Chronic non-specific neck pain is one of the most common musculoskeletal disorders in modern society and is considered a cause of disability in many jobs, especially in office workers.

In this study, 36 female office worker with mean±SD age of 39.20±4.29 years, mean ± SD weight of 70.60±12.37 kg and mean±SD height of 163.15±6.23 cm were randomly divided into three groups: 1. Dynamic neuromuscular stability exercises 2. Stabilization Exercises and 3. Control group. Stabilization exercises with emphasis on the effect on deep neck muscles dynamic neuromuscular stability exercises with emphasis on the effect on cervical thoracic and lumbar pelvic chain coordination were performed for six weeks (3 sessions per week). Visual Analog Scale and disability questionnaire were used to measure the pain and disability of the subjects, respectively, and to measure muscle tolerance, two methods of assessing activation score and deep neck flexor muscle performance index were used by compression biofeedback device. Finally, data analysis was performed using SPSS software (version 22)at the significance level of P=0.05.

The one-way ANOVA test results showed a significant difference between the three groups in all variables (P<0.05). The Turkey post hoc test results showed no significant difference between the pain score and disability of the dynamic neuromuscular stability exercises and stabilization exercise groups (P>0.05). On the other hand, the results showed that after six weeks of training, there was no significant difference between muscle activation score and muscle performance index in the control and stabilization exercise groups (P>0.05).

Both training protocols had a significant effect on reducing pain and disability. However, dynamic neuromuscular stability and stabilization exercises substantially increased the tolerance of deep neck flexor muscles compared with the stabilization exercises group. It can also be a better approach to treat non-specific chronic neck pain.

Mental fatigue is known as an effective factor in reducing the performance and concentration of athletes. The aim of the present study was to investigate the effect of a meditation session in controlling mental fatigue and its effects on Proprioception changes, strength and landing mechanics of amateur athletes. In the current study, 16 female athletes were randomly selected as a sample based on the inclusion criteria. At first, the subjects were influenced by the mental fatigue protocol (45 minutes of cognitive activity). Before and after mental fatigue, Proprioception with angle reconstruction error, muscle strength with manual dynamometer and landing mechanics with landing error scoring system were evaluated. Then, after 48 hours, the subjects received a meditation session, and immediately after that, mental fatigue and the second post-test of the results of the study were performed. Repeated analysis of variance test was used to check intra-group changes. The findings showed that there is a significant difference between the average active Proprioception scores, knee extension strength, and landing mechanics of the subjects in comparison of the meditation post-test compared to the mental fatigue post-test (P<0.05). The findings of the present study showed that meditation can be used as an effective intervention in controlling mental fatigue. Therefore, in order to prevent sports injuries, athletes, especially amateur athletes in whom mental fatigue is common, can use this intervention.

 Nowadays, Participating in sports activities along with mental fatigue causes musculoskeletal injuries and one of the most important factors in reducing the rate of these injuries is having proper recovery. Swedish relaxation massage and meditation are some of the interventions that can possibly affect people’s mental fatigue. Therefore, the purpose of this study was immediate effect of Swedish relaxation massage and meditation after mental fatigue on dynamic and semi-dynamic balance and Lower extremity function in collegiate female athletes.

 the current study is a pre-experimental design with pre- and post-test and intervention practices in an experimental group. 16 female athletes aged 20 to 24 years at Razi University were purposefully selected as samples that they were subjected to protocols of mental fatigue (45 minutes of cognitive activity [stroop test]), Swedish relaxation massage (30 minutes) and meditation (30 minutes) with an interval of 48 hours. We were evaluated Dynamic balance with a Y-balance device, semi-dynamic balance with a Lafayette Stability Platform, Lower extremity function with left test. Data analysis was performed using SPSS software, version 22 through paired t-test. 

 There was a significant difference between the semi-dynamic, dynamic balance and lower extremity function means in pre-test to post-test, as the means decreased after fatigue (P<0.05). Also, there was a significant difference between post-tests means of semi-dynamic, dynamic balance and lower extremity function between Swedish relaxation massage and meditation (P<0.05).

 In order to prevent injury to athletes, Swedish relaxation massage and meditation can be used as interventions to reduce mental fatigue and improve balance and Lower extremity function.

Mental fatigue usually occurs following prolonged cognitive activity. Mental fatigue is a psychological condition that occurs as a result of long-term cognitive activities. Mental fatigue can have significant effects on the daily life of healthy people. This study aimed to investigate the effect of eight weeks of relaxation massage on the mental fatigue control and balance, lower extremity function, and landing mechanic in physical education students.

This research is a quasi-experimental study, and the statistical population of this study was physical education students. From the statistical population, 30 male students with Mean±SD age= 19.5±5.5 years, weight= 69.6±6.8 kg, height= 187.75±4.5 cm, and sports history= 2.66±1.3 years. They were selected by purposeful and were randomly divided based on Research and Criteria into two groups: control group (n=15) and relaxation massage group (n=15). Before and after relaxation massage, mental exhaustion with 45 minutes of stroke activity (Stroop test), Dynamic Balance with Y test, Semi-dynamic balance with Lafayette Stability Platform, lower extremity function by the Lower Extremity Functional Test (LEFT) test and landing mechanic by LESS, Jump-landing skill film assessment by Auto CAD and Kinovea software were measured. Data analysis was performed in SPSS v. 22 software by using Statistical method of ANOVA test with repeated measures and paired t-test at the significant level P=0.05. 

The results showed that a significant difference was observed between the relaxation massage group and the control group on lower limb function, landing mechanics, dynamic balance, and semi-dynamic balance of physical education students (P=0.001).

Significant changes in lower limb function factors, landing mechanics, dynamic balance, and semi-dynamic balance in physical education students after relaxation massage exercises indicate the importance of this issue. Injury prevention specialists should study and research in introducing strategies to deal with the occurrence of mental fatigue.

Recently, the effects of modern rehabilitation equipment, especially virtual balance practice, has attracted the attention of clinical researchers. The purpose of the current study was to investigate the effect of virtual balance practice on the dynamic and static balance of athletes after knee joints reconstruction of the anterior cruciate ligament.

In the present clinical trial study, 30 patients were selected purposefully and randomly divided into two groups of control (n=15) and experimental (n=15). The experimental group performed rehabilitation practice prescribed by sports medicine specialists and virtual balance practice for 15 weeks, and the control group performed only equilibrium rehabilitation during this period. Before and after the interventions, the static balance and dynamic balance were evaluated using a Stabilometery device and Star Scursion Balance Test (SSBT), respectively. Data were analyzed using SPSS, version 22, running paired and independent sample t-test at a significance level of P=0.05.

Comparison of static and dynamic balance indices that both groups had a significant statistical difference between pre-test and post-test in static (total COP sways, mediolateral COP sways, Anterio posterior Sways) and dynamic balance tests (p < 0.05). Moreover, pre-test to post-test mean differences for static balance values had significantly decreased (p < 0.01), but it increased for the dynamic balance (p < 0.01) compared with the control group.

According to the results, virtual balance exercises can be used as a challenging exercise that involves various stresses on several laps on ligation, musculoskeletal structures around the joints, and improves the balance and reduces knee ligament injuries, especially the anterior cruciate ligament.

The purpose of this study was to investigate the The Effect of Eight Weeks Yoga Training on the Mental Fatigue Control and Balance, Lower Extremity Function and Landing Mechanic in physical education Students

In this experimental study, 36 physical education Students into experimental (15) and control (15) groups. The experimental group received 3 sessions of 1 hour sessions per week for eight weeks. Before and after yoga, mental exhaustion with 45 minutes of stroke activity (Stroop test), Dynamic Balance with Y test, Semi-dynamic balance with Lafayette Stability Platform, lower extremity function by LEFT Test and landing mechanic by Balance Error Scoring System, Jump-Landing skill film assessment by Auto CAD and Kinovea software were evaluated. Data were analyzed by SPSS software and paired sample t-test
