Brief Summary

The main objective of the research will be to analyze, through surface electromyography, the impact of inspiratory muscle training before a supervised home training protocol in patients with human T-cell lymphotropic virus type 1 (HTLV-1). For this, a clinical, longitudinal, prospective, quantitative and single center trial will be carried out, aiming at home inspiratory muscle training lasting 5 weeks, 3 times a week, 30 minutes daily through the IMT Threshold, with 14 volunteers enrolled in the Laboratory of Studies in Functional Rehabilitation (LAERF) of the Federal University of Pará (UFPA). They will be classified as the manifestation of Tropical Spastic Paraparesis / Myelopathy (PET / MAH) for GP (PET / MAH probable) and GD (PET / MAH definitive) groups, obeying inclusion criteria. For characterization of expiratory flow rates and flows, as well as respiratory muscle strength, they will be submitted to spirometry and manovacuometry, pre, per, and post treatment, respectively. For the analysis of the electromyographic activity, the diaphragm, parasternal and sternocleidomastoid muscles will be counted in the follow-up during the analysis of inspiratory muscle strength, as well as once a week during the conduction of the inspiratory muscle training protocol. The collected data will be stored in a Microsoft Office Excel® 2010 worksheet and then submitted to statistical analysis using the Bioestat 5.0® program, adopting a standard error of 5%. The theoretical support of the research will have a bibliographical survey of scientific articles collected during the design of the project, and the accomplishment of the research. It is expected to map, through the surface electromyographic study, the impact of respiratory muscle training at a distance on the inspiratory muscle strength of patients with HTLV-I virus with probable or definitive PET / MAH.

Outcome Measures

Primary Outcomes (1)

  • Inspiratory and expiratory muscle force

    The evaluation of respiratory muscle strength will be performed by measuring the maximal inspiratory pressure (PiMáx) and expiratory (PeMAx) measurements with manovacuometer (+ - 300cmH2O). In order to perform the measurement of PiMáx and PeMáx, referring to inspiratory and expiratory muscle strength respectively. The values can range from 0 to 300 cmH2O, being 0 no strength and 300 maximum respiratory muscle strength.

Study Arms (1)

Intervention Group

EXPERIMENTAL

The inspiratory muscle training (IMT) will be performed in the morning shift for 30 minutes, 3 times a week for 5 weeks. The first training session each week will be held at the LAERF under the direct supervision of the investigator and the other two home-based training sessions under the supervisor's distance supervision. They will receive the Threshold® IMT linear loading device, and guidelines for handling, posture and asepsis. The initial training load for each participant will be adjusted to 25% of PiMáx. Participants will be trained and instructed to do the exercise program on their own at home. Once a week, during the return to the laboratory the researcher will determine the new values for load (1st week 25%, 2nd week 35%, 3rd week 40%, 4th week 45%, 5th week 50%).
