Detaillierte Beschreibung

This research project will be prospective, analytical and of the randomized controlled clinical trial type, with blind evaluator. The sample type will be consecutive from Santa Casa de Misericórdia de São Paulo. We will study 30 adults of both sexes with moderate to severe asthma between the ages of 20 and 70, based on the sample calculation of the outcomes of this study.

Adult individuals 20 years of age or older with a diagnosis of moderate to severe asthma of both sexes, attended at the Ambulatory of Difficult Asthma Control of Santa Casa de Misericórdia de São Paulo.

Exclusion terms include subjects diagnosed as having heart disease associated with pulmonary disease, musculoskeletal pathology that may interfere with assessment or exercise, pulmonary hypertension, calcium absorption deficiency, BMI ≥ 30 or difficulty learning.

The subjects will initially be pre-evaluated by performing pulmonary function tests, peripheral muscle strength (1-RM), functional capacity tests, physical activity questionnaires and clinical control of asthma and cardiopulmonary exercise test. After the evaluation, patients will be randomized into two resistance training groups, one of them associated with active LED phototherapy and another LED phototherapy placebo.

The resistance exercise protocol will be performed on the muscles: Pectoral, Large Dorsal, Brachial Biceps, Brachial Triceps, Quadriceps and Tibial Ischia. The intensity will be from 40 to 70% obtained in the 1-RM test with two to three sets of ten repetitions.

The load increase will be performed weekly (5%) according to patient tolerance. After 12 weeks all subjects were reevaluated and the last reevaluation occurred at the end of the training program. Patients will only effectively begin participating in this study after explaining the terms of the survey and by accepting written consent from the ICF.

The mean (in kg) of the resistance training protocol for lower limbs in knee extension of group 1 was 33 ± 13 kg and the mean of group 2 was 46 ± 11 kg. The sample calculation was based on the load of the quadriceps muscle, α = 0.05 and β = 95%, determining a minimum of fourteen individuals for each group. An additional 10% was added to compensate for possible losses during the protocol. Thus a minimum of fifteen individuals will be required for the study.

Linear regression models will be used to evaluate the effect of the LED on the results (absolute change and percentage) and a sensitivity analysis with the values of the results in the revaluation, adjusted by the initial value of each result. The possible correlations between the variables can be evaluated using Pearson's correlation. The level of significance adopted will be p <0.5. The analyzes were performed with SPSS 20 software.

Waffen und Interventionen

Teilnehmergruppe / Arm
Intervention / Behandlung
Aktiver Komparator: photobiomodulation by active LEDT
The subjects will be initially pre-evaluated by performing pulmonary function tests, peripheral muscle strength tests, functional capacity tests, physical activity questionnaires and clinical control of asthma, and cardiopulmonary exercise test. After the evaluation, patients will be randomized into two resistance training groups, one of them being associated to the intervention with active photobiomodulation by LEDT to increase peripheral muscle function post resistance training.
Light-emitting diode, has effects similar to the photobiomodulation by low-level laser intensity.

Zeitfenster
Functional Capacity by Cardiopulmonary exercise test.
Zeitfenster: Change from baseline measured by cardiopulmonary exercise test up to 24 weeks.
The cardiopulmonary test will be performed in an electricomagnetic braking cycle ergometer connected to a system composed of gas analysis module attached to a module flow/wave analyzer and a microcomputer BreezeCardiO2 System. (medical Graphics Corporation - MGC, St. Paul, Mo, USA).
Change from baseline measured by cardiopulmonary exercise test up to 24 weeks.
Functional Capacity by Incremental Shuytle Walk Test.
Zeitfenster: Change from baseline measured by Incremental Shuttle Walk Test distance up to 24 weeks.
The incremental shuttle walk test was performed based on the original test description. The patient walk from side to side in a space of 10 meters identified by two cones inserted 0.5 from each end to avoid such sudden changes in speed. The participant was instructed to walk from cone to cone in one. A single point that the participant must keep pace and a triple beep indicates the beginning of a new level, the height at which the participant has increased the pace. The test comprised 12 levels, each lasting one minute. The speed of the first level was 1.8 Km/h, with an increase of 0.17 m/s every minute until reaching a top speed of 8.53 Km/h. The test was stopped when the participant was unable to reach the cone before the next beep.
Change from baseline measured by Incremental Shuttle Walk Test distance up to 24 weeks.
