Introduction Lateral ankle sprain is one of the most acute injuries that because of making damage to proprioception and causing balance decrease, result in high risk of reinjuries therefore the aim of this study was to the camparison of the effect of the three rehabilitation methods of traditional, suit therapy and combined on dynamic balance in athletics with lateral ankle sprain Material and methods: Thirty athletes suffering from grade 3 of lateral ankle sprain participated voluntairly in this study. They were divided in to three groups of rehabilitation. Athletes participated in rehabilitation training for eight week( three sessions each week for 45 minuts each session). Dynamic balance was assessed using modify star test in three directions of anterior, inside posterior and lateral posterior before and after eight weeks. Data were analysed using covariance test (P<0/05). Results The results of study showed significant difference in dynamic balance between three group(P<0/05), between combination method with suit therapy method(P<0/05) and combination method with traditional method(P<0/05), but no significant was observed between traditional method and suit therapy group(P>0/05). Conclusions It can be concluded that combination method does more effect on dynamic balance, so it can be recommended as the best method for rehabilitation of athletes who suffer from lateral ankle sprain.

Background & Aims Mental retardation is one of the most common mental disabilities and in these people there is a disturbance in balance. The purpose of this study was Comparing the effect of Core Stability Training program and Closed Kinetic Chain Training program on the dynamic balance of mentally retarded students. Materials & Methods In semi-experimental study that 45 male mentally retarded students in three groups 15 people Control, Core Stability and closed kinetic chain was set. Training group performed core stabilization trainings and closed kinetic chain trainings for 8 weeks and three times per week were studied. The pre-test and post-test of Get Up and Go test was done for measure dynamic balance of three groups. ANOVA test used to analyze the data (p≤ 0. 05). Result dynamic balance results showed significant differences in mean Core Stability and control groups (P=0. 000), closed kinetic chain and control groups (P=0. 006) and Core Stability and closed kinetic chain groups (P=0. 002). Conclusion Core stabilization training program and closed kinetic chain training program improve the static and dynamic balance of mentally retarded students and can be used for improve dynamic balance in rehabilitation of mentally retarded students.

Background and aim The Limitations of the ankle dorsi flexion range of motion causes changes in the lower limb biomechanics and stability of the ankle. So the purpose of this study was investigate the effect of 6 weeks stretching exercise of Gastrocnemius-Soleus complex on dorsiflexion range of motion, ankle proprioception, knee valgus and function in athletes with limited dorsiflexion. Material and method: in this semi-experimental study 12athletes with ankle dorsi flexion limitation were selected and divided into two groups of control and intervention (12 controls (age 23. 50± 2. 14 year, height23. 50± 2. 14 cm and weight 23. 50± 2. 14 kg) and 12 experimental (age 23. 00± 1. 72 year, height 178. 80± 5. 25 cm and weight 67. 75± 9. 16 kg) groups). The ankle dorsiflexion range of motion and proprioception were measured by universal goniometer, knee valgus by the camera, and function were measured by Single-leg hop test, Single Leg Cross Hop Test, and 8 test in pre test and after 6 weeks Gastrocnemius-Soleus stretching intervention. The analysis of covariance in SPSS program version 21 used for statistical analysis. Alpha level set at ≥ 0. 05. Results after implementation of stretching exercise, significant differences were seen in ankle dorsiflexion range of motion (P=0. 001) and function (P=0. 001), but there was no significant difference in knee valgus (P=0. 450) and ankle proprioception (P=0. 470). Conclusion Adding Gastrocnemius-Soleus stretching to rehabilitation programs for athletes with ankle motion limitation is recommended to reduce consequences such as dorsiflexion range of motion and motor function limitation.

Background and aim Fatigue is one of the most important factors affecting the occurrence of sport injuries. The purpose of this study was to determine the effect of functional fatigue on the position sense of ankle joint on female futsal players. Materials and method In this semi experimental study, 22 female futsal students of Isfahan University with the mean and standard deviation of age 20 ± 1. 8 years, weight 57 ± 2. 40 kg, and height 161. 5 ± 5. 73 cm were selected as the study samples using convenient sampling technique. Functional futsal fatigue was maked with Bangsbo modified futsal fatigue protocol. position sense of ankle joint was measured with Isokinetic Biodex set in 15degree inversion and eversion and fatigue with borg scale before and immediately after of doing protocol. Data was analyzed with dependent T test and significance level of (p= 0/05). Results The results showed after fatigue, error rate of the players has significantly increased in the reconstruction of the angle. Based on the information obtained from the Borg scale, the fatigue of players in the post test (17. 81± 2. 2) was significantly more than pretest (7± 0. 81). (P=0. 000& Es=1. 54). Conclusion fatigue makes change in position sense of ankle joint. In present study used from modified futsal fatigue protocol for made fatigue in participant. The result showed after doing fatigue protocol, increased error rate of position sense. Therefore probability of injured increased.

Aim The purpose of this study was to examine the immediate effect of two types of dynamic stretching with different speeds after functional fatigue on maximum knee flexion during landing in professional male volleyball players. Methods Thirty-six professional male volleyball players in Kerman with age of 18-23 year old (age: 20. 6 ± 2. 1 years, height: 185. 9 ± 6. 5 cm, weight: 77. 2 ± 8 kg) were objectively selected and randomly divided into 3 groups: dynamic slow stretching, dynamic fast stretching and control group (n=12 per group). In order to apply fatigue, functional fatigue protocol for volleyball and for recovery two types of slow and fast dynamic stretching were used. Results The mix repeated measure showed a significant decrease fatigue in the maximum flexion of the knee joint in the pre-test and post-test after fatigue in the all groups. However, after applying the recovery protocol, only slow dynamic group was showed significant increase in the maximum flexion of the knee joint in the pre-test and post-test (P = 0. 001). No significant difference among groups was found (P= 0. 430). Conclusion It can be concluded that slow dynamic stretching can be appropriate recovery method at the end of the competition and practice for athletes to remove negative effect of fatigue, especially for volleyball players. They can use slow dynamic stretching to improve the performance and prevent lower limb injuries, especially the anterior cruciate ligament. But the fast dynamic stretching is not an appropriate method for recovery in volleyball players.

Background and purpose: The purpose of this study was to determine the effect of training intervention (v. i. z swimming) on balance and systems involved in balance especially in adolescents with hearing impairment and also with vestibular deficiency. Materials and methods Twenty-four deaf girls from exceptional schools in Pakdasht country, Tehran, were present as an accessible sample in this study. After obtaining the code of ethics IR. UT. SPORT. REC. 1396021 and informed consent, the subjects were randomly divided into experimental and control groups. At first, a pre-test of balance was performed under four different conditions of sensory involvement including simultaneous disorder of proprioception and vestibular, visual and vestibular, proprioception and visual and without any interference with the Biodex device. Then, an experimental group of 12 individuals (Mean age 15. 50 ± 2. 8) for 8 weeks (having 3 sessions per week) underwent swimming training exercises and 12 person of control group (Meanage 15. 50 ± 1. 9) which did not have any activity in any field. After completing the intervention training period, post-test was performed similar to pre-test. Results After confirming the distribution of data and homogeneity of variances, the results of multivariate analysis of variance indicated that swimming exercises had a significant effect on balance without sensory interference and vestibular balance (P = 0. 0005). Conclusion Therefore, it is suggested that this method of rehabilitation be used in health centers, hospitals, rehabilitation centers, exceptional schools and deaf schools in order to improve the balance of the deaf.

Background and Aim One of the common problems among patients suffering from Osteoarthritis, is knee instability, which can effect on patients physical functional. The purpose of this study was to investigate of self-report instability on gait parameters, dynamic gait, balance and quality of life in patients suffering from Osteoarthritis. Materials and methods In this cross-sectional study, 68 patients with Osteoarthritis after confirmed by specialized and having inclusion criteria, were participated in the study. 31 patients with self-report instability put on instability group and 37 patients without put on without instability group. Berg test for balance, foot trace for gait pattern, WOMAC for function, SF36 for quality of life, Up and Go test(UGT)-going up and down stairs-40 meter walking for physical function, were used. to compare means, Independent sample t-test with α =0. 05 and confidence interval %95 was used. Results the results showed that a significant difference in Berg scores between groups (p=0. 016). As well it was significant between groups in 3 parameter related to daily physical activities UGT (p=0. 016), going up and down stairs (p=0. 027 and p=0. 05). About WOMAC, Groups had significant difference only in the joint stiffness (p=0. 04). But, two groups hadn’ t difference in dynamic gait indicator parameters, gait pattern and quality of life (p>0. 05). Conclusion based on the effect of instability on some key factors of daily physical activities and prevention of falling in Osteoarthritis patients, it is recommended that specialists and physiotherapists identifying patients with osteoarthritis with instability before any rehabilitation program and intervention to design right solutions of improvement.

Background and aim In addition to psychological effects, addiction to opioids can cause negative effects on physical aspects, central nervous and musculoskeletal system and the body posture as well. Poor posture causes pressure on the different structures of the body and makes the internal and vital organs vulnerable. Materials and methods 30 male and 30 female methadone maintained drug dependants participated in the research voluntarily. Subjects were selected purposefully. 30 healthy women and 30 healthy men were homogenous in term of age, height, weight and BMI with the addictive samples selected as control groups. Subjects’ thoracic kyphosis and lumbar lordosis were measured by flexible ruler by Hopenfeld method. The cervical spinal curvature was measured by using the Photogrammetry method. Results Based on the findings of this study and the results of MANOVA, there was a significant difference among cervical spine posture (p=0. 0001), thoracic kyphosis (p=0. 0001) and lumbar lordosis (p=0. 005) of addicted males and females and healthy males and females. Conclusion Based on the findings, there was a large effect size and a significant difference among the spinal curvature of the addicted males and females and the healthy ones. Finally, it was concluded that drug dependence affected negatively on the spine of men and women.
