Background: Stretch-oriented home exercise programs are often used as treatments for patients with adhesive capsulitis; however, there is lack of research on home exercise programs to strengthen rotator cuffs. Objects: The aim of this study is to investigate the effect of home exercise programs for rotator cuff strengthening on pain, range of motion (ROM), disability level, and quality of life in patients with adhesive capsulitis. Methods: Twenty-two patients with adhesive capsulitis volunteered to participate in this study. The subjects were randomly divided into an experimental group (n = 11) and control group (n = 11). For the experimental group, manual therapy and home exercise programs for rotator cuff strengthening were applied for 6 weeks; for the control group, only manual therapy was applied for 6 weeks. Shoulder pain (quadruple visual analogue scale, QVAS), ROM, disability (shoulder pain and disability index-Korean version, SPADI), and quality of life (world health organization quality of life scale-Korean version, WHOQOL-BREF) were evaluated at baseline, after 3 weeks, and after 6 weeks of intervention. The changes in the measurement variables were analyzed by using repeated measure analysis of variance. Results: Significant differences were observed between the experimental group and control group in the QVAS; SPADI-pain scores; SPADI-disability scores; SPADI-total scores; flexion, abduction, internal and external rotation ROM of the glenohumeral joint; and WHOQOL-BREF total, overall, physical health, and psychological scores. All groups displayed statistically significant improvements as observed in the QVAS, SPADI, flexion, abduction, external and internal rotation ROM of the glenohumeral joint, and WHOQOL-BREF. Conclusion: Home exercise programs for rotator cuff strengthening had a positive impact on shoulder pain, shoulder ROM, disability level, and quality of life in patients with adhesive capsulitis. Therefore, we propose the use of home exercise programs for rotator cuff strengthening in the exercise rehabilitation of patients with adhesive capsulitis.

The purpose of this study was to analyze the direct measurement data of 40-59 year old middle-aged men from Size Korea's 7th anthropometric survey, and to identify the body shape characteristics and to type the body shape of middle-aged men. Through this, this study aimed to provide basic data necessary for the clothing patterns of middle-aged men with excellent fit. The data was SPSS Ver. 24.0 program analysis. Factors extracted six including body horizontal, vertical, shoulder, waist front length, leg thickness, and shoulder deflections. The body shape of middle-aged men was classified into three types. Type 1 had a thin body circumference, a narrow width, a low height, a short waist front length, and a thin ankle and calf. Type 2 had a high body height, a long waist front length, a normal circumference and width, a thick ankle, a calf, and a sagging shoulder. Type 3 had a large body circumference, a wide body, a wide shoulder, and a long waist front length. A prominent feature of the changes in body shape of middle-aged men is the increase in the circumference and thickness items due to abdominal protrusion and fat accumulation. Therefore, pattern design according to these physical characteristics is considered to be necessary.

Background: Most acromioclavicular joint (ACJ) injuries are caused by direct trauma to the shoulders, and various methods and techniques are used to treat them; however, none of the options can be considered the gold standard. This study examines the horizontal stability of the ACJ after a complete dislocation was repaired using one of two Ethibond suture techniques, the loop technique and the two holes in the clavicle technique. Methods: In this single-blind, randomized clinical trial, 104 patients diagnosed with complete ACJ dislocation type V were treated using Ethibond sutures with either the loop technique or the two holes in the clavicle technique. Horizontal changes in the ACJ were radiographically assessed in the lateral axial view, and shoulder function was evaluated by the Constant (CS) and Taft (TS) scores at intervals of 3, 6, and 12 months after surgery. Results: The horizontal stability of the ACJ was better with the two-hole technique than the loop technique at all measurement times. CS and TS changes showed a significant upward trend over time with both techniques. The mean CS and TS at the final visit were 95.2 and 11.6 with the loop technique and 94.0 and 11.9 with the two-hole technique, respectively. The incidence of superficial infections caused by the subcutaneous pins was the same in the two groups. Conclusions: Due to the improved ACJ stability with the two-hole technique, it appears to be a more suitable option than the loop technique for AC joint reduction.

Background: Widespread pain partially depends upon sensitization of central pain mechanisms. However, mechanisms controlling pain distribution are not completely known. The present study sought to assess skin temperature variations in the area of experimentally-induced pain and potential sex differences. Methods: Pressure-pain thresholds (PPTs) were measured on the right infraspinatus muscle. At the end of Day 0, all participants performed an eccentric exercise of the shoulder external rotators to induce muscle soreness 24 hours after. On Day 1, participants indicated on a body chart the area of pain induced by 60 seconds of suprathreshold pressure stimulation (STPS; PPT + 20%) on the right infraspinatus muscle. Skin temperature variations in the area of referred pain were recorded with an infrared thermography camera, immediately before and after the STPS. Results: Twenty healthy, pain-free individuals (10 females) participated. On Day 0, the pre-STPS temperature was higher than the post-STPS temperature on the arm (P = 0.001) and forearm (P = 0.003). On Day 1, the pre-STPS temperature was higher than the post-STPS temperature on the shoulder (P = 0.015), arm (P = 0.001), and forearm (P = 0.010). On Day 0, the temperature decrease after STPS in females was greater than in males on the forearm (P = 0.039). On Day 1, a greater temperature decrease was found amongst females compared with males at the shoulder (P = 0.018), arm (P = 0.046), and forearm (P = 0.005). Conclusions: These findings indicate that sympathetic vasomotor responses contribute to expand pressure-induced referred pain, especially among females.

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.

Purpose: This study analyzed the features of humeral head decentralization in large to massive rotator cuff tears with a shoulder dislocation in the elderly. Moreover, shoulder instability and treatment were reviewed. Materials and Methods: From May 2005 to February 2017, Group A containing 45 cases (45 patients) over 65 years old accompanied by a large or massive rotator cuff tear with a shoulder dislocation and Group B containing 45 cases (45 patients) without a shoulder dislocation were enrolled. The mean ages in Groups A and B were 73.2 and 72.1 years old, and the mean follow-up periods were 30.7 and 31.3 months, respectively. Twenty-one cases (46.7%) in Group A underwent rotator cuff repair, and 8 cases (17.8%) underwent concomitant rotator cuff repair with Bankart repair. Sixteen cases (35.6%) underwent reverse total shoulder arthroplasty for cuff tear arthropathy. 45 cases (100%) in Group B underwent rotator cuff repair. The off-the center and head elevation were measured in the preoperative magnetic resonance imaging (MRI) of Groups A and B. The preoperative and postoperative visual analogue scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score, and University of California Los Angeles (UCLA) score in Groups A and B were compared. Results: In Groups A and B, the mean off-the centers were posterior 7.41 mm and posterior 2.02 mm (p=0.03), and the mean head elevations were superior 6.66 mm and superior 2.44 mm (p=0.02), respectively. The mean ASES scores of Groups A and B were 32.8 and 33.4 before surgery, and 77.1 (p=0.02) and 78.1 (p=0.02) after surgery (p=0.18), respectively. The mean UCLA scores of Groups A and B were 13.1 and 12.8 before surgery, and 28.9 (p=0.02) and 29.5 (p=0.01) after surgery (p=0.15), respectively. Conclusion: Patients over 65 years old with a shoulder dislocation in large to massive rotator cuff tears had higher off-the center and head elevation on the preoperative MRI than those without a shoulder dislocation. This measurement can help predict preceding shoulder instability. Early rotator cuff repairs should be performed and other treatments, such as Bankart repair and reverse total shoulder arthroplasty, should also be considered.

The body changes of the elderly women are the forward tilt of the neck and shoulder point shrinkage of the spinal column, and protrusive abdomen. Unfortunately, few data based on body measurements for elderly women existed and a few studies are limited to the body figure of the elderly women. If these changes are not applied to the manufacturing of the clothing, almost of the elderly women will be unfitted with their clothing. So to improve the fitting of the elderly women, it is necessary to use the standard size systems for elderly women. This report is the first study to develop the standard tables of body measurements to be used for improving the fit of garments and patterns for women aged 60 and older. This study drew from anthropometric measurements of 337 and photographic measurements of 276 women aged 60 and older. It described the protocol of anthropometric measurement, the comparison between the measured data and the data on which National anthropometric survey of Korea 1997 is based, and the development of body measurement standard tables for elderly women. And we also considered the regional difference of body dimensions in order to develop the national size standards for elderly women. Further study would include the classification of body dimensions and description of each figure type for sizing apparel of women aged 60 and older.

The purpose of this study was to characterize the upper body shape of men in their 50s and 60s by analyzing direct measurement data. Sixty one direct measurement items were analyzed. Subjects (n = 752) were classified based on 5 factors into 4 body types. In order to acquire accurate upper body shape information by analyzing body type using the 8th Size Korea direct measurement data, body shapes were classified through factor and cluster analysis. As a result of the comparative analysis of the upper body measurements from the 5th to the 8th Size Korea measurement, it was found that waist circumference item tended to increase significantly from the 5th Size Korea measurements. The upper body type of middle aged males were classified using five factors: the trunk obesity factor, the trunk vertical factor, the width of the back shoulder, the vertical factor behind the back, and the length factor of the upper body. Middle-aged men were classified into four body types through cluster analysis. Type 1 is relatively short with big arms, Type 2 has wide shoulders and thin arms, and in Type 3, the upper body is relatively long. Type 4 is the most obese upper body.

This research is the initial step for establishing a convertible body sizing table applicable to the Korean and American female apparel industry. All 3D female measurement data of the two countries were obtained from Size Korea Project and SizeUSA Project. The sample subjects used in this study were 1,988 Korean and 6,306 American females. Thirty-four(34) variables were chosen as the principal measurements in making garments. The conclusion of this research was as follow: First, it was determined that American women were larger and longer than Korean women in all measurement except shoulder slope measurement. Second, according to the differences analysis of the each age group in Korean Females, all measurements except hip girth had significant differences among the age groups. In case of American females, all measurements except arm length(shoulder to wrist) had significant differences among the age groups. Third, in the comparison of differences between the age groups of the two countries' women, some dimensions varied significantly with age, while others did not show any statistical significance among the age groups. Fourth, according to the t-tests of same age groups between Korean & American female measurements, American female measurements were larger and longer than Korean in all measurements except crotch length total, shoulder slope, hip girth-bust girth and hip girth-waist girth.
