Abstract
PURPOSE The aim of this umbrella review is to determine the effectiveness of LLLT in the treatment of LET and to provide recommendations based on this evidence. METHODS A comprehensive and systematic review was undertaken using Medline, EBSCO and EMBASE. Systematic reviews or meta-analysis were included if they compared Laser with at least one of the following: (i) placebo, (ii) no treatment, (iii) another treatment, conservative (physical therapy intervention or medical) or operative of LET. Principal outcomes included the assessment of short and long-term effect on functional status, pain, grip strength (pain-free or maximum) and a global measure (overall improvement). RESULTS Seven papers met the inclusion criteria for the umbrella review, Five papers were of moderate and two of low methodological quality. All reviews reported benefits associated with laser therapy Vs other intervention or placebo, however the significance of the identified benefits differed between studies and reviews. No review reported negative effects of laser therapy or harm to patients. All reviews noted significant variance between included studies with 2 reviews citing statistically significant heterogeneity. It is essential to consider this in the interpretation of these data. CONCLUSION This umbrella review found poor results for the effectiveness of LLLT in the management of LET. Therefore, further research with well-designed RCTs is required to provide meaningful evidence on the effectiveness (absolute and relative) of LLLT for the management of LET.

Abstract
Elbow tendinopathy accounts for the majority of elbow pathology in patients presenting to upper extremity and sports medicine surgeons. With increased participation in overhead sports in an aging population, the incidence of elbow injuries has risen. A comprehensive knowledge of elbow anatomy and biomechanical function of the elbow complex is prerequisite in the assessment of patients with elbow injuries; however, a thorough understanding of alternative and confounding pathologies is essential for accurate diagnosis. Because tendinopathy, tendonitis, and tendon tears have an anatomic basis for their pathology, a targeted history and meticulous physical examination often yields an accurate clinical diagnosis. The importance of physical examination and provocative examination maneuvers must be stressed in a technologically advanced era where clinical diagnosis is too commonly attained solely by advanced imaging modalities. A revived dedication to the physical examination may enhance our ability to correctly diagnose various pathologies about the elbow. Early and accurate clinical diagnosis is the first step in the proper initiation of treatment modalities and improvement in overall patient outcome.

Abstract
The value of low-level laser therapy (LLLT) as a therapy for painful tennis elbow is dubious since evidence for its efficacy is conflicting. This report presents the results of a randomized, double-blind, controlled study on patients with tennis elbow (n = 29) using a gallium aluminium arsenide laser. Two different methods of assessing pain, visual analogue scores and a Marcy Wedge Pro® exerciser, were used. No significant differences were found between the treatment and placebo groups. This suggests that LLLT at the dosage and duratiion used in this study is without benefit in the short-term management of painful tennis elbow.

Abstract
The purpose of the study was to determine the effectiveness of a custom-made below elbow lateral counterforce splint along with standard physiotherapy compared with physiotherapy alone, for the treatment of lateral epicondylitis. It was hypothesized that the recovery from lateral epicondylitis is greater following four weeks of standard physiotherapy and the use of the splint, than following four weeks of standard physiotherapy alone. The experimental group (with the splint and physiotherapy) demonstrated a significant improvement in pain (p = 0.05) and maximum grip strength (p = 0.025) of the affected arm compared to the control group. The experimental group showed a greater improvement in function approaching but not reaching significance. The results indicate that this custom-made splint is of value in facilitating the recovery from lateral epicondylitis.

Abstract
BACKGROUND Lateral elbow tendinopathy (LET) is a common complaint causing characteristic pain in the lateral elbow and upper forearm, and tenderness of the forearm extensor muscles. It is thought to be an overuse injury and can have a major impact on the patient's social and professional life. The condition is challenging to treat and prone to recurrent episodes. The average duration of a typical episode ranges from 6 to 24 months, with most (89%) reporting recovery by 1 year. OBJECTIVES This systematic review aims to summarise the evidence concerning the clinical effectiveness and cost-effectiveness of conservative interventions for LET. DATA SOURCES A comprehensive search was conducted from database inception to 2012 in a range of databases including MEDLINE, EMBASE and Cochrane Databases. METHODS AND OUTCOMES We conducted an overview of systematic reviews to summarise the current evidence concerning the clinical effectiveness and a systematic review for the cost-effectiveness of conservative interventions for LET. We identified additional randomised controlled trials (RCTs) that could contribute further evidence to existing systematic reviews. We searched MEDLINE, EMBASE, Allied and Complementary Medicine Database, Cumulative Index to Nursing and Allied Health Literature, Web of Science, The Cochrane Library and other important databases from inception to January 2013. RESULTS A total of 29 systematic reviews published since 2003 matched our inclusion criteria. These were quality appraised using the Assessment of Multiple Systematic Reviews (AMSTAR) checklist; five were considered high quality and evaluated using a Grading of Recommendations, Assessment, Development and Evaluation approach. A total of 36 RCTs were identified that were not included in a systematic review and 29 RCTs were identified that had only been evaluated in an included systematic review of intermediate/low quality. These were then mapped to existing systematic reviews where further evidence could provide updates. Two economic evaluations were identified. LIMITATIONS The summary of findings from the review was based only on high-quality evidence (scoring of > 5 AMSTAR). Other limitations were that identified RCTs were not quality appraised and dichotomous outcomes were also not considered. Economic evaluations took effectiveness estimates from trials that had small sample sizes leading to uncertainty surrounding the effect sizes reported. This, in turn, led to uncertainty of the reported cost-effectiveness and, as such, no robust recommendations could be made in this respect. CONCLUSIONS Clinical effectiveness evidence from the high-quality systematic reviews identified in this overview continues to suggest uncertainty as to the effectiveness of many conservative interventions for the treatment of LET. Although new RCT evidence has been identified with either placebo or active controls, there is uncertainty as to the size of effects reported within them because of the small sample size. Conclusions regarding cost-effectiveness are also unclear. We consider that, although updated or new systematic reviews may also be of value, the primary focus of future work should be on conducting large-scale, good-quality clinical trials using a core set of outcome measures (for defined time points) and appropriate follow-up. Subgroup analysis of existing RCT data may be beneficial to ascertain whether or not certain patient groups are more likely to respond to treatments.

Abstract
BACKGROUND Lateral epicondylitis is a painful tendinopathy for which several nonsurgical treatment strategies are used. Superiority of these nonsurgical treatments over nontreatment has not been definitively established. QUESTIONS/PURPOSES We asked whether nonsurgical treatment of lateral epicondylitis compared with observation only or placebo provides (1) better overall improvement, (2) less need for escape interventions, (3) better outcome scores, and (4) improved grip strength at intermediate- to long-term followup. METHODS The English-language literature was searched using PubMed and the Cochrane Central Register of Controlled Trials. Randomized-controlled trials (RCTs) comparing any form of nonsurgical treatment with either observation only or placebo at followup of at least 6 months were included. Nonsurgical treatments included injections (corticosteroid, platelet-rich plasma, autologous blood, sodium hyaluronate, or glycosaminoglycan polysulfate), physiotherapy, shock wave therapy, laser, ultrasound, corticosteroid iontophoresis, topical glyceryl trinitrate, or oral naproxen. Methodologic quality was assessed with the Consolidated Standards of Reporting Trials (CONSORT) checklist, and 22 RCTs containing 2280 patients were included. Pooled analyses were performed to evaluate overall improvement; requirement for escape interventions (treatment of any kind, outside consultation, and surgery); outcome scores (Patient-Rated Tennis Elbow Evaluation [PRTEE]; DASH; Pain-Free Function Index [PFFI]; EuroQoL [EQ]-5D; and overall function); and maximum and pain-free grip strength. Sensitivity analyses were performed using only trials of excellent or good quality. Heterogeneity analyses were performed, and funnel plots were constructed to assess for publication bias. RESULTS Nonsurgical treatment was not favored over nontreatment based on overall improvement (risk ratio [RR] = 1.05 [0.96-1.15]; p = 0.32), need for escape treatment (RR = 1.50 [0.84-2.70]; p = 0.17), PRTEE scores (mean difference [MD] = 1.47, [0.68-2.26]; p < 0.001), DASH scores (MD = -2.69, [-15.80 to 10.42]; p = 0.69), PFFI scores (standardized mean difference [SMD] = 0.25, [-0.32 to 0.81]; p = 0.39), overall function using change-from-baseline data (SMD = 0.11, [-0.14 to 0.36]; p = 0.37) and final data (SMD = -0.16, [-0.79 to 0.47]; p = 0.61), EQ-5D scores (SMD = 0.08, [-0.52 to 0.67]; p = 0.80), maximum grip strength using change-from-baseline data (SMD = 0.12, [-0.11 to 0.35]; p = 0.31) and final data (SMD = 4.37, [-0.65 to 9.38]; p = 0.09), and pain-free grip strength using change-from-baseline data (SMD = -0.20, [-0.84 to 0.43]; p = 0.53) and final data (SMD = -0.03, [-0.61 to 0.54]; p = 0.91). CONCLUSIONS Pooled data from RCTs indicate a lack of intermediate- to long-term clinical benefit after nonsurgical treatment of lateral epicondylitis compared with observation only or placebo.

Abstract
OBJECTIVES To assess the clinical effectiveness of Low Level Laser Therapy (LLLT) in the treatment of tendinopathy. Secondary objectives were to determine the relevance of irradiation parameters to outcomes, and the validity of current dosage recommendations for the treatment of tendinopathy. BACKGROUND LLLT is proposed as a possible treatment for tendon injuries. However, the clinical effectiveness of this modality remains controversial, with limited agreement on the most efficacious dosage and parameter choices. METHOD The following databases were searched from inception to 1(st) August 2008: MEDLINE, PubMed, CINAHL, AMED, EMBASE, All EBM reviews, PEDro (Physiotherapy Evidence Database), SCOPUS. Controlled clinical trials evaluating LLLT as a primary intervention for any tendinopathy were included in the review. Methodological quality was classified as: high (> or =6 out of 10 on the PEDro scale) or low (<6) to grade the strength of evidence. Accuracy and clinical appropriateness of treatment parameters were assessed using established recommendations and guidelines. RESULTS Twenty-five controlled clinical trials met the inclusion criteria. There were conflicting findings from multiple trials: 12 showed positive effects and 13 were inconclusive or showed no effect. Dosages used in the 12 positive studies would support the existence of an effective dosage window that closely resembled current recommended guidelines. In two instances where pooling of data was possible, LLLT showed a positive effect size; in studies of lateral epicondylitis that scored > or =6 on the PEDro scale, participants' grip strength was 9.59 kg higher than that of the control group; for participants with Achilles tendinopathy, the effect was 13.6 mm less pain on a 100 mm visual analogue scale. CONCLUSION LLLT can potentially be effective in treating tendinopathy when recommended dosages are used. The 12 positive studies provide strong evidence that positive outcomes are associated with the use of current dosage recommendations for the treatment of tendinopathy.

Abstract
Background Recent reviews have indicated that low level level laser therapy (LLLT) is ineffective in lateral elbow tendinopathy (LET) without assessing validity of treatment procedures and doses or the influence of prior steroid injections. Methods Systematic review with meta-analysis, with primary outcome measures of pain relief and/or global improvement and subgroup analyses of methodological quality, wavelengths and treatment procedures. Results 18 randomised placebo-controlled trials (RCTs) were identified with 13 RCTs (730 patients) meeting the criteria for meta-analysis. 12 RCTs satisfied half or more of the methodological criteria. Publication bias was detected by Egger's graphical test, which showed a negative direction of bias. Ten of the trials included patients with poor prognosis caused by failed steroid injections or other treatment failures, or long symptom duration or severe baseline pain. The weighted mean difference (WMD) for pain relief was 10.2 mm [95% CI: 3.0 to 17.5] and the RR for global improvement was 1.36 [1.16 to 1.60]. Trials which targeted acupuncture points reported negative results, as did trials with wavelengths 820, 830 and 1064 nm. In a subgroup of five trials with 904 nm lasers and one trial with 632 nm wavelength where the lateral elbow tendon insertions were directly irradiated, WMD for pain relief was 17.2 mm [95% CI: 8.5 to 25.9] and 14.0 mm [95% CI: 7.4 to 20.6] respectively, while RR for global pain improvement was only reported for 904 nm at 1.53 [95% CI: 1.28 to 1.83]. LLLT doses in this subgroup ranged between 0.5 and 7.2 Joules. Secondary outcome measures of painfree grip strength, pain pressure threshold, sick leave and follow-up data from 3 to 8 weeks after the end of treatment, showed consistently significant results in favour of the same LLLT subgroup (p < 0.02). No serious side-effects were reported. Conclusion LLLT administered with optimal doses of 904 nm and possibly 632 nm wavelengths directly to the lateral elbow tendon insertions, seem to offer short-term pain relief and less disability in LET, both alone and in conjunction with an exercise regimen. This finding contradicts the conclusions of previous reviews which failed to assess treatment procedures, wavelengths and optimal doses.

Abstract
Symptoms of lateral epicondylitis (LE) are attributed to degenerative changes and inflammatory reactions in the common extensor tendon induced by microscopic tears in the tissue after repetitive or overload functions of the wrist and hand extensor muscles. Conventional treatments, provided on the premise of inflammatory basis of LE, have shown 39-80% failure rate. An alternative approach suggests that symptoms of LE could be due to active tender points developed in the origin of hand and wrist extensor muscles after overuse or repetitive movements. Oscillating-energy Manual Therapy (OEMT), also known as V-spread, is a craniosacral manual technique that has been clinically used for treating tender points over the suture lines in the skull. Considering symptoms of LE may result from active tender points, the purpose of this study was to investigate the effect of OEMT on pain, grip strength, and functional abilities of subjects with chronic LE. Twenty-three subjects with chronic LE (>3mo) between ages of 24 and 72 years participated in this study. Before their participation, all subjects were screened to rule out cervical and other pathologies that could possibly contribute to their lateral elbow pain. Subjects who met the inclusion criteria were randomized into treatment and placebo treatment groups by a second (treating) therapist. Subjects were blinded to their group assignment. Subjects in the treatment group received OEMT for six sessions. During each treatment session, first a tender point was located through palpation. After proper hand placement, the therapist focused the direction of the oscillating energy on the localized tender point. Subjects in the placebo group underwent the same procedure, but the direction of the oscillating energy was directed to an area above or below the tender points, not covering the affected area. Jamar Dynamometer, Patient Specific Functional Scale (PSFS), and Numeric Rating Scale (NRS) were used to measure grip strength, functional status, and pain intensity and limited activity due to pain, respectively. The screening therapist who was blinded to the subjects' group assignment performed pretest, posttest, and six-month follow-up measurements. Subjects in the treatment group showed both clinically and statistically significant improvement in grip strength (p=0.03), pain intensity (p=0.006), function (p=0.003), and limited activity due to pain (p=0.025) compared with those in the placebo group. Follow-up data, collected after six months, showed no significant difference between posttest and follow-up measurements in functional activity (p=0.35), pain intensity (p=0.72), and activity limitation due to pain (p=0.34). Of all the subjects contacted for follow-up assessment, 91% maintained improved function and 73% remained pain free for at least six months. OEMT seems to be a viable, effective, and efficient alternative treatment for LE.

Abstract
BACKGROUND Eccentric exercises (EEs) are recommended for the treatment of Achilles tendinopathy, but the clinical effect from EE has a slow onset. HYPOTHESIS The addition of low-level laser therapy (LLLT) to EE may cause more rapid clinical improvement. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS A total of 52 recreational athletes with chronic Achilles tendinopathy symptoms were randomized to groups receiving either EE + LLLT or EE + placebo LLLT over 8 weeks in a blinded manner. Low-level laser therapy (lambda = 820 nm) was administered in 12 sessions by irradiating 6 points along the Achilles tendon with a power density of 60 mW/cm(2) and a total dose of 5.4 J per session. RESULTS The results of the intention-to-treat analysis for the primary outcome, pain intensity during physical activity on the 100-mm visual analog scale, were significantly lower in the LLLT group than in the placebo LLLT group, with 53.6 mm versus 71.5 mm (P = .0003) at 4 weeks, 37.3 mm versus 62.8 mm (P = .0002) at 8 weeks, and 33.0 mm versus 53.0 mm (P = .007) at 12 weeks after randomization. Secondary outcomes of morning stiffness, active dorsiflexion, palpation tenderness, and crepitation showed the same pattern in favor of the LLLT group. CONCLUSION Low-level laser therapy, with the parameters used in this study, accelerates clinical recovery from chronic Achilles tendinopathy when added to an EE regimen. For the LLLT group, the results at 4 weeks were similar to the placebo LLLT group results after 12 weeks.

Abstract
OBJECTIVE This study was undertaken to compare the effectiveness of a protocol of combination of laser with plyometric exercises and a protocol of placebo laser with the same program, in the treatment of tennis elbow. BACKGROUND DATA The use of low-level laser has been recommended for the management of tennis elbow with contradictory results. Also, plyometric exercises was recommended for the treatment of the tendinopathy. METHODS Fifty patients who had tennis elbow participated in the study and were randomised into two groups. Group A (n = 25) was treated with a 904 Ga-As laser CW, frequency 50 Hz, intensity 40 mW and energy density 2.4 J/cm(2), plus plyometric exercises and group B (n = 25) that received placebo laser plus the same plyometric exercises. During eight weeks of treatment, the patients of the two groups received 12 sessions of laser or placebo, two sessions per week (weeks 1-4) and one session per week (weeks 5-8). Pain at rest, at palpation on the lateral epicondyle, during resisted wrist extension, middle finger test, and strength testing was evaluated using Visual Analogue Scales. Also it was evaluated the grip strength, the range of motion and weight test. Parameters were determined before the treatment, at the end of the eighth week course of treatment (week 8), and eighth (week 8) after the end of treatment. RESULTS Relative to the group B, the group A had (1) a significant decrease of pain at rest at the end of 8 weeks of the treatment (p < 0.005) and at the end of following up period (p < 0.05), (2) a significant decrease in pain at palpation and pain on isometric testing at 8 weeks of treatment (p < 0.05), and at 8 weeks follow-up (p < 0.001), (3) a significant decrease in pain during middle finger test at the end of 8 weeks of treatment (p < 0.01), and at the end of the follow-up period (p < 0.05), (4) a significant decrease of pain during grip strength testing at 8 weeks of treatment (p < 0.05), and at 8 weeks follow-up (p < 0.001), (5) a significant increase in the wrist range of motion at 8 weeks follow-up (p < 0.01), (6) an increase in grip strength at 8 weeks of treatment (p < 0.05) and at 8 weeks follow-up (p < 0.01), and (7) a significant increase in weight-test at 8 weeks of treatment (p < 0.05) and at 8 weeks follow-up (p < 0.005). CONCLUSION The results suggested that the combination of laser with plyometric exercises was more effective treatment than placebo laser with the same plyometric exercises at the end of the treatment as well as at the follow-up. Future studies are needed to establish the relative and absolute effectiveness of the above protocol.

Abstract
OBJECTIVE The aim of this study was to evaluate the effectiveness of 904-nm low-level laser therapy (LLLT) in the management of lateral epicondylitis. BACKGROUND DATA Lateral epicondylitis is characterized by pain and tenderness over the lateral elbow, which may also result in reduction in grip strength and impairment in physical function. LLLT has been shown effective in its therapeutic effects in tissue healing and pain control. METHODS Thirty-nine patients with lateral epicondylitis were randomly assigned to receive either active laser with an energy dose of 0.275 J per tender point (laser group) or sham irradiation (placebo group) for a total of nine sessions. The outcome measures were mechanical pain threshold, maximum grip strength, level of pain at maximum grip strength as measured by the Visual Analogue Scale (VAS) and the subjective rating of physical function with Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. RESULTS Significantly greater improvements were shown in all outcome measures with the laser group than with the placebo group (p < 0.0125), except in the two subsections of DASH. CONCLUSION This study revealed that LLLT in addition to exercise is effective in relieving pain, and in improving the grip strength and subjective rating of physical function of patients with lateral epicondylitis.

Abstract
BACKGROUND AND OBJECTIVES The aim of this review is to evaluate the evidence for laser acupuncture in selected orthopaedic diseases. MATERIAL AND METHODS Randomized controlled studies, meta-analyses and systematic reviews were identified by a systematic search strategy in Medline and the Cochrane library. The studies were evaluated using the quality criteria of the Oxford Centre of Evidence Based Medicine. RESULTS For the selected orthopedic diseases (medial and lateral epicondylitis, myofascial pain syndrome of the neck, back and shoulder and osteoarthritis), meta-analyses, systematic reviews and eight randomized controlled studies were found. All other published studies used laser therapy without consideration of classical acupuncture points. All studies had significant drawbacks in methodological quality and the number of patients included. In more recent trials, improvement towards higher methodological quality was obvious. Although current evidence is equivocal, positive effects can be assumed in myofascial pain syndromes of the neck, back and shoulder. Laser acupuncture is advantageous in terms of side effects compared to classical acupuncture techniques. CONCLUSION Better, well designed randomized studies with higher power are mandatory in orthopedic diseases.

Abstract
OBJECTIVE Our aim was to determine the effectiveness of low-lever laser therapy (LLLT) in the management of lateral elbow tendinopathy (LET) and to provide recommendations based on this evidence. BACKGROUND DATA LET is a common clinical condition, and a wide array of physiotherapy treatments is used for treating LET. METHODS Randomized controlled trials (RCTs) identified by a search strategy in six databases were used in combination with reference checking. RCTs that included LLLT, patients with LET, and at least one of the clinically relevant outcome measure were selected. Aqualitative analysis of the selected studies was conducted using the Chalmers' technique. RESULTS Nine RCTs fulfilled the criteria and were included in the review. Although these studies had satisfactory methodology, shortcomings were not absent; poor results were revealed as to the effectiveness of LLLT for LET management. CONCLUSIONS LLLT need not be ruled out for LET as it is a dose-response modality, and the optimal treatment dose has obviously not yet have been discovered. Further research with well-designed RCTs is needed to establish the absolute and relative effectiveness of this intervention for LET.

Abstract
A systematic review of the literature on the effectiveness of physical interventions for lateral epicondylalgia (tennis elbow) was carried out. Seventy six randomised controlled trials were identified, 28 of which satisfied the minimum criteria for meta-analysis. The evidence suggests that extracorporeal shock wave therapy is not beneficial in the treatment of tennis elbow. There is a lack of evidence for the long term benefit of physical interventions in general. However, further research with long term follow up into manipulation and exercise as treatments is indicated.

Abstract
OBJECTIVE The aim of this study was to assess the efficacy of polarized, polychromatic, non-coherent, low energy light (Bioptron 2, Bioptron AG, Switzerland) in the treatment of acute tennis elbow. BACKGROUND Tennis elbow, or lateral epicondylitis, is one of the most common lesions affecting the arm. A plethora of treatment regimes have been described for this condition, but no specific therapy has emerged as a gold standard. METHODS A pilot study was carried out with 25 patients who had acute tennis elbow. Bioptron 2 device was applied over lateral epicondyle three times per week for 4 weeks. Pain on VAS, function on VAS, and painfree grip strength were measured at the beginning (week 0) and at the end of the study (week 4). RESULTS The pain on VAS was reduced at the end of treatment (t(24) = 3.84, p = 0.001). Function on VAS was increased at the end of treatment (t(24) = 4.23, p < 0.001). Pain-free grip strength was increased at the end of treatment (t(24) = 4.23, p < 0.004). CONCLUSION Although the results suggested that the Bioptron 2 could reduce patients' symptoms with acute tennis elbow, future controlled studies are needed to establish the relative and absolute effectiveness of Bioptron 2.

Abstract
The purpose of this systematic review was to determine the effectiveness of conservative treatments for lateral epicondylitis and to provide recommendations based on this evidence. Five reviewers searched computerized bibliographic databases for articles on the conservative treatment of lateral epicondylitis from the years 1983 to 2003. A total of 209 studies were located; however, only 31 of these met the study inclusion criteria. Each of the articles was randomly allocated to reviewers and critically appraised using a structured critical appraisal tool with 23 items. Treatment recommendations were based on this rating and Sackett's Level of Evidence. This review has determined, with at least level 2b evidence, that a number of treatments, including acupuncture, exercise therapy, manipulations and mobilizations, ultrasound, phonophoresis, Rebox, and ionization with diclofenac all show positive effects in the reduction of pain or improvement in function for patients with lateral epicondylitis. There is also at least level 2b evidence showing laser therapy and pulsed electromagnetic field therapy to be ineffective in the management of this condition. Practitioners should use the treatment techniques that have strongest evidence and ensure that studies findings are generalized to patients who are similar to those reported in primary research studies in terms of patient demographics and injury presentation.

Abstract
Lateral epicondylitis is the most commonly diagnosed elbow condition and affects about 1-3% of the population at large. It produces a heavy burden of workdays lost and residual impairments. Although many treatment modalities are used, few of them rest on scientific evidence and none has been proven more effective than the others. This paucity of evidence on treatments for lateral epicondylitis may stem from several sources, including the possible self-limiting nature of the condition, the lack of pathophysiological data, the methodological shortcomings of available studies, and the existence of numerous factors influencing the outcome.

Abstract
AIM To evaluate the available evidence of the effectiveness of physiotherapy for lateral epicondylitis of the elbow. METHOD Randomised controlled trials (RCTs) identified by a highly sensitive search strategy in six databases in combination with reference checking. Two independent reviewers selected RCTs that included a physiotherapy intervention, patients with lateral epicondylitis, and at least one clinically relevant outcome measure. No language restrictions were made. Methodological quality was independently assessed by two blinded reviewers. A best evidence synthesis, including a quantitative and qualitative analysis, was conducted, weighting the studies with respect to their internal validity, statistical significance, clinical relevance, and statistical power. RESULTS 23 RCTs were included in the review, evaluating the effects of lasertherapy, ultrasound treatment, electrotherapy, and exercises and mobilisation techniques. Fourteen studies satisfied at least 50% of the internal validity criteria. Except for ultrasound, pooling of data from RCTs was not possible because of insufficient data, or clinical or statistical heterogeneity. The pooled estimate of the treatment effects of two studies on ultrasound compared to placebo ultrasound, showed statistically significant and clinically relevant differences in favour of ultrasound. There is insufficient evidence either to demonstrate benefit or lack of effect of lasertherapy, electrotherapy, exercises and mobilisation techniques for lateral epicondylitis. CONCLUSIONS Despite the large number of studies, there is still insufficient evidence for most physiotherapy interventions for lateral epicondylitis due to contradicting results, insufficient power, and the low number of studies per intervention. Only for ultrasound, weak evidence for efficacy was found. More better designed, conducted and reported RCTs are needed.

Abstract
BACKGROUND AND OBJECTIVE The purpose of the present study was to examine the effects of laser irradiation on the growth and development of fetal limb tissue. STUDY DESIGN/MATERIALS AND METHODS Day 14 fetal mouse limbs (n=168) were irradiated with gallium arsenide laser (904 nm, spot size=0.002 cm2, pulse duration=200 nanoseconds, peak power=30 mW) for 1 minute each day while being maintained in an organ culture system for 3 or 5 days at the following energy densities [O (control), 0.23, 1.37, 2.75, 3.66, and 4.58 J/cm2]. RESULTS Computer image analysis of photographic images showed that there was a significant inhibition (P < 0.05) of new tissue growth after administration of lower energy densities of laser (0.23 and 1.37 J/cm2). These low-energy densities of laser irradiation also produced increased dermal cell number and collagen fiber thickness as assessed with qualitative histologic analysis of limb development by a blinded observer. Quantitative analysis of collagen distribution by color densitometric analysis of tissue sections stained with sirus red and fast green confirmed that there was a significantly greater (P < 0.05) amount of collagen present in the dermis of limbs treated with low-energy densities of laser (0.23 and 1.37 J/cm2). CONCLUSIONS Laser irradiation directly affected the growth and development of day 14 fetal mouse limbs in an organ culture system.

Abstract
As orthopaedic surgeons, we are besieged by myths that guide our treatment of lateral epicondylitis, or "tennis elbow." This extends from the term used to describe the condition to the nonoperative and operative treatments as well. The term epicondylitis suggests an inflammatory cause; however, in all but 1 publication examining pathologic specimens of patients operated on for this condition, no evidence of acute or chronic inflammation is found. Numerous nonoperative modalities have been described for the treatment of lateral tennis elbow. Most are lacking in sound scientific rationale. This has led to a therapeutic nihilism with respect to the nonoperative management of this condition. An examination of the literature can only lead us to believe that most, if not all, common nonoperative therapeutic modalities used for the treatment of tennis elbow are unproven at best or costly and time-consuming at worst. Most of the published literature on the nonoperative treatment of patients with lateral tennis elbow consists of poorly designed trials. The selection criteria are nebulous, the control group is questionably designed, and the number of patients is often too low to avoid a serious loss of study power. These studies therefore have a high beta error, implying an inability to detect a difference between groups, even if one truly existed. If clinical signs and symptoms persist beyond the limit of acceptability of both patient and surgeon, then an array of surgical options are available. These range from a 10-minute office procedure (the percutaneous release of the extensor origin with the patient under local anesthetic) to an extensive joint denervation, in which all radial nerve branches ramifying to the lateral epicondyle are directly or indirectly divided. How is the surgeon to choose, given the fact that most of the published surgical studies are case series of one type of operation or another, consisting of patients operated on and evaluated by the same surgeon, who has a vested interest in his or her own patients' successful outcome? The orthopaedic surgeon therefore has very little on which to "hang his hat" when it comes to objective data to guide treatment of patients with lateral tennis elbow syndrome. In the final analysis we are guided simply by our own subjective viewpoint and clinical experience. In 1999, to have such a common clinical condition have such a paucity of peer-reviewed published data of acceptable scientific quality is disappointing. In this review article we will examine the "myths" of tennis elbow: the name, the salient features on history and physical examination, the diagnostic modalities, the pathology of the "lesion," the anatomy of the lateral elbow and extensor origin and why it has led to such confusion in differential diagnosis, the nonoperative and operative treatment of tennis elbow, and finally the various studies that have been carried out on elbow biomechanics as it relates to the pathoetiology of true "tennis elbow." It is our hope that the reader will emerge with a clearer picture of the pathoetiology of the condition and the scientific rationale (or lack thereof) of the various operative and nonoperative treatment modalities.

Abstract
The contribution of the sensory and autonomic nervous system to experimentally induced tennis elbow or lateral epicondylalgia was investigated by analyses of the release of neuropeptides from sensory (substance P, SP, neurokinin A, NKA, calcitonin gene-related peptide, CGRP) and sympathetic (neuropeptide Y, NPY) nerves. SP, CGRP, NKA, NPY-like immunoreactivity (-LI) was studied in rats cerebrospinal fluid (CSF), plasma and perfusates (PF) from the enthesis of the extensor carpi radialis brevis (ECRB) of the right elbow at 2, 6 and 24 h following 0.01 ml injection of either complete Freund adjuvans (FA) or 2% Carrageenan (CAR). The control group was injected with 0.01 ml saline. In general the changes of neuropeptide-LI in the CSF and plasma were similar for both treated groups compared with the controls, but they were more pronounced in the FA group than the CAR. SP-, NKA-, CGRP- and NPY-LI were significantly increased to a similar degree in the perfusates of the ECRBs of the treated groups with a greater increase in SP-LI in the FA than the CAR group compared with controls. When comparing the neuropeptide-LI in the CSF, plasma and PF between the 2 treated groups, there were thus few differences found. Generally a unilateral injection with either FA or CAR into the rat ECRB induced a similar alteration in the concentration of SP-, NKA-, CGRP- and NPY-LI in the CSF, plasma and PF at 2, 6 and 24 h following injection. However, the most pronounced changes in neuropeptide-LI occurred locally in the elbow ECRBs PF in both treated groups.

Abstract
Despite more than 30 years of experience with low level laser therapy (LLLT) or 'biostimulation' in dentistry, concerns remain as to its effectiveness as a treatment modality. Controlled clinical studies have demonstrated that while LLLT is effective for some specific applications, it is not a panacea. This paper provides an outline of the biological basis of LLLT and summarizes the findings of controlled clinical studies of the use of LLLT for specific soft tissue applications in dentistry. Areas of controversy where there is a pressing need for further research are identified.

Abstract
We have conducted a prospective, double blind trial of low level laser therapy (LLLT) in musculoskeletal injuries to assess its efficacy. We assigned patients with a variety of painful skeletal soft tissue conditions to one of two treatment groups, treatment from a functional machine, placebo treatment from an inactive machine. Both machines were identical and both appeared functional. The operative status of each machine was unknown to both the therapist and the patient. The results suggest that LLLT has no significant therapeutic effect and acts primarily as a placebo.
