.001), as well as Total PA (p=0.005 and p=0.001, respectively). In UCare, CombT, and EMT, QoL improved only for Usual Activities. In conclusion, the addition of respiratory muscle training to physiotherapy usual care is safe and effective to increase MIP and contribute to improve physical activity. The CombT showed greater improvement on MIP, while IMT compared to EMT, was more effective to improve physical activity.

Efficacy of Respiratory Training in Relieving Postoperative Pain in Patients with Spinal Nerve Root Entrapment Syndrome

“…In addition, previous research has shown that breathing training can alleviate the symptoms of dyspnea and prolong survival time [8]. Respiratory training can relieve pain by guiding patients to consciously prolong the time of spontaneous breathing and controlling abdominal ups and downs to carry out regular breathing exercise [9,10]. Therefore, the purpose of this study was to explore the effect of respiratory training in relieving postoperative pain in patients with spinal nerve root entrapment syndrome.…”

Cancer survivor inspiratory muscle training: systematic review and Bayesian meta-analysis

“…One hundred thirteen studies were excluded for different reasons (see exclusion criteria). Finally, nine studies were included in the review16 31–37 (figure 1).…”

“…Selected studies had been published between 2012 and 2020. Four studies had been conducted before surgery treatment,31–34 another four after surgery35–37 or other treatments,16 and only one during radiotherapy 38. In those studies, 363 patients participated in IMT intervention; 87.4% of them were finally analysed.…”

“…In those studies, 363 patients participated in IMT intervention; 87.4% of them were finally analysed. Type of cancer finally analysed included lung16 32 35–37 and oesophageal31 33 34 38; participants were mainly male (>70%) and aged between 57 and 70 years old.…”

“…One of the selected studies did not include pulmonary or respiratory functions variables36; the rest reported data mainly on inspiratory muscle pressure (MIP),31 33–35 37 38 forced expiratory volume in 1 s (FEV 1 )16 33–35 37 38 and forced vital capacity (FVC) 16 33–35 37. Significant improvements in MIP were observed when IMT was applied before31 33 34 or after surgery treatment,35 37 and only one study in which IMT was performed after surgery found changes in FEV 1 and FEV 1 /FVC 35…”
