Correlation between core stability and scapulohumeral rhythm in badminton player-An observational study

Abstract

Background: During functional activity core stability helps in maintaining balance of forces to and from extremities. The co-ordinated movement of the scapula and humerus help in proximal to distal activation of kinetic chain. Overhead motion in badmintion player requires coordinated movement from feet to hand, which is activated by core muscle. Hence, the present study is planned for correlation of the core stability and scapulohumeral rhythm in badminton player. Objective: The purpose of the study was to correlate the core stability and scapulohumeral rhythm in badminton player. Methodology: The study includes 40 badminton players were randomly included in the study. Demographic Data (name, age, gender) was noted. Core stability and strength testing was performed to assess the core stability. Inclinometer was used to assess scapulohumeral rhythm. Participants under went through lateral scapular slide test, Functional throwing performance index, close kinetic chain upper extremity test and scapular muscle strength testing. Result: The correlation was analyzed by Karl Pearson’s correlation coefficient test. The result showed a positive correlation between core stability and scapulohumeral rhythm in outcome measure core stability and strength testing, scapulohumeral rhythm, lateral scapular slide test, Functional throwing performance index, close kinetic chain upper extremity test and scapular muscle strength testing. The level of significance was set as p
