Abstract
Purpose: Neuromuscular and biomechanical factors in ACL injuries are among modifiable risk factors. The purpose of the present study was to evaluate the effect of feedback and feed forward neuromuscular training on balance and isometric strength in female basketball players with a high risk of injury in Kerman.
Method: The present research is semi-experimental, prospective study and the subjects selected objectively based on inclusion and exclusion criteria.  Twenty women basketball players of Kerman city purposely selected and who were randomly divided into two groups of feed forward (age=15.73 ±0.78, weigh =61.38±9.09, height = 164.40 ±6.68) and feedback (age=14.70±1.33, weigh =56.31±8.38, height = 161.66±6.02) The training program designed based on the previous studies and conducted during 8 weeks, three sessions per week (each session 15 to 20 minutes) under the supervision of the examiner. Dynamic balance and isometric knee strength was measured using Biodex system and MMT device. One way ANCOVA was used for data analyze.
Result: The results showed significant differences between pre-post test balance Overall Stability index, internal/external index and Anterior/Posterior index (P=0.001).Significant difference was observed in the strength of quadriceps muscle and hamstring muscle between the two groups of feedback and feed forward exercises (P≥0.05). Also, the results of the paired sample t-test showed that Overall Stability in the feedback  and feedforward group (0.345% and 0.19%), Balance Anterior/Posterior in the feedback  and feedforward group(0.409% and 0.22%) and Balance Medial/Lateral in the feedback  and feedforward group(0.427% and 0.22%) has significantly improvement compared to the pre-test (p<0.002).Isometric Quadriceps strength in the post- test showed an significantly improvement of 2.16% in feedback group and 1.82% in feedforward group compared to the pre-test (P=0.001). Isometric hamstring strength in the post- test showed a significantly improvement of 2.07% in feedback group and 1.95% in feedforward group compared to the pre-test (P=0.001).
Conclusion: It can be concluded that neuromuscular training can enhanced balance and isometric strength, of women and training with feedback has more important  than training with feedforward.

randomized controlled study of The Effect of Suspened Core Stability Exercises on Balance, Core Stability and Pain in The Female With Non-Specific Chronic Low Back Pain
Mrs Ranasadat Heydari, Dr Mansour Sahebozamani, Dr Fatemeh Karimi Afshar,
Volume 0, Issue 0 (11-2019)
Abstract
Introduction and Purpose: Non-specific chronic back pain(NSLBP) is one of the main problems of the health community, which has a high prevalence. Therefore, the aim of this study is to investigate the effect of 8 weeks of suspended core stability exercises on the core stability, pain level, static and dynamic balance in the females with NSLBP.
Methods: In the present study, 21 females  with NSLBP were randomly divided into experimental and control groups. The Core stability, Pain level, Static and Dynamic balance were measured by valid tests of Core stability, Visual analogue scale (VAS) and Biodex balance system respectively. The SPSS25 software were used for data analysis.
Results: Based on the results of the study, unlike the control group, there was a significant difference in core stability, pain level, the static and dynamic balance variables from pre-test to post-test in the experimental group(P≤0/05). Also this difference was observed between the experimental and control groups(P≤0/05).
Conclusion: According to the results of this research and suspension system of TRX exercises, Core Stability Exercises with TRX straps which is not elasticity, may simultaneously improve core stability, static and dynamic balance and decrease pain in female with NSCLBP.
Durability Effects of Corrective Eexercise Program with Kinesiotaping and Physio Ball on EMG of Selected Shoulder Girdle Muscles in Boy with Upper Crossed Syndrome

Volume 20, Issue 24 (3-2023)
Abstract
 Postural disorders disrupt muscle activity and lead to joint dysfunction. Maintaining the function of the shoulder joint requires precise coordination and on-time action of muscles, and its dysfunction lead to change in the level of muscle activity, movement disorder. This study aimed to measure the effects of corrective exercise program with kinesiotaping and physio-ball and durability of these effects after 4 weeks on EMG of serratus anterior, middle trapezius and rhomboids major muscles among male young with upper crossed syndrome. Forty-five male young with upper crossed syndrome (control group: age:17.00±0.75, height 163.93±2.01, weight 65.20±6.51، BMI 25.10±2.76, corrective exercise with physio-ball: age 16.93±0.88, height 161.66±6.85 ,weight 63.40±10.09، BMI 26.84±3/04, corrective exercise with kinesiotaping: age 17.00± 0.92, height 161.53±7.25, weight 62.86±6/81, BMI 27.88±3/84) objectively selected and participated in this study. The training program designed based on the previous studies and conducted during 8 weeks, three sessions per week (each session 40 to 60 minutes) under the supervision of the examiner. EMG device was used to measure of the MVIC electrical activity of trapezius, rhomboids and serratus anterior muscle during external and internal rotation and extension of shoulder. After 4 weeks of the training, the post-tests were repeated.The one way ANCOVA was showed that the amount of electrical activity of the selected shoulder girdle muscles after eight weeks of testing in both experimental groups in the post-test and after one month inactivity test were significantly improved than the pre-test Group corrective exercise with physioball (serratus anterior p= 0.001,17.14%, middle trapezius p=0.001,15.79%  and rhomboids major p=0.001,14.81%), corrective exercise with kinesiotaping (serratus anterior p=0.001,17.14%, middle trapezius p=0.001,21.62% and rhomboids major p=0.001,20%) and durability in group of corrective exercise with physioball (serratus anterior p=0.001, 8.6%،, middle trapezius p=0.001, 7.9% and rhomboids major p=0.001, 7.4%) durability in group corrective exercise with kinesiotaping (serratus anterior p=0.001, 8.6%, middle trapezius p=0.001،16.2 % and rhomboids major p=0.001, 8%).  Considering the results of the present research, it can be stated that corrective exercise programs with kinesio taping and physioball have an effect on the electrical activity and durability of selected shoulder girdle muscles and And these effects are lasting even after 4 weeks. It is suggested to use this program of corrective exercises for male students with upper crossed syndrome to improve their shoulder girdle muscles strength.

Volume 21, Issue 25 (9-2023)
Abstract
The shoulder complex as one of the most moving joints of the body frequently was used by overhead sports athletes. Thus, musculoskeletal screening such as assessment of the range of motion (ROM), and strength variables can be useful to injury prevention strategies and further the development of conditioning and rehabilitation programs. The purpose of this study is to compare selected variables and the ratio of ROM and strength in volleyball, handball, and badminton players. A total of 36 athletes with similar physical characteristics (volleyball: age=26.65±4.56 y, weight=91.07±7.91 kg, height=185.14±12.25 cm; handball: age=27.29±3.12 y, weight=90.11±6.38 kg, height=183.52±9.67 cm, and badminton: age=26.01±4.29 y, weight=87.85±4.59 kg, height=182.38±10.74 cm) were selected to participate in the current study. A Leighton flex meter and hand-held dynamometer were used respectively to measure the ratio of ROM and strength.The results showed that the mean ratio of external(ER) strength to internal (IR) strength and ER ROM to IR ROM were significantly different between the three groups. The post hoc test revealed that badminton athletes had significant differences in all of the measured variables to both volleyball and handball athletes. But there were no differences between volleyball and handball athletes.In conclusion, preseason screening is vital in achieving optimal values on these measures and may reduce future shoulder injuries in overhead athletes.
