The effect of myofascial release in patients with breast cancer-related lymphedema: a cross-over randomized controlled trial

AIM: This study aimed to compare the effects of myofascial release (MFR) on upper extremity volume in patients with breast cancer-related lymphedema (BCRL). DESIGN: A randomized, single-blinded, cross-over, controlled trial.SETTING: An outpatient rehabilitation clinical setting. POPULATION: Thirty patients with BCRL.METHODS: Within a crossover design with randomized treatment sequences, fifteen subjects received MFR for 4 weeks, followed by 4 weeks of washout period, and then received placebo MFR and the other fifteen subjects received interventions in the reverse order. Each session had a 60 min process including either MFR or placebo MFR for 30 min, followed by complete decongestive therapy for 30 min twice a week. Upper limb volume as the primary outcome and subjective pain, shoulder range of motion (ROM), chest mobility, shoulder function, and quality of life as secondary outcomes were assessed before and at the end of each intervention period. RESULTS: There were significant differences in upper limb volume after both MFR and placebo MFR (P<0.05) while no significant difference between MFR and placebo MFR treatments was found (P>0.05). MFR-based treatment also achieved a greater improvement than placebo MFR -based treatment in subjective pain and shoulder ROM (P<0.05), except for internal rotation, and shoulder function.CONCLUSIONS: MFR-based treatment showed clinical improvement in shoulder function, induced by decreased edema volume and pain, and improved ROM and chest mobility. However, a further study with parallel randomized controlled trials to confirm what was achieved in the present study. CLINICAL REHABILITATION IMPACT: MFR-based treatment is considered an important part of BCRL rehabilitation. Moreover, MFR -based treatment may be safe for patients with BCRL.

Automated summary

This study aimed to compare the effects of myofascial release (MFR) on upper extremity volume in patients with breast cancer-related lymphedema (BCRL). The results showed that MFR treatment can significantly reduce upper limb volume, improve pain and shoulder range of motion, and improve chest mobility. This indicates that MFR treatment plays an important role in BCRL rehabilitation.
