Evaluation of the Effectiveness of Dynamic Neuromuscular Stability Exercises on Balance and Walking Function in the Elderly

Objectives: Walking and balance control are determining factors in the independence of the elderly because they are the main components of daily physical activity. This study evaluated the effectiveness of Dynamic Neuromuscular Stability (DNS) training on balance and gait function in the elderly. Methods: This study had a pre-test/post-test design. It was a quasi-experimental study performed on 30 older men aged 60-70 years in Qom Province, Iran, in 2021. The elderly was randomly divided into experimental (n=15) and control (n=15) groups. The Experimental Group (EG) participated in three 45-min sessions of dynamic neuromuscular stability training every week for 6 weeks, and the Control Group (CG) continued their normal daily routine. Berg balance scale (dynamic balance), modified stork stand (static balance), and temporal and spatial gait parameters were used to collect information before and after applying the training protocol. The obtained data were analyzed using ANCOVA statistical method and the paired t test. Results: There were significant differences between pre-test and post-test in EG regarding the variables of dynamic balance, static balance (P=0.001), and gait function, but in the CG, no significant difference was observed for these variables (P 0.05). Also, there was a significant difference between the mean scores obtained in the balance and gait tests between the two groups (P 0.05), and EG performed better in the post-test. Discussion: DNS training due to the great variety of movement in different parts of the body and the effect on improving strength, flexibility, range of motion, and physical fitness can also improve balance and gait function in the elderly. According to the present study results, one of the best ways to reduce the costs and physical, psychological, and social problems caused by aging is to use DNS training for the elderly.
