The objective of this study is to analyze the effect of shoulder hyperabduction position during early cocking phase in association with surgical risk and performance in professional baseball players. Methods: From 2009 to 2013, total of 93 candidates reached minimum inning qualification. After exclusion criteria (overlapped players, foreign players, age over 31 years, proceed to other league and retirement), 19 players were analyzed with slow-motion pitching video for hyperabduction of the shoulder and hyperpronation of forearm in cocking-phase. Also players were analyzed with innings pitched, earned run average (ERA), walks and hits divided by innings pitched (WHIP) and surgical history with database offered by official Korean Baseball Organization website. Results: Out of total 19 players, nine players had hyperabduction arm movement and 10 players did not. Group with hyperabduction had average age of 24.3 years old, average inning/ERA/WHIP for 5 years were 55 innings/yr, 6.52 ERA/yr and 1.33 WHIP/yr, respectively, and seven players (77%) had surgeries eventually. Group without hyperabduction arm movement had average age of 25.4 years old; average inning, ERA/WHIP for 5 years were 127 1/3 innings/yr, 4.84 ERA/yr, and 1.32 WHIP/yr, respectively and five players (50%) went for surgeries. Player performance (ERA, p=0.66; WHIP, p=0.14) was not statistically influenced by the certain arm position at cocking phase but average inning pitched was statistically affected (p<0.01). Conclusion: Hyperabduction of shoulder in early cocking phase of throwing motion does not lead to decrease in performance (ERA, WHIP) but will result in tremendous decline of average IP. Also, risk of surgery is not associated to hyperabduction motion of the shoulder.","PeriodicalId":93679,"journal":{"name":"Taehan Sup'och'u Uihakhoe chi = The Korean journal of sports medicine","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86128457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to verify the incidence of scapular dyskinesis following anatomically reduced clavicle fracture and to verify the usefulness of low-dose three-dimensional (3D) scapular wing computed tomography (3D-scapula wing-CT) analysis. Methods: Twenty-four patients with mid-clavicle fracture and four patients with distal clavicle fracture were recruited. After anatomical reduction and bony union, scapular dyskinesis was assessed by history taking and physical examination by two orthopedic doctors. The mean follow-up period for the assessment was 14.3±10.1 months. Low-dose 3D-scapular wing-CT analysis in prone position was performed with calculated effective dose 2.35 mSv, which means approximately 25% dose of conventional setting. Four observers evaluated five angles (upward rotation, internal rotation, anterior tilting, superior translation, protraction) from 3D-reconstructed images on both shoulders of a patient. Authors analyzed the results between injured to normal shoulder. Results: Scapular dyskinesis or significant shortening of injured clavicle (mean clavicle length difference, − 1.77±6.36 mm) were not observed among the included 28 subjects. The difference values of the five angles between the fractured side and normal side showed no statistical significance (upward rotation: 1.51, p=0.13; superior translation: 0.89, p=0.327; anterior tilting: 1.7, p=0.096; protraction: 0.83, p=0.374; internal rotation: 0.98, p=0.406). As the interclass correlation coefficients of four observers was 0.988 (p=0.00), images from low-dose 3D-wing-CT are clear enough to assess scapular dyskinesis (interclass correlation coefficient, 0.996; p=0.00). Conclusion: It is important to make anatomical reduction and length restoration of clavicle fracture for preventing scapular dyskinesis. Low-dose 3D-scapular wing-CT is an effective tool for assessing scapular dyskinesis, which provides images of sufficient quality with little increase in morbidity from radiation hazard.","PeriodicalId":93679,"journal":{"name":"Taehan Sup'och'u Uihakhoe chi = The Korean journal of sports medicine","volume":"61 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5763/kjsm.2019.37.4.149","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72530391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: The subjects of this study were 40 middle-aged women in their 40s with metabolic syndrome but no specific disease. The exercise group performed aerobic exercise and resistance exercise five times a week for 12 weeks, and then measured body composition, blood pressure, vascular function-related inflammation factors, metabolic syndrome factors, carotid intima-media thickness, and physical factors. Results: The exercise group showed a significant (p < 0.05) reduction after exercise in all items related to body composition, systolic and diastolic blood pressure, and intima-media thickness of the right carotid and left carotid arteries. Exercise group showed a significant decrease (p < 0.05) after exercise in interleukin-6, tumor necrosis factor- α , leptin, and all items of glucose metabolism-related variables. The exercise group showed a significant (p < 0.05) increase after exercise physical efficiency index, grip strength, sit-ups, and sit & reach. After 12 weeks of exercise training, the reduction of intima-media thickness of the carotid artery was significantly (p < 0.05) correlated with the improvement of body weight, systolic and diastolic blood pressure, grip and sit & reach, blood HbA1c, and triglyceride concentration.

Methods: A total of 20 patients (mean age, 62.1 years) were included and all patients had significant traumatic events mean 3.7 weeks prior to the surgery. Preoperative acromiohumeral distance (AHD, mean 3.2 mm) and arthritis change were analyzed on plain radiograph and magnetic resonance imaging was evaluated for the nature and extent of torn tendon, and fatty degeneration (FD) of all cuff muscles to validate if the tears were traumatic or chronic. Results: Complete repairs were achieved in 15 patients and partial repair including posterior cuff in five. Functional and radiographic results were statistically evaluated and repair integrities were assessed with ultrasound at average 17.3 months. Overall functional outcome scores were significantly improved and 17 patients (85%) were satisfied with their symptoms. AHD was significantly recovered (mean, 6.7 mm), but two patients showed progression of arthritic change. Retears after the complete repair were three patients (20%), who showed poor outcome, with advanced preoperative FD of posterior cuff muscles. Five patients with partial repair of posterior cuff revealed improved functional score with no sign of retear of posterior cuff on ultrasound. Conclusion: Early recognition of traumatic superimposed posterior cuff tears and surgical repair can reliably restore shoulder function, and partial repair of posterior cuff also can be expected favorable outcomes in supraspinatus tear with advanced FD.","PeriodicalId":93679,"journal":{"name":"Taehan Sup'och'u Uihakhoe chi = The Korean journal of sports medicine","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77573819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it remains unclear whether IHE is similar benefits on arterial stiffness and endothelial function compared with aerobic exercise (AE) in elderly hypertensive patients. The aim of this study was to compare the effects of IHE versus AE on arterial stiffness and endothelial function in elderly hypertensive patients. Methods: We conducted a randomized controlled trial with a three-arm design. Fifty-four elderly hypertensive patients (15 men; mean age, 69±6 years; systolic blood pressure, 131.2±14.7; diastolic blood pressure, 80.2±7.9 mm Hg) were randomized to IHE training (n=18), AE training (n=21), or non-exercise control group (n=21) for 12 weeks. Bilateral IHE training was performed four times of 2 minutes at 30% of maximal voluntary contraction with three times per week. AE training was performed brisk walking for 30 minutes at moderate intensity with three times per week. Carotid-femoral pulse wave velocity (PWV), augmentation index heart rate corrected (AIx@75 bpm) and brachial artery flow-mediated vasodilation (FMD) as indices of arterial stiffness and endothelial function were measured at baseline and after the intervention. Results: Following 12-week intervention, resting BP was significantly decreased in both IHE (p=0.001) and AE groups (p=0.002). AIx@75 bpm and FMD were unchanged in the all groups. However, PWV was significantly decreased in both IHE and AE groups (IHE, 10.9±2.3 to 9.9±2.1 m/s [p<0.001]; AE, 10.5±2.0 to 9.4±1.6 m/s [p=0.001]), without any change in the control group.
