Participants reported to have long COVID, of both sexes, aged between 20 and 80 years, from the community, outpatient clinics and hospitals will be evaluated. The treatment of participants will be carried out at the CEFID-UDESC Physiotherapy School Clinic, where they will undergo assessment of the biomechanical and viscoelastic properties of tissues, postural control, pain and quality of life. For normality analysis, the Shapiro-Wilk test will be applied, and according to the distribution of the data, parametric or non-parametric tests will be used. Pre- and post-assessment and treatment data will be compared using descriptive statistics and Student's t-test with a significance level of p=0.05 for parametric data or Wilcoxon for non-parametric data.
