Fascial Tissue Response to Manual Therapy: Implications in Long COVID-19

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.

• Guidebook (Other): Folder that will be given to the participant to carry out 5 minutes of intervention daily
• Guidebook and Myofascial Reorganization® (RMF). (Other): The intervention will be carried out once a week for 30 minutes for 6 weeks. It will include passive, active-assisted moments (with and without load). In addition to a folder that will be given to the participant to carry out 5 minutes of intervention daily.

Primary outcomes

• Functioning and disability [6 weeks]: Will be assessed using the "World Health Organization Disability Assessment" questionnaire (WHO-DAS 2.0), translated and validated for the Brazilian population by Silveira et al. (2013).
• Biomechanical and tissue viscoelastic properties [6 weeks]: Will be evaluated by MyotonPro (MytonPro, Myoton Ltd.s., Tartu, Estonia)

Secondary outcomes

• Work capacity [6 weeks]: Will be assessed by the "Work Limitations Questionnaire, WLQ-25" translated and validated for the Brazilian population by Soárez et al (2007).
• Level of Quality of life [6 weeks]: Will be assessed by the "World Health Organization Questionnaire" in its short version, validated in the Brazilian population and by the "Medical Outcomes Study 36-Item Short Form Health" questionnaire Survey" validated for Brazilian-Portuguese.
• Upper limb dysfunctions [6 weeks]: Will be assessed using the Arm, Shoulder and Hand Dysfunctions questionnaire (DASH), translated and validated for the Brazilian population by Orfale et al (2005).
• Balance [6 weeks]: Will be assessed using the Neurocom Balance Platform (VRS Sport) and its NeuroCom®Balance Manager program (Neurocom International, Inc, Clackamas, OR).
