“…The use of "Russian electrical stimulation" associated with resistance exercises in patients with patellofemoral dysfunction (PFD), products strength gains and consequently pain relief. Augusto et al 14 verified that the intensity of muscle activation increases with the use of neuromuscular electrical stimulation (NMES), which makes it suitable in cases of PFD, since the greater incidence of this dysfunction is related to muscular imbalance, which corroborates the study by Bevilaqua-Grossi et al, 15 where a difference is observed in the reflex activation time between the Vastus Medialis Obliquus (VMO) and Vastus Lateralis Obliquus (VLO) muscles, both in healthy individuals and in patients with PFD.

Patellofemoral dysfunction is a fairly common deficiency among young individuals that primarily affects females and may be characterized by pain, swelling and retropatellar crepitation. The purpose of this review of literature from the period between 2005 and 2011 was to systematize knowledge in relation to the increase in quadriceps muscle strength and pain relief in patients with patellofemoral dysfunction, using neuromuscular electrical stimulation and resistance exercises. The inclusion criteria were intervention articles from the past six years, in English, Spanish and Portuguese, which used muscle strengthening and neuromuscular electrical stimulation for rehabilitation obtained through searches in the electronic databases Medline and Lilacs and in the Bireme library. The bibliographic search yielded 28 references, of which nine were excluded in accordance with the aims and inclusion criteria while 16 articles were selected for reading of the abstracts and subsequent analysis. Mediumfrequency Neuromuscular Electrical Stimulation (NMES) can be used in association with resistance exercises as an adjuvant in the treatment of patellofemoral dysfunction (PFD), both to achieve muscle rebalance and for pain relief.

“…Therefore, caution is recommended during clinical physical therapy practice when performing knee extension MVIC during the last degrees of OKC, when there is greater patellofemoral stress 26 . The VLO muscle requires further studies in people with PFPS given that the present study and other studies 16,27,28 , despite methodological differences, found that this portion does not appear to directly interfere in patellar lateralization and in imbalance. According to our results, these changes are attributed, in principle, to the VLL because there were no differences in the activation of this portion in the PFPS subjects.…”

Objectives: To analyze the electrical activity of the vastus medialis obliquus (VMO), vastus lateralis longus (VLL) and vastus lateralis obliquus (VLO) muscles of individuals with patellofemoral pain syndrome (PFPS) during maximum voluntary isometric contraction (MVIC) of lower leg extension with the knee at 30°; to assess pain using a visual analogue scale (VAS); and to assess patellar positioning using magnetic resonance imaging (MRI). Methods: Twelve women with PFPS and 12 clinically normal women were evaluated. They performed five MVICs of lower leg extension at 30° for electromyographic (EMG) analysis. Using MRI, the sulcus angle (SA), congruence angle (CA), patellar tilt angle (PTA) and patellar displacement (PD) were obtained. The following statistical tests were used: analysis of variance (ANOVA) for repeated measurements to assess EMGs; Mann-Whitney U test to analyze MRIs; Pearson's (r) correlation test between EMGs and MRIs; and one-way ANOVA to evaluate pain (p≤0.05). Results: In the PFPS group, there was greater electrical activity in the VLL than in the VMO. In both groups, there was greater electrical activity in the VMO and VLL than in the VLO. In the PFPS group, the MRI showed higher SA and lower CA values, and there was a negative correlation between the VMO and the PTA. Conclusion:The data suggest that, in individuals with PFPS, greater electrical activity in the VLL combined with an increased SA and a decreased CA may contribute to patellar instability.Key words: patellofemoral pain syndrome; electromyography.

“…1,4,5 However, many authors found no difference between the onset of electric activity of these muscles among individuals with and without PFPS. 1,4,6 Witvrouw et al 4 found that, during activities in open kinetic chain (OKC), the VMO muscle starts its activity later than VL muscle, and, according to those authors, this could lead to patellar misalignment during the activity, a finding consistent with Cowan et al 1 , who also found a difference of the onset of electric activity of patellar stabilizers. However, some studies evidence a simultaneous onset of electric activity between VMO and VL muscles when the leg is extended in OKC exercises, ruling out the hypothesis that the lack of synchronicity could be an etiological factor for PFPS.…”

“…Inclusion and exclusion criteria for groups with and without PFPS signs followed the recommendations by Coqueiro et al 11 and Bevilaqua-Grossi et al 6 The study was conducted according to the Resolution 196/96 of the National Health Council, being approved by the Committee of Ethics of the Institution. The common-mode rejection ratio (CMRR) was 93dB and the acquisition frequency, 2KHz.…”

Objective: To asses the onset (%) of patella stabilizer muscles during maximal isometric contraction exercises (MIC) in individuals with and without signs of patellofemoral pain syndrome (PFPS) in open (OKC) and closed (CKC) kinetic chain exercises. Method: Assessments were carried out on 22 women; ten with no complains of anterior knee pain, and 12 with PFPS signs during MIC in OKC and CKC with the knee flexed at 90º. The onset of the electromyographic activity of the vastus mediallis obliquus (VMO), vastus lateralis obliquus (VLO) and vastus lateralis longus (VLL) was identified by means of an algorithm in the Myosystem Br 1 software. The statistical analysis used was Chi-Square test and student's t test, which are both tests with a level of significance at 5%. Results: The VMO and VLO muscles presented a greater onset compared to the VLL during OKC exercises for both groups and for the PFPS group without CCF. No differences were observed between the groups. Conclusion: CKC and OKC exercises seem to benefit the synchronism of the musculature that supposedly benefits the patella stabilizer musculature, and can be recommended in physiotherapeutic treatment programs.
