    Purpose

    Various kinematics and kinetics methods have been proposed for the assessment of jumping ability as a critical skill in professional volleyball players, but little is known about the accuracy and differences between these methods. Therefore, the objective of the current study was to answer the question “Is there any difference between the results of various kinetic methods in the assessment of block jump height in volleyball players or not?” 

    Methods

    Twenty-one healthy male junior volleyball players of the Iran national team performed the block jump task on a force platform. Three common formulas mostly used in literature based on kinetics output of force platform were selected for the comparison of resultant jump height. Descriptive analysis, Shapiro-Wilk test, and ANOVA were used for statistical calculations (p<0.05).

    Results

    The results showed no significant difference between the means of block jump heights measured based on different kinetic methods in volleyball players.

    Conclusion

    Formula calculation methods are very valid for measuring the jump height of the block jump and lead to very similar results for estimating jump height and are also replaceable with each other.

    Purpose

    The aim of this study was to evaluate the effect of strengthening the abductor and external rotator of the hip joint muscles on pain, thigh muscle strength, and lower limb kinematics in volleyball players with patellofemoral complications.

    Methods

    Twenty-four volleyball players with patellofemoral pain were randomly divided into the experimental and control groups. The experimental group received three sessions of strengthening exercises for the abductor muscles and external rotators of the hip joint using Traband for eight weeks. The control group received no training intervention. The pain was assessed by visual acuity scale, hip muscle strength by hand dynamometer, and lower limb kinematics using video analysis before and after the intervention. Samples included volleyball players with patellofemoral pain who had pain in one or both knees. If the pain was bilateral, the exercises were performed bilaterally on both lower limbs, but measurements were taken only from the lower extremity, which was most in pain. Analysis of covariance was used by SPSS software for statistical analysis.

    Results

    The results of this study showed that after training, in the experimental group, pain decreased and the strength of the abductor’s muscles and external rotator of the hip joint muscles increased. Knee dynamic valgus and pelvic drop were observed in single-leg squat only in the experimental group. 

    Conclusion

    The results showed that the strengthening of the hip joint can decrease the pain of volleyball players with patellofemoral, increase the strength of the muscles and change the kinematics of the lower limbs on the frontal plane, and this can be the mechanism of the effect of this intervention on the symptoms of pain.

    Purpose

    Kinesio-Taping (KT) is a new therapeutic approach for Shoulder Impingement Syndrome (SIS), which is common in swimmers. This study was performed to investigate the short- and long-term effects of KT on shoulder pain and functional stability in swimmers with SIS.

    Methods

    In this quasi-experimental study (randomized control trial), 28 swimmers with SIS were randomly allocated to the taping and control group. We used the Davis test and Upper Quarter Y-Balance Test (UQYBT) to assess the functional stability of the shoulder girdle and also the Visual Analog Scale (VAS) to assess pain. The data were gathered in three time points: pre-test, 20 minutes, and 72 hours after the procedure. For statistical analysis, we used repeated-measures analyses of variance with a significance level of α<0.05. The analyses were done in SPSS.

    Results

    The results showed that the taping group had a significantly improved in Davis test and UQYBT in the follow-up and the post-test and also significantly improved in VAS in the post-test compared to the control group. Also, the mean scores of pain, UQYBT, and Davis tests in the follow-up were significantly improved. The mean scores of the UQYBT and Davis test in the post-test were significantly better than those in the pre-test in the taping group (P=0.001). However, there was no significant difference between any of the time points in the control group (P<0.05).

    Conclusion

    Given the results, KT can provide a basis for reducing pain and improving the functional stability of the shoulder girdle of swimmers with SIS. KT can be used as a complementary treatment technique in people with shoulder impingement syndrome and prevent possible injuries in the area.

    Purpose

    The purpose of this study was to compare the effects of two different approaches of dual-task training and executive training on lower limb muscular activity in older adults with balance impairment.

    Methods

    This was a quasi-experimental study performed with a pre-test and post-test method. Thirty old adults (Mean±SD age=73.8±4.6 y, height=1.65±0.06 m, weight=69.17±12.67 kg) were randomly assigned to one of the three groups: two experimental groups included Cognitive Dual-Task training (CDT; participants did exercises under the dual-task condition with cognitive tasks, such as forward counting, simple visual search task, etc.) and Executive Function training (EF; included a mixture of 20 tasks involving working memory tasks, inhibitory and speed of processing tasks), and a control group. The training session lasted 45 min and was held three times a week for eight weeks. Gait muscle activity under single-task and Dual-Task (DT) conditions was recorded before and after training. 

    Results

    during the stance phase of normal walking, the amplitude of Electromyography (EMG) activity of right Tibialis Anterior (TA) muscle in the post-test was about 32% lower than that in the pre-test in the CDT group (P=0.011), and no statistically significant change was between pre- and post-training in the EF and control groups (P>0.05). During the swing phase of DT walking, the amplitude of EMG activity of the right Vastus Lateralis (VL) muscle in the post-test was about 15.5% higher than that in the pre-test in the CDT group (P=0.013), and in the right VL muscle during the post-test was lower than that in the pre-test in the EF group (P=0.01). In the CDT group, right ankle co-contraction during the stance phase in the post-test was statistically different from that in the pre-test. In all three groups, muscular EMG asymmetry demonstrated no statistically significant change between pre- and post-training measures (P>0.05).

    Conclusion

    Overall, both training groups showed similar muscular activity in the post-test than pre-test; however, in the EF training group, walking velocity improved more than that in the CDT group. Therefore, because of improvements in both walking velocity and muscle activities after EF training, this training mode is suggested for older adults.

    Purpose

    Developmental Coordination Disorder (DCD) is common among intellectual disability children that can worsen motor problems, especially motor skills. The purpose of the study was to examine the effect of combining core stability exercises with coordination exercises on motor proficiency of intellectual disability children with DCD.

    Methods

    The population was boys with intellectual disability and DCD studying in Golestan School of Tabriz randomly that were divided into two groups of 15 subjects in the experimental group and 15 in the control group. Motor skills were evaluated using the Bruininks-Oseretsky Test of Motor Proficiency-Short Form in the pre- and post-test. The experimental group performed three sessions (every week) of 60 minutes of combined core stability with coordination training for eight weeks. SPSS v. 21, dependent t-test, and analysis of covariance at the significance level of P<0.05 were used for statistical analysis.

    Results

    Comparing the means of the two groups showed a positive significant difference in running speed and agility (P=0.001), balance (P=0.001), two-way coordination (P=0.001), strength (P=0.001), upper limb coordination (P=0.001), response speed (P=0.001), speed motor vision control (P=0.001), upper limb agility (P=0.001), and the overall gross and fine motor skills scores (P=0.001) and the combined score of the short scale (P=0.001).

    Conclusion

    The results indicated that combining core stability with a coordination training program can be used to enhance the motor skills of DCD children with intellectual disabilities. Thus, sports coaches and experts, and specialists in other related fields are recommended to use these exercises to enhance the gross and fine motor skills of students with intellectual disabilities, especially those with DCDs.

    Purpose

    Electrotherapy is a common intervention for the rehabilitation of Bell’s palsy. Low-level Laser Therapy (LLLT) and Electrical Stimulation (ES) are two therapeutic interventions for Bell’s palsy that have been proven to be superior to conventional treatments. To date, no clinical trial has compared the effectiveness of these two interventions. This pilot study was done to compare the effectiveness of LLLT and ES in the management of acute Bell’s palsy.

    Methods

    This randomized clinical trial was done on 25 participants with acute Bell’s palsy who were randomized into two groups with 12 participants that received LLLT and 13 participants that received ES. All participants received 12 treatment sessions over two weeks. Sunnybrook Facial Grading System (SFGS) was used to assess facial symmetry and Facial Disability Index (FDI) for facial function. Outcomes were assessed at baseline and after two weeks.

    Results

    There was a significant improvement in SFGS and FDI scores within both groups (P<0.005). There was no significant difference in SFGS and FDI scores between groups (P=0.164; P=0.423).

    Conclusion

    There is no difference between LLLT and ES in improving facial symmetry and function in acute Bell’s palsy.

    Background

    Compared with other sports, Soccer is an activity with a relatively high incidence of injury. To decrease the number of injuries, prevent early retirement, and provide a healthy and safe environment for players, preventive programs are highly recommended. The aim of this study was to investigate the effect of specific Soccer Sports Metrics Training (SSMT) on landing error scoring systems (LESS) and dynamic balance in soccer players.

    Methods

    This study was a randomized controlled trial. The subjects of this study were 29 soccer players with three years of experience in soccer clubs. Subjects were randomly divided into training (n=14) and control (n=15) groups. The TG performed SMST for six weeks. The CG continued normal exercises. The LESS and the Y balance were used for assessing landing errors and dynamic balance. Data were analyzed using Analysis of covariance (ANCOVA) test (P≤0.05).

    Results

    The results of ANCOVA showed a significant difference between the scores of LESS between the TG and CG after six weeks training (F= 48.23, P= 0.00). Also, results for the Y balance test showed a significant difference between the left foot (F= 31.78, P= 0.00) and the right foot (F= 34.33, P= 0.00).
     

    Conclusion

    as a result of the relationship between landing error and dynamic balance with knee injuries, especially ACL rupture, it is recommended that soccer players use SMST to prevent injury.
