The purpose of this study was to investigate the most effective and comprehensible method for the assessment of resting scapular position (RSP) and pain level (PL) in unilateral shoulder pain (USP). Fifty volunteers with USP were involved in the study. Resting scapular assessments of the patients' pain sides (PS) and non-pain sides (NPS) were evaluated. The assessment tools for RSP are: 1) sternal notch (SN) to coracoid process (CP) distance 2) 3rd thoracic spinous process (T3S) to posterolateral angle of acromion (PLA) distance 3) scapular index 4) 8th thoracic spinous process (T8S) to inferior angle of scapular (IAS) distance 5) supine measurement of pectoralis minor (PM) distance 6) standing PM distance 7) PM index (PMI) and 8) PM pain. The paired t-test was used to compare PS and NPS in RSP. Pearson correlation analysis was used to confer a relationship between the PL and RSP. The results of this study indicated that: 1) all the variables between the PS and NPS for RSP were statistically significant(p<.05) and 2) the PMI showed the strongest relationship in the correlation analysis between RSP and PL(p<.05, r=.37). Therefore, it can be concluded that there is a relationship between PMI and PL and it is suggested that an assessment tool using PMI to diagnose shoulder pain would be clinically effective.

Background During breast augmentation, the transaxillary approach provides the advantage of allowing the mammary prosthesis to be placed through incisions that are remote from the breast itself, thereby reducing the visibility of postoperative scars. For patients experiencing capsular contracture who do not want additional scars, the previous transaxillary scar can be used for site change and implant exchange. Methods This study analyzed 17 patients (34 breasts) with submuscular breast implants with grade III-IV capsular contracture who received treatment from 2010 to 2015. The mean age of the patients was 29 years (range, 20-38 years). The inclusion criterion was a pinch test of more than 3 cm at the upper pole of the breast. Previous axillary scars were used to expose the pectoralis fascia, and submuscular breast implants were removed carefully. The dissection underneath the pectoralis fascia was performed with endoscopic assistance, using electrocautery under direct visualization. Results The mean follow-up period was 14 months (range, 6-24 months). The entire dissection plane was changed from the submuscular plane to the subfascial plane. Round textured gel implants were used, with a mean implant size of 220 mL (range, 160-300 mL). Two patients developed grade II capsular contracture. There were no cases of malposition or asymmetry. Three patients complained of minor implant palpability. None of the patients required additional surgery. Conclusions Endoscopic subfascial conversion may be an effective technique for treating capsular contracture and avoiding scarring of the breast in selected patients.

The pectoralis major myocutaneous flap represents a major contribution to head and neck cancer reconstruction. Its advantages are improved viability, one-stage reconstruction, and carotid protection. The oropharyngeal defect especially tonsillar area reveals valley shaped one with loss of a wide mucosal area. Using pectoralis major myocutaneous flap to this defect is sometimes difficult due to its natural figure of bulkiness. This article reviews our experience with patients undergoing 14 pectoralis major myocutaneous flap in carcinoma of the tonsillar area. Complications and their incidences were I total loss, 3 marginal loss, 2 minor seperation of suture, I wound infection and 2 hematoma. Most of the complications did not require a second procedure for reconstruction. Bulkiness of the flap and gravity force to the upper suture line were thought to be causes of the complications. Modification of the flap design with bilobular figure was useful to reduce its bulkiness at the folding area. More stable suture around hard palate was needed to overcome seperation of the suture.

Objectives : This study was performed to understand the interrelation between 'Foot three yang meridian-muscle' and 'muscular system'. Methods : We have researched some of the literatures on Meridian-muscle theory, anatomical muscular system, myofascial pain syndrome and anatomy trains. And especially we have compared myofascial pain syndrome to anatomy trains and researched what kind of relationship is exist between them. Results : It is considered that Foot taeyang meridian-muscle includes Abductor digiti minimi m., Gastrocnemius m., Biceps femoris m., Longissimus m., Omohyoid m., Occipital m., Frontal m., Orbicularis oculi m., Trapezius m., Sternocleidomastoid m., Sternohyoid m., Zygomaticus m. Foot soyang meridian-muscle includes Dorsal interosseus m., Tendon of extensor digitorum longus m., Extensor digitorum longus m., Iliotibial band, Vastus lateralis m., Piriformis m., Tensor fasciae latae m., Internal abdominal oblique m., External abdominal oblique m,, Internal intercostal m., External intercostal m., Pectoralis major m., Sternocleidomastoid m., Posterior auricular m., Temporal m., Masseter m., Orbicularis oculi m. Foot yangmyung meridian-muscle includes Extensor digitorum longus m., Vastus lateralis m., Iliotibial band, Iliopsoas m., Anterior tibial m., Rectus femoris m., Sartorius m., Rectus abdominis m., Pectoralis major m., Internal intercostal m., External intercostal m., Sternocleidomastoid m., Masseter m., Levator labii superioris m., Zygomatic major m., Zygomatic minor m., Orbicularis oculi m., Buccinator m. and the symptoms of Foot three yang meridian-muscle are similar to the myofascial pain syndrome. Superficial back line in anatomy trains is similar to the pathway of Foot taeyang meridian-muscle. Lateral Line in anatomy trains is similar to the pathway of Foot soyang meridian-muscle. Superficial Front Arm Line in anatomy trains is similar to the pathway of Foot yangmyung meridian-muscle. Conclusions : There is some difference between myofascial pain syndrome and meridian-muscle theory in that the former explains each muscle individually, while the latter classifies muscular system in the view of integrated organism. More studies are needed in anatomy and physiology to support the integration of muscular system of Foot three yang meridian-muscle in aspect of anatomy trains.

This study was to investigate the difference of muscle activities in trunk, upper arm, and shoulder during push-up exercise based on 3 types of different arm position(posterior position, PP; normal position, NP; and anterior position, AP) and to provide effective push-up arm position for each muscle development. Fifteen healthy males(age, $21.5{\pm}0.5years$; height, $172.7{\pm}1.0cm$; body mass, $70.5{\pm}1.3kg$; shoulder width, $42.3{\pm}0.6cm$; and BMI, $23.6{\pm}0.5kg/m^2$) participated in this study. PP, NP, and AP of the arm were used to conduct push-up exercise and 8 muscles(deltoideus p. acromialis: DA; pectoralis minor: PMI; pectoralis major: PMA; serratus anterior: SA; biceps brachii: BB; triceps brachii: TB; latissimus dorsi: LD; and infraspinatus: IS) of right side were selected to measure muscle activities. Total 9 counts of push-up exercise were conducted and EMG data signals of 5-time(from $3^{th}$ to $7^{th}$) push-up movement were used for measuring muscle activities. PP push-up exercise showed that there was a significantly higher muscle activity of DA, PMI, PMA, SA, BB, LD, and IS(p<.05) and AP push-up exercise showed a significantly higher TB activity(p<.05). It would be suggested that different arm position evokes various muscle activities when conducting push-up exercise. PP would be the best push-up arm position for inducing various trunk, upper arm, and shoulder muscle activities compared to NP and AP.

Objective: The purpose of this study was to determine the normal morphometric landmarks of the uniting and dividing points of the brachial plexus (BP) in the periclavicular region to provide useful guidance in surgery of BP injuries. Methods: A total of 20 brachial plexuses were obtained from 10 adult, formalin-fixed cadavers. Distances were measured on the basis of the Chassaignac tubercle (CT), and the most lateral margin of the BP (LMBP) crossing the superior and inferior edge of the clavicle. Results: LMBP was located within 25 mm medially from the midpoint in all subjects. In the supraclavicular region, the upper trunk uniting at 21$\pm$7 mm from the CT, separating into divisions at 42$\pm$5 mm from the CT, and dividing at 19$\pm$4 mm from the LMBP crossing the superior edge of the clavicle. In the infraclavicular region, the distance from the inferior edge of the clavicle to the musculocutaneous nerve (MCN) origin was 49$\pm$12 mm, to the median nerve origin 57$\pm$7 mm, and the ulnar nerve origin 48$\pm$6 mm. From the lateral margin of the pectoralis minor to the MCN origin the distance averaged 3.3$\pm$10 mm. Mean diameter of the MCN was 4.3$\pm$1.1 mm (range, 2.5-6.0) in males (n = 6), and 3.1$\pm$1.5 mm (range, 1.6-4.0) in females (n = 4). Conclusion: We hope these data will aid in understanding the anatomy of the BP and in planning surgical treatment in BP injuries.

Deep pectoral myopathy (DPM), also known as Oregon muscle disease or green muscle disease, was first described in 1968 by Dickinson et al as "degenerative myopathy" in turkeys. Even though this condition was first recognized in adult meat-type turkey and chicken breeders, it is becoming more and more common in meat-type growing birds. DPM occurs exclusively in birds that have been specially selected for breast muscle development. It is generally recognized that DPM is an ischemic necrosis that develops in the deep pectoral muscle (supracoracoideus or pectoralis minor muscle) mainly because this muscle is surrounded by inelastic fascia and the sternum, which do not allow the muscle mass to swell in response to the physiological changes occurring when muscle are exercised, as in wing flapping. The lesion does not impair the general health of birds and is generally found during cut-up and deboning, moreover, it can be both unilateral or bilateral, affecting just one or both pectoralis minor muscle, respectively. No public health significance is associated to DPM, but it is aesthetically undesirable. The fillet should be removed, whereas the rest of the carcass is still fit for human consumption. However, the required trimming operations determine the downgrading of the products and produce an economic loss for the industry, especially because it affects the more valuable part of the carcass. The incidence of DPM increases with market weight in broilers, with more cases reported in higher-yielding strains and in males. Increased bird activity (flock nervousness, flightiness, struggle, and wing flapping) induced by factors such as feed or water outages, lighting programs and intensity, human activity, and excessive noises in and around chicken houses should be looked at as a trigger for the development of DPM in broiler. However, most of the studies conducted to evaluate the incidence of DPM in poultry are concerned with parental commercial breeding stocks under experimental conditions (Bianchi et al. 2006. Poult Sci 85 : 1843-1846). There is a possible genetic relationship between the selection for large-breasted birds and this condition. Management procedures that discourage excessive wing flapping would reduce the incidence (Jordan and Pattison. 1998. Poultry diseases. 398-399).

The purpose of this study was to analyze the effects of computer game usage time on trunk muscle thickness and pressure pain threshold. The 33 study participants were divided into Group A, which spent less than 10 hours per week playing computer games; Group B, which spent between 10 and 20 hours per week playing computer games; and Group C, which spent more than 20 hours per a week playing computer games. The thickness of the participants' upper trapezius (UT), pectoralis minor (PM), anterior scalene (AS), and middle scalene (MS) muscles as well as the pressure pain threshold of their UT, PM, AS, MS, and levator scapular (LS) were measured. The study found that the PM, AS, and MS muscle thickness in group C was significantly greater than in the other groups (p<.05), and the UT, AS, PM, and LS pressure pain threshold in group C was significantly lower than in other groups (p<.05). Therefore, those who use computers for a long period of time during the week should recognize that their computer usage may cause musculoskeletal disorders.
