Rehabilitation of Patients With Lung Chronic Obstructive Pulmonary Disease

Overview

Chronic obstructive pulmonary disease (COPD) is characterized by the obstruction is not fully reversible airway, where the severity of the disease and the prognosis is not determined solely by changes in lung function. Pulmonary rehabilitation is a multidisciplinary program of care for patients with chronic respiratory diseases, individually designed to optimize physical and social performance and autonomy of these patients, promoting improvement in functional exercise capacity, quality of life, reducing dyspnea, frequency and duration of hospitalizations and reduce the frequency of exacerbations of the disease. The overall objective of the research is to evaluate the effects of pulmonary rehabilitation program on exercise capacity, lung function, quality of daily life and reduction of dyspnea in patients with COPD. A study type randomized, open-label trial following the recommendations of the CONSORT (Consolidated Standards of Reporting Trials) will be held. The study will be conducted at the Clinic Physiotherapy Course of the School with a sample of 58 patients. The intervention will be performed sessions three times a week for 16 weeks (8 weeks for assessment and 8 weeks for adaptation and (pulmonary rehabilitation training). The PR (pulmonary rehabilitation) will last 60-120 minutes each.O group A (control) will receive treatment of traditional pulmonary rehabilitation and without resistive training for upper limb (UL) and group B will receive the same treatment control with additional training of upper limb strength.

Detailed Description

Chronic obstructive pulmonary disease (COPD) is characterized by the obstruction is not fully reversible airway, where the severity of the disease and the prognosis is not determined solely by changes in lung function. Pulmonary rehabilitation is a multidisciplinary program of care for patients with chronic respiratory diseases, individually designed to optimize physical and social performance and autonomy of these patients, promoting improvement in functional exercise capacity, quality of life, reducing dyspnea, frequency and duration of hospitalizations and reduce the frequency of exacerbations of the disease. It is still reported in the survey improved ability to perform activities of daily life, exercise capacity, quality of life, reduction in respiratory symptoms, anxiety and depression in patients with chronic lung diseases. The overall objective of the research is to evaluate the effects of pulmonary rehabilitation program on exercise capacity, lung function, quality of daily life and reduction of dyspnea in patients with COPD. A study type randomized, open-label trial following the recommendations of the CONSORT (Consolidated Standards of Reporting Trials) will be held. The study will be conducted at the Clinical Department of Physical Therapy School The calculation of the sample held at LEE program (epidemiology laboratory and statistics) with 95% confidence interval and allowing a loss of 20% the sample then goes to 58 patients. Inclusion criteria: Patients with COPD eligible to moderate COPD according to the criteria of gold GOLD (Global Initiative for Chronic Obstructive Lung Disease) as well as being ex-smokers and no exacerbation of the disease in the last three months. Accompanied by a pulmonologist. Age between 40-85 years. Be not practicing physical activity and without cardiovascular or orthopedic disease, make use of bronchodilators and oral theophylline, oxygen therapy or corticosteroids. Exclusion criteria: Patients who have comorbidities musculoskeletal, peripheral saturation of oxygen fall lower than 90% during the 6 minute walk test (six) minutes. Difficulty cognitive understanding of body awareness. The evaluation procedure will be: functional independence measure (FIM); london chest activity of daily living (LCADL); scale medical research council (MRC); the world health organization disability assessment schedule 2.0 (WHODAS 2.0); anthropometric examination; walk test of six (6) minutes; step test; As the repetition maximum (RM); muscle activation – electromyography; grip strength of the upper limbs (DMS); ultrasound diaphragm dynamometer; spirometry; respiratory muscle strength; saint george in respiratory disease questionnaire (SGRQ). The intervention will be performed sessions three times a week for 16 weeks (8 weeks for assessment and 8 weeks for adaptation and PR training). PR will last from 60 to 120 minutes each. Patients who agree to participate and the PR will be divided into two groups randomly through enveloped draw. Group A (control) will receive treatment from traditional pulmonary rehabilitation and without resistive training for upper limb (UL) and group B will receive the same treatment control with additional upper limb resistance training. For data analysis continuous variables will be analyzed with central tendency and dispersion measures, data or dichotomous categorical variables will be analyzed frequently measures. For the realization of inferential statistics are. Since the data are normally distributed, the Student t test for independent samples. The Mann-Whitney test is used to compare the differences in the means of the variables between the groups. To analyze the correlation between the functional capacity variables and QOL will be used in calculating the Pearson correlation coefficient (r) if the data are normally distributed and the calculation of the Spearman correlation coefficient was not distributed normally. To evaluate the reliability will be used the coefficient of intra-class correlation coefficient (ICC). Statistical analysis will be performed using the Statistical Package for Social Sciences for Windows (version 17.0).

Interventions

  • Other: upper limb exercises
    • HEATING PHASE: diagonals for upper and lower limbs (5-10 minutes). AEROBIC PHASE: aerobic exercise on a treadmill or bicycle between 5 – 30 minutes and rest 1-2 minutes according to the Borg scale and patient tolerance (Borg scores for dyspnea 4-5); RESISTANCE STAGE: upper limb exercises with weight training equipment or dumbbells (the patient’s adaptation) with 50% of maximum load reached the maximum repetition test. Series 2 minutes and rest interval between sets 1-2 minutes. RESPIRATORY TRAINING : Strengthening of the respiratory muscles 5-15 minutes with Threshold with load of 50% of the affected MIP (measure maximal inspiratory pressure) evaluation. RELAXATION: Stretching and muscle massage therapy group involved in the 5-10 minute workout.
  • Other: without training for upper limb
    • HEATING PHASE: diagonals for upper and lower limbs (5-10 minutes). AEROBIC PHASE: aerobic exercise on a treadmill or bicycle between 5 – 30 minutes and rest 1-2 minutes according to the Borg scale and patient tolerance (Borg scores for dyspnea 4-5); RESPIRATORY TRAINING: Strengthening respiratory muscles 5-15 minutes with Threshold with load of 50% of MIP hit in the evaluation. RELAXATION: Stretching and muscle massage therapy group involved in the 5-10 minute workout.
