Background: Patellofemoral pain (PFP) is a chronic condition that usually results in long-term functional impairments both in adults and adolescents PFP has been found to decrease activity levels in individuals.
Purpose:The purpose of the present study was to investigate whether the additional use of electrical stimulation to an intervention program could result in greater improvements in the knee function and the level of pain compared with the intervention program itself.
Material and Methods: 22 women reported anterior knee pain symptoms clinically allocated in the patellofemoral region and confirmed through the patellar position, analyzed by magnetic resonance imaging (MRI). They randomly assigned into two groups with the same strengthening program. The experimental group used electrical stimulation combined with knee extensors and flexors strengthening exercises. The main outcome of the study was the visual analogue scale (VAS) in order to assess pain and the Anterior Knee Pain Scale (AKPS) to evaluate the functionality of the knee joint. All the outcomes were analyzed and compared pre and post a 6-weeks intervention period. Results: Statistically significant differences were found between the two rehabilitation groups at the end of the intervention period both in VAS (F1,20 = 44.083, p < 0.001) and functional assessment (F1,20 = 35.687, p < 0,001), suggesting that the conventional intervention program with the use of electrical stimulation is more effective regarding the pain degrees and the knee function.
