Disability and pain in capoeira practitioners

Dear Editor,

We were very pleased to read the article entitled “Disability and pain in capoeira practitioners” by Jorge William de Sá Campos¹ and his colleagues. In this article, the authors revealed that the knees, lower back, and wrists/hands were the regions of the body with the highest reports of pain and disability. However, some issues have been noted from our point of views.

Most studies used nonprobability sampling across a wide variety of settings, which may introduce selection bias. Therefore, one limitation of this study is that selection bias is not avoided. Where does sample come from? General demographic characteristics of participants are not explained in this study. Another limitation is a small sample size and possible sample biases.

In this study, the practice of fighting, martial art, or combat sport were excluded; thus, it is unclear that disability of the knees, lower back, and wrists/hands is also common among participants who take the practice of fighting, martial art, or combat sport. The reliability and validity of pain questionnaire was not offered in this study. In additional, details of the quality control process should be reported in the “Methods” section.
