Professor YIN Kejing's academic thoughts and clinical experience in treating lateral epicondylitis using classical acupuncture techniques are introduced. Professor YIN Kejing believes that the onset of lateral epicondylitis is due to external pathogenic factors and internal overstrain, leading to a pathological mechanism of muscular tension, meridian obstruction, and qi-blood stasis, resulting in disharmony between nutritive qi and defensive qi. Treatment should adhere to the principles of disease pathogenesis, with meticulous diagnosis and emphasis on relaxing tendons, relieving muscular tension, dredging meridians, and regulating nutritive qi and defensive qi. Based on the theories of yin-yang balance, nutritive qi and defensive qi regulation, and the collateral connection of meridians, the treatment involves selecting positive muscular reaction points, the five-shu points of the related meridians, and collateral connection points. Classical acupuncture techniques, including floating needling, guan needling, three-needle needling, cross-needling, and through-needling, are applied to stimulate defensive qi, regulate nutritive qi, facilitate the transmission of meridian qi, and adjust tendon qi. This approach effectively relieves muscular tension, alleviates pain, restores function, and rebalances yin and yang. The treatment is characterized by precise acupoint selection, distinctive features, and remarkable efficacy.

This paper introduces Professor WANG Jihong's clinical experience in treating refractory lateral epicondylitis using the Wang's crescent technique of blade needle. Based on the classical theories of Huangdi Neijing (the Yellow Emperor's Inner Classic) such as the "twelve sinew meridians" "short needling" and "shu needling", Professor WANG applies a self-designed blade needle with crescent needling method. This approach forms a distinctive treatment philosophy characterized by "sinew meridians as the foundation, selecting points at the pain site; using chicken-claw needling technique deliverd at both internal and external; integration of heaven, earth, and man, using both short and shu needling; treating tendon injuries and inflammation with the crescent technique of blade needle". It embodies the therapeutic concept of "treating tendons and bones simultaneously, harmonizing yin and yang", and shows unique advantages in the treatment of this condition.

OBJECTIVE: To quantitatively study the biomechanical parameters of Bachuorounian manipulation in the treatment of humeral epicondylitis, and discuss the effects of individual characteristics on the biomechanical parameters were discussed. METHODS: From July 2019 to February 2020, 40 patients with external humeral epicondylitis were selected, including 18 males and 22 females, ranging in age from 20 to 50 years old, with an average of (34.37±8.41) years old;and the course of disease ranged from 1 to 11 months, with a mean of (6.05±2.71) months. The biomechanical parameters of the elbow joint of the affected side were measured by using the biomechanical sensor. At thesame time, the individual characteristic parameters of patients were collected to analyze the influence of different individual characteristics of patients on biomechanical parameters. RESULTS: The results of mechanical analysis in each stage of the bachuorounian manipulation were as follows:the rolling back rotation force was (31.17±2.99) N;the buckling bending drawing force was (44.99±2.38) N;the rolling pre rotation force was (31.03±2.75) N;and stretching drawing force was (48.75±2.09) N. The correlation analysis between the parameters showed that there was a significant positive correlation between the buckling bending drawing force and the stretching drawing force parameters, and a significant positive correlation between the rolling force back-rotation force and the rolling pre-rotation force parameters. The multivariate linear regression analysis on the parameters of influencing factors and manipulative biomechanics showed that there was a significant correlation between body weight and rolling back-rotation force, significant correlation between elbow tenderness and the buckling bending drawing force, and significant correlation between disease duration and the stretching drawing force. CONCLUSION The bachuorounian manipulation of humeral epicondylitis has a certain range of operating force. Manipulation of each stage has a correlation and systematic. The patient's weight, elbow tenderness and disease course are important factors affecting the bachuorounian manipulation.

PURPOSE: The purpose of this study was to investigate the muscle activities of the brachioradialis and extensor carpi radialis longus according to the type of backhand stroke in badminton.METHODS: To measure the muscle activities, we used electromyography (EMG) equipment to measure EMG values by performing maximal voluntary contraction (MVC) of the forearm muscles, which depends on the type of backhand stroke. With these values, the %maximum voluntary isometric contraction values were obtained. The data were calculated using SPSS ver. 21.0 and one-way repeated measures analysis of variance with a post-hoc least significant difference test.RESULTS: In this study, the backhand clear achieved higher maximum muscle activity values than those by the backhand push, under clear, and drive in the brachioradialis. The backhand smash achieved higher maximum muscle activity values than those by the backhand push in the extensor carpi radialis longus.CONCLUSION: The backhand clear is associated with a higher injury rate than those associated with the backhand push, under clear, and drive. The backhand smash is associated with a higher rate of the occurrence of tennis elbow than that associated with the backhand push. To prevent injuries, it is considered that the forearm's strength, stretching before and after exercise, and sufficient time to rest are important.

Ganglion cyst is considered to be a usual cause of peripheral nerve compression. In this report, we present a rare case of ulnar nerve compression by a multi-septated ganglion cyst in the cubital tunnel. A 33-year-old left-handed male amateur tennis player developed progressive numbness and weakness in his right elbow, forearm, and hand for 1 year. Decrease of grip power was apparent in left hand. Clinical examination revealed a cystic mass at the posterior side of the elbow. Magnetic resonance imaging identified a ganglion cyst at the elbow. During surgery about 3 cm diameter epineural ganglion was observed compressing the ulnar nerve and was excised using microsurgery techniques. Three months postoperatively, the clinical recovery of the patient was very satisfactory and he restored his original performance in tennis match.

PURPOSE: The aim of this study was to examine the prevalence of upper extremity musculoskeletal (MSK) diseases and to identify factors influencing disability among fruit tree farmers in Korea. MATERIALS AND METHODS: Of the 1150 subjects of the Namgaram study, 460 fruit tree farmers completed a questionnaire and underwent clinical evaluations, including physical assessments, laboratory tests, simple radiographic examinations, and magnetic resonance imaging studies of the upper extremities. Disability was assessed using the Disabilities of the Arm, Shoulder, and Hand outcome measure. Data were analyzed with descriptive statistics and regression analyses using SPSS Win 24.0. RESULTS: The prevalences of upper extremity MSK diseases were 60.4% for rotator cuff tear, 20.9% for golf elbow, 40.9% for tennis elbow, and 58.0% for hand osteoarthritis. Disability in fruit farmers was associated with female sex (B=−4.47, p<0.001), smoking (B=−4.00, p=0.026), depression (B=2.83, p<0.001), working hours (B=0.96, p=0.001), injuries of the arms (B=10.78, p<0.001) and shoulders (B=6.75, p<0.001), and numbers of upper extremity MSK diseases (B=2.02, p=0.001), with 26.5% of the variance explained (R2=0.265, Durbin-Watson test=1.81, p<0.001). CONCLUSION: Fruit tree farmers remain at risk for MSK diseases of the upper extremities. Disability tended to worsen with more MSK diseases. It is necessary to not only educate farmers about prevention strategies, but also to develop an effective management system for agricultural work-related MSK diseases and a surveillance system at the government level for the health problems of farmers.

Background: Lateral epicondylalgia (LE) is a cumulative strain injury affecting the common extensor origin of the elbow, manifesting as lateral elbow pain. Tightness of the fascia connecting the lateral elbow area with the shoulder area was assumed as potential source of LE. Limitation in shoulder rotatory motions may be associated with painful LE elbows. Aim: To determine the difference on shoulder rotatory motions between sides of symptomatic and asymptomatic elbows. Methods: Eligible participants had at least one elbow that tested positive for Cozen, Mill, or Maudsley’s test. Using a universal goniometer, a blinded assessor measured the participants’ active and followed by passive shoulder internal and external rotation. The primary investigator tested the external rotation followed by internal rotation of the right upper extremity, then subsequently the left upper extremity of healthy participants both passively and actively Results: The assessor showed excellent intra-tester reliability in measuring active and passive shoulder rotatory motions of 20 asymptomatic right upper extremities (ICC=0.98). Twenty-seven (27) participants (3 males, 24 females) with a mean (95%CI) age of 54 (49-58) years old were enrolled in the study. The mean visual analogue scale of the patients was 6.53 (5.91- 7.13), with mean (95%CI) duration of 96 (50-142) weeks. Based on hand dominance and side of LE, significant difference was found in active and passive shoulder internal rotation (p>0.05). Conclusion Shoulder active and passive internal rotations were significantly associated with hand dominance in patients with LE. Tightness of the fascia and muscle in the shoulder and painful LE elbow may underpin the decreased shoulder rotatory motions.

The natural course of lateral epicondylitis is widely regarded to be self-limiting within 1 year of symptom duration in 90% of all patients. The spectrum of treatments include simple ‘wait and see', bracing, physical therapy, corticosteroid injection, and recently some biologic injection such as autologous blood and platelet rich plasma. However, recalcitrant lateral epicondylitis which are not responding to conservative treatments can be treated with surgical treatment although much remains unclear regarding the ideal treatment. Debates surrounding open procedures are the management for the defect after resection of pathologic tissue, necessity of decortication, selective denervation procedure, etc. Since the trend is changing to minimal invasive surgery and arthroscopic release of extensor carpi radialis brevis tendon are becoming more popular these days, surgical tips and pitfall to obtain good results and avoid complications have been reported recently. Bipolar radiofrequency (RF)-based microtenotomy or percutaneous tendon release is another surgical procedures reported to be effective in lateral epicondylitis. However, there are some patients who present with persistent pain after surgical treatment. Thus, selection of ideal candidates for surgery, thorough evaluation of all pathologies prior to surgery, and adequate surgical procedures would be essential in the surgical treatment of lateral epicondylitis.

The purpose of this study is to clinically evaluate and report the effectiveness of radiofrequency microdebrider (Topaz, ArthroCare) treatment in lateral epicondylitis patients. From March to July 2003, 15 patients of 17 elbows were prospectively followed. Candidate for the treatment were lateral epicondylitis patients who had symptom more than 6 month and failed to respond to conservative treatment, including medication (non-steroidal anti-inflammatory drugs), external gel or patch, and steroid injections. All patient who scored greater than grade 3 (fair) on the Self-administered Roles and Maudsley Pain (SRMP) score were selected for the procedure. All procedure was done using local anesthesia and ArthroCare microdebrider by a single surgeon. Postoperative assessments were done on postoperative period 12 month of two previous subjective scores and a simple functional assessment asking better, same, or worst function after the procedure. Mean age of the patients was 45 years old. Mean symptom duration before the procedure was 22.6 months. After the procedure, the mean Pain Visual Analogue Scale improved from 7.3 (range, 5–9; standard deviation [SD], 1.2) preoperatively to 3.7 (range, 0–7; SD, 2.1) postoperatively (p< 0.001). After the procedure, five elbows showed no rating improvement, in seven elbows 1 level improvement, in four elbows 2 level improvement, and in one elbow 3 level improvement. Overall, 71% (12/17) showed improvement after the procedure according to the SRMP score rating. Although 29% (5/17) of the elbow showed no improvement on SRMP score, among them five elbows were still rated decrease in Pain Visual Analogue Scale.
