Benefits of inspiratory muscle training under indirect home supervision in patients with human T-cell lymphotropic virus type 1

Abstract

Introduction: The presence of human T-cell lymphotropic virus type 1 (HTLV-1) associated with neuropathy (myelopathy/tropical spastic paraparesis - HAM/TSP), can generate morphological and functional changes in the respiratory system. As a preventive therapeutic possibility for respiratory dysfunctions, it is expected that the already conceptualized inspiratory muscle training, when performed at home, can be a therapeutic resource that favors adherence to treatment. Objective: To evaluate respiratory muscle strength in patients with HTLV-1 after participating in a home respiratory muscle training protocol under indirect supervision. Method: This was a clinical, longitudinal, prospective, quantitative, and single-center trial approved by the Research Ethics Committee of the State University of Pará, opinion no. 2.695.505 and registered in clinical trials NCT03829709. Six HTLV-1 patients participated in a 5-week home respiratory muscle training protocol lasting 30 minutes daily through a linear load inspiratory muscle trainer. For the characterization of the imposed load, they were submitted to manovacuometry during pre (T0), peri (T3), and post (T5) treatment. Results: Six individuals completed the program, of which 83.33% were female and 16.66% male. With the application of respiratory muscle training, it was possible to achieve a significant increase (p < 0.011) of the maximum inspiratory pressure as shown when comparing T0 (66.8±12.58) to T5 (115.08±31.78). Conclusion: This study identified an increase in inspiratory muscle strength after HTLV-1 patients participated in a home muscle training protocol under indirect supervision.

“…As for the physical therapy resources used in the treatment, the use of individual outpatient kinesiotherapy was identified through functional exercises 36,37,38,39, home exercises 40 , proprioceptive neuromuscular facilitation 41,42 , Pilates 43,44 , virtual reality 45,46 , respiratory training 47 , electrical stimulation 48,39 , neuromodulation with tDCS 49 and rTMS 29 . Most of these resources have no side effects, are low cost, help to delay the evolution of dysfunctions and have a positive impact on quality of life.…”
