The aim of the trial is to compare the efficacy of extracorporeal shock wave therapy (ESWT) versus neuromuscular training (TR) in reducing pain in women with patellofemoral pain (PFP). Women with PFP will be randomly divided into two therapeutic groups: ESWT and TR. The ESWT group will undergo extracorporeal shock wave therapy to the iliotibial band and tensor fascia latae. The TR group will be treated with neuromuscular training. The women's gait will be analysed and the strength of hip abductors and internal rotators will be measured. Additionally, the women's pain and health status will be assessed with the visual analogue scale and the Lysholm Scale. Outcomes will be registered at baseline, and then at five weeks and at three months post-therapy

Each session lasted 30 minutes and consisted of three sets of exercises with 20-30 repetitions. Emphasis was placed on proper knee alignment during exercise. Most of the women exhibited excessive medial rotation and adduction of the femur, resulting in knee valgus, although knee varus was also observed. The women were instructed how to correct their abnormalities using mirrors as visual feedback. All exercises were completed without pain. If the exercises were too easy, the level of difficulty was increased individually in accordance with the rehabilitation protocol
ESWT will be applied to the iliotibial band and tensor fascia latae muscle with the following parameters: pressure - 4.5 bar, emission frequency -8 Hz, number of pulses per dose -2,500 per session

RECRUITINGVisual Analog Scale is used to assess the subjective Pain.
The participants are asked to make a mark on a 10 cm line that corresponds to the perceived maximal pain, peripatellar or retropatellar, they experienced during any activity or position (0 = no pain, 10 = the worst pain possible)
Time frame: Outcome measures are obtained at baseline (pre-intervention)

Gait analysis using the Zebris FDM-TDL instrumented treadmill with pressure sensors.
The women walk on the treadmill barefoot for three minutes in order to become accustomed to the speed belt. After that time, the angles of the joints are measured for 30 seconds. Internal rotation is demarcated at the highest peak in midstance when the contralateral limb is in the terminal stance (toe-off phase). Hip adduction is determined at the highest peak in midstance

Muscle strength is tested using the Micro Fet Handheld Dynamometer.
Muscle strength of lateral rotators, abductors of the hip is tested. Three repetitions of muscle strength testing are performed with two 30-second intervals. The participants a of re asked to press against the Dynamometer with the maximum effort for 5-7 seconds.
