Objective: The purpose of this study was to investigate the differences in static arch height and ankle stability according to the preference for insole height and hardness in the arch area. Method: The study participants were 20 adult males (age: 22.7 ± 1.8 yrs., height: 175.3 ± 4.3 cm, body weight: 72.5 ± 7.7 kg). First, the arch heights of all subjects were measured in static postures (sitting and standing). The inversion and eversion movements of the ankle joint were analyzed during walking (1.3 m/s & 1.7 m/s) and running (2.7 m/s & 3.3 m/s). The variables (static arch height, and inversion and eversion angle of ankle joint) were compared by classifying groups according to the preference for the height and hardness of the arch of the insole. First, it was divided into a high arch insole preference group (HAG, n=8) and a low arch insole preference group (LAG, n=12) according to the preference for the arch height of the insole. Second, it was divided into a high hardness insole preference group (HHG, n=7), medium hardness insole preference group (MHG, n=7), and low hardness insole preference group (LHG, n=6), according to the preference for the arch hardness of the insole. Results: First, the range of motion (ROM) of inversion-eversion at the ankle joint during walking was statistically smaller in HAG than in LAG (p<.05). Second, the arch height change of HHG was statistically greater than that of MHG and LHG (p<.05). Conclusion: In the case of flexible flat feet with a large change in arch height, providing a high hardness arch insole that can disperse foot pressure can improve comfort. It was found that people with high medial and lateral sway of the ankle joint preferred a low arch insole, but it is necessary to differentiate and compare the insole heights of the arch part in detail. In addition, in the case of fast motion such as running, the preference for the arch height and hardness of the insole was not related to the static arch height and ankle stability.

Background: To compare the clinical outcomes of arthroscopic capsular release in patients with and without inferior capsular release for shoulder stiffness. Methods: Between January 2010 and December 2015, 39 patients who underwent arthroscopic capsular release for shoulder stiffness were enrolled and randomized into two groups. In group I, 19 patients underwent arthroscopic capsular release of the rotator interval and anterior capsule. In group II, 20 patients underwent arthroscopic capsular release of the anterior to inferior capsule, including the rotator interval. The American Shoulder and Elbow Surgeons score, Constant scoring system, Simple Shoulder Test, visual analogue scale for pain, and range of motion (ROM) were used for evaluation before surgery, at 3, 6, and 12 months after surgery and on the last follow-up. Results: Preoperative demographic data revealed no significant differences (p>0.05). The average follow-up was 16.07 months. Both groups showed significantly increased ROM at the last follow-up compared with preoperative (p<0.05). At the last follow-up, no statistical differences were found (p>0.05) between groups I and II in functional scores and ROM (forward flexion, p=0.91; side external rotation, p=0.17; abduction external rotation, p=0.72; internal rotation, p=0.61). But we found that group II gained more flexion compared to group I at 3 months and 6 months (p<0.05) after the surgery. Conclusions: Both techniques of capsular release are effective for stiffness shoulder. However, the extended inferior capsular release shows superiority in forward flexion over anterior capsular release alone during 6 months of follows-up (level of evidence: Level I, therapeutic randomized controlled trial).

Background: We prospectively compared the response to blind and ultrasound-guided glenohumeral injection of corticosteroids for treatment of shoulder stiffness. Methods: A total of 77 patients with shoulder stiffness between April 2008 and March 2012 were recruited. Patients were randomized to receive either a blind (group 1, n=39) or ultrasound-guided (group 2, n=38) glenohumeral injection of 40 mg triamcinolone. The clinical outcomes and shoulder range of motion (ROM) before injection, at 3, 6, and 12 months after injection and at the last follow-up were assessed. The same rehabilitation program was applied in both groups during the follow-up period. Results: There was no significant difference in demographic data on age, sex, ROM, and symptom duration before injection between groups (p>0.05). There were no significant differences in ROM including forward flexion, external rotation at the side, external rotation at $90^{\circ}$ abduction, and internal rotation, visual analogue scale for pain and functional outcomes including American Shoulder and Elbow Surgeons score, Simple Shoulder test between the two groups at any time point (p>0.05). Conclusions: Based on the current data, the result of ultrasound-guided glenohumeral injection was not superior to that of blind injection in the treatment of shoulder stiffness. We suggest that ultrasound-guided glenohumeral injection could be performed according to the patient's compliance and the surgeon's preference. Once familiar with the non-imaging-guided glenohumeral injection, it is an efficient and reliable method for the experienced surgeon. Ultrasound could be performed according to the surgeon's preference.

Objectives : The aim of this study is to observe clinical characteristics and treatment outcomes of inpatients admitted to a Korean medicine hospital for shoulder pain based on magnetic resonance imaging(MRI) findings. Methods : 28 patients with MRI data were included. Data on MRI findings, duration of pain, and treatment effects were collected. To measure treatment outcomes, verbal numerical rating scale(VNRS), range of motion(ROM), and a clinical condition grading system were used. Results : 1. The patient population was 75.0 % female and 39.3 %(n=11) belonged to the 51~60-year-old age group. In the under 40 population, 1 or less MRI findings were found. 2. As for the type of disorder, 82.1 % of the patients were diagnosed with 'Supraspinatus lesion', 39.3 % with 'subacromial-subdeltoid(SA-SA) bursitis', and 28.6 % with 'Adhesive capsulitis' 3. Numerous correlations could be made between duration of pain and MRI findings. 'rotator cuff full thickness tear' was more prevalent in acute shoulder pain patients, and 'Adhesive capsulitis' in chronic patients. 4. VNRS and ROM at the time of discharge had significantly improved as compared to VNRS and ROM at the time of admission. 5. As for correlation between MRI findings and clinical condition grade, patients diagnosed with 'rotator cuff partial tear' reported to be in 'good' condition or better whereas those with 'rotator cuff full thickness tear' reported to be in 'fair' condition or worse. Conclusions : Patients admitted to a Korean Medicine hospital for shoulder pain had varying degrees of severity as shown on MRI. Almost all lesions responded well to Korean medicine treatment.

Purpose: Chronic tophaceous gout is a painful and disabling inflammatory disease. Surgical treatment for chronic tophaceous gout is very difficult with many complications. This study evaluated the efficacy of shortening scarf osteotomy on the treatment of chronic tophaceous gout in the 1st metatarso-phalangeal (MTP) joint. Materials and Methods: From January 2006 to December 2015, 14 patients (19 cases) who underwent axial shortening scarf osteotomy for chronic tophaceous gout were reviewed. All patients were male. The average age at the time of surgery was 59.6 years (42~66 years). The minimum follow-up was 24 months. Total removal of the tophi mass with the adhered medial capsule of the 1st MTP joint was attempted. Axial shortening scarf osteotomy was done on the 1st metatarsal shaft. The visual analogue scale (VAS) for pain and the American Orthopaedic Foot and Ankle Society (AOFAS) forefoot score was assessed preoperatively and postoperatively. The range of motion (ROM) of the 1st MTP joint was also compared pre- and postoperatively. Results: The average size of the extracted tophaceous mass was 32 mm. The mean amount of the length of metatarsal shortening was 4.9 mm. The mean ROM of the 1st MTP joint was improved from $30.4^{\circ}$ to $62.3^{\circ}$. The mean AOFAS forefoot score improved from 51.4 to 86.6 points. The mean VAS for pain improved from 4.6 to 0.3 points. Conclusion: The axial shortening scarf osteotomy used on chronic tophaceous gout could reconstruct the 1st MTP joint with an improved ROM and was free of pain. Axial shortening scarf osteotomy is suggested as a useful and effective method for the treatment of chronic tophaceous gout.

Purpose : The purpose of this study was to investigate the effect of tensor fasciae latae length on the rotation of pelvis during one leg stance. Methods : 41 healthy adults participated in this study. The movement of the pelvis and trunk was measured using 3-dimensional motion analyzer, during one leg stance. The movement of the pelvis and trunk was collected lateral shift, rotation, side bending, and flexion-extension. Tensor fasciae latae length of subjects was measured in sidelying positon with neutral position of hip joint and flexion $90^{\circ}$ of knee. Also, the range of motion of hip exteral and interal rotaion were measured in prone position wih lexion $90^{\circ}$ of knee. The subjects were separated 2 groups that more pelvic rotation group(n=15) and less pelvic rotation group(n=15) according to the degree of pelvic rotation. Results : The more pelvic rotation group was showed significantly higher in the ROM of hip external rotation than less pelvic rotation group(p<0.05). The difference of tensor fasciae latae length not showed significant difference between groups. During one leg stance, The movement of the shifting and flexion-extension of trunk and pelvis were not showed significant difference. But the side bending and the rotation of pelvis and trunk showed significant difference between groups. Conclusion : The difference of tensor fasciae latae length not showed significantly in more pelvic rotation group and less pelvic rotation group. But, this study suggests that the pelvis instability brings the instability of the trunk during one leg stance.

Objective: The purpose of this study was to investigate kinematic comparisons of Tsukahara vault in gymnastics between a top-level athlete and sublevel collegiate athletes in order to obtain information on key biomechanical points for successful Tsukahara vaults. Methods: An Olympic gold medalist (height, 160 cm; weight, 52 kg; age, 25 years) and five sublevel collegiate gymnasts (height, $168.2{\pm}3.4cm$; weight, $59.6{\pm}3.1kg$; age, $23.2{\pm}1.6years$) participated in this study. They repeatedly performed Tsukahara vaults including one somersault. Fourteen motion-capturing cameras were used to collect the trajectories of 26 body markers during Tsukahara vaults. Event time, displacement and velocity of the center of mass, joint angles, the distance between the two hands on the horse, and averaged horizontal and vertical impact forces were calculated and compared. Results: The top-level athlete showed a larger range of motion (ROM) of the hip and knee joints compared to sublevel collegiate athletes during board contact. During horse contact, the top-level athlete had a narrow distance between the two hands with extended elbows and shoulders in order to produce a strong blocking force from the horse with a shorter contact time. At the moment of horse take-off, reactive hip extension of the top-level athlete enhanced propulsive take-off velocity and hip posture during post-flight phase. Conclusion: Even though a high velocity of the center of mass is important, the posture and interactive action during horse contact is crucial to post-flight performance and the advanced performance of Tsukahara vaults.
