Brief Summary:
COVID 19 has become a pandemic and has led to high demand on healthcare systems. It can cause a severe acute respiratory syndrome (SARS CoV-2) which leads to a long hospital stay, developing important functional damage and making hospital discharge difficult. Elderly, obese and people with chronic diseases are more susceptible to contracting the disease, this profile of patients already has a predisposition for respiratory muscle weakness and in this context, after clinical stability, it is still necessary in a hospital environment to approach respiratory and motor physiotherapy. to optimize the recovery of these patients. Objective: Improved breathing, functionality, exercise capacity and muscle strength in non-critical patients. Method: Prospective randomized clinical study where one group received motor and respiratory physiotherapy and the other group performed the same therapy associated with inspiratory muscle training. Results: The findings will be compared before and after the approach and will be presented in graphs and tables. Statistical tests will be used considering a significance level of 5%.

Condition or disease Intervention/treatment Phase
Covid19 Respiratory Disease Device: power breathe Not Applicable

Detailed Description:
Prospective clinical study in patients with COVID-19 admitted to a non-critical unit of a tertiary hospital. They were randomized into a group that received motor and respiratory exercises and another group that received the same exercises associated with respiratory muscle training.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 55 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Only patients with respiratory muscle weakness that were considered as the maximum inspiratory pressure value (less than or equal to 60% of the predicted value) entered for randomization. Stratified randomization was performed in which the impaired chest tomography (absent, less than 50% or greater than 50%) was taken into account to be randomly allocated to the groups.
Masking: Single (Investigator)
Masking Description: Stratified randomization was performed in which the impaired chest tomography (absent, less than 50% or greater than 50%)
Primary Purpose: Treatment
Official Title: Efects of Inspiratory Muscle Training in Patients With COVID-19 After Acute Phase. Prospective Study
Actual Study Start Date : June 1, 2020
Actual Primary Completion Date : October 10, 2020
Actual Study Completion Date : October 23, 2020

Arm Intervention/treatment
No Intervention: group control
alternate exercises: in one day breathing exercises, active or with a load of large muscle groups (according to tolerance) with a maximum limit of 2 kg, sedation out of bed, walking. On another day aerobic exercise with cycle ergometer limited to 30 minutes.
Experimental: intervention group
He received the same intervention as the control group, associating respiratory muscle training 1 time a day with power breathe 3 series of 10 repetitions (started with 30% of the Pimax value) with readjusted load every 7 days.
Device: power breathe
respiratory muscle training 1 time a day with power breathe 3 sets of 10 repetitions

Primary Outcome Measures :
  1. impact on functionality [ Time Frame: 14 days ]
    respiratory muscle training appears to impact functionality
