Abstract	ABSTRACT Background: Badminton is an overhead sport which can cause mechanical stress on the shoulder joint because of repetitive movements such as smashes, clears, and serves. Repeated overhead activity can reduce dynamic shoulder stability, reduced neuromuscular control, and can affect sports performance. Physiotherapy interventions combining plyometric training with shoulder muscle strengthening may enhance shoulder stability and improve functional performance among badminton player. Objective: To evaluate the effectiveness of a six-week physiotherapy intervention combining plyometric training and shoulder muscle strengthening exercises in improving shoulder stability and upper-limb functional performance in a recreational badminton player. Methodology: A single case study was conducted on a 23-year-old recreational badminton player who was presented with reduced shoulder stability and fatigue while performing repeated overhead movements. Shoulder stability and upper-limb performance were assessed using the Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) and Plate Tapping Test (PTT). The participant underwent a supervised six-week physiotherapy intervention consisting of plyometric training and shoulder strengthening exercises, given 3–4 sessions per week. Pre- and post-intervention outcomes were compared to evaluate the effectiveness of the intervention. Results: Following the intervention, the CKCUEST score improved from 20 to 24 repetitions, indicating enhanced dynamic shoulder stability and upper-limb endurance. The Plate Tapping Test time improved from 14.0 seconds to 11.8 seconds, reflecting better speed, coordination, and neuromuscular performance. The participant also reported improved confidence during overhead strokes and reduced fatigue while playing badminton. Conclusion: This case study showed a combined effect of upper-limb plyometric training and shoulder muscle strengthening exercises may improve dynamic shoulder stability, coordination, and functional performance in recreational badminton players. Further studies involving larger sample sizes are recommended to confirm these findings.
