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.
