Background: This study aimed to determine the effects of pectoralis minor stretching, lower trapezius strengthening exercise with serratus anterior strengthening exercise to find an effective therapeutic exercise for alignment, shoulder range of motion, muscle imbalance of rounded shoulder patient. Methods: This study targeted on a total of 28 male subjects, aged 20s and 30s, and randomly divided the subjects into each group, with 14 subjects each. The experimental group performed pectoralis minor stretching, lower trapezius strengthening exercise, and serratus anterior strengthening exercise, while the control group performed pectoralis minor stretching and lower trapezius strengthening exercise. Results: both group showed an increase in active range of motion for shoulder flexion, a muscle activity of the serratus anterior muscle and the lower trapezius muscle, a decrease in muscle activity of the upper trapezius muscle, and a significant improvement in scapular alignment after the intervention. In the comparison between group, the experimental group showed greater increased shoulder joint flexion range of motion, serratus anterior muscle activity, and decreased upper trapezius muscle activity than the control group. Conclusion: Performing serratus anterior strengthening exercises with pectoralis minor stretching and lower trapezius strengthening exercises is effective for improving the active range of motion in shoulder joint flexion and muscle imbalance

The purpose of this study was to measure intra-rater and inter-rater reliability and range of motion for measurement of passive shoulder internal rotation range of motion and to compare anterior glide distance of humeral head in three methods. Fifty healthy subjects and fifty patients with shoulder musculoskeletal pain were recruited for this study. The subjects' passive shoulder internal rotation range of motion was measured by visual estimation, manual stabilization, and pressure biofeedback unit methods. In two trials, measurements were performed on each subject by two examiners. Intraclass correlation coefficient (ICC(3,1)) was used to determine the reliability of each measurement. The intra-rater reliability of the three methods was excellent (ICC=.77~.93) in both groups. The inter-rater reliability of the visual estimation method was poor (ICC=.20, .29), the manual scapular stabilization method was poor and fair (ICC=.09, .50), and the pressure biofeedback unit method was excellent (ICC .86, .75) in the experimental and control groups. In the experimental group, the difference of examined range of motion by each examiner was significant in the visual estimation method and manual scapular stabilization method, but there was an insignificant difference between the groups is the pressure biofeedback unit method. This result suggests that the intra-rater and inter-rater reliability of a pressure biofeedback unit was better than the other methods. The difference in distance of the anterior glide of humeral head was insignificant among all the methods. The pressure biofeedback unit method was the most reliable method, so it is proposed to be a new and reliable method to measure internal rotation range of motion.

Purpose: This study was aimed to determine the effects of thoracic spine thrust manipulation on muscle activities of the scapular upward rotators and middle deltoid, active range of motion (AROM), shoulder pain, and rounded shoulder posture in young adults with rounded shoulder. Methods: The subjects were 30 young adults (14 males, 16 females) with rounded shoulder. Thirty subjects were randomly assigned to an experimental (manipulation) and control (placebo) groups of fifteen subjects respectively. The manipulation group received the manipulation (high velocity, low amplitude), which was performed by a physical therapist with the subject in the supine position and with the arms crossed over the chest and hands passed over the shoulders. For the sham group, the same procedure was performed, with the exception that the high-velocity thrust was not applied. Measurements were taken before and after the intervention. Muscle activity of upper and lower trapezius, serratus anterior, middle deltoid was measured using surface electromyography. Visual analog scale (VAS) was used for shoulder pain. Goniometry was used for shoulder abduction active range of motion (AROM). Straight edge was used for supine rounded shoulder posture (RSP) distance. Results: The muscle activity of the upper trapezius, lower trapezius and middle deltoid muscle increased significantly after the intervention (p<.05). However, no significant difference was observed in serratus anterior muscle (p>.05). The VAS was significantly decreased and AROM significantly increased after the intervention (p<.05). The distance of RSP were not significant (p>.05). The control group showed no differences before and after the intervention (p>.05). Conclusion: The results of this study suggest that thoracic spine thrust manipulation can be an effective component of treatment plan to improve pain and function.

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).

Background: Patients who have rotator cuff arthropathy experience a limited range of motion (ROM) of the shoulder joint and experience problems in performing their daily activities; however, no evidence is available to suggest the exact ROM of the shoulder joint in this population. Therefore, this study sought to determine the degree of motion of the shoulder joint in three planes during different activities. Methods: Five subjects with rotator cuff injuries participated in this study. The motion of the shoulder joints on both the involved and normal sides was assessed by a motion analysis system while performing forward abduction (task 1), flexion (task 2), and forward flexion (task 3). The OpenSIM software program was used to determine the ROM of the shoulder joints on both sides. The difference between the ranges of motion was determined using a two-sample t-test. Results: The ROMs of the shoulder joint in task 1 were 93.5°±16.5°, 72.1°±2.6°, and 103.9°±25.7° for flexion, abduction, and rotation, respectively, on the normal side and 28°±19.8°, 31°±31.56°, and 48°±33.5° on the involved side (p<0.05). There was no significant difference between the flexion/extension and rotation movements of the shoulder joint when performing task 1. However, the difference between flexion and rotation movements of the shoulder joints for the second task was significant (p>0.05). Conclusions: Those with rotator cuff arthropathy have functional limitations due to muscle weakness and paralysis, especially during the vertical reaching task. However, although these individuals have decreased ROM for transverse reaching tasks, the reduction was not significant.

The purpose of this research is to measure range of virtual hip joint and lower limb joints motion such as the hip, knee and ankle joints for 47 young male students. The results of ANOVA revealed that anthropometric dimensions including weight and stature did not show any significant effects on the range of virtual hip joint and lower limb joints motion and the range of motion with two degrees of freedom at the shoulder, virtual hip and hip joints. Anthropometric dimensions such as age, weight, statuire, arm length, shoulder height and leg length were found to be lowly correlated with the range of virtual hip joint and lower limb joints motion. It is expected that the data on the range of joint motion suggested in this study can be used as a valuable input data when designing workplace, predicting human posture and reach volume, etc.

Shoulder hand syndrome is characterized by pain, vasomotor instability, and tenderness, mainly in the distal upper extremity. The pathophysiologic mechanism of this syndrome is not yet proved. The purpose of this study is to evaluate the usefulness of thermographic imaging on shoulder hand syndrome after stroke for early diagnosis and its clinical pattern analysis including acupuncture and electroacupuncture therapy. This study was performed from June to September in 1996 on 46 stroke patients who were admitted at Oriental hospital of Kyung Hee Medical Center. The study group were 23 patients with shoulder hand syndrome. The control group were 23 patients without shoulder hand syndrome. Skin temperatures on the both upper extremities were measured by Digital Infrared Thermographic Imaging(D.I.T.I.) before the study and 3 weeks later again. The results were as follows; 1. The shoulder hand syndrome group were significantly more restricted in shoulder passive range of motion than the control group. 2. The shoulder hand syndrome group showed significant temperature difference of both dorsal hands. 3. The electroacupunture therapy group were significantly more improved on the temperature difference of both dorsal hands than acupuncture therapy group in 3 weeks later. 4. Both posterior arms showed the biggest temperature difference from 11 to 30 days in shoulder hand syndrome group. 5. The lesser passive ROM(range of motion) of shoulder group showed significantly increased temperature difference of both hands. The above results show that measurement of shoulder passive range of motion and D.I.T.I. is a useful method for early diagnosis on shoulder hand syndrome and its clinical pattern analysis including evaluation of acupuncture and electroacupuncture therapy. Continuous study will be needed for more clinical application and evaluation on shoulder hand syndrome.

PURPOSE: This study examined the effects of Kinesiology taping followed by pectoralis minor muscle self-stretching on the rounded shoulder posture, neck range of motion, and upper trapezius muscle tone in subjects with a rounded shoulder posture. METHODS: Thirty adults with a rounded shoulder posture were assigned randomly to one of two groups, either one that only performed pectoralis minor muscle self-stretching or a group that performed pectoralis minor muscle self-stretching after applying Kinesiology taping ; the subjects underwent four weeks of intervention. Three rounds of intervention were carried out over four weeks, and before and after the experiment, rounded shoulder posture, neck range of motion, and upper trapezius muscle tone creep were measured. RESULTS: Following the interventions, both the experimental and control groups showed significant improvement in the rounded shoulder posture, neck range of motion, upper trapezius muscle tone, stiffness, relaxation, and creep. Significant differences in the post training gains in the rounded shoulder posture and neck range of motion were observed between the experimental and control groups. CONCLUSION: These results showed that a combination of Kinesiology taping and pectoralis minor muscle self-s tretching led to more significant improvement than that seen when only utilizing the application of pectoralis minor muscle self-stretching to change the posture of the subjects with a rounded shoulder posture.

Objectives : The purpose of this study was 1) to investigate the possibility of taking blood stasis pattern as a clinical parameter of frozen shoulder, using blood stasis pattern questionnaire (BSPQ) to frozen shoulder group comparing with normal group, and 2) to find out the relationship of the severity of main frozen shoulder symptoms (pain and limited range of motion of shoulder) and the level of blood stasis pattern through BSPQ analysis. Methods : During the period of January 2010 to July 2010, fifty five frozen shoulder patients who visited outpatient clinic of department of acupuncture and moxibustion in East-West Neo Medical Center, Kyung Hee University and fifty five normal people without shoulder pain nor limited ROM in shoulder joint were evaluated through BSPQ, and to the frozen shoulder group, also evaluated three different visual analogue scales (VAS) of pain (pain on average, pain at night, and pain on motion) and active / passive range of motion (ROM) of shoulder joint. Results : Mean blood stasis pattern score of frozen shoulder patients group was significantly higher than the score of normal group (patients vs normal group : $4.85{\pm}1.68$ vs $3.49{\pm}1.54$). Three different types of pain VAS (on average, at night and on motion) showed low to very low positive correlation with BSPQ scores when analyzed with Pearson's correlation coefficient. ROM levels in shoulder joint were not significantly related to BSPQ scores, though active external rotation range showed low positive correlation with BSPQ scores. Conclusions : Patients with frozen shoulder showed higher blood stasis pattern score in BSPQ but the level of blood stasis pattern is not significantly related to the severity of pain or limitation of ROM in shoulder joint.

In this study describes the design of Exo-suit to assist those who work in unstructured positions. The present study aimed to analyze various types of work, especially those performed in unstructured postures by heavy industry workers. Based on the motion capture analysis results, an attempt was made to develop a shoulder muscle-assistive Exo-suit capable of assisting a wearer who is working using shoulder muscles. In the present study, as the first step of developing a shoulder muscle-assistive Exo-suit, different working scenarios were simulated, and the corresponding motion data were estimated using motion capture devices. The obtained motion data were reflected in the design of the Exo-suit. The main structure of the shoulder muscle-assistive Exo-suit was made of a carbon fiber-reinforced composite to obtain the weight reduction. The shoulder muscle assistive Exo-suit was designed to fully cover the range of motion for workers working in unstructured postures.
