Neuromuscular Training Compared to Progressive Resistance Training for Patients With Anterior Knee Pain

The primary aim of this randomized control trial is to investigate patients' with anterior knee pain if a neuromuscular training program (NMT) has better results in pain and functionality, than an ordinary progressive resistance training program (PRT). Pain will be measured via a visual analog scale for pain (VAS) and functionality via questionnaires such as Kujala and the Greek version of the Modified Baecke Questionnaire (mBQ) and functional tests such as the Anterior Lunge test, Step up/down, squat, balance and reach test. The secondary aims are to investigate the: 1. Hip and knee muscles strength, which will be measured with the Kinvent K-Push dynamometer. Strength will be measured before and after the rehabilitation programs (at baseline and after 8 weeks of intervention). 2. Balance, will also be measured to see the effects of the NMT program. 3. Kinesiophobia, which will be measured with the Tampa Scale 4. Dynamic Knee Valgus, via the Single Leg Landing and Single Leg Squat tests
