Background: The Patellofemoral pain syndrome is the most common condition of anterior knee pain, with high incidence, chronicity and treatment cost.
Purpose: Evaluate the effects of patellar taping when applied with and without mechanical action in pain, functional tasks and muscle performance in women with Patellofemoral Pain Syndrome.
Methods: Clinical trial randomized controlled blind with sample of 30 women divided into control group (CG), the placebo group (PG) and experimental group (EG). Evaluation and instruments were: pain during maximum strength test (Visual Analogue Scale VAS), pain during functional tasks (up and down stairs and squat) and muscle strength (isokinetic dynamometer). All groups performed the evaluations proposed without the taping (t0) was performed taping application in PG and GE and reevaluation immediately after this application (t1). The pain during the functional tasks was measured again after 24 hours with use of the taping (t2). Data were analyzed using the Statistical Package for Social Sciences (SPSS) version 23.0 and applied the tests: Shapiro-Wilk, t student, ANOVA and Friedman. Was adopted p 0.05 significance level.
Results: The average age in the CG was 22.4 (± 2.3), the PG was 23.6 (± 8.2) and GE was 22.8 (± 2.2). It was found no significant difference in pain during maximum intragroup strength test (GC, GP and GE, p> 0.05), however the assessment of pain during functional task of up and down stairs there was a reduction of pain in t2 in relation to t0 (p = 0.008). In assessing muscle strength peak torque of GC extensors reduced at time t1 relative to t0 (p = 0.01) and in the other groups (PG and GE) this peak torque remained stable (p> 0.05). In all comparisons between groups (GC, GP and GE) there were no significant statistical differences in pain during maximum strength test, during functional tasks or peak torque and total work flexor and extensor knee.
Conclusion(s): The patellar taping with mechanical action proved to be an effective method in reducing pain of functional tasks up and down stairs 24 hours after its application (t2). There was no effect on muscle performance, although the placebo taping or therapeutic taping prevented the reduction of peak torque in the reassessment of muscle performance.
Implications: The results of this study will establish a reference for physiotherapists their behavior in conditions anterior knee pain, since taping can be an effective adjunct in pain reduction and maintenance of muscular strength. In addition, patients and the scientific community will benefit from the findings of this study.
