CORRELATION OF THORACO-LUMBAR SPINE RANGE OF MOTION WITH SCAPULAR DYSKINESIA IN PACED CRICKET BOWLERS

Abstract

Background: Cricket is a universally loved sport and played all over the world, Fast bowling is one of the most well regarded skill which involves high impact shoulder and spine mobility.Injuries to Shoulder and Spine are the most common ones. Study Purpose: Shoulder and Back injuries are the two most common injuries in paced bowlers. Improper and incoordinated movements at these joints could be one of the attributing cause for the injuries. Thereby, this study was taken into consideration to find out whether there exists any correlation between thoraco-lumbar spine range of Motion and scapular dyskinesia in paced cricket bowlers. Study Design: Crossectional Study design. Method: A research was conducted among paced bowlers training in an academy in Pune of Age 13-25 playing for more than a year. After taking consent from the player, scapular dyskinesia was measured with lateral scapular slide test and thoraco-Lumbar ROM was measured by dual inclinometer(flexion, extension, lateral flexion dominant and non dominant side, lateral rotation dominant and non dominant side) Both the readings were compared and analyzed by pearsons test using SPSS 16 software. Results: It was found that, there was a moderate negative correlation between scapular dyskinesia and thora-columbar lateral flexion ROM on non dominant side (r=-0.568 and p=0.001) and there was a substantial negative correlation of scapular dyskinesia and lateral rotation ROM on the non dominant side(r=-0.645 and p=0.001), while there was no correlation of scapular dyskinesia and thoracolumbar flexion, extension ROM and lateral flexion, lateral rotation ROM to the dominant side. Conclusion: Thus, there exists a negative relationship between scapular dyskinesia and thoracolumbar lateral flexion and rotation on the non dominant side. Thus a good bowling technique which is coordinated and biomechanical correct at scapula and thoracolumbar spine might cause lesser injuries
