Comparison of Two Protocols for Patellofemoral Pain Syndrome (PFPS)
The patellofemoral pain syndrome (PFPS) is defined as a painful complaint in the anterior aspect of the knee, although peripatellar pain and / or retropatellar are also common. In general, conservative treatment is the initial option of choice for patients with PFPS, however, the lack of a specific causal factor makes it difficult to choose the best treatment so early. This way, the purpose of this study is investigate the effects of the quadriceps femoris strengthening versus hamstring stretching in patients with pattellofemoral pain.

- Numeric Pain Rating Scale [ Time Frame: Participants will be followed for the duration of 8 weeks. ] [ Designated as safety issue: Yes ]Pain was assessed using an 11-point numeric pain rating scale (NPRS), on which 0 denoted an absence of pain and 10 denoted unbearable pain.
- Lysholm Scale [ Time Frame: Participants will be followed for the duration of 8 weeks. ] [ Designated as safety issue: Yes ]This questionnaire is made up of eight items with objective response options. The final score is expressed in nominal and ordinal form, as follows: 95 to 100 points - excellent; 84 to 94 points - good; 65 to 83 points - fair; and 64 or fewer points - poor.
