RESUMO
BACKGROUND: Patellofemoral pain syndrome (PFPS), characterized by retropatellar and peripatellar pain, is a common disorder affecting young women. Treatment has included exercise-based therapy and taping techniques for rapid reduction of symptoms and pain. Although Kinesio Taping® (KT) has been studied as adjunctive therapy, evidence on its effectiveness is limited and conflicting. OBJECTIVE: To determine the feasibility of performing a double-blind randomized controlled trial (RCT) using KT® for PFPS treatment and to determine an ideal sample size. DESIGN: Double-blind, randomized, controlled pilot study. METHOD: Forty-three women (aged 18-45 years) with at least a 3-month history of PFPS were randomized based on the mechanical correction techniques: using KT® for patellar medialization (KT-PM), using KT® for lateral rotation of the femur and tibia (KT-LRFT), and the control group (CG). All groups underwent the same muscle strengthening and motor control procedures for 12 weeks. Knee pain and function were evaluated at baseline, at 6 weeks, at treatment completion (12 weeks), and during the 12-week follow-up using the numerical pain rating scale (NPRS) at rest and during effort, Anterior Knee Pain Scale (AKPS), and single jump hop test. RESULTS: There were clinically significant differences between the KT-LRFT and the CG in terms of AKPS and NPRS scores during effort at the 6-week and 12-week follow-ups. All groups (within group) showed a significant improvement in pain and function. CONCLUSIONS: A complete RCT using KT® for the treatment of PFPS is feasible with some changes regarding outcome measures and treatment protocols.
