Inspiratory Muscle Training and Respiratory Electromyographic Activity in COPD
Condition: Chronic Obstructive Pulmonary Disease
MeSH terms: Lung Diseases; Lung Diseases, Obstructive; Pulmonary Disease, Chronic Obstructive
Study type: Interventional

Summary: 
      Intended to treat disorders of the respiratory muscles can use the device Threshold IMT ®
      through an inspiratory muscle training (IMT) that allows training of the inspiratory muscles,
      the chief of these being the diaphragm which is which objectified the improvement of its
      function . To monitor the action of the respiratory muscles can be used several tools such as
      manometer that aims to assess respiratory pressures, ie, the strength of respiratory muscles,
      or the Surface Electromyography (sEMG) that allow evaluating the electromyographic activity
      of muscles analyzed. From a quantitative clinical trial, randomized and blinded, composed of
      45 individuals obtained by random convenience and divided into three groups, COPD
      participating in a pulmonary rehabilitation program (RP) which will make TMI (TGR - Trained
      Group Rehabilitated), COPD does not participant in a PR program (TGNR - Trained Group not
      Rehabilitated) and a control group composed of healthy individuals (CG) that seek to analyze
      the electromyographic activity of sternocleidomastoid (SCM) and diaphragm muscle strength,
      lung volumes and breathing patterns before and after a period of eight weeks of TMI. Manual
      will also be held dynamometry to compare the grip strength of the CG, TGR and TGNR only at
      baseline.

      Hypothesis:

        1. The Inspiratory Muscle Training (IMT) increases the maximal inspiratory pressure (MIP)
           in COPD patients regardless of whether they are enrolled in a program of pulmonary
           rehabilitation (PR).

        2. TMI alters the breathing pattern in COPD patients regardless of whether they were
           entered into a PR program.

        3. Patients with COPD who do not participate in a PR program have higher handgrip strength
           compared to patients who did not participate in a PR program.

        4. There is decreased activity of the sternocleidomastoid muscle due to increased activity
           in the diaphragmatic muscle fibers after a period of TMI.

        5. TMI in COPD patients participating in a program RP produces greater increase in MIP, the
           handgrip strength, improves breathing pattern and a greater reduction in the activity of
           the SCM muscle and diaphragm than in those who did not participate in a program RP.

        6. There will be a reduction in respiratory rate, heart rate, systolic and diastolic blood
           pressure and increased oxygen saturation at the end of the TMI.

        7. TMI reduce the degree of dyspnea reported by patients as MRC scale at the end of the
           training period.
    


Intervention name(s): Inspiratory Muscle Training; Pulmonary Rehabilitation
Intervention type(s): Other; Other
Intervention description(s): Will be held inspiratory muscle training associated with a pulmonary rehabilitation program. The inspiratory muscle training is performed with a load of 40 to 50% of the muscle strength of the subjects.; Pulmonary Rehabilitation consists of isotonic exercises of upper and lower limbs, 20-minute workout on cycle ergometer in standard deflation (expiration at the time of muscle contraction), is performed three times a week for eight weeks.
