Objective: Investigate the effects of multisensory training with and without the anchor system on breast cancer survivors' postural balance and self-efficacy of falls., Design: Clinical randomized, controlled, and crossover trial., Setting: Teaching, Research, and Assistance Center in Mastectomized Rehabilitation., Participants: Eighty breast cancer survivors homogeneously distributed in the groups of adults and elderly affected, or not, by lymphedema., Interventions: Participants were randomized to multisensory training with and without the anchor system involving 3 sessions per week for 12 weeks. After the 4-week washout period, the remaining therapeutic intervention was applied., Main Outcome Measures: The primary outcome was semi-static and dynamic balance as evaluated by baropodometry and Mini Balance Evaluation Systems Test, and the secondary outcome was self-efficacy of the fall episode as assessed by Falls Efficacy Scale - International in the pre-, post-immediate, and 4-week follow-up period., Results: Both therapeutic interventions caused positive and significant effects on postural balance and self-efficacy of falls in the immediate period. The multisensory training with the anchor system induced significant functional retention in the short term, related to the clinical effect of small to moderate variation., Conclusions: Multisensory training with the anchor system is convenient for postural balance and self-efficacy for falls, regardless of age and upper limb volume, for breast cancer survivors., (Copyright © 2023 American Congress of Rehabilitation Medicine.

Introduction: Breast cancer affects women of different ages, and comorbidities resulting from treatment can affect postural stability. The study aimed to evaluate the influence of age and lymphedema on the postural balance of women undergoing breast cancer treatment., Methods: The study included 77 women undergoing breast cancer treatment, divided into different groups: 37 young adult women divided into 17 with lymphedema (GYL) and 20 young adults without lymphedema (GY); 40 elderly women, 20 elderly women with lymphedema (GEL) and 20 elderly women without lymphedema (GE). Mini Balance Evaluation Systems Test (Mini BESTest) and Falls Efficacy Scale - International (FES-I) were used., Results: Mini BESTest and FES-I between the groups showed that GE and GEL had a significant difference to GY. Mini BESTest Total and Time Up and Go TUG-Double Task showed that GE has a significant difference to GYL, with GE and GEL having lower scores. Moderate negative correlation in the GEL between FES-I and Mini BESTest. In the age correlation between the Mini BESTest, FES-I, TUG, and double task TUG, a moderate positive correlation was observed for TUG. GEL showed a moderate positive correlation for FES-I and double-task TUG, strong for TUG, and moderate negative correlation with Mini BESTest. Correlation of the volume difference between the limb affected and not affected by lymphedema and the FES-I, Mini BESTest, TUG, and TUG double task, GYL showed moderate negative correlation for TUG., Conclusion: Age and lymphedema influenced the dynamic postural balance of women undergoing breast cancer treatment., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to declare., (Copyright © 2021 Elsevier Ltd.
