Effects of myofascial reorganization associated with kinesiotherapy on chronic pain and functionality of breast cancer survivors: development of a study protocol for a randomized controlled trial

Abstract

Introduction: Breast cancer is the most common type of cancer among women. Treatments can lead to complications modifying upper limbs movement patterns and generating pain and functionality loss. Kinesiotherapy and myofascial reorganization (MR) have shown positive effects reducing chronic pain and improving upper limbs function. We hypothesize that these techniques can maximize results and reduce treatment time in clinical practice. Objective: To develop a study protocol to verify whether MR associated with kinesiotherapy is more effective than isolated kinesiotherapy to treat chronic pain and upper limb dysfunction in breast cancer survivors. Methods: Participants will be divided into two groups: intervention group (myofascial reorganization + kinesiotherapy) and sham group (traditional massage + kinesiotherapy). Six treatment sessions (once a week) and three-time assessment will occur. Instruments for assessing pain and functionality will be Visual Analogue Scale, Body Pain Diagram, Disabilities of the Arm, Shoulder and Hand Questionnaire, and goniometry. Statistical analysis will be conducted based on intention-to-treat analysis. To analyze the difference of means between groups, we will use T-Student or U Mann-Whitney test. Repeated measures ANOVA will be used to check treatments effects. Significance level for all tests will be 5%. Conclusion: We expect that MR associated with kinesiotherapy will improve chronic pain and upper limbs functionality of breast cancer survivors.
