Background: Groin pain is one of the common problems in multidirectional sports. The rate and complexity of injury have resulted in prolongation and high rate of this injury. However, there is so far no study that studies accurately the activity of muscle during dynamic and functional activities. Therefore, the aim of this study was to Comparing the Average amplitude of EMG (AEMG), co-contraction ratio (CCR) of selected thigh and thoracic muscle during turning in individuals with chronic groin pain and healthy individuals.
Materials and Methods: Surface electromyography was collected from the internal oblique/transversus abdominis (IO/TrA), multifidus (MF), adductor Longus (AL) and gluteus Medius (GM) for AEMG and CCR analyzed in 16 males with LSGP and 16 controls in four motion phases during 11 cycles of gait coupled with turning.
Results: statistical analysis indicated that in the mean muscle activity (AEMG) apart from the third phase in the muscle of the IO/ Tr.A muscle and in the second phase in the MF muscle in the trunk and in the third phase in the muscle of the AL and the fourth phase in the GM foot Left There was a significant difference in other phases. There was a significant difference in the cocontraction ratio, except in the second phase of the trunk and the fourth phase of the left foot in the rest of the phases.
Conclusion: it seems that in individuals with chranic groin pain, muscular activity and co-contraction have changed during turning, resulting in compensatory strategies and movement control defects, which may be a useful tool to predict LSGP occurrence in players with a history of groin pain.
