Abstract
OBJECTIVES The aim of this study was to evaluate whether a single treatment session of acupuncture, when applied in addition to standard treatment for acute low back pain (ALBP), reduces the time to recovery compared with standard treatment alone. DESIGN A multicentre, randomised, controlled trial. SETTING Conducted at 11 Norwegian general practitioners' (GPs') offices. PARTICIPANTS 171 adults aged 20-55 years seeking their GP for ALBP (≤14 days) between March 2014 and March 2017. Patients with secondary back pain and previous sick leave and acupuncture treatment was excluded. INTERVENTIONS The participants were randomised to either the control group (CG) or the acupuncture group (AG) by online software. The CG received standard treatment according to the Norwegian guidelines, while the AG received one session of Western medical acupuncture treatment in addition to standard treatment. The statistician was blinded to group status. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome was median days to recovery. Secondary outcomes were pain intensity, global improvement, back-specific functional status, sick leave, medication and adverse effects. RESULTS 185 participants were randomised, 95 in the CG and 90 in the AG. 14 participants did not receive the allocated intervention and 4 were excluded from the analysis. Thus, 167 participants were included in the analysis, 86 in the CG and 81 in the AG. The groups were similar according to baseline characteristics. The median time to recovery was 14 days for the CG and 9 days for the AG, HR 1.37 (95% CI 0.95 to 1.96), (p=0.089). No serious adverse effects were reported. CONCLUSIONS We did not find any statistically significant reduction in time-to-recovery after a single session of acupuncture for ALBP compared with standard care. TRIAL REGISTRATION NUMBER NCT01439412.

Abstract
Study Design Systematic review. Background Little is known about the effectiveness of acupuncture therapies for musculoskeletal disorders. Objective To assess the effectiveness and safety of acupuncture therapies for musculoskeletal disorders of the extremities. Methods We searched MEDLINE, Embase, CINAHL, PsycINFO, and Cochrane Central Register of Controlled Trials from 1990 to 2015 for randomized controlled trials, cohort studies, and case-control studies. Eligible studies were appraised with Scottish Intercollegiate Guidelines Network criteria. A best-evidence synthesis was performed to synthesize results from included studies with a low risk of bias. A sensitivity analysis was conducted to determine the impact of excluding studies with a high risk of bias. Results The search revealed 5180 articles; 15 were included (10 with a low risk of bias, 5 with a high risk of bias). The studies with a low risk of bias suggested that (1) traditional needle acupuncture was superior to oral steroids (1 RCT, n = 77) and may be superior to vitamin B1/B6 supplements (1 RCT, n = 64) for carpal tunnel syndrome (CTS), and was superior to exercise for Achilles tendinopathy (1 RCT, n = 64). Traditional needle acupuncture did not provide important benefit over placebo for upper extremity pain (1 RCT, n = 128), or no intervention for patellofemoral pain (1 RCT, n = 75), and was inconclusive for shoulder pain (2 RCTs, n = 849), suggesting no important benefit; (2) electroacupuncture may be superior to placebo for shoulder injuries (1 RCT, n = 130) and may not be superior to night splinting for persistent CTS (1 RCT, n = 78); and (3) dry needling may be superior to placebo for plantar fasciitis (1 RCT, n = 84). Sensitivity analysis suggests that including studies with a high risk of bias might have impacted the evidence synthesis in support of managing shoulder pain with traditional needle acupuncture, and that would suggest traditional needle acupuncture may be effective for lateral epicondylitis and piriformis syndrome. Conclusion Evidence for the effectiveness of acupuncture for musculoskeletal disorders of the extremities was inconsistent. Traditional needle acupuncture may be beneficial for CTS and Achilles tendinopathy, but not for nonspecific upper extremity pain and patellofemoral syndrome. Electroacupuncture may be effective for shoulder injuries and may show similar effectiveness to that of night wrist splinting for CTS. The effectiveness of dry needling for plantar fasciitis is equivocal. Level of Evidence Therapy, 1a-. J Orthop Sports Phys Ther 2016;46(6):409-429. Epub 26 Apr 2016. doi:10.2519/jospt.2016.6270.

Abstract
BACKGROUND Patellofemoral pain syndrome (PFPS) is a painful musculoskeletal condition, which is characterised by knee pain located in the anterior aspect (front) and retropatellar region (behind) of the knee joint. Various non-operative interventions are suggested for the treatment of this condition. Knee orthoses (knee braces, sleeves, straps or bandages) are worn over the knee and are thought to help reduce knee pain. They can be used in isolation or in addition to other treatments such as exercise or non-steroidal anti-inflammatory medications. OBJECTIVES To assess the effects (benefits and harms) of knee orthoses (knee braces, sleeves, straps or bandages) for treating PFPS. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (11 May 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2015 Issue 5), MEDLINE (1946 to 8 May 2015), EMBASE (1980 to 2015 Week 18), SPORTDiscus (1985 to 11 May 2015), AMED (1985 to 8 May 2015), CINAHL (1937 to 11 May 2015), PEDro (1929 to June 2015), trial registries and conference proceedings. SELECTION CRITERIA Randomised and quasi-randomised controlled clinical trials evaluating knee orthoses for treating people with PFPS. Our primary outcomes were pain and function. DATA COLLECTION AND ANALYSIS Two review authors independently assessed studies for eligibility, assessed study risk of bias and extracted data. We calculated mean differences (MD) or, where pooling data from different scales, standardised mean differences (SMD) with 95% confidence intervals (CI) for continuous outcomes and risk ratios (RR) with 95% CIs for binary outcomes. We pooled data using the fixed-effect model. MAIN RESULTS We included five trials (one of which was quasi-randomised) that reported results for 368 people who had PFPS. Participants were recruited from health clinics in three trials and were military recruits undergoing training in the other two trials. Although no trials recruited participants who were categorised as elite or professional athletes, military training does comprise intensive exercise regimens. All five trials were at high risk of bias, including performance bias reflecting the logistical problems in these trials of blinding of participants and care providers. As assessed using the GRADE approach, the available evidence for all reported outcomes is 'very low' quality. This means that we are very uncertain about the results.The trials covered three different types of comparison: knee orthosis and exercises versus exercises alone; one type of orthosis versus another; and knee orthosis versus exercises. No trials assessed the mode of knee orthosis use, such as whether the orthosis was worn all day or only during physical activity. Two trials had two groups; two trials had three groups; and one trial had four groups.All five trials compared a knee orthosis (knee sleeve, knee brace, or patellar strap) versus a 'no treatment' control group, with all participants receiving exercises, either through a military training programme or a home-based exercise programme. There is very low quality evidence of no clinically important differences between the two groups in short-term (2 to 12 weeks follow-up) knee pain based on the visual analogue scale (0 to 10 points; higher scores mean worse pain): MD -0.46 favouring knee orthoses, 95% CI -1.16 to 0.24; P = 0.19; 234 participants, 3 trials). A similar lack of clinically important difference was found for knee function (183 participants, 2 trials). None of the trials reported on quality of life measures, resource use or participant satisfaction. Although two trials reported on the impact on sporting or occupational participation, one trial (35 participants) did not provide data split by treatment group on the resumption of sport activity and the other reported only on abandonment of military training due to knee pain (both cases were allocated a knee orthosis). One trial (59 participants, 84 affected knees) recording only adverse events in the two knee orthoses (both were knee sleeves) groups, reported 16 knees (36% of 44 knees) had discomfort or skin abrasion.Three trials provided very low quality evidence on single comparisons of different types of knee orthoses: a knee brace versus a knee sleeve (63 participants), a patella strap with a knee sleeve (31 participants), and a knee sleeve with a patellar ring versus a knee sleeve only (44 knees). None of three trials found an important difference between the two types of knee orthosis in pain. One trial found no clinically important difference in function between a knee brace and a knee sleeve. None of the three trials reported on quality of life, resource use or participant satisfaction. One trial comparing a patella strap with a knee sleeve reported that both participants quitting military training due to knee pain were allocated a knee sleeve. One poorly reported trial found three times as many knees with adverse effects (discomfort or skin abrasion) in those given knee sleeves with a patella ring than those given knee sleeves only.One trial compared a knee orthosis (knee brace) with exercise (66 participants). It found very low quality evidence of no clinically important difference between the two intervention groups in pain or knee function. The trial did not report on quality of life, impact on sporting or occupational participation, resource use, participant satisfaction or complications. AUTHORS' CONCLUSIONS Overall, this review has found a lack of evidence to inform on the use of knee orthoses for treating PFPS. There is, however, very low quality evidence from clinically heterogeneous trials using different types of knee orthoses (knee brace, sleeve and strap) that using a knee orthosis did not reduce knee pain or improve knee function in the short term (under three months) in adults who were also undergoing an exercise programme for treating PFPS. This points to the need for good-quality clinically-relevant research to inform on the use of commonly-available knee orthoses for treating PFPS.

Abstract
In this review the evidence for the management of patients with patellofemoral disorders is presented confined to anterior knee pain and patellar dislocation (excluding patellofemoral arthritis). Patients present along a spectrum of these two problems and are best managed with both problems considered. The key to managing these patients is by improving muscle function, the patient losing weight (if overweight), and judicious use of analgesics if pain is an important feature. Hypermobility syndrome should always be looked for since this is a prognostic indicator for a poor operative outcome. Operations should be reserved for those with correctable anatomical abnormalities that have failed conservative therapy. The current dominant operation is a medial patellofemoral ligament reconstruction.

Abstract
Objective The authors asked the following research questions: will an anterior knee infusion model induce constant pain? will perceived pain alter motoneuron pool (MNP) excitability? and will treatments alter perceived pain and/or MNP excitability? Methods Thirty-six neurologically healthy volunteers participated in this randomised controlled laboratory study. To induce anterior knee pain (AKP), 5% hypertonic saline (0.12 ml/min with a total volume of 8.5 ml over 70 min) was injected into the infrapatellar fat pad of the dominant leg. One of four 30-min treatments was randomly assigned to each subject after pain was induced (acupuncture, cryotherapy, sham cryotherapy and no treatment). Five acupuncture needles (SP9, SP10, ST36, GB34 and an ah shi point) were inserted to a depth of 1 cm. Vastus medialis (VM) maximum Hoffmann reflexes normalised by maximum motor response were recorded from each subject at baseline, 20 min post-injection, 50 min post-injection and 70 min post-injection. To record pain perception, a visual analogue scale was used every 5 min after injection. Results An anterior knee infusion pain model increased perceived pain (p<0.0001). No change was found in VM MNP excitability among the four treatments (p<0.19) or at any of the time intervals (p<0.52). Cryotherapy reduced perceived pain compared with acupuncture (p=0.0003) and sham treatment (p=0.0002). Conclusions A pain model may be used in other neurophysiological intervention studies related to AKP. AKP alone may not directly alter quadriceps activation. None of the treatments altered VM MNP excitability. Cryotherapy reduced pain while a single session of acupuncture and sham treatments did not.

Abstract
Excision of the eroded lateral patellar facet has been suggested as an acceptable treatment for short-term pain reduction in patients with isolated patellofemoral osteoarthritis. The outcome of this procedure at long-term is however not known. We therefore reviewed the results of 155 consecutive patients (168 knees) treated at our institution with lateral facetectomy at an average follow up of 10.9 years (± 6.9 years SD). During follow up 62 knees (36.9%) had failed and were revised to either TKA (60 knees), patellofemoral arthroplasty (one case) or total patellectomy (one case). Average time to reoperation in the failure group was 8.0 years (± 6.2 years SD). Kaplan-Meier survival rates with reoperation as endpoint were 85% at 5 years, 67.2% at 10 years, and 46.7% at 20 years respectively. At final follow up 79 (74.5%) of the knees that had not been re-operated were rated as either good or fair, which corresponds to 47% of the original group. Our study therefore demonstrates that a satisfactory outcome after lateral patellar facetectomy for isolated patellofemoral osteoarthritis can be expected in approximately half of the cases at 10 year follow up.

Abstract
AIMS AND OBJECTIVES To examine and compare the effects of acupressure on the perceived health-related quality of life of the participants with bronchiectasis. BACKGROUND In an attempt to offer comfort, pain control and symptom management, nursing is becoming increasingly involved in offering complementary-alternative medicine as part of its caring-healing focus in comprehensive patient care. Acupressure is one such modality that is being increasingly used by both medical and nursing professionals. While acupressure has been reported to have beneficial effects in patients with respiratory disease, the benefits to bronchiectasis patients have remained uncertain. DESIGN A randomized, partially blinded study consisting of three groups. METHODS Thirty-five out-patients of both genders, aged 59.46 SD 11.52 years, who were suffering from bronchiectasis, were randomly split into one of three groups: standard care with supplemental acupressure for eight weeks (11 participants); standard care with supplemental sham acupressure for eight weeks (11 participants); and standard care alone (13 participants). Outcomes were determined by changes in daily sputum amounts, sputum self-assessment, six-minute walking distance, breathing difficulty (measured on the dyspnea visual analogue scale) and health-related quality of life (measured by the Saint George Respiratory Questionnaire). RESULTS The sputum self-assessment score improved over time for the sham acupressure participants (P = 0.03), when compared with the controls. For acupressure participants, the Saint George respiratory questionnaire activity component scores also improved over time, compared with controls (P = 0.01) after adjustment for covariates (treatment, time, age, sex and baseline values). Other variables did not differ between the standard care alone group and the other two groups. CONCLUSIONS Eight weeks of self-administered acupressure could be useful in reducing the effects of bronchiectasis on a patient's daily activities. RELEVANCE TO CLINICAL PRACTICE Acupressure may be regarded as a viable nursing intervention.

Abstract
STUDY DESIGN Randomized controlled trial, pretest-posttest design. OBJECTIVES To compare the efficacy of non-weight-bearing single-joint quadriceps exercise (SJNWBE) versus weight-bearing multiple-joint quadriceps exercise (MJWBE) for individuals with patellofemoral pain syndrome (PFPS). BACKGROUND PFPS is a common ailment of the knee. Both weight-bearing and non-weight-bearing exercises are considered appropriate for strengthening the quadriceps, a key element in the treatment of this condition. METHODS AND MEASURES Forty-five male subjects with PFPS between 18 and 35 years of age were randomized into 1 of 3 groups. Group 1 (SJNWBE) performed knee extension exercises, group 2 (MJWBE) performed seated leg press exercises, and group 3 (control group) received no treatment. Subjective symptoms, knee extensor muscle strength, and functional performance were evaluated at the time of the initial examination and at the end of the 6-week treatment period. RESULTS Individuals in both exercise groups demonstrated a statistically significant decrease in pain and an increase in muscle strength and functional performance, as compared to the control group (P<.05). All measures showed no significant differences in outcome between the 2 exercise groups (P>.05). CONCLUSION This study demonstrates that both weight-bearing and non-weight-bearing quadriceps exercises can significantly improve subjective and clinical outcomes in patients with PFPS.

Abstract
BACKGROUND Anterior knee pain, diagnosed as Patellofemoral Pain Syndrome (PFPS), is one of the most common musculoskeletal problems found in adolescents and young adults. There is no consensus in medical literature concerning the aetiology of the PFPS. AIMS To assess by means of Quantitative Sensory Testing (QST) whether patients suffering from long-lasting unilateral PFPS demonstrate somatosensory dysfunction related to afferent fibres from the local pain area. METHODS A descriptive non-experimental study with two independent samples, consisting of 25 men and women between 18 and 44 years of age with unilateral PFPS, and a comparable group of 23 healthy subjects. Somedic Thermotest apparatus was used to assess thresholds of thermal perception, and of heat and cold pain thresholds. Von Frey filaments were used to detect tactile sensitivity. Furthermore, quality and intensity of knee pain, symptoms and signs from a clinical neurological examination were recorded. RESULTS Decreased sensitivity to tactile stimulation, when tested with von Frey filaments, was demonstrated on both the painful and pain-free knee in subjects with PFPS, compared to the mean between the knees of the control group (p< or =0.001). The mean detection threshold for warmth was increased by 1.9 degrees C (p< or =0.01) in the painful knee, and 1.4 degrees C (p< or =0.01) in the non-painful knee in the PFPS group, compared to the mean of the healthy control group. The mean detection threshold for cold was increased by 1.6 degrees C (p< or =0.01) in the painful knee of the PFPS group, compared to the control group. These findings were supported by clinical sensory tests. No significant differences of mean thermal pain thresholds between the PFPS group and controls were found, and there were no significant differences in mean detection thresholds for warmth, cold or thermal pain thresholds between the painful and the non-painful knees in the PFPS group. CONCLUSION This study demonstrated an abnormal sensory function in the painful and non-painful knee in some individuals with long lasting unilateral Patellofemoral Pain Syndrome using Quantitative Sensory Testing supported by clinical neurological examinations. A dysfunction of the peripheral and/or the central nervous system may cause neuropathic pain in some subjects with PFPS.

BACKGROUND Psychological variables and those describing self-perceived health status have been given little focus in PFPS research. METHODS AND MEASURES One group of 25 men and women between 19 and 44 years of age with unilateral long lasting PFPS, and a control group (n = 23) of healthy subjects (age range, 18-44 years) participated in the study. Knee function was assessed with the use of the Cincinnati Knee Rating System (CKRS) and the triple jump test, and knee pain was measured by a visual analogue scale (VAS). Self-perceived health and mental distress were assessed with the Coop-Wonca Chart and the Hopkins Symptoms Checklist-25 (HSCL-25) questionnaire. RESULTS The mean (+/- SD) score on the Coop-Wonca Chart was 2.02 +/- 0.73 in the PFPS group, compared to 1.20 +/- 0.53 in the controls (P < .001). HSCL-25 mean (+/- SD) scores were 1.46 +/- 0.47 and 1.08 +/- 0.18 (P < .001) for the PFPS and the control group, respectively. When analyzed with correlation statistics, CKRS and VAS scores were found to correlate to those of the Coop-Wonca Chart and HSCL-25 scores. CONCLUSION Levels of mental distress were higher in the group with PFPS than in the control group, while levels of self-perceived health were lower. Our data indicate that the levels of knee pain and knee function correlate closely to the degree of mental distress and self-perceived health in individuals with PFPS.

Abstract
Patellofemoral pain syndrome is common among athletes and non-athletes. It results from an imbalance of forces acting on the patellofemoral joint, which leads to increased strain on the peripatellar soft tissues, increased patellofemoral joint stress, or both. The most important risk factors are overuse, quadriceps weakness, and soft-tissue tightness. In most cases, the etiology is multifactorial. A careful history and targeted physical examination will confirm the diagnosis and determine the most appropriate treatment. A physical therapy program that employs quadriceps strengthening, manual stretching of the lateral patellar soft-tissue structures, patellar taping, and biofeedback is successful in the majority of cases. Surgery maybe required for the few patients who do not respond to nonoperative management.

Abstract
OBJECTIVE To examine the test-retest reliability, validity, and responsiveness of several outcome measures in the treatment of patellofemoral pain. DESIGN Evaluation of the clinimetric properties of individual outcome measures for patellofemoral pain treatment, using data collected from a previously published randomized controlled trial (RCT). SETTING General community and private practice. PARTICIPANTS The data from 71 persons enrolled in an RCT of a conservative intervention for patellofemoral pain were used to evaluate the measures' validity and responsiveness. A subset of this cohort (n=20) was used to assess reliability. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Three 10-cm visual analog scales (VASs) for usual pain (VAS-U), worst pain (VAS-W), and pain on 6 aggravating activities (walking, running, squatting, sitting, ascending and descending stairs) (VAS-activity); the Functional Index Questionnaire (FIQ); the Anterior Knee Pain Scale (AKPS); and the global rating of change. RESULTS The test-retest reliability ranged from poor (intraclass correlation coefficient [ICC]=.49) to good (ICC=.83), and the measures correlated moderately with each other (r range,.56-.72). Median change scores differed significantly between improved and unimproved persons for all measures. The effect sizes for VAS-U (.79), VAS-W (.88), and the AKPS (.98) were large, indicating greater responsiveness than the FIQ (.37) and VAS-activity (.66). Similarly, the AKPS and VAS-W were the most efficient measures for detecting a treatment effect when compared with a reference measure (VAS-U, which was assigned a value of 1). The minimal difference that patients or clinicians consider clinically important for the AKPS is 10 (out of 100) points and for the VAS it is 2cm (out of 10cm). CONCLUSIONS The AKPS and VAS for usual or worst pain are reliable, valid, and responsive and are therefore recommended for future clinical trials or clinical practice in assessing treatment outcome in persons with patellofemoral pain.

Abstract
Abstract
Background and Purpose. In patients with patellofemoral pain syndrome (PFPS), the authors determined which aspects of the examination could be used to identify those patients most likely to respond to off-the-shelf foot orthoses and instruction in activity modification. Participants and Methods. Fifty participants were enrolled in the study, and data for 5 individuals were excluded from analysis. Thirty-four men and 11 women completed the study. Participants were given foot orthoses and instructed in activity modification for 3 weeks. A 50% reduction in pain was considered a success. Likelihood ratios (LRs) were computed to determine which examination findings were most predictive of success. Results. The best predictors of improvement were forefoot valgus alignment of ≥2 degrees (+LR=4.0, 95% confidence interval [CI]=0.7–21.9), great toe extension of ≤78 degrees (+LR=4.0, 95% CI=0.7–21.9), and navicular drop of ≤3 mm (+LR=2.4, 95% CI=1.3–4.3). Discussion and Conclusion. The results suggest that patients with PFPS who have forefoot valgus alignment of ≥2 degrees, passive great toe extension of ≤78 degrees, or navicular drop of ≤3 mm are most likely to respond favorably to initial intervention with an off-the-shelf foot orthosis and instruction in activity modification.

Abstract
Nurses have used complementary therapies for many years to relieve anxiety, promote comfort, and reduce or alleviate pain. The therapies described in this article are examples of the many therapies available for nurses to consider when planning care for patients with chronic pain. The increasing body of scientific knowledge is providing more guidance about the efficacy of specific therapies. As with all interventions, ongoing evaluation about the effectiveness of a therapy for each patient is an important component of quality nursing care. Complementary therapies provide an avenue for nurses to be autonomous in furthering the relief of chronic pain, as many of these therapies fall within the domain of nursing. Incorporating selected therapies into the plan of care provides multiple opportunities for nurses to demonstrate caring, a premier characteristic of nursing. A number of the complementary therapies, such as journaling, hand massage, and imagery, can be taught to patients and their families, thus promoting self-care. Anecdotal evidence and findings from numerous smaller studies provide some support for the use of many complementary therapies to manage chronic pain or their use as adjuncts in the treatment regimen. Still, the nurse must weigh the risks and benefits before suggesting a therapy to a patient. Evaluating the effectiveness of the complementary therapy to promote comfort in patients with chronic pain is essential. Obtaining this information is not only critical to the care of a particular patient, but these data will assist nurses in learning more about specific therapies. Most importantly, nurses need to pursue research to further the scientific basis for many of the complementary therapies.

Abstract
STUDY DESIGN Systematic review of the literature. OBJECTIVES To develop a grading scale to judge the quality of randomized clinical trials (RCTs) and conduct a systematic review of the published RCTs that assess nonoperative treatments for patellofemoral pain syndrome (PFPS). BACKGROUND Systematic reviews of the quality and usefulness of clinical trials allow for efficient synthesis and dissemination of the literature, which should facilitate clinicians' efforts to incorporate principles of evidence-based practice in the clinical decision-making process. METHODS AND MEASURES Using a scale based on criteria in the Cochrane Collaboration Handbook, we sought to critically appraise the methodology used in RCTs related to the nonoperative management of PFPS, synthesize and interpret our results, and report our findings in a user-friendly fashion. A scale to assess the methodological quality of trials was designed and pilot tested for its content and reliability. Published RCTs identified during a literature search were then selected and rated by 6 raters. We used predefined cutoff scores to identify specific weaknesses in the clinical research process that need to be improved in future clinical trials. RESULTS The quality scale we developed was demonstrated to be sufficiently reliable to warrant interpretation of the reviewers' findings. The percentage of trials that met a minimum level of quality for each specific criterion ranged from a low of 25% for the adequacy of the description of the randomization procedure to a high of 95% for the description and standardization of the intervention. CONCLUSIONS Based on the results of trials exhibiting a sufficient level of quality, treatments that were effective in decreasing pain and improving function in patients with PFPS were acupuncture, quadriceps strengthening, the use of a resistive brace, and the combination of exercises with patellar taping and biofeedback. The use of soft foot orthotics in patients with excessive foot pronation appeared useful in decreasing pain. In addition, at a short-term follow-up, patients who received exercise programs were discharged earlier from physical therapy. Unfortunately, most RCTs reviewed contained qualitative flaws that bring the validity of the results into question, thus diminishing the ability to generalize the results to clinical practice. These flaws were primarily in the areas of randomization procedures, duration of follow-up, control of cointerventions, assurance of blinding, accountability and proper analysis of dropouts, number of subjects, and the relevance of outcomes. Also, given the limited number of high-quality clinical trials, recommendations about supporting or refuting specific treatment approaches may be premature and can only be made with caution.

Abstract
BACKGROUND Although physical therapy forms the mainstay of nonoperative management for patellofemoral pain, its efficacy has not been established. HYPOTHESIS Significantly more pain relief will be achieved from a 6-week regimen of physical therapy than from placebo treatment. STUDY DESIGN Multicenter, randomized, double-blinded, placebo-controlled trial. METHODS Seventy-one subjects, 40 years of age or younger with patellofemoral pain of 1 month or longer, were randomly allocated to a physical therapy or placebo group. A standardized treatment program consisted of six treatment sessions, once weekly. Physical therapy included quadriceps muscle retraining, patellofemoral joint mobilization, and patellar taping, and daily home exercises. The placebo treatment consisted of sham ultrasound, light application of a nontherapeutic gel, and placebo taping. RESULTS Sixty-seven participants completed the trial. The physical therapy group (N = 33) demonstrated significantly greater reduction in the scores for average pain, worst pain, and disability than did the placebo group (N = 34). CONCLUSIONS A six-treatment, 6-week physical therapy regimen is efficacious for alleviation of patellofemoral pain.

Abstract
OBJECTIVE Physical interventions (nonpharmacological and nonsurgical) are the mainstay of treatment for patellofemoral pain syndrome (PFPS). Physiotherapy is the most common of all physical interventions and includes specific vastus medialis obliquus or general quadriceps strengthening and/or realignment procedures (tape, brace, stretching). These treatments appear to be based on sound theoretical rationale and have attained widespread acceptance, but evidence for the efficacy of these interventions is not well established. This review will present the available evidence for physical interventions for PFPS. DATA SOURCES Computerized bibliographic databases (MEDLINE, Current Contents, CINAHL) were searched, including the keywords "patellofemoral," "patella," and "anterior knee pain," combined with "treatment," "rehabilitation," and limited to clinical trials through October 2000. STUDY SELECTION The critical eligibility criteria used for inclusion were that the study be a controlled trial, that outcome assessments were adequately described, and that the treatment was a nonpharmacological, nonsurgical physical intervention. RESULTS Of the 89 potentially relevant titles, 16 studies were reviewed and none of these fulfilled all of the requirements for a randomized, controlled trial. Physiotherapy interventions were evaluated in eight trials, and the remaining eight trials examined different physical interventions. Significant reductions in PFPS symptoms were found with a corrective foot orthosis and a progressive resistance brace, but there is no evidence to support the use of patellofemoral orthoses, acupuncture, low-level laser, chiropractic patellar mobilization, or patellar taping. Overall the physiotherapy interventions had significant beneficial effects but these interventions were not compared with a placebo control. There is inconclusive evidence to support the superiority of one physiotherapy intervention compared with others. CONCLUSIONS The evidence to support the use of physical interventions in the management of PFPS is limited. There appears to be a consistent improvement in short-term pain and function due to physiotherapy treatment, but comparison with a placebo group is required to determine efficacy, and further trials are warranted for the other interventions.
