The purpose of this study was to determine the correlation between upper limb muscle power and bat swing speed in elementary school baseball players. This study subjects were 32 subjects. Upper extremity muscle strength was measured in the Both Shoulder joints extensor flexor abductor adductor, Both elbow joints extensor flexor and bat swing speed. The correlation between upper extremity muscle strength and bat swing speed was analyzed using pearson's correlation analysis. There was a significant correlation between dominant upper extremity muscle strength and bat swing speed in the order of shoulder adductor, shoulder abductor, elbow flexor, and shoulder flexor and in correlation between non-dominant upper extremity muscle strength and bat swing speed in the order of shoulder adductor, elbow flexor, shoulder abductor, shoulder extensor, elbow extensor, and shoulder flexor. From these results, it can be seen that the stronger the upper extremity muscle strength, the bat swing speed is the more positive correlation.

The purpose of this study was to investigate the effect of reducing noise and streaking artefacts by applying the Boost3D algorithm in the case of noise and streaking artifacts generated during computed tomography of the shoulder joint. A phantom study using a thoracic phantom including shoulder joint and clinical evaluation were conducted through shoulder joint images of 35 patients who underwent computed tomography of the shoulder joint from September 2020 to October 2020. The evaluation was divided into groups before and after the application of the Boost3D algorithm, and the noise values, signal to noise ratio, and mean to standard deviation ratio values were analyzed. Both noise values and mean to standard deviation ratio values analyzed in phantom image evaluation and clinical image evaluation were statistically significantly lower in the group after Boost3D was applied (p<0.05). Through this study, it was found that noise and streak artifacts were reduced through the application of Boost3D, and the mean to standard deviation ratio was high, which can be judged as an excellent image. If the Boost3D algorithm is used for computed tomography of the shoulder joint, it is thought that excellent images can be obtained with reduced noise and streaking artifacts that may occur in the shoulder joint area.

This paper analyses the torque characteristics of the shoulder and elbow joints of a humanoid robot arm that is useful for an object lifting and transferring task instead of human beings. For the purpose, some typical human lifting behaviors are considered, and various simulations for lifting and transferring an object have been performed by employing a humanoid robot arm having a simple configuration of shoulder and elbow joints. Through the simulation, it is shown that the torque patterns and ranges of the shoulder and elbow joints required for such a humanoid lifting and transferring task can be found earlier in the design of a humanoid robot arm. As a result, this effort is useful for us to design an effective robot arm.

The purpose of this study was to examine the effects of shoulder rehabilitation exercise convergence program. This study used a nonequivalent control group pretest-posttest design. A sample of 58 patients undergoing shoulder surgery, was included. The experimental group was given shoulder rehabilitation exercise convergence program including audiovisual education, shoulder rehabilitation exercise and exercise monitoring. The data were collected using a structured questionnaire and measured range of motion(ROM) of shoulder joint and were analyzed using descriptive statistics, ${\chi}^2-test$, t-test and ANCOVA. The experimental group reported significantly lower shoulder pain than control group(p<.001). Shoulder joint ROM and exercise self-efficacy were significantly higher in the experimental group than in the control group(p=.038; p<.001). This findings indicate that shoulder rehabilitation exercise convergence program can be an effective intervention for shoulder surgery patients. Continued development of convergence interventions for patients undergoing various conditions in practice, is suggested.

This study was to investigate the effects of joint mobilization with two different electrotherapy methods on shoulder external rotation range of motion and pain in mastectomy patients. Thirty mastectomy patients were divided into STMG (joint mobilization+pain scrambler therapy, n=15) and TENMG (joint mobilization+transcutaneous electrical nerve stimulation, n=15). The measurements were performed shoulder external rotation range of motion (ROM), pain (VAS). In both groups, there was a significant difference in the shoulder external rotation ROM, pain after intervention (p <.05). STMG was more decrease in VAS score than TENMG (p <.05). There was no significant difference in shoulder external rotation ROM between the two groups. In order to decrease the pain of mastectomy patients, it was confirmed that STMG was more effective than TENMG.. It is thought that a control group is added to confirm various differences, and more subjects are needed.

A 12-year-old male poodle weighing 2.0 kg presented for evaluation of right thoracic limb lameness. The owner reported that the dog showed recurrent bilateral shoulder joint luxation after a car accident for a year. Recently, the left shoulder joint appeared well maintained, but right shoulder joint luxation was exacerbated. On physical examination, the dog showed non-weight bearing lameness on the right thoracic limb. Craniocaudal radiographic views revealed medial displacement of the right humerus. Mediolateral radiographic views revealed overlap of the glenoid cavity and humeral head. Muscle atrophy of the right thoracic limb, reduced biceps brachii muscle tendon tone, a tear of the medial glenohumeral ligament, and a rupture of the subscapularis tendon were identified intraoperatively. Transposition of the biceps muscle tendon was performed. However, at 7 days, there was evidence of right shoulder reluxation on radiographs. The second surgery was performed with two $2mm{\times}6mm$ cortical bone anchors and a $4mm{\times}6mm$ cancellous bone anchor placed in the cortical bone of the distal scapula and the cancellous bone of the proximal humerus respectively. Two scapular bone anchors were then connected with a humeral bone anchor using heavy nylon suture to minimize shoulder abduction range of motion. On radiographs right after surgery and 6 weeks after surgery, the affected limb revealed no evidence of medial shoulder luxation. At 6 months, no evidence of lameness was noted on the right thoracic limb.
