ABSTRACT
CONTEXT: There is a lack of consensus on the best management approach for lateral elbow tendinopathy (LET). Recently, scapular stabilizer strength impairments have been found in individuals with LET. OBJECTIVE: The purpose of this study was to compare the effectiveness of local therapy (LT) treatment to LT treatment plus a scapular muscle-strengthening (LT + SMS) program in patients diagnosed with LET. DESIGN: Prospective randomized clinical trial. SETTING: Multisite outpatient physical therapy. PATIENTS: Thirty-two individuals with LET who met the criteria were randomized to LT or LT + SMS. INTERVENTIONS: Both groups received education, a nonarticulating forearm orthosis, therapeutic exercise, manual therapy, and thermal modalities as needed. Additionally, the LT + SMS group received SMS exercises. MAIN OUTCOME MEASURE: The primary outcome measure was the patient-rated tennis elbow evaluation; secondary outcomes included global rating of change (GROC), grip strength, and periscapular muscle strength. Outcomes were reassessed at discharge, 6, and 12 months from discharge. Linear mixed-effect models were used to analyze the differences between groups over time for each outcome measure. RESULTS: The average duration of symptoms was 10.2 (16.1) months, and the average total number of visits was 8.0 (2.2) for both groups. There were no significant differences in gender, age, average visits, weight, or height between groups at baseline (P > .05). No statistical between-group differences were found for any of the outcome measures. There were significant within-group improvements in all outcome measures from baseline to all follow-up points (P < .05). CONCLUSION: The results of this pilot study suggest that both treatment approaches were equally effective in reducing pain, improving function, and increasing grip strength at discharge as well as the 6- and 12-month follow-ups. Our multimodal treatment programs were effective at reducing pain and improving function up to 1 year after treatment in a general population of individuals with LET.

BACKGROUND: Lateral epicondylitis (LE) is a common disease especially at middle age. Different types of treatments have been used to address LE. Corticosteroid (CS) injections and dry needling (DN) are utilized options in the treatment. However, the question of which one is better has not been entirely discussed in the literature. We hypothesized that the use of DN to treat LE would be at least as effective as using CS injections. We compared the pain relief afforded and improvements in functional disability after DN and CS injection. METHODS: A total of 108 LE patients whose pain was not relieved by 3 weeks of first-line treatment were included in a randomized manner, using an online application into DN or CS groups (54 patients each). The minimum follow-up duration was 6 months. We recorded "Patient-Rated Tennis Elbow Evaluation" (PRTEE) scores before treatment and after 3 weeks and 6 months of treatment. RESULTS: Seven patients were excluded for various reasons; thus, 101 patients were finally evaluated. Before treatment, the groups were similar in terms of age, symptom duration, and PRTEE score, but after treatment, DN-treated patients showed better improvement in the PRTEE score than CS-treated patients (P < .01). Both treatments were effective (both P < .01). From assessments at 3 weeks and 6 months post-treatment, PRTEE scores decreased over time. Four CS-treated patients (7.6%) developed skin atrophy and whitening. One DN-treated patient (2.04%) could not tolerate the pain of the intervention and withdrew from treatment. CONCLUSION: DN and CS injection afforded significant improvements during the 6 months of follow-up. However, compared with CS injection, DN was more effective.

Background: To investigate the analgesic effects of vibro-acupuncture (VA), a novel acuvibrator was developed. Objectives: To compare the analgesic effects of VA with those of manual acupuncture (MA) and placebo acupuncture (PA) on subjects with normal sensory perception (Study I), experimentally induced acute pain (Study II), and clinical chronic pain (Study III). Methods: Thirty healthy volunteers (21 males, age: 20-30 years) participated in Study I. Fourteen healthy volunteers (8 males, age: 20-32 years) participated in Study II in which experimental pain was induced by injection of hypertonic saline. Fourteen patients suffering from unilateral epicondylalgia (9 males, age: 30-61 years) participated in Study III. All participants received VA, MA, and PA at LI4 and LI10 points in a randomized, crossover, and double-blinded manner. Quantitative sensory testing (QST) was performed on the ipsilateral forearm before and after each treatment. Data were analyzed using repeated-measures (RM) ANOVA. Results: A significantly higher vibration detection threshold (VDT) was observed after treatment of VA than after MA and PA (p < 0.001). No significant treatment effect on experimental pain intensity was detected (p > 0.086). Significantly lower pain intensity (p = 0.005) and a smaller drawing area (p = 0.011) of unilateral epicondylalgia were found after VA treatment than after PA. Conclusion: A specific effect on the VDT beyond that of MA and PA was evoked by VA. Patients with epicondylitis showed significantly lower pain intensity during VA than during PA. This study indicated that VA may be beneficial in individuals with clinical chronic musculoskeletal pain; however, further studies are needed.

OBJECTIVE: The aim of this study was to evaluate the effect of acupuncture/electroacupuncture, alone or combined with other interventions, on pain intensity, pain-related disability, and strength in lateral epicondylalgia (LE) of musculoskeletal origin. DATABASES AND DATA TREATMENT: Electronic databases were searched for randomized clinical trials, where at least one group received acupuncture or electroacupuncture for LE of musculoskeletal origin. To be eligible, trials had to include humans and collect outcomes on pain intensity or pain-related disability in LE. Data were extracted by two reviewers. The risk of bias (RoB) of the trials was assessed using the Cochrane RoB tool, methodological quality was assessed with the Physiotherapy Evidence Database (PEDro) score, and the level of evidence was summarized using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Standardized mean differences (SMDs) using random effects were calculated. RESULTS: A total of 14 trials (10 acupuncture) were included. The meta-analysis found a moderate effect size of acupuncture (SMD = -0.66, 95% confidence interval (CI) = -1.22 to -0.10), but not electroacupuncture (SMD = -0.08, 95% CI = -0.99 to 0.83), in the reduction of elbow pain as compared to a comparative group. Acupuncture exhibited a significant moderate effect size (SMD = -0.51, 95% CI = -0.91 to -0.11) in the improvement of related-disability. Acupuncture (SMD = 0.36, 95% CI = 0.16 to 0.57), but not electroacupuncture (SMD = 0.34, 95% CI = -0.29 to 0.98), exhibited a significant but small effect size on strength. Most significant effects were in the short term. The RoB was low but the heterogeneity of trial results led to a downgrading of the GRADE evidence level. CONCLUSION: Low-level evidence suggests positive effects of acupuncture, but not electroacupuncture, for pain, related-disability, and strength, in LE of musculoskeletal origin, in the short term.

Few studies have considered the effects of percutaneous electrolysis (PE) in the treatment of lateral epicondylalgia (LE). For this reason, the objective of this study was to compare the effects of PE with an evidence-based approach-trigger point dry needling (TDN)-in patients with LE. A randomized controlled trial was conducted in which 32 participants with LE were randomly assigned to two treatment groups, the PE group (n = 16) and the TDN group (n = 16). Both groups received four therapy sessions and an eccentric exercise program to be performed daily. The numerical pain rating scale (NPRS), pressure pain thresholds (PPT), quality of life, and range of motion were measured before treatment, at the end of treatment, and at one- and three-month follow-ups. Significant between-group mean differences were found after treatment for NPRS (p < 0.001) and flexion movement (p = 0.006). At one-month follow-up, significant mean differences between groups were found for NPRS (p < 0.001), PPT (p = 0.021), and flexion (p = 0.036). At three-months follow-up, significant mean differences between groups were found for NPRS (p < 0.001), PPT (p = 0.004), and flexion (p = 0.003). This study provides evidence that PE could be more effective than TDN for short- and medium-term improvement of pain and PPTs in LE when added to an eccentric exercise program.
ABSTRACT
OBJECTIVE: This meta-analysis evaluated the effect of dry needling alone or combined with other treatment interventions on pain, related-disability, pressure pain sensitivity, and strength in people with lateral epicondylalgia of musculoskeletal origin. DATA SOURCES: MEDLINE, CINAHL, PubMed, PEDro, Cochrane Library, SCOPUS and Web of Science databases from their inception to 5 April 2020. REVIEW METHODS: Randomized controlled trials collecting outcomes on pain, related-disability, pressure pain thresholds, or strength where one group received dry needling for lateral epicondylalgia of musculoskeletal origin. The risk of bias was assessed by the Cochrane Guidelines, methodological quality was assessed with the PEDro score, and the quality of evidence by using the GRADE approach. RESULTS: Seven studies including 320 patients with lateral epicondylalgia were included. The meta-analysis found that dry needling reduced pain intensity (SMD â1.13, 95%CI â1.64 to â0.62) and related-disability (SMD â2.17, 95%CI â3.34 to â1.01) with large effect sizes compared to a comparative group. Dry needling also increased pressure pain thresholds with a large effect size (SMD 0.98, 95%CI 0.30 to 1.67) and grip strength with a small size effect (SMD 0.48, 95%CI 0.16 to 0.81) when compared to a comparative group. The most significant effect was at short-term. The risk of bias was generally low, but the heterogenicity of the results downgraded the evidence level. CONCLUSION: Low to moderate evidence suggests a positive effect of dry needling for pain, pain-related disability, pressure pain sensitivity and strength at short-term in patients with lateral epicondylalgia of musculoskeletal origin. LEVEL OF EVIDENCE: Therapy, level 1a. REGISTRATION NUMBER: OSF Registry - https://doi.org/10.17605/OSF.IO/ZY3E8.

BACKGROUND: The treatment of first choice for lateral epicondylalgia humeri is conservative therapy. Recent findings indicate that spinal manual therapy is effective in the treatment of lateral epicondylalgia. We hypothesized that thoracic spinal mobilization in patients with epicondylalgia would have a positive short-term effect on pain and sympathetic activity. METHODS: Thirty patients (all analyzed) with clinically diagnosed (physical examination) lateral epicondylalgia were enrolled in this randomized, sample size planned, placebo-controlled, patient-blinded, monocentric trial. Pain-free grip, skin conductance and peripheral skin temperature were measured before and after the intervention. The treatment group (15 patients) received a one-time 2-min T5 costovertebral mobilization (2 Hz), and the placebo group (15 patients) received a 2-min one-time sham ultrasound therapy. RESULTS: Mobilization at the thoracic spine resulted in significantly increased strength of pain-free grip + 4.6 kg ± 6.10 (p = 0.008) and skin conductance + 0.76 µS ± 0.73 (p = 0.000004) as well as a decrease in peripheral skin temperature by - 0.80 °C ± 0.35 (p < 0.0000001) within the treatment group. CONCLUSION: A thoracic costovertebral T5 mobilization at a frequency of 2 Hz shows an immediate positive effect on pain-free grip and sympathetic activity in patients with lateral epicondylalgia. CLINICAL TRIAL REGISTRATION: German clinical trial register DRKS00013964, retrospectively registered on 2.2.2018.

BACKGROUND: Lateral epicondylalgia (tennis elbow) is a common, debilitating and often treatment-resistant condition. Two treatments thought to address the pathology of lateral epicondylalgia are hypertonic glucose plus lignocaine injections (prolotherapy) and a physiotherapist guided manual therapy/exercise program (physiotherapy). This trial aimed to compare the short- and long-term clinical effectiveness, cost effectiveness, and safety of prolotherapy used singly and in combination with physiotherapy. METHODS: Using a single-blinded randomised clinical trial design, 120 participants with lateral epicondylalgia of at least 6 weeks' duration were randomly assigned to prolotherapy (4 sessions, monthly intervals), physiotherapy (weekly for 4 sessions) or combined (prolotherapy+physiotherapy). The Patient-Rated Tennis Elbow Evaluation (PRTEE) and participant global impression of change scores were assessed by blinded evaluators at baseline, 6, 12, 26 and 52 weeks. Success rate was defined as the percentage of participants indicating elbow condition was either 'much improved' or 'completely recovered.' Analysis was by intention-to-treat. RESULTS: Eighty-eight percent completed the 12-month assessment. At 52 weeks, there were substantial, significant improvements compared with baseline status for all outcomes and groups, but no significant differences between groups. The physiotherapy group exhibited greater reductions in PRTEE at 12 weeks than the prolotherapy group (p = 0.014). CONCLUSION: There were no significant differences amongst the Physiotherapy, Prolotherapy and Combined groups in PRTEE and global impression of change measures over the course of the 12-month trial.

INTRODUCTION: Lateral epicondylalgia (LE) is a musculoskeletal injury involving the common extensor origin in elbow manifesting as pain and ineffective handgrip affecting the daily activities of the individuals with LE. OBJECTIVES: This study determined the effectiveness of Standard Biomechanical Taping (SBMT), Vector Correcting Dysfunction Techniques 1 (VCDT 1) and Vector Correcting Dysfunction Technique 2 (VCDT 2); and compared their differences on effects on pain, grip strength and daily functions of individual with unilateral LE. METHODS: A cross-over study design was used. The senior investigator applied three BMT techniques namely: a. SBMT, b. VCDT 1, and c. VCDT 2. On Day 1, SBMT and VCDT1 were randomly assigned. On Day 3, either SBMT or VCDT1 not performed on Day 1 was applied to LE elbows. On Day 5, VCDT2 was applied on LE elbows. Visual Analogue Scale (VAS), Static Maximum Handgrip Strength Test (SMHGT) and Patient-Rated Tennis Elbow Evaluation (PRTEE) were used as outcome measures administered by three blinded junior investigators. On Days 1, 3, and 5, VAS and SMGHT were administered before and during BMT application. PRTEE was administered on Days 1 and 12. RESULTS: The following were found in this study: a. significantly decreased VAS scores at Days 1, 3, and 5 of BMT application (pâ¯<â¯0.05); b. significantly improved final VAS, SMHGT strength and PRTEE scores on Day 12 compared to baseline scores on Day 1 (pâ¯=â¯/<0.01); and c. significantly decreased VAS scores when using SBMT compared to VCDT2 (pâ¯<â¯0.05). CONCLUSION: BMT is a novel taping technique effective in decreasing lateral elbow pain, increasing handgrip strength and improving function of patients with LE. BMT can be applied on painful elbows effecting a better grip among patients with LE.

BACKGROUND: Lateral epicondylitis is one of the most common overuse injuries, and has been reported to reduce function and affect daily activities. There is no standard therapy for lateral epicondylitis. In Hong Kong, acupuncture and extracorporeal shockwave therapy (ESWT) have been popular in treating lateral epicondylitis in recent years. OBJECTIVE: This study is to compare the treatment effects of acupuncture and ESWT on lateral epicondylitis. METHODS: In this study, we evaluated 34 patients (34 elbows) with lateral epicondylitis. Seventeen patients were treated by 3-week ESWT, one session per week. Another 17 were treated by 3-week acupuncture therapy, two sessions per week. The outcome measures included pain score by visual analogue scale, maximum grip strength by Jamar dynamometer, and level of functional impairment by disability of arms, shoulders, and hands questionnaire. Participants were assessed at three time points: baseline; after treatment; and 2-week follow-up. RESULTS: The two treatments showed no significant difference at any assessment time-point. Both treatment groups had significant improvement in pain score in longitudinal comparisons. No significant difference was found in maximum grip strength and functional impairment in either treatment group, but a trend of improvement could be observed. In addition, improvement in pain relief stopped when treatment ended for either groups. CONCLUSIONS: The treatment effects of acupuncture and ESWT on lateral epicondylitis were similar. The pain relief persisted for at least two weeks after treatment.
ABSTRACT
OBJECTIVES: To compare three different ultrasound-guided injections for chronic tennis elbow. DESIGN: Assessor-blinded, randomized controlled comparative trial. METHODS: 44 patients with clinically diagnosed tennis elbow, confirmed by Doppler ultrasound, received under ultrasound guidance, a single corticosteroid injection (n=14), or two injections (separated by 4 weeks) of either autologous blood (n=14) or polidocanol (n=16). Clinical and ultrasound examination was performed at baseline, 4, 12 and 26 weeks. RESULTS: Complete recovery or much improvement was greater for corticosteroid injection than autologous blood and polidocanol at 4 weeks (p<0.001, number needed to treat 1 (95% CI 1-2)). In contrast, at 26 weeks corticosteroid was significantly worse than polidocanol (p=0.004, number needed to harm 2 (1-6)). Recurrence after corticosteroid injection was significantly higher than autologous blood or polidocanol (p=0.007, number needed to harm 2 (1-4)). Corticosteroid injection produced greater reduction in tendon thickness and vascularity than autologous blood at 4 weeks only. Compared to autologous blood, polidocanol reduced tendon thickness at 4 and 12 weeks and reduced echogenicity and hyperaemia after 12 or 26 weeks respectively. CONCLUSIONS: Injections of corticosteroid cannot be recommended over polidocanol or autologous blood, because despite beneficial short-term effect there were inferior long-term effects. Whether polidocanol or autologous blood injections are effective is unknown, especially as their global effect profiles are not unlike previously reported for wait-and-see.

BACKGROUND: Non-surgical approaches to treatment of lateral epicondylitis are numerous. The aim of this systematic review is to examine randomized, controlled trials of these treatments. METHODS: Numerous databases were systematically searched from earliest records to February 2013. Search terms included "lateral epicondylitis," "lateral elbow pain," "tennis elbow," "lateral epicondylalgia," and "elbow tendinopathy" combined with "randomized controlled trial." Two reviewers examined the literature for eligibility via article abstract and full text. RESULTS: Fifty-eight articles met eligibility criteria: (1) a target population of patients with symptoms of lateral epicondylitis; (2) evaluation of treatment of lateral epicondylitis with the following non-surgical techniques: corticosteroid injection, injection technique, iontophoresis, botulinum toxin A injection, prolotherapy, platelet-rich plasma or autologous blood injection, bracing, physical therapy, shockwave therapy, or laser therapy; and (3) a randomized controlled trial design. Lateral epicondylitis is a condition that is usually self-limited. There may be a short-term pain relief advantage found with the application of corticosteroids, but no demonstrable long-term pain relief. Injection of botulinum toxin A and prolotherapy are superior to placebo but not to corticosteroids, and botulinum toxin A is likely to produce concomitant extensor weakness. Platelet-rich plasma or autologous blood injections have been found to be both more and less effective than corticosteroid injections. Non-invasive treatment methods such as bracing, physical therapy, and extracorporeal shockwave therapy do not appear to provide definitive benefit regarding pain relief. Some studies of low-level laser therapy show superiority to placebo whereas others do not. CONCLUSIONS: There are multiple randomized controlled trials for non-surgical management of lateral epicondylitis, but the existing literature does not provide conclusive evidence that there is one preferred method of non-surgical treatment for this condition. Lateral epicondylitis is a condition that is usually self-limited, resolving over a 12- to 18-month period without treatment. LEVEL OF EVIDENCE: Therapeutic Level II. See Instructions to Authors for a complete description of level of evidence.
ABSTRACT
Lateral epicondylalgia is a common orthopedic disorder. In traditional Chinese medicine, acupuncture is often used for treating lateral epicondylalgia. Laser acupuncture, compared with manual acupuncture, has more advantages because it is painless, aseptic and safe. However, the analgesic effect of manual acupuncture and laser acupuncture on lateral epicondylalgia has rarely been explored. We conducted a systematic review and meta-analysis to compare the analgesic effect of laser acupuncture and manual acupuncture for the treatment of lateral epicondylalgia. We investigated studies published in the Medline, PubMed, and CINAHL databases from January 1980 to December 2013. This review included 9 randomized articles. Six of them examined manual acupuncture and the others focused on laser acupuncture. We analyzed the meta-analysis results regarding the analgesic effect of the treatment, and observed substantial differences in 4 articles related to manual acupuncture. Manual acupuncture is effective in short-term pain relief for the treatment of lateral epicondylalgia; however, its long-term analgesic effect is unremarkable. A suitable acupuncture point and depth can be used to treat lateral epicondylalgia. Manual acupuncture applied on lateral epicondylalgia produced stronger evidence of an analgesic effect than did laser acupuncture, and further study on the analgesic effect of laser acupuncture is required.

BACKGROUND: There is an ongoing debate about the myofascial component, characterized by the presence of myofascial trigger points (MTrPs) in lateral epicondylalgia (LE). OBJECTIVES: To review current evidence of the association between myofascial pain and LE, including efficacy of treatment, focusing on myofascial pain. METHODS: PubMed, Google Scholar and PEDro databases were searched without search limitations from inception until October 2012 for terms relating to LE and MTrPs. RESULTS: Two observational studies showed a high prevalence of MTrPs in LE patients compared to healthy controls. Three randomized controlled trials demonstrated significant improvement in pain and functional outcomes after application of soft tissue techniques, focusing on the myofascial component. CONCLUSION: Myofascial pain and MTrPs may be part of the LE etiology. Treatment focusing on the myofascial component seems to be effective in reducing pain and improving function in patients with LE. Additional trials are essential to attain a solid conclusion.
