Conditions
Brief summary
Patellar tendinopathy is a very common condition among athletes, especially those involved in jumping skills. The study will be conducted in two groups. One with a rehabilitation programme based on shock wave, stretching and neuromuscular exercise based on eccentric contractions. The comparison group will be a placebo rehabilitation consisting of stretching and manual therapy of accessory muscle groups. Outcomes will assess pain scale, tendon thickness and neuromuscular performance.
Interventions
The 8-week intervention includes eccentric training, static stretching, and extracorporeal shock wave therapy (ESWT), conducted five days per week. Initial sessions are supervised by physiotherapists at the University of Córdoba; subsequent sessions are home-based.
Eccentric Training:
Single-leg decline squats (25°) to 90° knee flexion, 3 sets of 10 reps, 6 times/week. Pain monitored via VAS; load increased by 5 kg if VAS less than 3. Adherence tracked with participant diaries reviewed weekly.

Adherence tracked with participant diaries reviewed weekly. Static Stretching: Quadriceps and hamstring stretches before and after training (30 seconds per muscle). Total: 2 minutes/session. Initially supervised, then self-administered. Recorded in the same exercise diary. ESWT: Five sessions over 8 weeks (1x/10 days initially, then twice in weeks 6 and 8) of 10 minutes duration. Delivered by a physiotherapist using Storz MP100 (2000 impulses, 4 Hz, 0.15 mJ/mm²). Attendance recorded by the therapist.
