Objectives: The purpose of this study was to determine the effectiveness of hand acupressure in relieving shoulder pain among male manufacturing workers. Methods: A nonequivalent control group was employed using a nonsynchronized design. Data were collected from two manufacturing plants located in metropolitan area U. The data were analyzed with a ${\chi}^2$-test and an independent t-test to perform a homogeneity test, and with repeated ANOVA measures to perform an hypothesis test using the SPSS 21.0 program. Results: Hypothesis 1 that "the experimental group provided with hand moxibustion would score lower for low shoulder pain than the control group" was supported (F=306.05, p<.001). Hypothesis 2, that "the experimental group provided with hand moxibustion would have a wider range of motion than the control group" was also supported with increased flexion(F=7.73, p<.001), extension(F=7.89, p=.001), abduction(F=21.23, p<.001), and horizontal abduction(F=20.89, p=.028). Hypothesis 3, that "the experimental group provided with hand moxibustion would score lower for quality of sleep than the control group" was not supported (F=56.10, p=.091). Conclusions: Hand moxibustion is effective in relieving shoulder pain for male manufacturing workers, in relieving low shoulder pain and increasing the range of motion.

Background: Shoulder stabilization commonly involves two components: the glenohumeral stabilization exercise (GSE) and scapular stabilization exercise (SSE). Despite the fact that the shoulder stabilization has advantageous merit, to our knowledge, only a few studies have compared the superior of the GSE and the SSE. Objects: The purpose of this study was to assess the effects of GSE in patients with nonspecific shoulder pain. Methods: Thirty subjects with nonspecific shoulder pain were randomly divided into an experimental group and control group, each with 15 patients. The experimental group used an GSE, whereas the control group did SSE. All subjects were measured in shoulder stability, scapular symmetric alignment, pain, muscle power, and range of motion before and after the intervention. Results: GSE resulted in significantly better shoulder stability (p=.046, from $8.67{\pm}7.54$ score to $13.93{\pm}9.40$) in the experimental group compared with SSE in the control group. However, no significant effects were observed for scapular symmetric alignment including the angles of inferior scapular distance (p=.829) and inferior scapular height difference (p=.735), pain (p=.113), muscle power including shoulder flexion (p=.723) and abduction (p=.897) and range of motion including shoulder flexion (p=.853) and abduction (p=.472). Conclusion: These findings suggest that GSE may be more effective in increasing the shoulder stability than the SSE in patients with nonspecific shoulder pain, probably through a centralization effect on the shoulder mechanism.

The purpose of this study was to quantitatively investigate the effects of external load upper extremity posture on perceived discomfort. An experiment was conducted for measuring discomfort scores depending upon external loads and upper extremity postures, in which the free modules and numeric estimate method of the magnitude estimation was adopted as a tool for obtaining discomfort ratings. The upper extremity postures were controlled by wrist flexion/extension, elbow foexion, shoulder flexion, and shoulder adduction/abduction. The results showed that all experimental variables except shoulder adduction/abduction were significant at ${\alpha}$=0.01 or 0.05. The effect of external load was very much larger than that of upper extremity postures. Therefore, it is recommended that a new posture classification scheme taking effect of external load to into consideration be developed for quantifying postural load.

The purpose of this study were to determine the intra-rater and inter-rater reliability of shoulder passive range of motion measurement using the "Clinometer + bubble level", a smartphone application and to compare with the intra-rater and inter-rater reliability of measurement using a goniometer. Twenty six patients with stroke were recruited for this study. Two raters measured the passive range of motion of four types of shoulder movements (forward flexion; FF, abduction; ABD, external rotation at $90^{\circ}$ abduction; ER90 and internal rotation at $90^{\circ}$ abduction; IR90) using a goniometer and a smartphone to determine within-day inter-rater reliability. A retest session was performed thirty minutes later to determine within-day intra-rater reliability. The reliability was assessed using intraclass correlation coefficients (ICC) and the standard error of measurement (SEM). The ICC (2,1) for the inter-rater reliabilities of the goniometer and smartphone were good in FF and ABD [ICC (2,1)=.75~.87] and excellent in ER90 [ICC (2,1)=.90~.95]. The intra-rater reliabilities for the goniometer and smartphone were good or more than good, with an ICC (3,1) value >.75, the exception was IR90 measured by rater 2 on the smartphone. These results suggest that smartphone could be used as an alternative method tool for measurement of passive shoulder range of motion in patients with stroke.

Purpose : The purpose of this study is to find out which shoulder abduction angle among the three representative angles of lower trapezius strengthening exercises most effectively improves rounded shoulder posture. Methods : Thirty-one people with rounded shoulders, the subjects of this study, were selected. With the use of a random number table, group A was randomly assigned to a Y-type exercise, group B to a T-type exercise, and group C to an MPC exercise. In the prone position, both arms are abducted at the angles suggested for each group (145 °, 90 °, and 45 °, respectively), and the hands are holding dumbbells to assume a functional posture. With the start signal, the thumb raised the arm to the sky and the arm is raised to the level of the ear for 10 seconds and then returned to the original position. Each week, the strength required was increased by changing the resistance weight, number of times, and set, and the exercise was performed three times a week for a total of four weeks. Results : There was a significant difference in the change in shoulder height of each group after four weeks of exercise in comparison to the amount of change in height before and after exercise in all groups (p<.05). However, no significant difference was observed between all groups in the change in muscle activity of the lower trapezius muscle in each group following four weeks of exercise (p>.05). Conclusion : The results of this study showed that the three lower trapezius strengthening exercises have a positive effect on the improvement of rounded shoulders. In consideration of these results, it is therefore proposed that the various lower trapezius strengthening exercises be applied in parallel during physical therapy for patients with rounded shoulders in clinical practice.

The purpose of this study is to evaluate pain and range of motion in the frozen shoulder and to compare Hold-Relax technique with ROM exercise. Twenty-eight frozen shoulder patients between 41 nod 76 years of age were selected and were divided equally by random distribution into a Hold-Relax technique group and a ROM exercise group. To analyze the therapeutic effect between the two groups, two measurements were taken. A measurement of pain was taken by visual analogue scale and a measurement of range of motion was taken by measuring flexion and abduction degrees with a goniometer. The results were as followings : 1. The Hold-Relax group is more effective in decreasing the pain than the ROM exercise group. 2. The Hold-Relax group is more effective in increasing the range of flexion at the shoulder than the ROM exercise group. 3. The Hold-Relax group is more effective in increasing the range of abduction at the shoulder than the ROM exercise group.

Background: Shoulder function is achieved by the coordinated movements of the scapula, humerus, and thoracic spine, and shoulder disorders can be associated with altered scapular kinematics. The trunk plays an important role as the kinematic chain during arm elevation. Objects: The purpose of this study was to determine the effects of thoracic hyperkyphosis on scapular orientation and trunk motion. Methods: Thirty-one subjects (15 in the ideal thorax group and 16 in the thoracic hyperkyphosis group) performed right-arm abduction and adduction movements in an unconstrained plane. The scapular orientation and trunk motion were recorded using a motion analysis system. Results: Those subjects with thoracic hyperkyphosis displayed greater scapular posterior tilting at a $120^{\circ}$ shoulder elevation, greater scapular internal rotation throughout the arm raising phase, and greater trunk axial rotation at the upper ranges of the shoulder elevation, compared to those subjects with an ideal thorax (p<.05). Conclusion: Thoracic hyperkyphosis can cause scapular instability, greater trunk rotation and greater scapular posterior tilting, and may contribute to preventing the achievement of a full range of humeral abductions in an unconstrained plane.

This study is to report the effectivenes of Meridian-Test (M-test) in 2 cases on shoulder diseases. The M-test was applied to one patient diagnosed with as impingement syndrome and one patient diagnosed with tear of supraspinatus tendon. The changes in numeral rating scale and range of motion were identified to assess the progress of the treatment. After three times treatments, In example 1, the pain decreased from 6 to 0.5 and the range of flexion and abduction increased from $150^{\circ}$ to $180^{\circ}$. In example 2, the pain decreased from 6.5 to 1, and the range of shoulder flexion increased from $120^{\circ}$ to $170^{\circ}$, while the range of abduction increased from $90^{\circ}$ to $170^{\circ}$. Based on the above results, it would be effective to apply M-test to treat shoulder diseases in these two cases.

Background: Subjects with frozen shoulder (FS) might not be comfortable with vigorous physical therapy. Clinical trials assessing the effect of graded motor imagery (GMI) in FS are lacking. The aim of this study was to determine the effect of GMI as an adjunct to conventional physiotherapy in individuals with painful FS. Methods: Twenty subjects aged 40-65 years having stage I and II of FS were randomly divided into two study groups. The conventional physiotherapy group (n = 10) received electrotherapy and exercises while the GMI group (n = 10) received GMI along with the conventional physiotherapy thrice a week for 3 weeks. Pre- (Session 1) and post- (Session 9) intervention analysis for flexion, abduction, and external rotation range of motion (ROM) using a universal goniometer, fear of movement using the fear avoidance belief questionnaire (FABQ), pain with the visual analogue scale, and functional disability using the shoulder pain and disability index (SPADI) was done by a blinded assessor. Results: Statistically significant difference was seen within both the groups for all the outcomes. In terms of increasing abduction ROM as well as reducing fear of movement, pain, and functional disability, the GMI group was significantly better than control group. However, both groups were equally effective for improving flexion and external rotation ROM. Conclusions: Addition of GMI to the conventional physiotherapy proved to be superior to conventional physiotherapy alone in terms of reducing pain, kinesiophobia, and improving shoulder function for stage I and II of FS.

The purpose of this study was to find the effects of scapular pattern and hold-relax technique of propriocetive neuromuscular facilitation(PNF) on the range of motion(ROM) and to find the effects of pain relieve through visual analogue scale(VAS) in frozen shoulder patients. The subjects were consisted of thirty frozen shoulder patients(men ; 9, women ; 21). The measurement of the shoulder range of motion was taken by measuring the degrees of flexion, abduction, and external rotation with a goniometer and the measurement of pain was performed by VAS from pre treatment to one to four weeks The results were as follows : 1. There was the statistical significance not only in the range of motion such as shoulder flexion, abduction, and external rotation, but also in VAS during four weeks(p<.05). 2. By the result of Scheffe's multiple comparison test. there was statistical significance between the values of pre treatment and treatment after one week in the range of motion of shoulder flexion. In that of shoulder external rotation, there was statistical significance between the values of pre treatment and treatment after one week, and between those of treatment after one and two weeks. As the result of this statistical significance of shoulder external rotation, the early treatment was thought to be more effective. However, there was statistical significance in the treatment after two and three weeks in shoulder abduction and was statistical significance between the values of pre treatment and the treatment after one weeks, and between those of treatment after two and three weeks in VAS (p<.05). 3. There was not statistical significance between men and women in the range of motion of the shoulder and in VAS(p>.05). 4. There not statistical significance between th right and left frozen shoulder patients in the range of motion of shoulder and in VAS(p>.05).
