Balance Changes Following a Controlled Whole-Body Vibration Training: A Pilot Analysis Addressing Balance Control in Adult Women with Obesity

Abstract

Background: The prevalence of obesity among older individuals has significantly increased in recent years, potentially doubling the risk of postural imbalance and falls. Controlled whole-body vibration (CWBV) training is considered an alternative/complementary therapy for fall prevention, but its mechanisms still require further investigation. Objectives: This study aimed to investigate the effects of CWBV on balance and fall risk among older adult women with obesity. Methods: Fifteen adult women over the age of 60 (mean age 68.55 ± 4.86, BMI: 30.57 ± 2.97) participated in this quasi-experimental study. They underwent CWBV training three times weekly for six weeks. Gait stability and balance were assessed using a gait analysis system before and after the intervention. Results: The results indicated a significant decrease in both static and dynamic balance parameters, except for the variability of velocity index (P = 0.9) and fear of falling (FES-I score, P = 0.56), after the intervention. Conclusions: CWBV training appears to be an effective method for improving static and dynamic balance parameters in older adult women. However, further research is necessary to explore different dosages and protocols of vibration training, incorporating more challenging/specialized proprioceptive exercises to potentially improve the fear of falling in this population.
