Abstract Introduction: Palletofemoral pain syndrome (PFPS) is anterior knee pain that affects around 25% of the population at some point in their lives. Muscle weakness is one of the main causal factors related to PFPS. Objective: Conduct a quantitative analysis on the effectiveness of strength training at reducing pain in PFPS sufferers. Methods: An electronic search was conducted on the MEDLINE, Pubmed, EMBASE, Lilacs and Scielo databases for studies published between January 2005 and September 2014. The following descriptors were used: “patellofemoral pain syndrome”, “patellofemoral pain”, “retropatellar pain”, “exercise”, “exercise therapy”, “strength”, “rehabilitation”. Only randomized controlled trials (RCTs) that compared the effects of strength training to no exercise in terms of reducing pain among PFPS sufferers were included. Data were extracted by two independent authors using predefined quality indicators. Results: A total of 39 RCTs were initially identified in the search. However, only five met the inclusion criteria. Strength training exhibited a positive effect on PFPS (SMD = 0.85, CI: 0.45-1.25). However, high heterogeneity was observed between the studies (p < 0.05; I 2 = 68.3%). Conclusion: Strength training showed a statistically positive response in the treatment of PFPS.

Quadriceps Force

Context: Quadriceps weakness and inhibition are impairments associated with patellofemoral pain syndrome (PFPS). Lumbopelvic joint manipulation has been shown to improve quadriceps force output and inhibition, but the duration of the effect is unknown. Objective: To determine whether quadriceps strength and activation are increased and maintained for 1 hour after high-grade or low-grade joint mobilization or manipulation applied at the lumbopelvic region in people with PFPS. Design: Randomized controlled clinical trial. Setting: University laboratory. Patients or Other Participants: Forty-eight people with PFPS (age = 24.6±8.9 years, height = 174.3 ± 11.2 cm, mass = 78.4 ± 16.8 kg) participated. Intervention(s): Participants were randomized to 1 of 3 groups: lumbopelvic joint manipulation (grade V), side-lying lumbar midrange flexion and extension passive range of motion (grade II) for 1 minute, or prone extension on the elbows for 3 minutes. Main Outcome Measure(s): Quadriceps force and activation were measured using the burst superimposition technique during a seated isometric knee extension task. A 2-way repeated-measures analysis of variance was performed to compare changes in quadriceps force and activation among groups over time (before intervention and at 0, 20, 40, and 60 minutes after intervention). Results: We found no differences in quadriceps force output (F5,33,101,18 = 0.65, P = .67) or central activation ratio (F4.84,92.03 = 0.38, P= .86) values among groups after intervention. When groups were pooled, we found differences across time for quadriceps force (F2.66,101.18 = 5.03, P = .004) and activation (F2.42,92.03 = 3.85, P = .02). Quadriceps force was not different at 0 minutes after intervention (t40 = 1.68, P = .10), but it decreased at 20 (t40 = 2.16, P = .04), 40 (t40 = 2.87, P = .01) and 60 (t40 = 3.04, P = .004) minutes after intervention. All groups demonstrated decreased quadriceps activation at 0 minutes after intervention (t40 = 4.17, P &lt;.001), but subsequent measures were not different from preintervention levels (t40 range, 1.53–1.83, P &gt;.09). Conclusions: Interventions directed at the lumbopelvic region did not have immediate effects on quadriceps force output or activation. Muscle fatigue might have contributed to decreased force output and activation over 1 hour of testing.

Objective: The weakness of the quadriceps strength in patellofemoral pain syndrome (PFPS) is very evident. Therefore, quadriceps strengthening exercises are very important part of the rehabilitation program. Neuromuscular Electrical Stimulation (NMES) is considered one of the methods for increasing quadriceps muscle strength. To evaluate the effectiveness of combined NMES and strengthening exercises to improve the recovery of quadriceps strength and function in patients with PFPS. Methods: This study was planned as a randomized controlled pilot study. A total of 27 patients (mean age=38.9±10.8 years, range=20-60 years; 16 females) with PFPS were assessed and randomly assigned into 2 groups. Group I received a standard program (quadriceps strengthening, hip strengthening and hamstring stretching) and NMES combined with quadriceps strengthening exercises simultaneously. Group II received the same standard program without NMES. Both groups were enrolled 3 times per week for 40 minutes per day in 6 weeks. Patients were assessed at the baseline, 3 rd, 6th, and 12th weeks of treatment. Quadriceps strength was evaluated by isokinetic dynamometer. The range of motion at testing was set between 0 for extension to 90 for flexion. The test was performed at 60 degrees/sn and concentric maximum peak torque value was recorded. Kujala and Lysholm scores were used for functional assessments. The data were analyzed using the SPSS 20.0. Shapiro-Wilk test was used to assess the distribution of data. The changes in dependent variables before treatment, 3 rd, 6th, and 12th weeks were analyzed using a 2 by 4 mixed-model analysis of variance (ANOVA). Pairwise comparisons with paired t test were used to determine whether the Group I or Group II, has changed over time. An intention- to- treat analysis was performed to impute values for missing data. An alpha level of 0.05 was established. Results: The study was completed with 20 patients. Group I (n=10; mean age=39.4±8.5 years; 7 females) and group II (n=10; mean age=43.2±11.7 years; 5 females) had no differences in pre-operative measures (p>.05). There was significant improvements in within groups statistics of all parameters for both groups (p<.05). No differences in quadriceps strength, Kujala and Lysholm scores between groups were found at the different time points (F= 0.86; p = 0.12, F=0,001; p =0.97, F=0.12; p=0.73, respectively) Conclusion: NMES combined with quadriceps strengthening exercises has no additional effect on PFPS patients’ on muscle strength and function. When considering these results, we believe that there is no need to continue the study in progress. [Table: see text]

Background: Active rehabilitation has an important role in the management of patellofemoral pain syndrome (PFPS). Although some studies have shown the benefit of hip-muscle strengthening, the effect of combining hip-muscle stretching with strengthening has not yet been defined. Purpose: To evaluate the effect of combined strengthening of the hip external rotators and abductors and stretching of the hip internal rotators on pain and function in patients with PFPS. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: A total of 109 patients with PFPS (75 female and 34 male; mean age, 31.6 ± 10.8 years) were first randomly assigned to protocol A (n = 67) of the A-B arm (AB group; standard rehabilitation) or protocol B (n = 42) of the B-A arm (BA group; standard rehabilitation with strengthening of the hip external rotators and abductors and stretching of the hip internal rotators). Each protocol consisted of 3 sessions a week for 4 weeks. After a washout period, corresponding to a symptom-free period, rehabilitation programs were crossed over. A visual analog scale (VAS) evaluating perceived pain, the Functional Index Questionnaire (FIQ), and the Kujala score were administered at baseline, the end of each rehabilitation protocol, and 12 weeks after the completion of the second protocol for each group. Results: Until the final follow-up, VAS, FIQ, and Kujala scores were significantly improved in both the A-B and B-A arms ( P < .05 for all). Compared with protocol A, protocol B provided significant improvement in terms of pain and function in both the BA (VAS and Kujala; P < .001) and AB (VAS and Kujala; P < .001) groups. Conclusion: Combined strengthening of the hip abductors and external rotators with stretching of the hip internal rotators provided better outcomes, which were maintained for at least 12 weeks, in terms of pain and function in patients with PFPS.
