Purpose : The purpose of this study was to provide information for developing a rehabilitation intervention that improves adaptation and the quality of life after mastectomy by investigating the level of physical function and fatigue in mastectomy patients. Methods : The subjects were 63 patients selected from St. Mary's Kangnam hospital Data were collected from March to June, 2003. Physical function was measured by the range of motion of the shoulder joint, shoulder function, and physical symptoms. fatigue was measured by using the Brief Fatigue Inventory (BFI). Results : The range of motion on the affected side was significantly lower than that in the healthy side. Shoulder function score was highest in the item of 'pull on pants', and lowest in the item of 'back zipper'. Physical symptom score was highest in the item of 'numbness', and lowest in the item of 'Itching sensation'. The highest item interfered by fatigue was 'normal work (includes both work outside the home and daily chores)'. Conclusion : The result of this study suggests that effective rehabilitation intervention for mastectomy patients should be needed to improve physical function, and reduce fatigue.

The purpose of this study was to quantify the isokinetic peak torque and range of motion at the shoulder in 8 national male volleyball players who played during the 2008 professional leagues. In this study the strength and range of motion data in the internal rotation(IR) and external rotation(ER) of shoulder joint were measured with isokinetic measurement system(Biodex Inc) and motion analysis system (Simi motion system Inc.) from 3 volleyball players with atrophy of the infrasupinatus and 5 volleyball players without atrophy of the infraspinatus. Peak torques were determined using isokinetic measurement on the shoulder joint rotator at the point of angular velocities of $60^{\circ}$/s. Significant difference was found in the peak torque, IR / ER ratio and the range of motion through assessment of the dominant shoulder between two groups. we recommended functional exercises that improve both external rotators strength and stretching exercise for internal rotation in the dominant side during the prevention programs in volleyball players.

The purpose of this study is to investigate the types and effects of rehabilitation by systematically examining the rehabilitation research for improving the shoulder ROM in breast cancer resection patients. For a systematic review, a total of 8 studies were finally selected through three databases including RISS. As a result of this study, the level of qualitative was 4 studies(50.0%) in level III, and the rehabilitation period varied from 4 weeks to 12 weeks. As for the type of rehabilitation, 3 studies(37.5%) were occupational therapy and physical therapy. The ROM of the shoulder joint was 7 studies(87.5%) of flexion, extension, and external rotation. A goniometer was used in 8 studies(100.0%) to evaluate the ROM of the joint as a measuring tool. This study is expected to provide basic data in the field of convergence when developing and applying interventional protocols for patients with limited ROM due to breast cancer resection.

Good health-related quality of life is regarded as the goal of elderly residential care. Treatment for breast cancer produces side effects that diminish functional capacity and quality of life among survivors. Tai-Chi exercise offers the benefits of fitness and health. Tai-chi has been claimed to generate beneficial effects with respect to a wide range of diseases. The object of this research is to evaluate the effects of tai chi exercise on shoulder joint movement and cardiovascular function in elderly breast cancer patients. The subjects were 40 patients residing in B metropolitan city, who had undergone surgery for breast cancer within 2 months. They underwent post-operative radiotherapy and an anti-cancer chemical treatment. They practiced tai-chi exercise for 60 min a day, four times a week for 12 weeks under the direction of a special tai-chi instructor. Shoulder joint movement and heart rate, were measured before and after the experiment. The results were as follows; Shoulder joint movement, including flexion, extention, adduction and abduction, significantly increased (p<0.05) after treatment, and heart rates significantly decreased after treatment (p<0.05). From the results, Tai-Chi exercise was shown to be extremely effective in improving shoulder joint movement and heart rate in elderly breast cancer patients. Further study is needed in this area.

Spinoglenoid cyst have been reported in small series in the orthopaedic literature in association with SLAP lesion, which is one of less common causes of shoulder pain. Authors experienced one case of spinoglenoid cyst with SLAP lesion initially missed with ultrasonographic examination and physical examination. This case was confirmed by MRI, EMG and arthroscopic surgery was done. When clinicians cannot find a definite cause of shoulder pain and decreased power of rotator cuff tendon with ultrasonographic examination, they need further study such as MRI and EMG with careful physical examination. Clinicians need to aware of the limitation of ultrasonography for spinoglenoid cyst especially, (1) cyst size is small, (2) location of cyst is too deep to detect and along the scapula spine from SLAP lesion.

The purpose of this study was to investigate difference of activity of scapular stabilizer muscles among push-up, knee push-up and wall push-up exercise. Eight male college students were recruited as participants without any history of shoulder or pathology. The results showed that serratus anterior, anterior deltoid, infraspinatus were higher muscle activities than other scapular stabilizer muscles during push-up exercise and muscle activity of standard push-up exercise was higher muscle activity than that of Knee and Wall push-up exercise. Also, We know that knee push-down exercise was more effective than wall push-down exercise for scapular stabilization.

Objectives: The purpose of this study was to determine whether the sacrooccipital category II blocking technique may improve abdominal muscle endurance and alleviate shoulder pain caused by pelvic tilting. Methods: A total of 50 subjects diagnosed with category II sacroiliac joint instability and lower back pain were randomly assigned to the control or treatment group. The sacrooccipital technique category II blocking procedure (2-min duration) was performed 3 times a week until the category II indicator of joint instability had subsided. The control subjects were subjected to a sham procedure of equal duration and frequency. We assessed abdominal muscle endurance using the partial curl-up test and shoulder pain using a visual analogue scale, before and immediately after the intervention and 2 weeks after the intervention. Results: On two-way analysis of variance with repeated measures on time factor, significant treatment and interaction effects on muscle endurance were found. A significant interaction effect, but not treatment effect, was found for shoulder pain. Post hoc test showed that the shoulder pain was reduced immediately after intervention (treated group) and 2weeks (control and treated group) after the intervention as compared to before the intervention. Conclusions: This study suggests that sacrooccipital category II blocking can be used to alleviate shoulder pain caused by pelvic instability. The mechanisms behind the long-term benefits may include an increase in abdominal muscle endurance.

A statistical approach was carried out to analyze joint moments acting on the six subjects performing a right-handed seated task. The dynamic task analyzed consisted of moving a hand-held weight of lkg mass back and forth in front of a subject's chest at the shoulder level in an upright seated position. We used experimental data obtained in the Biomechanics Laboratory of the University of Michigan. Based on the acquired data from three trials by each subject, moments were calculated using a 3-dimensional biomechanical model at such articulations as wrist, elbow, shoulder, the third lumbar spine, hip, knee, and ankle joints. The linear correlation and the two way analysis of variance were applied to the calculated joint moments in order to investigate inter-subject and inter-trial varations. The results obtained showed that the largest magnitude and deviation of moment was found at the third lumbar spine, that any linear relationship could not be found between moment and its equivalents attempted in this study, and that the maximum value and deviation of moment acting on each joint were statistically the same for all three trials but those were statistically not the same for all six subjects.
