Abstract
Background: Patellofemoral pain syndrome (PFPS) is the most common overuse syndrome in athletes. The aim of this study was to compare the effects of taping and elastic bandage on postural control in athletes with PFPS. Materials and Methods: Fifteen males and 19 females with PFPS participated in this clinical trial study for more than 1 month and were randomly divided into two groups; group 1 was taped based on McConnell method and in group 2 elastic bandage was used. The static postural control in both groups was measured before and after interventions using the force- plate through measuring the center of pressure (COP) and estimation of differences between center of pressure and center of mass (COP-COM moment arms) in AP and ML directions. Moreover, dynamic postural control was measured by star excursion balance test (SEBT). Paired t-test and covariance analysis were used for analysis of the data. Results: Results indicated that after taping reach distances increased significantly (p< 0.05) in anterior, anterolateral, lateral and posterior directions but after elastic bandage reach distances increased in posterior, posteromedial and medial directions. After both taping and bandage, COP and COP-COM moment arm measures did not show significant differences. Conclusion: The findings of this investigation showed that in athletes with patellofemoral pain, taping and elastic bandage improved dynamic postural control. However, dynamic methods are successfully used to assess the effects of taping and bandage on postural control. Static variables compared with dynamic measures potentially lack the ability to detect subtle differences of postural control in athletes with PFPS. [GMJ. 2015;4(3):82-89]

Findings of this study revealed that applying McConnell taping and standard elastic bandage improved dynamic postural control but it did not have any effect on static postural control
Findings of this research indicated that reach distances of star excursion balance test (SEBT) significantly increased in the anterolateral, anterior, lateral and posterior directions due to application of taping, but standard elastic bandage caused an increase in reach distances in the posterior, posteromedial and medial directions
Summary
Patellofemoral pain is a common injury among young athletes. Up to 40% of clinical visits for knee problems are attributed to patellofemoral pain [1]. To the best of our knowledge, no study has compared the effects of taping and standard elastic bandage on postural control in athletes with PFPS through dynamic and static methods concurrently. The main objectives of this study are to firstly investigate the effects of McConnell taping and elastic bandage on static and dynamic postural control and secondly to compare the ability of these methods to detect differences of postural control after intervention among athletes with PFPS. This study hypothesized that: 1) taping and elastic bandage application in athletes with PFPS improve postural control ability, 2) postural control assessment by SEBT and COPCOM moment arm measures has a more potential to detect postural control differences after intervention. Static variables compared with dynamic measures potentially lack the ability to detect subtle differences of postural control in athletes with PFPS. [GMJ. 2015;4(3):82-89]
