We report a case of simultaneous anterior and posterior interosseous nerve syndrome in association with shoulder arthroscopy. Shoulder arthroscopy was performed in a 45-year-old male patient with left shoulder instability. In the right lateral decubitus position, under general anesthesia, traction was applied with elbow extension for 2 hours. One week after surgery, the patient revisited the clinic for weakness of the flexor of the thumb, index finger, and extensor of the fingers. Recovery was not achieved after four months of observation. Therefore, nerve exploration was performed in the anterior and posterior interosseous nerve and hourglass-like fascicular constriction was detected in the posterior interosseous nerve. The area of constriction was removed and epineural neurorrhaphy was performed. Three months after exploration, the extension function of the fingers was recovered. Recovery was achieved gradually, and, five months after nerve exploration, the symptoms were completely recovered. Simultaneous anterior and posterior interosseous nerve syndrome following shoulder arthroscopy is rare. However, it could occur due to the traction and position of the patient. Thus, the operator should be careful of traction and position of the patient.

Purpose : This study investigated the effects of concentric and eccentric contractions on muscle strength using an isokinetic dynamometer (ID) in college students in their 20s. It aimed to understand the impact of differences between the dominant and non-dominant sides on strength asymmetry and to elucidate the clinical implications of these differences to establish an appropriate posture and environment for patients. Methods : The experiment was conducted with 30 healthy adult participants. Prior to the experiment, participants underwent a warm-up targeting the shoulders, and efforts were made to eliminate factors that could potentially influence the measurement results. Subsequently, the maximum safe range of motion of shoulder joint abduction, extension, and flexion was measured using an isokinetic muscle function testing device. Muscle strength was assessed using concentric and eccentric contractions alternating between the dominant and non-dominant sides, and paired sample t-tests were used for the analysis. Results : There was no significant difference between bilateral peak torques for eccentric contraction in shoulder joint abduction, extension, and flexion (p>0.05). There was also no significant difference between bilateral peak torques for concentric contraction in shoulder joint abduction, extension and flexion (p>0.05). Conclusion : This study found no statistically significant difference in muscle strength between the dominant and non-dominant sides during concentric and eccentric contractions. However, previous studies have shown significant differences between the dominant and non-dominant sides during eccentric and concentric contractions during internal shoulder rotation in the general population, as well as significant differences in the upper trapezius muscle. Therefore, further research is needed to support the application of different intensities for bilateral muscle strengthening exercises in clinical practice.

Background: The purpose of this study is to investigate the effect of neck and shoulder self-stretching exercise using audiovisual media on neck pain, postural alignment, and joint position error in women with chronic neck pain. Methods: The subjects included 20 women that gave consent to participate in the study voluntarily. They performed the self-stretching exercises using audiovisual media was carried out 20 minutes 5 times a week during 3 weeks. Neck disability index (NDI) and visual analogue scale (VAS) were used to measure the functional disability and pain, A pressure pain threshold was measured using an algometer, and a cervical range of motion (CROM) measurement tool was used to measure the range of motion and error of proprioceptive position sense of the cervical spine. To assess posture alignment, forward head angle (FHA), forward shoulder angle (FSA) were measured using image J software. Results: The neck pain intensity was statistically significantly within group (p<.05). Neck and shoulder functional disability were a statistically significant difference within group (p<.05). Splenius capitis and upper trapezius pressure pain threshold were statistically significant difference in within group (p<.05). The postural alignment was statistically significantly within group (p<.05). The cervical range of motion in neck extension, right and left lateral flexion were statistically significantly within group (p<.05). The joint position error in neck flexion, extension, right and left lateral flexion decreased statistically significantly within group (p<.05). Conclusion: Self-stretching exercise using audiovisual media increased the mobility of the neck, decreased neck pain and joint position error, and improved posture alignment. As a result, there was a positive effect by applying the self-stretching exercise using audiovisual media to people with neck pain. Based on this, it is thought that it can be used as the basis for research related to home training programs for healthy self-management.

Osborne-Cotterill lesion is an osteochondral fracture located in the posterolateral margin of the humeral capitellum, which may be associated with a defect of the radial head after an elbow dislocation. This lesion causes instability by affecting the lateral ulnar collateral ligament over its capitellar insertion, which is associated with a residual capsular laxity, thereby leading to poor coverage of the radial head, and hence resulting in frequent dislocations. We present a 54-year-old patient, a physician who underwent trauma of the left elbow after falling from a bike and suffered a posterior dislocation fracture of the elbow. The patient subsequently presented episodes of instability, and additional work-up studies diagnosed the occurrence of Osborne-Cotterill lesion. An open reduction and internal fixation of the bony lesion was performed, with reinsertion of the lateral ligamentous complex. Three months after surgery, the patient was asymptomatic, having a flexion of 130° and extension of 0°, and resumed his daily activities without any limitation. Currently, the patient remains asymptomatic 2 years after the procedure. Elbow instability includes a large spectrum of pathological conditions that affect the biomechanics of the joint. The Osborne-Cotterill lesion is one among these conditions. It is a pathology that is often forgotten and easily overlooked. Undoubtedly, this lesion requires surgical intervention.

This study is analyzing about application of taping by movement about shoulder joint's isometric contraction. M. college students take part in experiment. WEMG-8 and HUMAC system are used. Findings were as follows: EMG of muscle's MVIC at each angle before and after taping. 1. In flexion, EMG with taping is effective for supra spinatus at $0^{\circ}{\cdot}45^{\circ}{\cdot}90^{\circ}$, anterior deltoid at $0^{\circ}{\cdot}45^{\circ}$ and biceps brachii at $0^{\circ}{\cdot}90^{\circ}$. 2. In extension, EMG with taping is effective for triceps brachii at $0^{\circ}$, latissimus dorsi at $90^{\circ}$ and posterior deltoid at $45^{\circ}{\cdot}90^{\circ}$. 3. Each angle viewpoint, EMG of latissimus dorsi in extension can be arranged in its high order as $90^{\circ}<45^{\circ}$, $0^{\circ}$ without taping and $90^{\circ}<0^{\circ}$ respectively. EMG of posterior deltoid in extension is in its high order as $90^{\circ}<45^{\circ}<0^{\circ}$ without taping and $90^{\circ}<0^{\circ}$.

The purpose of this study was to quantitatively investigate the effects of external load upper extremity posture on perceived discomfort. An experiment was conducted for measuring discomfort scores depending upon external loads and upper extremity postures, in which the free modules and numeric estimate method of the magnitude estimation was adopted as a tool for obtaining discomfort ratings. The upper extremity postures were controlled by wrist flexion/extension, elbow foexion, shoulder flexion, and shoulder adduction/abduction. The results showed that all experimental variables except shoulder adduction/abduction were significant at ${\alpha}$=0.01 or 0.05. The effect of external load was very much larger than that of upper extremity postures. Therefore, it is recommended that a new posture classification scheme taking effect of external load to into consideration be developed for quantifying postural load.

Background: The purpose of this study is to administer conservative treatment in 30 patients diagnosed with idiopathic frozen shoulder, following the suggested frozen shoulder rehabilitation program and to assess the clinical outcome using a prospective study. Methods: Thirty patients diagnosed with idiopathic frozen shoulder, treated with steroid hormone injection on the articular joint with an intra-articular steroid (triamcinolone 40 mg+lidocaine 4 ml) injection and started on stepwise shoulder extension exercise were chosen. The subjects were divided into two groups of 15 people each with one group undergoing rehabilitation with continuous passive motion (CPM) and the other group without it. Follow-ups were done before rehabilitation and at 4-week intervals with the 24th being the final week. At every follow-up, passive range of motion (ROM) was measured and surveys on pain and clinical score were administered. Results: In the last follow-up, both groups showed statistically significant improvements in all evaluation criteria. However, no statistical difference in all values of the ROM and Constant score evaluation criteria was observed between the groups. Only in the last follow-up, group 1 had a visual analog scale (VAS) score of $2.4{\pm}2.1$ points, which was lower, with statistical significance, than the VAS score of group 2, which was $4.4{\pm}3.1$ points (p<0.001). Conclusions: Study using CPM in treatment of frozen shoulder has been inadequate, meaning that there is still room for improvement and need for more study on setting a more specific protocol and guidelines for this procedure.

Objectives : The purpose of this research was to study the effect of Scolopendrid Pharmacopuncture on frozen shoulder patients. Methods : All of the 46 frozen shoulder patients who visited the department of Acupuncture & Moxibustion in Wonkwang Sanbon Medical Center from 1st March 2007 to 30th August 2008 had taken either the Scolopendrid Pharmacopuncture therapy or acupuncture therapy 10 times. There are 23 patients in each group. We evaluated the improvement of their shoulder pain and disability using the Visual Analog Scale(VAS), Shoulder Pain And Diability Index(SPADI), Range of Motion(ROM), and the Apley Scratch test at their first and last visit. Then we analyzed and compared the improvement shown by the two groups. Results : 1. Measures on all tests for the acupuncture group showed statistically significant improvement. 2. Measures on all tests for Scolopendrid Pharmacopuncture showed statistically significant improvement. 3. The Scolopendrid Pharmacopuncture group's VAS and ROM(external, internal rotation) showed statistically significant difference compared with those of the acupuncture group. SPADI, ROM(flexion, extension, abduction, adduction) and Apley scratch test had no statistically significant difference between the two groups. Conclusions : The above results show that Scolopendrid Pharmacopuncture therapy can be used as an effective treatment for reducing frozen shoulder pain.
