Volume 20, Issue 23 (9-2022)
Abstract
Considering the prevalence of pain and disability in the knee joint, the present study investigated the effect of core stability training with improving knee joint proprioception on balance, pain and functional disability of women with chronic knee pain. 20 women aged 30 to 50 with chronic knee pain were placed in two experimental and control groups. To measure static and dynamic balance, pain and functional disability, the stork balance tests, Y, VAS and VOMACK questionnaire were used, respectively. Exercises were followed for eight weeks in the experimental group. To evaluate the research hypotheses, the analysis of variance test with repeated measurements was used in spss software version 24. The results showed that before the exercise protocol, there was no significant difference between the control and experimental groups in any of the measured variables. While the eight-week training protocol caused a significant difference in static and dynamic balance, functional disability and pain between the control and experimental groups. Therefore, core stability training with improving knee joint proprioception increase balance in people with chronic knee pain, which can reduce the risk of falling in these people and improve the quality of life by improving pain and functional disability.

Abstract
Mental fatigue is usually caused by long-term cognitive activities; in a way that reduces cognitive performance and leads to changes in functional activities. Therefore, the purpose of this study was to investigate the effect of a session of Swedish relaxation massage and meditation in controlling mental fatigue on reactive balance and Lower extremity function of amateur athletes. In this study, 16 female physical education athletes were purposefully selected as a sample based on the study entry criteria, and were subjected to mental fatigue protocol (45 minutes of cognitive activity (Stroop test)), Swedish relaxation massage (30 minutes) and meditation (30 minutes) with a time interval of 48 hours. Reactive balance was evaluated with Y test with automatic lights and, Lower extremity function was evaluated with single hop for distance, triple hop for distance, meter-6 and hop crossover-triple distance tests. Repeated analysis of variance test was used to check intra-group changes.The findings showed that there is a significant difference between the average scores of reactive balance and lower limb performance of the subjects when comparing the post-test of mental fatigue with the post-test of massage and meditation (P<0.05). Also, there is a significant difference between the subjects' scores comparing massage and meditation for reactive balance and body function (P<0.05).In order to prevent sports injuries in athletes, Swedish relaxation massage and meditation can be used as an intervention to speed up the recovery of mental fatigue and improve reactive balance and body function.

Abstract
The purpose of this study was to investigate the effect of eight weeks of core stability exercises on upper limb performance based on Y balance test, strength and range of motion of shoulder rotation in badminton athletes. 30 male badminton players were randomly assigned to two control (n=15) and experimental (n=15) groups. The experimental group performed the core stability training program for eight weeks, three sessions a week for 40 minutes, while the control group did not receive any intervention. Measurement of upper limb function was done by Y balance test, and also shoulder strength and internal and external rotation range of motion were measured by handheld dynamometer and goniometer respectively, before and after the intervention. The analysis of the data obtained from the research based on the ANCOVA statistical test showed that there is a significant difference in the average of the Y upper limb balance test between the two control and experimental groups in both dominant and non-dominant hands. which indicates the positive effect of core stability exercises on people's performance in performing the Y balance test (p<0.05); however, no statistical difference was observed in muscle strength and range of motion of external and internal rotation of the shoulder after the intervention. (p < 0.05). It seems that the provision of core stability training programs can be considered with the approach of increasing the performance of the upper limbs and, of course, preventing injuries in badminton players.

The Effect Of Time Of Day On Postural Control Of The Elderly With Open And Closed Eyes: With A Cognitive Dual-Task Approach

Abstract
Circadian rhythms play a crucial role in regulating various physiological functions of the human body and can impact the ability tasks. The aim of this study was to investigate the effect of time of day on static and dynamic balance using the cognitive task approach. We recruited 24 elderly men who performed both static and dynamic balance tests with and without cognitive dual tasks. Our statistical analysis, using a significance level of 0.05, revealed significant differences in the parameters of the 95% confidence ellipse, length of path, and average velocity of the center of pressure when performing the dual task compared to normal walking. However, these variables did not significantly differ at different times of the day. Interestingly, our results showed that the center of pressure fluctuations in closed eyes and different times of the day did not have a significant difference. Overall, our findings suggest that healthy elderly individuals are at similar risk of falling during different hours of the day. Nonetheless, the simultaneous execution of dual cognitive tasks leads to balance disruption in both eyes-arm closed positions.

The Role Of Sensory Manipulation In Postural Control Responses: A Developmental Study

Abstract
This study aimed to determine the underlying mechanisms of age-related differences in postural control of 7-18 years old girls by determining the differences between different age groups and adults in their sensory preferences for compensatory responses. 118 non-athlete girls aged 7 to 18 were selected by available sampling and divided into four age groups: 7-9 (n=31), 10-12 (n=32), 13-15 (n=28), and 16-18 (n=27). A reference group of adults (n=28, Mean= 27.9 years) was examined for comparison. Sensory organization test (SOT) with computerized dynamic posturography was used to manipulate sensory inputs. One-way analysis of variance and Tukey post hoc test showed a significant difference between all age groups in 6 test conditions (P<0.05). The use of somatosensory and vestibular sensory inputs to maintain balance was almost the same in different age groups, but significant differences were observed in the use of visual inputs. From the age of 13, the postural control performance of girls becomes similar to that of adults, which can be due to the delayed development of the visual system. In general, it seems that for perfect postural control, first the somatosensory sensory system and then the vestibular and visual systems mature.
