The effect of proprioceptive neuromuscular facilitation techniques compared to general aerobic exercise on balance, fear of falling, and quality of life in older adults living in nursing homes: a randomized controlled trial.

Abstract

Background: With aging, changes occur in various body systems, such as cardiovascular, respiratory, neuromusculoskeletal, and vestibular, leading to a decreased quality of life (QOL) and an increased fear of falling (FOF). Exercise and physical activity reduce the progression of aging complications. Therefore, we examined the effect of proprioceptive neuromuscular facilitation techniques compared to aerobic exercise on balance, fear of falling, and quality of life in older adults living in nursing homes.

Methods: Fifty-two older adults aged over 60 (31 males, 21 females) living in nursing homes were included. After initial evaluation, individuals were randomly assigned to two treatment groups (PNF techniques and aerobic exercise). Both treatment groups received 12 treatment sessions over 4 weeks. Balance, fear of falling, and quality of life were assessed at baseline and after a 4-week intervention. Analysis of covariance (ANCOVA) and paired samples t-test were utilized to between and within-group changes of variables.

Results: The results showed no significant differences in balance, fear of falling, and quality of life between groups after the intervention (P > 0.05). In the within-group comparison, only the PNF techniques group showed significant improvement in the Berg Balance Scale (BBS) after the intervention (P < 0.05).

Conclusion: The findings suggest that PNF techniques compared with aerobic exercise could not contribute to improved balance, fear of falling, and quality of life. Therefore, more clinical trial studies with a control group are needed to determine the exact effects of these techniques.
