We would like to thank the reviewers for their comments regarding the possibility of the noninclusion of patients with psychiatric and neurological comorbidities in our study. This would have been very interesting, but it would be almost impossible to conduct such an investigation. Regarding the noninclusion of patients with neurological conditions, this would not apply to a sample with associated myelopathy (HAM/TSP), as this is a neurological condition per se. The noninclusion of patients with comorbid psychiatric symptoms would have helped answer the question of the efficacy of an exercise protocol in the control of pain, but around 70% of our symptomatic patients with HAM/TSP present depression traits as comorbidity¹. Hence, their exclusion would substantially decrease the sample size and prevent the study from being developed. Furthermore, and probably based on the same difficulties, many studies investigating disability²^,³^,⁴, and exercises⁵^,⁶^,⁷ in HTLV-1 patients with or without HAM/TSP did not use the presence of psychiatric disorders as noninclusion criteria. Based on these facts, the proposed procedure for non-including patients with psychiatric disorders in HTLV-1 studies of pain seems to be unfeasible. Even controlling the results for the presence of these symptoms tends to be difficult, as this analytic approach would fall into low statistical power due to unbalanced groups.
