Objectives: This study aimed to assess the immediate and short-term effects of the Balance Exercise Circuit (BEC) on muscle strength, postural balance, and quality of life, with the aim of preventing falls in older adults. Methods: Twenty-two volunteers participated in this randomized controlled crossover study. Group A performed BEC training in the initial 3 months and received no intervention in the following 3 months. Group B received no intervention during the first 3 months and then participated in BEC training for the next 3 months. In addition, participants were followed for an additional 3 months. Muscle strength, postural balance, functional mobility, and quality of life were assessed, respectively, using an isokinetic dynamometer, force platform, TUG test, and the WHOQOL. Results: After 3 months of training, Group A presented improved balance and rate of force development (RFD), while Group B presented improvements in RFD, TUG performance, and WHOQOL physical and psychological domains. Regarding the short-term effects, the participants maintained the training effects in WHOQOL balance, RFD, and the social domain. In addition, the number of falls decreased during follow-up. Conclusion: The BEC intervention improved muscle strength, postural balance, and quality of life in older adults, in addition to reducing the risk of falls. Trial registration: Brazilian Registry of Clinical Trials (ReBEC) - RBR-5nvrwm.
Chronic musculoskeletal pain can be defined as persistent or recurrent pain resulting from multiple physical, mental, social and age-related factors that directly affect bones, joints, muscles and soft tissues 1 . It is one of the main causes of disabling in the elderly, leading to relevant impacts on the level of physical activity, functional mobility, mood, risk of falls and sleep quality 2,3 . Much has been discussed about the importance of promoting an approach in pain management with its patients. Pain neuroscience education contributes to greater understanding, facilitating the process in which the patient deals with his/her pain, since each person has an individual experience about pain 4,5 .Recently, multimodal circuit exercises have been recommended for older adults to increase physical-function and to prevent the risk of falls 6 . Multimodal exercises combine neuromotor skills and physical skills in the same physical training 7-11 .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
