Read More Background: A common issue experienced by the elderly, often due to specific diseases or the natural aging process, is a decline in balance and posture control. This study aimed to investigate the impact of an eight-week sensorimotor training program on the balance and proprioception of older women. Methods: This study was a randomized controlled clinical trial conducted with the participation of older women aged 60-75 who frequented gyms in Urmia. From this population, thirty older women were randomly selected, meeting specific inclusion criteria, and were purposively divided into two groups: the experimental group (with an average age of 70.06±2.64 years, height of 156.13±6.14 cm, and weight of 73.11±7.81 kg) and the control group (with an average age of 67.93±2.12 years, height of 154.15±7.22 cm, and weight of 70.83±5.22 kg). The experimental group underwent an 8-week sensorimotor training program, consisting of three sessions per week, while the control group did not receive any training. Knee proprioception was assessed before and after the training by capturing photographs at a flexion angle of 40-60 degrees while standing. Additionally, static and dynamic balance was evaluated using the Sharpened Romberg Test and Time of Up and Go Test, respectively. The collected data were analyzed using ANCOVA, and the significance level was set at P≤0.05. Results: After the training intervention, the experimental group exhibited a noteworthy decrease in the absolute error of angle reconstruction (P=0.001). Moreover, there was a substantial enhancement in both static balance, with eyes open and closed (P=0.001), and dynamic balance (P=0.001) compared to the control group. Conclusion: the results of this study suggest that sensorimotor training can effectively enhance proprioception and improve balance in elderly individuals. This improvement is attributed to the positive impact of sensorimotor training, particularly in closed-chain movements, which strengthens the proprioceptive feedback from the muscles of the lower limbs. Consequently, this contributes to better balance and proprioception in older adults.

Read More Background: Forward head posture (FHP) and kyphosis are the most common postural deviations which various factors are involved in the occurrence of these abnormalities. This study aimed to compare the effect of functional corrective exercises (FCE) and core stability exercises (CSE) on forward head posture and kyphosis in adolescent girls. Methods: The present study is quasi-experiment research and included a pre- and post-test design. 52 students aged 14-16 years old with forward head posture >46 degrees and kyphosis >40 degrees were randomly assigned into four groups, each one consisting of 13 students. Research tools for kyphosis as well as forward head posture assessment included flexible ruler and goniometer, respectively. The experimental groups participated in training programs for 6 weeks, three times per week and for 60-minutes per session, while the control group continued their daily routine activities. The data analysis was carried out using covariance (ANCOVA) analysis via SPSS, version 21. Results: The outcomes showed that there were significant differences among groups, including core stability exercises (CSE) and combined exercises (FCE+CSE) (p= 0.020), core stability exercises (CSE) and Control (p= 0.008), functional corrective exercises (FCE)and Control (p= 0.001), combined exercises (FCE+CSE) and Control (p= 0.001) with respect to kyphosis. For the Forward head posture (FHP) variable, there were significant differences between pre- and post-tests of core stability exercises (CSE) and Control (p= 0.001), functional corrective exercises (FCE)and combined exercises (FCE+CSE) (p= 0.019), functional corrective exercises (FCE)and Control (p= 0.001) as well as combined exercises (FCE+CSE) and Control (p= 0.001) groups. There was no significant difference between pre- and post-test measures of control group. Conclusion: According to this study's results, although all types of training programs had a significant effect on postural correction, but a combined exercises (FCE+CSE) significantly improved forward head posture and kyphosis combined to each training program. Therefore, it is recommended that healthcare professionals and corrective exercise specialists to implement a combined program to have a better result in terms of kyphosis and forward head posture correction
