Purpose: The aim of this study was to investigate the relationship between a functional evaluation model and the Fugl-Meyer assessment (FMA) scale in evaluating the upper extremities of stroke patients Methods: Thirty-eight stroke patients were evaluated using the FMA and performed reaching and grasping motions using a three-dimensional motion analysis (Qquas 1 series, Qualisys AB, Sweden). The participants sat on a chair with a backrest. The position of the cup was located at a distance of 80% to the front arm length. The markers were attached to the sternum, acromion, elbow lateral epicondyle, ulnar styloid process, three metacarpal heads, and the distal phalanges of the thumb and index finger. The variables of the correlation between the functional evaluation model and the FMA scale were analyzed. Multiple regression (stepwise) was used to investigate the effect of the kinematic variables. Results: A significant negative correlation was found between the movement time (p < 0.05), movement unit (p < 0.05), and trunk displacement values (p < 0.05) in the FMA total scores, while a positive correlation was found between the peak velocity (p < 0.05) and maximum grip aperture values (p < 0.05). As a result of the multiple regression analysis, the most significant factor was the movement unit, followed by the general movement assessment and trunk displacement. The explained FMA total score value was 62%. Conclusion: This study presents a new functional evaluation model for assessing the reaching and grasping ability of stroke patients. The factors of the proposed functional evaluation model showed significant correlations with the FMA scale scores and confirmed that the new functional evaluation model explained the FMA by 67%. This suggests a new functional evaluation model for reaching and grasping stroke patients.

Background: To evaluate clinical and radiological outcomes of bony increased offset-reverse total shoulder arthroplasty (BIO-RSA) in the Asian population at mid-term follow-up. Methods: From June 2012 to August 2017 at a single center, 43 patients underwent BIO-RSA, and 38 patients with minimum 2 years follow-up were enrolled. We evaluated the clinical and radiological outcomes, and complications at the last follow-up. In addition, we divided these patients into notching and no-notching groups and compared the demographics, preoperative, and postoperative characteristics of patients. Results: Visual analogue scale, American Shoulder and Elbow Surgeons, University of California-Los Angeles Shoulder Scale, and Simple Shoulder Test scores improved significantly from preoperative (5.00, 3.93, 1.72, 3.94) to postoperative (1.72, 78.91, 28.34, 7.66) (p<0.05) outcomes. All range of motion except internal rotation improved significantly at the final follow-up (p<0.05), and the bone graft was well-incorporated with the native glenoid in all patients (100%). However, scapular notching was observed in 20 of 38 patients (53%). In the comparison between notching and no-notching groups (18 vs. 20 patients), there were no significant differences in demographics, radiological parameters, and clinical outcomes except acromion-greater tuberosity (AT) distance (p=0.003). Intraoperative complications included three metaphyseal fractures and one inferior screw malposition. Postoperative complications included ectopic ossification, scapular neck stress fracture, humeral stem relaxation, and late infection in one case each. Conclusions: BIO-RSA showed improved clinical outcomes at mid-term follow-up in Asian population. However, we observed higher scapular notching compared to the previous studies. In addition, adequate glenoid lateralization with appropriate humeral lengthening (AT distance) might reduce scapular notching.

The anatomical structure of the Skeleton of thoracic limb of thirty-one adult Korean native goats(body weight: 14~17kg) was observed after skeletal preparation, and the osteometry was performed in each bone. The results were as follows; 1. The thoracic limb of the Korean native goat was composed of scapula, humerus, radius, ulna, carpal bones, metacarpal bones, phalanges and sesamoid bones. 2. The scapula was flat and triangular in shape. There were no distinct tuber of spine and acromion in the spine. The subscapular fossa was deep and triangular in shape and the vertebral border was sigmoid form. The coracoid bone was formed as the coracoid process at the medial aspect of the supraglenoid tubercle but the clavicle wa.s not observed. The left and right scapular indexes were 57.92 and 58.31 and the glenoid cavity indexes were 89.23 and 86.82, respectively. 3. The greater tubercle of the humerus was devided into cranial and caudal parts. The third tubercle was observed and the face for the infraspinatus muscle was rectangular form. The left and right humerus indexes were 32.44 and 32.63, the head indexes were 94.13, 96.62 and the trochlear-epidondyle indexes were 67.32 and 65.81, respectively. 4. The radius and ulna were fused entirely except at the broad proximal and narrow distal interosseous spaces. The ulna was longer than the radius, and its reduced body and distal end were fused at the caudomedial surface of the radius. 5. The carpal bones were six in number. There were radial, intermediate, ulnar, accessory, second-third and fourth carpal hones in carpal bones. 6. The metacarpal bone was composed of a large metacarpal bone resulted from the fusion of the third and fourth metacarpal bones, and there was a metacarpal tubercle at the dorsolateral part of the proximal end. There were no vestiges of the second and fifth metacarpal bones. 7. The digits were composed of third and fourth digits and each digit was composed of the proximal, middle and distal phalanges. 8. The sesamoid bones were six in number. There were two at the fetlock joint and one at the coffine joint palmarly in each digit. 9. The ratios of the lengths among the scapula, humerus, antebrachium and metacarpal bone were 1.42 : 1.47 : 1.77 : 1.00 in the left and 1.42 : 1.45 : 1.77 : 1.00 in the right, respectively.

Purpose: The purpose of this study was to investigate the effects of home exercise program and exercise program of round shoulder adjustments on the level of trapezius muscle activity and attention capacity for middle school students. Method: The participants in this study were composed of 21 middle school students. We made the students lie on the floor in prone position, then measured the height of their acromion from the floor. We chose participants for our study whose measurement values were over 2.5cm. We divided them into two groups, one is for the experimental group, and the other is for the control group. The experimental group exercised three days a week for 6 weeks, including home training, and the control group didn't exercise. We used EMG to measure the trapezius muscle's activity and used a Stroop test for the measurement of the students' attention capacity. Results: The results of our study are as follows. There was no significant difference between the experimental group and the control group. However, there was a significant difference within the experimental group when comparing pre and post training results for Trapezius muscle activity and attention capacity. Conclusion: We found that correcting round shoulder symptom increases the Trapezius muscle activity and students' attention capacity. Future experiments should investigate with systemical management. Also, we need to increase the frequency of the exercise and participants.

As a means to get a better understanding of the kind of form changes to which is subject the neck of the men, in its aging process, several measurement recordings on a vertical and horizontal sections were carried. Subjects were young, middle aged and elder men (15 in their twenties, 11 in their forties and again 11 in their sixties) 1) The analysis of the meansurement results led us to distinguish 3 types of subjects according to the position of the their Adam's apple with regard to the horizontal plane containing their 7th cervical vertebrae point : clearly above (Type I), next to(Type II), clearly below(Type III). We found that young men correspond to the Type I and II, middle aged men to the Type ll and 111 and elder men only to the Type III. 2) The comparison of the horizontal sectional surface contained in the planes corresponding to the 4 points, shows a larger sectional surface for elder men in the Adam's apple plane, accompanied by a change of position of the Adam's apple forwards. As for the front neck point plane, the body sectiolial surface is larger in depth in elder men, without much change in breadth. And for the acromion point plane, we observed also an increase in depth, but with a decrease in breadth corresponding partially to the atrophy of the thoraric cage in eldermen.

Background: Rounded shoulder posture (RSP), a postural abnormality, might cause shoulder pain and pathologic conditions. Although most previous research has investigated RSP focusing on the proximal structures of the shoulder, such as the scapula and pectoralis muscles, the relationship between RSP and anterior distal structures of the upper extremity, such as the biceps brachii muscle and elbow joint, is not clearly understood. Objects: This study aimed to investigate the correlations between RSP and the biceps brachii length, elbow joint angle (EJA), pectoralis minor length, general pectoralis major length, humeral head anterior translation (HHAT), glenohumeral internal rotation (IR), external rotation (ER), and horizontal adduction (HAD). Methods: Twelve subjects with RSP (6 male, 6 female) were recruited. All subjects fulfilled the RSP criteria indicated by a distance ${\geq}2.5cm$ from the posterior aspect of the acromion to the table in the supine position. The examiner measured each of the following parameters twice: RSP, biceps brachii length, EJA, pectoralis minor length, pectoralis major length, HHAT, glenohumeral IR, ER, and HAD. Pearson's correlation coefficient(r) was used to assess the correlation between RSP and all the variables. Results: There was a significant moderate positive correlation between RSP and biceps brachii length (r=.55, p=.032), moderate negative correlation between RSP and pectoralis minor length (r=-.62, p=.015), and moderate positive correlation between RSP and HHAT (r=.53, p=.038). Conclusion: The biceps brachii length, pectoralis minor length, and HHAT could be used to evaluate patients with RSP. Better understanding of the correlation between these factors and RSP could help in the development of effective methods to treat patients with this condition in clinical management.

Background: This study was carried out to determine whether non-face-to-face physical therapy would have similar exercise effects to face-to-face physical therapy. Hence, we developed an approach for patients, unable to visit hospitals due to circumstances such as the COVID-19 pandemic, to conduct physical therapy comfortably at home. Objects: This study aimed to compare the effects of a face-to-face and a non-face-to-face physical therapy treatment on improving a rounded shoulder posture. Methods: The participants with rounded shoulders were randomly divided into a face-toface group (n = 15) and a non-face-to-face group (n = 15), and each group performed exercises for four weeks. The exercise program consisted of the bare hands exercise, Thera-Band exercise, and foam roller exercise. The participants in the face-to-face group came to a designated place to perform their exercises, and those in the non-face-to-face group performed the exercises at their own home using Google Meet (Google). Acromial height, total scapular distance (TSD), shoulder pain and dysfunction index (SPADI), and pectoralis minor thickness were measured. Data analysis was performed using the R Statistical Software (R Core Team), and a normality test was performed using the Shapiro-Wilk test. Results: There were no significant differences between the face-to-face and the non-face-toface groups (p > 0.05). When comparing the differences before and after the exercises, both the face-to-face and the non-face-to-face groups showed significant differences in acromial height, SPADI, and pectoralis minor thickness (p < 0.05), and both groups showed no significant difference in TSD before and after the exercises (p > 0.05). Conclusion: The results of this study support the results of previous studies reporting that shoulder stabilization exercise and pectoralis minor stretching training improves round shoulders. In addition, this study revealed that both the face-to-face and the non-face-to-face physical therapy treatments had therapeutic effects.

Purpose: To evaluate the association of subacromial bursa inflammation with acromial shape and shoulder pain in subacromial impingement syndrome. Materials and Methods: 24 cases with subacromial impingement syndrome were reviewed. Eighteen patines were males and six females(mean age: 58.3 yrs). During arthroscopic operation, the specimens were taken from subacromial bursa with arthroscopic knife($1{\times}1$ cm size). The shape of acromion were classified according to Bigliani grading system. The shoulder pain of patients was graded with visual analog scale (VAS). The grade of inflammation was classified to the pathological three grade system (mild, moderate, severe) by pathohistological 8 factors. Results: Of total 24 cases, 9 cases were the pathological grade I and 15 cases were grade II. None was grade III. In the 9 cases of pathological grade I, 6 cases were the radiologic grade II of acromial shape and 3 cases were grade III. In the 15 cases of pathological grade II, 5 cases were the radiologic grade II and 10 cases were grade III. The VAS was 7 point at pathological grade I and 8 point at grade II. As the statistical analysis, the pathological grade of subacromial bursa was associated with acromial shape (p<0.05), but not associated with pain of patient (p>0.05). Conclusion: Our study suggests that pathological grade of subacromial bursa inflammation was associated with acromial shape. But pathological grade of subacromial bursa inflammation was not associated with shoulder pain of patients.

Purpose : The purpose of this study was to find out useful radiological projection of shoulder subluxation in patients with post-stroke hemiplegia. Methods : A total of 33 patients with post-stroke hemiplegia were included(20 men and 13 women, mean age 62.3 years) and having the subluxed shoulder over one finger breath. The shoulder subluxation was determined as the ratio of the radiographic vertical and horizontal distance. The vertical distance was determined by measuring the distance between the most inferolateral point of the acromion and the central point of the humeral head. The horizontal distance was determined by measuring the distance between the central point of the glenoid fossa and the central point of the humeral head. To measure of the shoulder subluxation, the shoulder AP, axial and transthoracic lateral projections were taken on both affected and unaffected shoulders. We analyzed the difference of subluxation distance by t-test. Results : When patients was in sitting position, the average time of being shoulder subluxation was 123 second. There was significant difference between supine($49.90{\pm}13.6\;mm$) and sitting position($60.72{\pm}16.3\;mm$) in the vertical distance of shoulder anterior-posterior projection. Also, there was significant difference on transthoracic lateral projections, Affected $35.92{\pm}6.2\;mm$, Unaffected $28.76{\pm}5.4\;mm$. But in case of shoulder axial projection(supine position), there was no significant difference (Unaffected and affected was $23.01{\pm}9.0\;mm$, $22.45{\pm}8.2\;mm$ each). Conclusion : Radiological projection of shoulder subluxation has diagnostic value when it goes after check out the process of subluxation through finger breadth test. For this, patients must be in sitting and shoulder neutral position about 2 minutes. In addition, Shoulder anterior-posterior and transthoracic projection were significant to diagnose subluxation. But in axial projection, there wasn't meaningful differences.
