Patellofemoral pain syndrome (PFPS) is a major health problem and one of the most common causes of pain in the front of the knee in outpatients. The objective was to evaluate the effectiveness of a therapeutic physical exercise (TPE) program supervised by a physiotherapist using telematic channels in reducing pain and disability in a sample of 54 patients with PFPS in the Physiotherapy Service of the San José de la Rinconada Health Center (Seville). Subjects were evaluated pre- and post-intervention (4 weeks-12 treatment sessions). An analysis was made of perceived pain-using the visual analog scale (VAS) and the DN4 neuropathic pain questionnaire-and functional balance-through the Kujala Score test and the Lower Extremity Functional Scale. The supervised TPE program in patients with PFPS produced a reduction in pain: VAS F1, 52 = 8.68 (p = 0.005) η2 = 0.14 and DN4: F1, 52 = 69.94 (p = 0.000) η2 = 0.57; and in Lower Extremity Functional Scale (LEFS) disability: F1, 52 = 19.1 (p = 0.000) η2 = 0.27 and KUJALA: F1, 52 = 60.28 (p = 0.000) η2 = 0.54, which was statistically significant (p = 0.000 for penAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/patellofemoral pain syndromephysiotherapytherapeutic physical exerciseCOVID-19Exercise TherapyHumansPandemicsPatellofemoral Pain SyndromePrescriptionsProgram EvaluationTelemedicineresearch article33504042open access10.3390/ijerph180310481660-4601PMC7908506https://www.mdpi.com/1660-4601/18/3/1048/pdf?version=1611641530https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7908506/pdf
