Background: Shoulder pain and injuries (e.g., shoulder impingement syndrome) are common among badminton players from amateur to elite levels. Kinesiology taping (KT) may improve shoulder muscular performance in athletes with shoulder impingement syndrome because it may increase proprioceptive feedback and the neuromuscular performance of the shoulder muscles.
Purpose: This study aimed to confirm the influence of kinesiology taping (KT), various overhead stroke techniques, and their interactions on shoulder girdle muscle activity and on sports performance in amateur badminton players with shoulder impingement syndrome.
Methods: Twenty-five amateur badminton players with shoulder impingement syndrome volunteered to participate in the study. Each participant was exposed to two KT conditions (no taping and taping) while performing four badminton overhead strokes (defensive clear, attacking clear, smash, and drop shot). Surface electromyography (EMG) was used to evaluate the activity of the pectoralis major, anterior deltoid, infraspinatus, and latissimus dorsi muscles on the affected side. The EMG data were expressed as a percentage of the EMG amplitude recorded during a maximal voluntary isometric contraction of the respective muscles. The shuttlecock speed was also measured via video analysis.
Results: The pectoralis major, anterior deltoid, infraspinatus, and latissimus dorsi EMG amplitudes were greatest during smashes (p 0.05), followed by attacking clearances (p 0.05) and defensive clearances (p 0.05). Drop shots induced the lowest EMG amplitudes in all the shoulder girdle muscles (p 0.05). No significant main effect of the KT condition or KT-badminton stroke interaction effects were found (p > 0.05).
Conclusion(s): The use of KT conferred no immediate benefits in improving shoulder girdle muscle activity or sports performance in amateur badminton players with shoulder impingement syndrome. Shoulder girdle muscle activity and sports performance were primarily influenced by the badminton overhead stroke techniques. Smashes generally caused the greatest shoulder girdle muscle activity and the fastest shuttlecock speed, followed by defensive and attacking clearances, and drop shots caused the least shoulder girdle muscle activity and the slowest shuttlecock speed.
Implications: KT has no immediate benefits in shoulder kinetics or sports performance in badminton players. Therefore, KT is not recommended for badminton players with shoulder impingement syndrome. Badminton overhead stroke techniques have the greatest influence on shoulder kinetics and sports performance.
