Background: Badminton is individual non contact sports that require quick movements like jumps, lunges, rapid arm movements and quick change in direction to hit a shuttlecock across the net from any postural position. The scapula plays a vital role in shoulder function. The role of the scapula in shoulder function is the ability to coordinate motion between scapula and humerus. Pain and stiffness is the most common injury sustained by the badminton players. The abnormal scapular biomechanics that occurs as a result of this dysfunction create imbalance between the agonist and antagonist muscles and predispose the shoulder to injuries. The majority i.e. 75% of injuries in badminton is described as overuse injuries, and the upper extremities account for around 30%.
Purpose: To find the scapular associated impairments in Badminton players.
Methods: Using cross sectional research design, 30 badminton players were randomly included in the study. Demographic data (name, age, gender) was collected. The following outcome measures were evaluated: Various test for core- stability and shoulder stability, pectoralis minor length (PML, John B 2008), posterior soft tissue tightness (PST, Lin et al 2006), glenohumeral external and internal rotation, scapular muscle strength , closed kinetic chain upper extremity stability test (Todd 2009), neural tissue tightness of upper limb , scapular dyskinesia test , core stability and strength testing, lateral scapula slide test, functional throwing performance index.
Results: Badminton players when compared against dominant and non dominant did not show any statically significant difference in pectoralis minor length. When scapula dyskinesia test was performed 10 % reported abnormality, whereas 90% reported as normal. We found significant difference in the posterior soft tissue tightness (horizontal adduction range) between dominant (mean=26.8) and non dominant (mean=31.7) side among badminton players as well as increase external rotation range (dominant mean = 100.50, non dominant mean= 98.6) and internal rotation range (dominant mean = 51.37, non dominant mean= 53.2). Scapular muscle strength comparison between dominant and non dominant side in badminton players showed middle trapezius and internal rotators having significant static difference, lower trapezius and external rotators having significant difference and serratus anterior and upper trapezius did not show any statically difference. We found no abnormality in neural tissue tightness test of upper limb.
Conclusion(s): The scapular associated impairments in badminton players were posterior soft tissue tightness, increased external rotation range of motion, and decreased internal range of motion and weak scapular muscles.
Implications: In our study, with this assessment protocol the scapular associated impairments can be identified in the early stages. So the impairments can be addressed and early intervention is possible which can help in preventing injury.
