Effect of A Six-week Dynamic Neuromuscular Stability Training on Performance Factors and Quality of Life in the Elderly

The present study aimed to investigate the effects of 6 weeks of Dynamic Neuromuscular Stability (DNS) training on performance (lower limb strength, flexibility, fall risk) and quality of life in the elderly. This was a quasi-experimental study with a pretest-posttest design. This research was performed on 30 elderly males, aged 60-70 years in Qom Province, Iran in 2021. The examined elderly were randomly divided into the experimental and control groups (n=15/group). Furthermore, the experimental group participated in three 45-minute weekly sessions of DNS training for 6 weeks. To collect the necessary information before and after applying the training protocol, tint tests, 30-second seat sitting test, sitting and delivery test, TUG test, and SF-36 questionnaire were used. The obtained data were analyzed using Analysis of Covariance (ANCOVA) and Paired Samples t-test at a significance level of 0.05. The ANCOVA results indicated a significant difference between the experimental and control groups in motor function, fall risk, quality of life, lower limb strength, and flexibility (P<0.05). The collected mean scores outlined that the experimental group performed better than the control group. Due to the effectiveness of DNS training on physical function and the very high importance of the elderly lifestyle, it is recommended that the provided training protocol be used for prevention and rehabilitation, increase the level of physical fitness and quality of life as a low-cost treatment, among the elderly.
