Effect of early progressive isotonic exercise therapy on static balance control of patients with total knee replacement

Purpose: Knee osteoarthritis [OA] is believed to be an important risk factor for falling. Total knee replacement [TKR] is a commonly used choice when other methods are not satisfactory. Proprioception impairment, risk of falling and balance disorder are within the main complications of this method. While multiple protocols have been suggested for TKR, efficacy of early isotonic exercise therapy aimed at improving body balance after TKR has not been thoroughly investigated

Methods: In this quasi-experimental study, twenty female patients with severe OA, sampled by non-randomized convenient method were randomly and equally in number assigned into either "routine"or "early isotonic exercise" groups. The subjects were undergone TKR surgery. The rehabilitation process [being the same for both groups until the second week] was initiated the day after surgery and lasted for 6 weeks. From the second week, the experimental group received progressive, isotonic exercises, in addition to the routine rehabilitation protocol. Static balance was assessed prior to surgery and after the rehabilitation process in both groups by Sharpened Romberg tests

Results: In both groups, static balance was significantly enhanced after surgery and rehabilitation [P=0.000]. Prior to surgery the groups were indifferent according to their static balance scores [P=0.423] but, after surgery and rehabilitation, the patients receiving early isotonic exercise in addition to routine physical therapy, were significantly in better balance condition comparing the control group [P=0.000]

Conclusion: Routine physical therapy with and without early isotonic exercise therapy enhances static balance but, the balance improvement was more pronounced with this type of exercise. Early administration of isotonic exercise therapy in addition to the routine physical therapy program may enhance balance and thus prevent fall in patients with TKR

[ effect of theraband training on position sense of internal and external rotator muscles in male athletes with shoulder impingement syndrome]

Objective: This study evaluated the effect of theraband training on Position sense of internal and external rotator muscles in male athletes with shoulder impingement syndrome

Materials and Methods: In this semi-experimental interventional study 30 cases of men with Shoulder syndrome with age range of 20 to 30 years participated. They were divided in test and control groups, each group including 15 people through non-random and purposeful method Biodex System 3 Made in America was used to measure position sense of internal and external rotator muscles. For data analysis independent 7 paired t-test was used in SPSS software [version 21]

Results: The experimental group showed significant improvement after six weeks of theraband training in the internal and external rotator muscles in three 90,45,0 degree angle at a significance level of 0.05 [P=0.05]

Conclusion: The results of this study showed that of theraband training resulted in improved position sense of internal and external rotator muscles in male athletes with impingement syndrome thus, the benefits of these exercises can be used widely in team sports and also for easy and quick rehabilitation of patients

[Shoulder range of rotation analyze in overarm and underarm throwing athletes in before injury rehabilitation]

Since the range of motion dysfunctions disturbs skillful throwing function as one causes of shoulder pain and essential factors of throwing in overarm and underarm throwers' shoulder, the purpose of this study was to compare dominant and non dominant shoulder range of rotation among volleyball, bowling players and nonathlete women before an injury. In this non-experimental, cross sectional study, 45 women in 3 equal groups of nonathlete, volleyball and bowling players at the range of 20 to 30 years of age were recruited and their shoulder range of rotation was measured by goniometer. For data analyzing, descriptive statistic such as mean, standard deviation, and for reliability analyzing, Correlation Coefficient were performed. Kolmogorov-smirnov and Leven's tests for assessing the data normality and groups variance equality, paired T-test for comparing dominant and nondominant sides, One-way ANOVA for comparing shoulder range of rotations among bowling, volleyball players and nondominant women [significant level p<0.05] were also performed. Athletes demonstrated a significant less Internal Rotation [p=0.00] and greater External Rotation [p=0.02] in dominant shoulder compared to nondominant and non-athletes [p=0.00] shoulder. However, there were no significant differences between dominant, nondominant shoulder [p=0.07 volleyball, p=0.30 bowling players] and among groups [p=0/23 nonathletes and volleyball, p=0.07 nonathletes and bowling players] in total range of motion. In addition, no significant difference was found in examining variables between volleyball and bowling players [p=0.80 external, p=0.82 internal, p=0.54 total rotation]. According to the role of range of motion in joint injuries rehabilitation, how changing in it before thrower shoulder injuries, challenges the kind of rehabilitation after injuries.In order to study the results, we can say thrower shoulder range of rotation shifts toward greater external and less internal rotation as a result of micro truma that caused by repetitive throwing and these changes that are not related with kind of throwing [overarm or underarm] could be one of the probable causes of athletes' shoulder pain
