Alteration of Interhemispheric Inhibition in Patients With Lateral Epicondylalgia. THE JOURNAL OF PAIN 2024; 25:104440. [PMID: 38065465 DOI: 10.1016/j.jpain.2023.11.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Revised: 11/23/2023] [Accepted: 11/27/2023] [Indexed: 01/12/2024]
Abstract
Patients with lateral epicondylalgia (LE) show alterations in the primary motor cortex (M1) contralateral to the affected side. Cortical alterations have been investigated by measuring intracortical facilitation/inhibition; however, their association with pain remains controversial. Furthermore, no studies have investigated changes in interhemispheric inhibition (IHI). IHI can be assessed using the ipsilateral silent period (iSP) known as the temporary inhibition of electromyographic activity evoked by transcranial magnetic stimulation in the ipsilateral M1 of the contracting muscle. To better understand the relationship between cortical alterations and pain in LE, this observational study investigated the relationship between iSP and pain in LE. Twenty-seven healthy volunteers and 21 patients with LE were recruited. The duration of iSP in the extensor carpi radialis brevis was measured. The IHI asymmetry ratio was calculated to determine the IHI balance. Pain and disability were scored using the Japanese version of the patient-rated elbow evaluation. We observed increased inhibitory input from the ipsilateral M1 on the affected side to the contralateral M1 in LE. Additionally, the IHI balance correlated with pain severity. Hence, regulating imbalanced IHI can potentially decrease lateral elbow pain in LE. PERSPECTIVE: Patients with lateral epicondylalgia (LE) experience persistent pain and cortical alterations. However, there is no established relationship between cortical alterations and pain. This study demonstrated that the interhemispheric inhibition (IHI) balance is correlated with pain. Regulating imbalanced IHI can potentially decrease lateral elbow pain in patients with LE.

Does the ulnohumeral angle have a role in the aetiopathogenesis of lateral epicondylitis? Medicine (Baltimore) 2024; 103:e37944. [PMID: 38669394 PMCID: PMC11049780 DOI: 10.1097/md.0000000000037944] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Accepted: 03/29/2024] [Indexed: 04/28/2024] Open
Abstract
The pathophysiology of lateral epicondylitis (LE) remains not fully elucidated, as it involves a complex interaction of anatomical structures. The primary objective of the research is to identify a potential relationship between LE and the ulnohumeral angle (UHA), which demonstrates the coronal alignment of the elbow. Patients diagnosed with LE between September 1st, 2020, and September 1st, 2023, were retrospectively examined. Demographic information and UHA measurements of patients meeting the inclusion criteria and a control group with similar criteria were collected. Measurements were independently conducted by 2 orthopedists at a 2-week interval and compared. Among 413 patients meeting the inclusion criteria and the control group comprising 420 patients, there were no significant differences in age, gender, and side (P = .447, P = .288, P = .159, respectively). The mean UHA for the LE group was 13.49 ± 4.24, while for the control group, it was 12.82 ± 9.19, showing a significant difference (P = .026). The inter-observer and intraobserver reliability of the angle measurements were both above 0.80. We hypothesize that the increase in UHA in patients with LE reflects an adaptive change secondary to compressive forces acting on the lateral aspect of the elbow. This study is the first to describe the relationship between LE and UHA based on anatomical-biomechanical foundations, suggesting a cause-and-effect relationship. Further studies are warranted to delve deeper into this relationship.

Abstract
External humeral epicondylitis (EHE) is an inflammation and pain of the lateral tendons of the elbow with poor clinical efficacy. In this study, we aim to observe the effect of extra capsular arthroscopy (ECA) plus Traditional Chinese medicine (TCM) analgesic tincture in the treatment of EHE. A retrospective analysis was performed on the follow-up data of 58 patients with intractable EHE treated by ECA plus TCM analgesic tincture over 2 years from January 2017 to October 2018. All patients were followed up during the operation, with a mean follow-up duration of 17.6 months. There were no complications such as infection, nerve injury, wound nonunion and joint stiffness. The postoperative and pronation angles were statistically different from preoperative. The visual analogue scale (VAS) score during rest and movement of the elbow joint after operation was significantly different from that before operation. Postoperative Mayo elbow joint function score was significantly different from preoperative. Postoperative elbow joint function and brachial and shoulder dysfunction scores were statistically significant compared with those before surgery. Postoperative elbow joint function and brachial and shoulder dysfunction scores were statistically significant compared with those before surgery. The satisfaction rate of patients was 100%, with 52 cases of completely satisfied, 6 cases of basically satisfied and no dissatisfied cases. The curative effect of external capsular arthroscopy plus analgesic tincture in the treatment of external humeral epicondylitis was promising, which was worthy of clinical promotion.

Abstract
Lateral epicondylitis, also termed as "tennis elbow," is the most common cause of elbow pain and dysfunction, mainly resulting from repetitive gripping or wrist extension during various activities. The exact pathogenesis remains largely elusive with putative tendinosis, a symptomatic degenerative process of the local tendon. It is usually diagnosed by clinical examinations. Sometimes, additional imaging is required for a specific differential diagnosis. Although most cases can be self-healing, the optimal treatment strategy for chronic lateral epicondylitis remains controversial. This article presents a landscape of emerging evidence on lateral epicondylitis and focuses on the pathogenesis, diagnosis, and management, shedding light on the understandings and treatment for healthcare professionals.

Abstract
STUDY DESIGN Randomized clinical trial. INTRODUCTION KinesioTape (KT) is a noninvasive method to treat pain and muscular dysfunction. PURPOSE To investigate the effect of KT with and without tension on pain intensity, pain pressure threshold, grip strength and disability in individuals with lateral epicondylitis, and myofacial trigger points in forearm muscles. METHODS Thirty women with lateral epicondylitis and myofacial trigger point in forearm muscles were randomly assigned to KT with tension and placebo (KT without tension). The treatment was provided 3 times in one week, and outcome measures were assess pre-post treatment. RESULTS The mean score of visual analogue scale (VAS) during activity decreased significantly from 6.4 and 6 pretest to 2.53 and 4.66 posttest, respectively, for the KT with and without tension groups. The mean score of Disabilities of the Arm, Shoulder and Hand decreased significantly from 16.82 and 22.79 pretest to 8.65 and 8.29 posttest, respectively, for the KT with and without tension groups. A paired t-test revealed a significant reduction in VAS during activity and Disabilities of the Arm, Shoulder and Hand before and after treatment in both groups (P < .05). Pain pressure threshold, grip strength, and VAS using an algometer revealed no significant differences. The study showed no significant difference in variables immediately after intervention. DISCUSSION Improvements in functional disability were superior when KT was used with tension, than obtained with a placebo-no tension application. CONCLUSION The application of KT produces an improvement in pain intensity and upper extremity disability in subjects with LE and MTP in forearm muscles, and KT with tension was more effective than placebo group.

Abstract
BACKGROUND The aim of this study was to compare the short-term and intermediate-term efficacy of acupuncture plus fire needle therapy with that of acupuncture alone in the treatment of lateral epicondylitis (LE). METHODS Thirty-eight patients with LE who had persisted for at least 2 months were enrolled in this prospective, assessor-blinded, randomized controlled pilot trial. Twenty-one patients were randomized to the acupuncture plus fire needle group and 17 to the acupuncture-only group. The primary outcome was the visual analog scale pain score for the previous 24 hours and the secondary outcomes were the maximum grip strength, Patient-rated Forearm Evaluation Questionnaire score, and Medical Outcomes Study 36-Item Short-form Health Survey score. The values at baseline (pretreatment), at the end of treatment, and at 3 months after treatment were used to assess the short-term and intermediate-term effects of treatment. The data were analyzed using the Chi-square test and t test. RESULTS Within-group analyses showed better results for acupuncture plus fire needle therapy in the short term and intermediate term. Differences in the severity of pain and secondary outcomes were significant in the intermediate term in the acupuncture group. At the end of treatment, none of the differences in outcome scores were significant, except for maximum grip strength in the affected hand in the acupuncture group. No significant between-group differences in short-term or intermediate-term outcomes were observed. CONCLUSION Acupuncture plus fire needle therapy was effective in the short term in patients seeking improvement of LE. Twelve treatments were effective for relieving pain and improving disability in the intermediate term in patients with chronic LE in both study groups. The findings of the pilot study confirm the feasibility of proceeding to a larger randomized controlled study of the longer-term effects of acupuncture plus fire needle therapy in patients with LE.

Abstract
OBJECTIVE The aim of this study was to compare the efficacy of extracorporeal shock wave therapy (ESWT) and therapeutic ultrasound (US) in the treatment of lateral epicondylosis (LE). METHODS Our study enrolled 50 patients with LE. Patients were randomized into two groups. Group 1 underwent therapeutic US (n = 24; 5 males and 15 females; mean age: 43.75 ± 4.52) Group 2 underwent ESWT (n = 20; 8 males and 16 females; mean age: 46.04 ± 9.24). Patients were evaluated at baseline, after treatment,and 1 month following treatment. The outcome measures were the visual analog scale (VAS), algometer, grip dynamometer, quick-disability of the arm,shoulder,and hand (QDASH), patient-rated tennis elbow evaluation (PRTEE), and Short Form-36 (SF-36) health survey questionnairre. RESULTS Both groups showed significant improvements in terms of VAS (all p values < 0.0001), dynamometer (p = 0.001 vs p = 0.015), algometer (all p values < 0.0001), PRTEE (all p values < 0.0001), QDASH (all p values < 0.0001), and SF-36 scores (p = 0.001 vs p = 0.005) within time. There was no significant difference between the two groups, except algometer scores in favor of ESWT (p = 0.029). CONCLUSION ESWT and therapeutic US are equally effective in treating LE. ESWT is an alternative therapeutic intervention and as effective as US. LEVEL OF EVIDENCE Level III, Therapeutic study.

Abstract
Numerous surgical options have been introduced for the treatment of chronic refractory lateral epicondylitis of the elbow, but it remains unclear which option is superior. The clinical outcomes of an open surgery group and an arthroscopic surgery group were evaluated, and the results of the 2 procedures were compared. From among patients with lateral epicondylitis refractory to 6 months of conservative treatment, 68 patients satisfying study criteria were recruited. Open surgery was performed in 34 cases (group 1), and arthroscopic surgery was performed in 34 cases (group 2). Compared with preoperatively, the 2 groups had significantly improved values for grip strength, range of motion, and Disabilities of the Arm, Shoulder and Hand score at 12 months postoperatively. Group 1 had significantly greater improvements in grip strength and visual analog scale pain score compared with group 2 (P=.048 vs P=.006). Group 2 had significantly greater (P=.045) improvement in pronation compared with group 1. Group 2 returned to work sooner than group 1. On the questionnaire regarding satisfaction with surgery 24 months postoperatively, 4 patients (12%) in group 2 reported dissatisfaction compared with no patients in group 1. Open surgery and arthroscopic surgery both yielded good clinical results. Nonetheless, for patients requiring muscle strength or having severe pain at work, open surgery would be more effective.

Abstract
PURPOSE To compare the clinical effects of radiofrequency (RF)-based microtenotomy and arthroscopic release of the extensor carpi radialis brevis (ECRB) tendon in patients with recalcitrant lateral epicondylitis through a prospective randomized controlled study. METHODS A total of 46 patients were randomly assigned to receive arthroscopic release (group A, 24 patients) or RF-based microtenotomy (group B, 22 patients). The visual analog scale (VAS) score for pain, flexion-extension arc, operation time, Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH), Mayo Elbow Performance Score (MEPS), and grip power of groups A and B were compared during the recovery phases for up to 2 postoperative years. RESULTS Both groups showed statistically significant functional improvement compared with their preoperative grip strength and DASH, VAS, and MEPS scores at 2 years after surgery (P < .05). There were no differences in postoperative pain relief or functional restoration between the 2 groups during the recovery phases, however the mean operation time for group B (41.4 ± 5.2 minutes) was significantly shorter than that for group A (15.6 ± 3.6 minutes, P < .001). In group B, 1 patient underwent revision surgery due to postoperative ECRB rupture, and 1 patient in group A underwent open release for persistent postoperative discomfort. CONCLUSIONS RF-based microtenotomy for treating recalcitrant lateral epicondylitis provided clinical outcomes comparable with those from arthroscopic release of ECRB tendon during the recovery phase. RF-based microtenotomy is considered as one of the surgical procedures for treating recalcitrant lateral epicondylitis, with the advantages of reliable elbow functional restoration and significantly shorter operation time.

Abstract
OBJECTIVES The aim of this study was to compare the diagnostic performance of different sonographic modalities for diagnosing lateral epicondylosis. METHODS A total of 50 symptomatic and 50 asymptomatic common extensor tendons in 44 patients with lateral epicondylosis, and 25 healthy participants were prospectively examined by B-mode sonography, color Doppler imaging, power Doppler imaging, Superb Microvascular Imaging (SMI; Toshiba Medical Systems Corporation, Tokyo, Japan), and strain elastography. We evaluated blood flow in common extensor tendons by using a grading system with color Doppler imaging, power Doppler imaging, and SMI. The diagnostic performance of the modalities was compared. RESULTS When a cutoff value of hypoechogenicity was used for the mean strain ratio, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy rates were 92.0%, 94%.0, 93.9%, 92.2%, and 93.0%, respectively. When a cutoff point of grade 1 was used, the sensitivity, specificity, PPV, NPV, and accuracy rates were 26.0%, 10.0%, 10.0%, 57.5%, and 63.0, for color Doppler imaging; 40.0%, 10.0%, 10.0%, 62.5%, and 70.0% for power Doppler imaging; and 84.0%, 94.0%, 93.0%, 85.5%, and 89.0% for SMI. When a cutoff value of 3.94 was used for the mean strain ratio, the sensitivity, specificity, PPV, NPV, and accuracy rates were 78.0%, 92.0%, 90.7%, 80.7%, and 85.0%, respectively. A statistically significant correlation was detected between SMI, strain elastography, and visual analog scale scores (P < .001). CONCLUSIONS The combination of SMI and B-mode sonography was found to have excellent diagnostic performance for lateral epicondylosis. Neovascularzation in patients' tendons with lateral epicondylosis was identified much better with SMI compared to color or power Doppler imaging.

Abstract
PURPOSE Lateral epicondylitis is generally considered an extra-articular condition. The role of minor instability in the aetiology of lateral elbow pain has rarely been considered. The aim of this study was to evaluate the correlation of lateral ligamentous laxity with aspects of intra-articular lateral elbow pathology and investigate the role of minor instability in lateral elbow pain. METHODS Thirty-five consecutive patients aged between 20 and 60 years with recalcitrant lateral epicondylitis who had failed conservative therapy and had no previous trauma or overt instability, were included. The presence of three signs of lateral ligamentous patholaxity and five intra-articular findings were documented during arthroscopy. The relative incidence of each of these was calculated, and the correlation between patholaxity and intra-articular pathology was evaluated. RESULTS At least one sign of lateral ligamentous laxity was observed in 48.6% of the studied cohort, and 85.7% demonstrated at least one intra-articular abnormal finding. Radial head ballottement was the most common sign of patholaxity (42.9%). Synovitis was the most common intra-articular aspect of pathology (77.1%), followed by lateral capitellar chondropathy (40.0%). A significant correlation was found between the presence of lateral ligamentous patholaxity signs and capitellar chondropathy (p = 0.0409), as well as anteromedial synovitis (p = 0.0408). CONCLUSIONS Almost one half of patients suffering from recalcitrant lateral epicondylitis display signs of lateral ligamentous patholaxity, and over 85% demonstrate at least one intra-articular abnormality. The most frequent intra-articular findings are synovitis and lateral capitellar chondropathy, which correlate significantly with the presence of lateral ligamentous patholaxity. The fact that several patients demonstrated multiple intra-articular findings in relation to laxity provides support to a sequence of pathologic changes that may result from a symptomatic minor instability of the lateral elbow (SMILE) condition.

Abstract
OBJECTIVE We conducted this study in order to find out the demographic causes of pathology for chronic lateral elbow pain along arthroscopic criteria. MATERIAL AND METHOD We conducted descriptive study of the medical records of the patients with chronic lateral elbow pain who refractory to conservative treatment. Diagnostic arthroscopy of the elbow was performed by a specialist in elbow surgery at HRH Princess Maha Chakri Sirindhorn Medical Center from March 2011 to October 2014. RESULTS There were 29 patients who met inclusion criteria in our study. With regard to intra-articular pathologies, we found a radiocapitellaplica in 41% of the patients. In 21% of the patients, we found isolated tennis elbow. The concomitant radiocapitellaplica and tennis elbow were also found in 21% of patients. Cartilage lesion was found in 10% of the patients and plica with posterolateral impingement was found in 7% of patients. CONCLUSION Causes of the chronic lateral elbow pain are complex. The diagnosis should be made by precise clinical sign and proper investigations. In our series, the lateral epicondylitis was not the majority cause of chronic lateral elbow pain. The benefits of arthroscopy are not just the minimal invasive approach directly to the lesion, but also the intra-articular and dynamic investigation allow the surgeon to make sure that all pathology were treated.

Abstract
The relative contributions of the forearm extensors to the tensile force at the lateral epicondyle were examined by implanting a force transducer in the common extensor tendon of four soft fixed cadaver elbows and sequentially stretching each muscle arising from the lateral epicondye. Extensor carpi radialis brevis and extensor digitorum communis produced the largest increases while the superficial head of supinator produced a moderate increase in tensile force in the common extensor tendon. Extensor carpi radialis longus and extensor carpi ulnaris had no significant effect. Radial tunnel pressure was measured using a balloon catheter in a separate study of five cadaver elbows. Radial tunnel pressure increased on moving the wrist from neutral to a flexion–pronation position. This positional rise in pressure was reduced by supinator musculotendinous lengthening (77%) while lengthening of the extensor carpi radialis brevis and extensor digitorum communis had no effect. This study demonstrates a biomechanical basis for the superficial head of supinator in the aetiology of both lateral epicondylitis and radial tunnel syndrome.

The Potential Risk Factors Relevant to Lateral Epicondylitis by Wrist Coupling Posture. PLoS One 2016; 11:e0155379.

Abstract
The use of awkward wrist postures and unskilled techniques might induce lateral epicondylitis. This study thus investigated the effects of wrist deviation combined with extension and movement velocity on the dynamic performances of the wrist muscles during the coupling posture via a custom-made bi-planar isokinetic dynamometer. Thirty subjects were recruited to perform the isokinetic testing. We measured the muscle strengths and activities for the wrist extensors and flexors during concentric and eccentric contractions at three movement velocities, 30°s-1, 90°s-1, and 180°s-1, combined with three wrist postures, neutral position (NP), radial deviation (RD), and ulnar deviation (UD). The root mean square (RMS) of the electromyographic signal in the extensor digitorum communis (EDC), normalized peak torque of extensors, and ratio of normalized peak torque between wrist extensors and flexors, were all greater in the NP than RD and UD in both contractions. The ratio of RMS between EDC and flexor digitorum superficialis (FDS) had a significantly greater value in RD than UD during the concentric contraction. The EDC showed significantly higher activity at the fast velocity in both contractions. Nevertheless, a significantly higher RMS of the electromyographic signal between EDC and FDS and the ratio of strength between wrist extensors and flexors were found at slow velocity in both contractions. The wrist deviation combined with extension and movement velocity of the wrist joint should thus be considered as influential factors which might alter the dynamic performances, and may result in further injury of the elbow joint.

Abstract
The goals of this study were to (1) assess how frequently patients present for evaluation of common hand disorders in relation to hand dominance and (2) evaluate the effect of hand dominance on function in patients with these conditions. The authors hypothesized that (1) the majority of patients who seek evaluation would have a condition that affects the dominant hand, and (2) disability scores would be worse if the dominant hand is involved. They retrospectively reviewed the records of consecutive patients who presented for treatment to their institution with unilateral symptoms of 5 common disorders of the hand: carpal tunnel syndrome (CTS), de Quervain's tenosynovitis (DEQ), lateral epicondylitis (LE), hand osteoarthritis (OA), and trigger finger (TF). The authors assessed the effect of diagnosis and hand dominance on Disabilities of the Arm, Shoulder and Hand (DASH) scores. The study group comprised 1029 patients (379 men and 650 women) with a mean age of 59.5 years. Ninety percent were right-hand dominant. The dominant and nondominant hands were affected with relatively equal frequency for CTS, DEQ, OA, and TF (range, 45%-53%). Patients with LE had a significantly higher incidence of dominant hand involvement. Men had lower DASH scores than women by an average of 7.9 points, and DASH scores were significantly but slightly higher for the overall group (3.2 points) when the dominant side was affected. Men with LE and women with TF and OA had significantly higher DASH scores when their dominant extremity was affected. Common hand disorders such as CTS, DEQ, OA, and TF affect the dominant and nondominant hands in roughly equivalent proportions, whereas LE is more common on the dominant side. Dominant hand involvement results in significantly worse DASH scores, although the magnitude of this is relatively small. Women have significantly higher DASH scores than men for the conditions evaluated. [Orthopedics. 2016; 39(3):e444-e448.].

Abstract
The aim of the study is to determine the inter-reliability and intra-observer reliability of magnetic resonance imaging (MRI) for lateral epicondylitis and investigate whether there is a potential relationship between MRI abnormalities of the common extensor tendon (CET) and its clinical symptom.The study group comprised 96 consecutive patients (46 men and 50 women) with a clinical diagnosis of chronic lateral epicondylitis, which were examined on 3.0 T MR. An MRI scoring system was used to grade the degree of tendinopahty. Three independent musculoskeletal radiologists, who were blinded to the patients' clinical information, scored images separately. Clinical symptoms were assessed using the Patient-Rated Tennis Elbow Evaluation (PRTEE).Of all the patients, total 96 elbows had MRI-assessed tendinopathy, including 38 (39.6%) with grade 1, 31 (32.3%) with grade 2, and 27 (28.1%) with grade 3. Inter-observer reliability and intra-observer agreement for MRI interpretation of the grades of tendinopathy was good, and a positive correlation between the grades of tendinopathy and PRTEE was determined.MRI is a reliable tool in determining radiological severity of chronical lateral epicondylitis. The severity of MR signal changes positively correlate with the patient's clinical symptom.

Epicondylitis and corticosteroid injection: fewer cures at one year. PRESCRIRE INTERNATIONAL 2015; 24:160-161. [PMID: 26436174] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/05/2023]
Abstract
Corticosteroid injection provides short-term relief for patients with epicondylitis. However, in a trial lasting one year, corticosteroid injection resulted in a lower complete recovery rate and higher recurrence rate. Physiotherapy appears to improve symptoms in the short-term without affecting outcome at one year.

Abstract
BACKGROUND Core stability and flexibility, features of Pilates exercise, can reduce loads to the upper extremities. Reducing loads is essential to improve symptoms for individuals with lateral epicondylosis. Although Pilates exercise has gained popularity in healthy populations, it has not been studied for individuals with lateral epicondylosis. OBJECTIVE The purpose of this study was to determine if adding Pilates-based intervention to standard occupational therapy intervention improved outcomes as measured by the Patient-Rated Tennis Elbow Evaluation (PRTEE) more than standard intervention for individuals with lateral epicondylosis. METHODS Participants (N= 17) were randomized to the standard intervention group or Pilates-based intervention group. All participants received standard intervention. The Pilates-based intervention group additionally completed abdominal strengthening, postural correction, and flexibility. RESULTS For both groups, paired t-tests showed significantly improved PRTEE scores, 38.1 for the Pilates-based intervention group, and 22.9 for the standard intervention group. Paired t-test showed significantly improved provocative grip strength and pain for both groups. Independent t-tests showed no significant difference between groups in improved scores of PRTEE, pain, and provocative grip. CONCLUSIONS Although the Pilates-based intervention group showed greater improvement in PRTEE outcome, provocative grip, and pain, scores were not significantly better than those of the standard intervention group, warranting further research.

Effects of extracorporeal shock wave therapy on functional and strength recovery of handgrip in patients affected by epicondylitis. ULTRASOUND IN MEDICINE & BIOLOGY 2014; 40:2830-2840.

Abstract
Extracorporeal shock wave therapy (ESWT) is effective in the treatment of tendinopathy. We designed a prospective observational clinical study to assess the correlation between clinical and functional measures and recovery of strength after ESWT for epicondylitis. We analyzed 26 patients. We measured progressive improvement in visual analogue scale values (p < 0.0005) and Mayo Elbow Performance Index scores (p = 0.004) for the pathologic limb. Monitoring of handgrip failed to reveal changes in values at any follow-up (p > 0.05). We found no correlation between degree of clinical function and muscle deficit during follow-up. After ESWT, there was a tendency toward a decrease in grip strength, especially in the dominant limb. This could be related to the effects of ESWT, which reduces spasticity in painful hypertonic muscles. These data may be useful in defining the expectations for function during ESWT for epicondylitis, particularly for elite athletes.

Abstract
Overuse injuries of the lateral and medial elbow are common in sport, recreational activities, and occupational endeavors. They are commonly diagnosed as lateral and medial epicondylitis; however, the pathophysiology of these disorders demonstrates a lack of inflammation. Instead, angiofibroblastic degeneration is present, referred to as tendinosis. As such, a more appropriate terminology for these conditions is epicondylosis. This is a clinical diagnosis, and further investigations are only performed to rule out other clinical entities after conventional therapy has failed. Yet, most patients respond to conservative measures with physical therapy and counterforce bracing. Corticosteroid injections are effective for short-term pain control but have not demonstrated long-term benefit.

Abstract
OBJECTIVE The objective of this prospective study is to investigate the exposure-response relationships between various workplace physical exposures of force, repetition, and their combination assessed at an individual level with lateral epicondylitis (LE). BACKGROUND Workplace upper extremity musculoskeletal disorders (UEMSDs) are prevalent, disabling, and expensive. LE is one of the major UEMSDs in active workers. METHOD We used detailed health history, symptoms, and physical examination for identifying incidence and detailed exposure assessment to capture work tasks of each worker and to measure quantitative mechanical workload. We used counting process style input of proportional hazards regression for modeling cumulative incidence that accounts for changed exposure estimates during the follow-up period when respondents change jobs. RESULTS The incidence rate of LE on the dominant side was 4.91 per 100 person-years. Adjusted for age and gender, the combined effect of forearm pronation > or = 45 degrees for > or = 40% of time and time spent with forceful exertion, including any power grip (hazard ratio [HR] = 2.8, 95% confidence interval [CI] = [1.35-5.77]), lifting for > or = 3% of time (HR = 2.50, 95% CI = [1.19-5.24]), and duty cycle for forceful exertion for > or = 10% (HR = 2.25, 95% CI = [1.09-4.66]), were significant predictors of dominant side LE, whereas neither the awkward posture nor the forceful exertion alone was significant. Older workers with jobs requiring a high percentage of time working with force in combination with awkward postures of forearm were more likely to predict LE. CONCLUSION This study shows the evidence of the etiologic role of strenuous manual tasks in the occurrence of LE.

Abstract
BACKGROUND Strength training has been proposed by several authors to treat Lateral Epicondylitis. However, there is still a lack of information concerning muscle weakness and its relationship to imbalances and fatigability of forearm muscles during dynamic conditions in subjects after epicondylitis recovery. AIM To analyze the relationship between lateral humeral epicondylitis, and forearm muscle strength and fatigue. SETTING Rehabilitation specialized center POPULATION Cross-sectional study in eight former epicondylitis men free of symptoms and actively working at the moment of the evaluation and eight healthy men volunteers. METHODS Isokinetic tests were performed at different velocities in order to assess strength in concentric and eccentric contractions. Additionally, a long-term concentric test was carried out in order to analyze strength during endurance. The following variables were analyzed: Average torque of dorsal and palmar flexors of the wrist and ratio of agonist/antagonist for non-endurance contractions; length of initial and final plateaus and the slope of average torque decay during the endurance test. RESULTS In both groups, average torque produced by palmar flexor muscles was higher than that produced by dorsal flexor muscles. Patients showed higher strength in palmar flexor muscles, whereas dorsal flexor strength was similar for both populations. Palmar flexor vs. dorsal flexor ratio was significantly higher in patients for eccentric contractions. Regarding fatigue, results showed that torque decreased earlier in patients. CONCLUSIONS AND CLINICAL REHABILITATION IMPACT: Both palmar flexor force and palmar/dorsal ratio in eccentric exercise were significantly higher in patients. This finding indicates a muscular imbalance in patients underlying the epicondylitis condition. Additionally, former patients fatigued earlier. Findings indicate that muscle imbalances and fatigability might be related to lateral epicondylitis. This information may be useful in the design and monitoring of programs intended for lateral epicondylitis rehabilitation. More studies are necessary to conclude if these differences are cause or consequence of the epicondylitis.

Abstract
BACKGROUND Lateral epicondylitis is the most frequent cause of pain around the elbow joint. It causes pain in the region of the elbow joint and results in dysfunction of the elbow and deterioration of the quality of life. The purpose of this study is to compare the effects of ipsilateral acupuncture, contralateral acupuncture and sham acupuncture on lateral epicondylitis. METHODS/DESIGN Forty-five subjects with lateral epicondylitis will be randomized into three groups: the ipsilateral acupuncture group, contralateral acupuncture group and the sham acupuncture group. The inclusion criteria will be as follows: (1) age between 19 and 65 years with pain due to one-sided lateral epicondylitis that persisted for at least four weeks, (2) with tenderness on pressure limited to regions around the elbow joint, (3) complaining of pain during resistive extension of the middle finger or the wrist, (4) with average pain of NRS 4 or higher during the last one week at a screening visit and (5) voluntarily agree to this study and sign a written consent. Acupuncture treatment will be given 10 times in total for 4 weeks to all groups. Follow up observations will be conducted after the completion of the treatment, 8 weeks and 12 weeks after the random assignment. Ipsilateral acupuncture group and contralateral acupuncture group will receive acupuncture on LI4, TE5, LI10, LI11, LU5, LI12 and two Ashi points. The sham acupuncture group will receive treatment on acupuncture points not related to the lateral epicondylitis using a non-invasive method. The needles will be maintained for 20 minutes. The primary outcome will be differences in the visual analogue scale (VAS) for elbow pain between the groups. The secondary outcome will be differences in patient-rated tennis elbow evaluation (PRTEE), pain-free/maximum grip strength (Dynamometer), pressure pain threshold, clinically relevant improvement, patient global assessment, and the EQ-5D. The data will be analyzed with the paired t-test and ANCOVA (P <0.05). DISCUSSION The results of this study will allow evaluation of contralateral acupuncture from two aspects. First, if the contralateral acupuncture shows the effects similar to ipsilateral acupuncture, this will establish clinical basis for contralateral acupuncture. Second, if the effects of contralateral acupuncture are not comparable to the effects of ipsilateral acupuncture, but are shown to be similar to the effects of the sham acupuncture, we can establish the basis for using the same acupoints of the unaffected side as a control in acupuncture clinical studies.

The complexities associated with the anatomy, biomechanics, and pathophysiology of lateral epicondylalgia have resulted in numerous treatment options for this common overuse syndrome. Choosing an appropriate treatment option from such an array can be challenging. To assist therapists with this challenge, these authors created a classification model that categorizes patients by using information from common signs and symptoms. Such categorization can assist therapists in identifying appropriate treatment options

Abstract
There is a serious lack of quantitative data regarding exposure-response relationships between occupational risk factors and musculoskeletal elbow and hand disorders. This paper explores such relationships in group-level data from our earlier cross-sectional studies. Prevalence of complaints (Nordic Questionnaire) and diagnoses (physical examination) were recorded in 19 groups of female workers (1891 individuals), and 8 groups of male workers (761 individuals), with highly similar work tasks within each group. Linear regression was performed on the group means of wrist postures and angular velocity (obtained by electrogoniometers), as well as muscular load (obtained using electromyography), recorded in representative sub-samples, and psychosocial exposure (Job Content Questionnaire). To tackle within-group variations in physical exposure, sensitivity analyses were performed by bootstrapping simulations, rendering confidence intervals. The sex-adjusted slope of the regression line (β) for wrist angular velocity vs. complaints during the past 7 days was 0.6%/(°/s), (95% CI 0.3-0.9), and for carpal tunnel syndrome (CTS) 0.2%/(°/s), (0.1-0.3). For palmar flexion, p50, β over the past 7 days was 0.8%/° (0.4-1.2); for CTS 0.3%/° (0.1-0.5); β for muscular activity p90: 0.9%/%MVE (0.3-1.6), and 0.3%/%MVE (-0.03-0.6) respectively and finally β for muscular rest: -1.2%/%time (-2.4-0.03) and -0.5%/%time (-0.9 to -0.01). Relationships were also demonstrated for low job control, job strain and isostrain. Women exhibited a higher prevalence of complaints than men. In conclusion, we have established quantitative exposure-response relationships between physical work load and elbow/hand disorders. Wrist angular velocity was the most consistent risk factor.

Abstract
IMPORTANCE Corticosteroid injection and physiotherapy, common treatments for lateral epicondylalgia, are frequently combined in clinical practice. However, evidence on their combined efficacy is lacking. OBJECTIVE To investigate the effectiveness of corticosteroid injection, multimodal physiotherapy, or both in patients with unilateral lateral epicondylalgia. DESIGN, SETTING, AND PATIENTS A 2 × 2 factorial, randomized, injection-blinded, placebo-controlled trial was conducted at a single university research center and 16 primary care settings in Brisbane, Australia. A total of 165 patients aged 18 years or older with unilateral lateral epicondylalgia of longer than 6 weeks' duration were enrolled between July 2008 and May 2010; 1-year follow-up was completed in May 2011. INTERVENTIONS Corticosteroid injection (n = 43), placebo injection (n = 41), corticosteroid injection plus physiotherapy (n = 40), or placebo injection plus physiotherapy (n = 41). MAIN OUTCOME MEASURES The 2 primary outcomes were 1-year global rating of change scores for complete recovery or much improvement and 1-year recurrence (defined as complete recovery or much improvement at 4 or 8 weeks, but not later) analyzed on an intention-to-treat basis (P < .01). Secondary outcomes included complete recovery or much improvement at 4 and 26 weeks. RESULTS Corticosteroid injection resulted in lower complete recovery or much improvement at 1 year vs placebo injection (83% vs 96%, respectively; relative risk [RR], 0.86 [99% CI, 0.75-0.99]; P = .01) and greater 1-year recurrence (54% vs 12%; RR, 0.23 [99% CI, 0.10-0.51]; P < .001). The physiotherapy and no physiotherapy groups did not differ on 1-year ratings of complete recovery or much improvement (91% vs 88%, respectively; RR, 1.04 [99% CI, 0.90-1.19]; P = .56) or recurrence (29% vs 38%; RR, 1.31 [99% CI, 0.73-2.35]; P = .25). Similar patterns were found at 26 weeks, with lower complete recovery or much improvement after corticosteroid injection vs placebo injection (55% vs 85%, respectively; RR, 0.79 [99% CI, 0.62-0.99]; P < .001) and no difference between the physiotherapy and no physiotherapy groups (71% vs 69%, respectively; RR, 1.22 [99% CI, 0.97-1.53]; P = .84). At 4 weeks, there was a significant interaction between corticosteroid injection and physiotherapy (P = .01), whereby patients receiving the placebo injection plus physiotherapy had greater complete recovery or much improvement vs no physiotherapy (39% vs 10%, respectively; RR, 4.00 [99% CI, 1.07-15.00]; P = .004). However, there was no difference between patients receiving the corticosteroid injection plus physiotherapy vs corticosteroid alone (68% vs 71%, respectively; RR, 0.95 [99% CI, 0.65-1.38]; P = .57). CONCLUSION AND RELEVANCE Among patients with chronic unilateral lateral epicondylalgia, the use of corticosteroid injection vs placebo injection resulted in worse clinical outcomes after 1 year, and physiotherapy did not result in any significant differences.

Abstract
Isokinetic exercises have been extensively used in order to analyze muscle imbalances and changes associated with fatigue. It is known that such changes are difficult to assess from EMG signals during dynamic contractions, especially, using linear signal processing tools. The aim of this work was to use nonlinear prediction in order to analyze muscle couplings and interactions in this context and to assess the load-sharing of different muscles during fatigue. Results show promising for detecting interaction strategies between muscles and even for the interaction between muscles and the output torque during endurance tests.

Abstract
OBJECTIVE To analyze the short-term effectiveness of repairing musculus extensor carpi radialis brevis (ECRB) and extensor digitorum communis (EDC) tendon using suture anchor after debridement of extensor tendon insertion for recalcitrant lateral epicondylitis. METHODS Between March 2009 and May 2011, 10 patients (10 elbows) with recalcitrant lateral epicondylitis received repair of the ECRB and EDC tendon to the lateral epicondyle using a single suture anchor after debridement of extensor tendon insertion. There were 6 males and 4 females with an average age of 45.4 years (range, 36-57 years). The dominant elbow was involved in 8 patients and nondominant elbow in 2 patients; there were 4 manual workers and 6 ordinary workers. The disease duration ranged from 8 to 24 months (mean, 12.3 months). All patients had epicondylus lateralis humeri pain, local swelling and tenderness, and positive Mill sign. The average elbow range of motion (ROM) was 11.3 degrees (range, 0-30 degrees) in extension and was 132.5 degrees (range, 120-145 degrees) in flexion. Preoperative MRI showed external humeral epicondylitis in all patients. RESULTS Primary wound healing was obtained in all patients without complications of infection, leakage of joint fluid, and stiffness of elbow. Ten patients were followed up 4 to 23 months with an average of 12 months (more than 12 months in 7 cases). The time to return to work was (3.75 +/- 0.95) months for manual workers and was (2.91 +/- 0.20) months for ordinary workers, showing no significant difference (t = 1.715, P = 0.180). Compared with preoperation, the mean visual analogue scale (VAS) score significantly decreased (P < 0.05), and Mayo score and the grip strength of dominant and nondominant significantly increased (P < 0.05), but no significant difference was found when compared with non-surgical side at last follow-up (P > 0.05). At last follow-up, the average ROM was -1.5 degrees (range, 0-10 degrees) in extension and was 150.5 degrees (range, 140-160 degrees) in flexion. CONCLUSION To suture anchor for repairing the ECRB and EDC after debridement is a satisfactory procedure to treat recalcitrant lateral epicondylitis. It can effectively prevent loss of the forearm extensor strength, relieve the pain, recover the grip strength, and obtain good results.

Abstract
PURPOSE To verify the effect of a newly-developed cylindrical type forearm brace, which was designed to give focal counterforce perpendicularly on the muscle belly of the wrist extensor. MATERIALS AND METHODS The dominant hands of 24 (12 males, 12 females) healthy subjects were tested. Two types of forearm braces (focal cylindrical type and broad pneumatic type) were examined. The braces were applied at the extensor carpi radialis brevis, 5 to 7 cm distal to the lateral epicondyle. Two surface electrodes were attached to the proximal and distal parts of the brace. By quantitative electromyography, the mean amplitudes of voluntary extensor carpi radialis brevis contraction before and after applying each brace were recorded and analyzed. RESULTS The mean amplitudes of the focal cylindrical brace and broad pneumatic brace were reduced significantly compared to no brace (p<0.05), with a larger reduction for the cylindrical brace than the pneumatic brace (p<0.05). There was no significant difference between the proximal and distal mean amplitudes with each brace. CONCLUSION A cylindrical type brace decreased electromyographic activity in the wrist extensor more effectively than did the pneumatic type brace.

Abstract
This article reports the complication (lateral collateral ligament rupture) arising from improper numbers of steroids injections for the chronic lateral elbow pain (tennis elbow). Clinical sign and investigation with MRI confirmed a diagnosis of LCL rupture. In the present report, we describe the successful outcome of one year results in surgical debridement and lateral collateral ligament (LCL) reconstruction. A discussion of the proper conservative role for the chronic lateral epicondyalgia and the surgical decision to resolve this complication is also included.

Abstract
In addition to the routine therapy, the patients with lateral epicondylitis included into experimental group were subjected to a 12-week cell-stimulation therapy with low-intensity frequency-modulated electric current. The control group received the same routine therapy and sham stimulation (the therapeutic apparatus was not energized). The efficiency of this microcurrent therapy was estimated by comparing medical indices before therapy and at the end of a 12-week therapeutic course using a 10-point pain severity numeric rating scale (NRS) and Roles-Maudsley pain score. The study revealed high therapeutic efficiency of cell-stimulation with low-intensity electric current resulting probably from up-regulation of intracellular transmitters, interleukins, and prostaglandins playing the key role in the regulation of inflammation.

Lateral epicondylitis and beyond: imaging of lateral elbow pain with clinical-radiologic correlation. Skeletal Radiol 2012; 41:369-86.

Abstract
The diagnosis of lateral epicondylitis is often straightforward and can be made on the basis of clinical findings. However, radiological assessment is valuable where the clinical picture is less clear or where symptoms are refractory to treatment. Demographics, aspects of clinical history, or certain physical signs may suggest an alternate diagnosis. Knowledge of the typical clinical presentation and imaging findings of lateral epicondylitis, in addition to other potential causes of lateral elbow pain, is necessary. These include entrapment of the posterior interosseous and lateral antebrachial cutaneous nerves, posterolateral rotatory instability, posterolateral plica syndrome, Panner's disease, osteochondritis dissecans of the capitellum, radiocapitellar overload syndrome, occult fractures and chondral-osseous impaction injuries, and radiocapitellar arthritis. Knowledge of these potential masquerades of lateral epicondylitis and their characteristic clinical and imaging features is essential for accurate diagnosis. The goal of this review is to provide an approach to the imaging of lateral elbow pain, discussing the relevant anatomy, various causes, and discriminating factors, which will allow for an accurate diagnosis.

Abstract
OBJECTIVE To investigate the use of a novel study design in analysis of bilateral elbow pain. DESIGN N of 1, two contemporary arm, open label, randomised controlled clinical trial. SETTING A clinical epidemiologist at a university hospital in Pavia, Italy. PARTICIPANTS Two elbows with epicondylitis. INTERVENTIONS Autologous platelet lysate versus "wait and see" strategy. MAIN OUTCOME MEASURES Visual analogue scale for pain on elbow extension and resisted wrist extension. RESULTS Over six months' follow-up, the patient experienced bilateral improvement in pain, but higher in the treated arm, with a drop in visual analogue scale for pain from 28 to 4 for right (control) arm (drop of 24 points) and from 67 to 10.5 for left (treated) arm (drop of 56.5 points). CONCLUSIONS Platelet lysate might (or might not) work. Competing interests and lack of blinding might be relevant issues in the interpretation of trial results. However, the new study design can be applied to a number of conditions such as bilateral sport or trauma injuries, bilateral otitis, or any condition affecting chiral organs or limbs.

Abstract
BACKGROUND Chronic tennis elbow (lateral epicondylosis) is a common disorder. Like other chronic soft-tissue pain conditions it is often difficult to treat successfully. The effects of exercise have been discussed, but no convincing evidence has been put forward so far, and a simple protocol for exercise is lacking. AIMS OF THE STUDY This study is a randomized, controlled, clinical trial of the effect of exercise versus expectation (wait-list) on pain, muscle strength, function, and quality of life in patients with long-standing lateral epicondylosis. METHODS Eighty-one subjects with tennis elbow lasting for more than 3 months were randomly allocated to an exercise group (n = 40) or a reference group (n = 41). The exercise group performed daily exercise, with weekly load increase, for 3 months. The reference group was wait-listed, but otherwise followed in the same way. Outcome measures were pain during maximum voluntary muscle contraction (Cozen's test) and pain during maximum muscle elongation with a load (modified Empty-can-test); muscle strength was measured with a Chatillon MSE 100 hand-held dynamometer, and the Disability of the Arm, Shoulder and Hand (DASH) and the Gothenburg Quality of Life questionnaires. RESULTS The exercise group had greater and faster regression of pain, both during muscle contraction and muscle elongation, than the reference group (p = 0.0005 and p = 0.0016, respectively). There was a non-significant muscle strength difference between the groups, but no differences regarding DASH scores or quality of life measures. CONCLUSIONS Exercise appears to be superior to expectation in reducing pain in chronic lateral epicondylosis.

Abstract
There is still some disagreement about which anatomical structures are involved in tennis elbow pain, as well as its pathomechanics. In many papers attempting to explain the tennis elbow pathomechanics, most often the authors would point out to degenerative changes (of various background), which could be inflammatory in nature only initially. It is believed that the chronic patients are the most problematic cases, the origin of their ailment probably caused by many factors.

Abstract
INTRODUCTION Open surgical release remains the gold standard for treatment of recalcitrant lateral epicondylitis (tennis elbow). We aimed to evaluate the potential impact of perioperative factors on outcome after open surgical release for tennis elbow. METHODS All patients without elbow dislocation who underwent open surgical release for tennis elbow from January 2000 to June 2006 were included in the study. Comorbidities and associated pathologies of the upper limb as well as postoperative pain score, range of motion, evidence of instability, recurrence and other complications were noted. RESULTS There were 37 female and 24 male patients aged 22-60 (44.95 +/- 7.34) years. Five (8.1 percent) patients had diabetes mellitus. The mean duration of symptoms before surgery was 16.8 +/- 15.3 (range 2-84) months. The average duration of follow-up was 23.0 +/- 34.5 (range 0.4-206) months. Overall, 59 (96.7 percent) patients reported improvement of symptoms post surgery. Median grip strength on the operated and unoperated sides were 25.5 +/- 9.0 (range 10.5-44.0) KgN and 23.7 +/- 9.1 (range 9.3-41.5) KgN, respectively. Patients with diabetes mellitus had significantly higher pain scores (2.80 versus 0.36, p-value less than 0.01, 95 percent confidence interval [CI] 1.2-3.7), reduced grip strength (0.91 KgN versus 1.06 KgN, p-value is 0.038, 95 percent CI 0.29-0.01) and higher recurrence rates (40 percent versus 7.7 percent, p-value is 0.018). CONCLUSION Diabetes mellitus has a negative effect on surgical outcome in terms of pain scores, grip strength ratio and recurrence rate. This should be reiterated during preoperative counselling.

Abstract
BACKGROUND This review examines the evidence for an association between computer work and neck and upper extremity disorders (except carpal tunnel syndrome). METHODS A systematic critical review of studies of computer work and musculoskeletal disorders verified by a physical examination was performed. RESULTS A total of 22 studies (26 articles) fulfilled the inclusion criteria. Results show limited evidence for a causal relationship between computer work per se, computer mouse and keyboard time related to a diagnosis of wrist tendonitis, and for an association between computer mouse time and forearm disorders. Limited evidence was also found for a causal relationship between computer work per se and computer mouse time related to tension neck syndrome, but the evidence for keyboard time was insufficient. Insufficient evidence was found for an association between other musculoskeletal diagnoses of the neck and upper extremities, including shoulder tendonitis and epicondylitis, and any aspect of computer work. CONCLUSIONS There is limited epidemiological evidence for an association between aspects of computer work and some of the clinical diagnoses studied. None of the evidence was considered as moderate or strong and there is a need for more and better documentation.

Abstract
Pain and disability in the elbow are not as common as in the neck, shoulder or wrist, for example. The elbow may, however, present disorders that may in a prolonged state be difficult and cause significant loss of working capacity. These include epicondylitis, osteoarthritis and entrapment of the ulnar nerve.

Abstract
All cases of lateral epicondylitis surgically treated in Dr. Pruzansky's office practice between October 1986 and December 2005 yielded 24 elbows for this study. Patients were treated with surgical débridement and direct repair to bone through bone tunnels (18 elbows), repair with suture anchors (3 elbows), or augmentation with autologous tendon graft and reattachment to bone via suture anchors (3 elbows). This series represents the earliest reattachment cases to be reported, and with the longest follow-up. Mean follow-up (both telephone and office interviews) was 64.7 months. All patients reported satisfaction and graded their outcomes as good or excellent. Mean time to full painless preinjury level of use of the elbow was 4.3 months for patients who underwent simple repair and 2.75 months for patients repaired with a graft. Surgical reattachment of the débrided extensor tendon of origin of the elbow to bone, either directly or with autologous tendon graft, provided pain relief and return to preinjury level of function in a predictable manner. Both primary repair and tendon graft procedures can be used in primary and salvage surgeries in tennis elbow cases in which conservative treatment fails.
