Objective : The purpose of this study is to observe effects of Occupation-Based bilateral UE training for chronic stroke. Methods : 4 patients with hemiplegic stroke were divided into two groups: experimental group and control group. From May to August 2016, we conducted a occupation - based bilateral UE training and a traditional bilateral UE training for 5 weeks, 3 times a week, and 60 minutes per session for each subject. EMG, accelerometer, ARAT, Y-BAT, SIS, and COPM were performed before and after the intervention. Results : The experimental group showed a large changes before and after intervention in ECR, DA and all items except for hand function and memory of SIS, compared with the control group. Also, the experimental group showed a large change before and after the intervention compared to the control group in the accelerometer measuring the amount used of bilateral hand and grasp, pinch, and gross movement items of ARAT and COPM, Y-BIT. Conclusions : Occupation-based bilateral upper extremity training was effective in the recovery of upper limb function and social participation through neurological changes. Future research will be required development studies to ensure a high content validity of the Occupation-based bilateral upper extremity training protocol.

Objective : Localized vibration has been shown to have a positive effect on recovery of upper-limb motor function in patients with hemiparetic stroke, but there has been little research on kinematic analysis for qualitative changes in movement. This study investigated kinematic changes in elbow motion during reaching after localized vibration in persons with hemiparetic stroke. Methods : This study used a one-group, cross-over trial design. Ten chronic stroke patients randomly received localized vibrations on the affected biceps brachii for 5, 10, or 20 min, at 70 Hz. Kinematic analysis of reaching was measured using a 3-D motion analysis system. Variables included peak angular velocity, time to peak angular velocity, and movement units during elbow motion. Result : Affected side elbow motion during reaching was faster, smoother, and more efficient after 20 min localized vibration. Peak angular velocity increased (p<0.05), and time to peak angular velocity (p<0.05) and the movement unit were significantly decreased (p<0.05) during elbow motion for reaching. Conclusion : Localized vibration can improve kinematic components during reaching motion in persons with hemiparetic stroke.

The treatment of areas demanding esthetic requirements, such as maxillary anterior teeth, should take into account the achievement of a healthy, harmonious to the surrounding tissue, and an attractive smile line. In this case report, smile line, soft tissue and hard tissue morphology, and the anatomy and proportion of the tooth, must be considered. In patients with unesthetic maxillary anterior ratio due to inadequate gingival contour and diastema caused by peg lateralis, it would be challenging to achieve an esthetic restoration by orthodontic treatment alone. In such case, after orthodontic treatment, dento-gingivo-facial compositional diagnosis and analysis, followed by gingivectomy and prosthodontic restoration is needed to improve the interdental mesial/distal, width/length ratio to achieve a satisfactory esthetic result. In addition, when improving the tooth proportion of peg lateralis by prosthodontic treatment, Porcelain laminate veneer (PLV), which results in less tooth structure loss, reproduction of similar shade to that of the proximal tooth and high transparency, is recommended. This case report demonstrates esthetic improvements by prosthodontic restoration through systematic diagnosis and treatment procedure in patients with unesthetic maxillary anterior proportion after orthodontic treatment due to peg lateralis by means of two female patients aged twenty years old.

Objective : This study aimed to investigate the effect of simultaneous application of peripheral nerve sensory stimulation and task-oriented training on the improvement of upper extremity motor function after stroke. Methods : This study included 29 patients with hemiplegia. The 14 subjects were in the peripheral nerve sensory stimulation and task-oriented training group for 4 weeks (30 min/d, 5 d/wk), while the 15 control group subjects underwent only task-oriented training for the same duration. The outcome measures were the percentage of voluntary baseline muscle contractions of the wrist and shoulder and Box and Block Test, grip and pinch strength, and Action Research Arm Test. Results : After 4 weeks, muscle activity of extensor carpi radialis, flexor carpi radialis and grip strength and Action Research Arm Test were significantly higher in the experimental group. Conclusion : Simultaneous application of the peripheral nerve sensory stimulation and task-oriented training was found to be superior to task-oriented training for improving upper extremity motor function of adults with stroke.

The purpose of this study is to investigate the effects of task-oriented activities on hand functions in patients with hand injuries. From December 2011 to October 2012, sixteen patients with hand injuries at C Hospital in Changwon, Gyeongsangnam-do, Korea were randomly divided into two groups. One group was subjected to task-oriented activity and the other to general exercise. Two groups performed each activity once a day, three times a week, for four weeks. The group with the task-oriented activities was provided with the tasks according to subject-preference based on the result of Canadian Occupational Performance Measure (COPM). To verify the effect of intervention, the following hand function measures were used: grip strength, pinch strength, and the range of opposition and abduction, Purdue pegboard test and Disabilities of the Arm, Shoulder and Hand (DASH). Both groups showed significant increase in all of the hand function measures after 4-week activities(p<.05). The task-oriented activity group was significantly different from the control group in powers for tip pinch, lateral pinch and three-jaw chuck pinch, Purdue pegboard test and DASH(p<.05) except in grip strength and the range of opposition and abduction suggesting better improvement in hand functions. This study shows that task-oriented activities improve the hand functions more effectively in patients with hand injuries.

The purpose of this study was to investigate the convergence effect of focal vibration stimulation and bilateral upper limb training on the recovery of upper limb function when applied to stroke patients. For 20 stroke patients, divided into an experimental group that performed convergence intervention with focal vibration stimulation and bilateral upper limb training, and a control group who performed only bilateral upper limb training. It was conducted 20 times for 4 weeks, 30 minutes per session. Vibration stimulation was applied to the affected side of the experimental group for 30 minutes during training. Results were measured for the degree of recovery of the affected upper limb function, amount of use on the affected and unaffected sides, the quality and satisfaction in performance on use of both upper limbs. Comparisons were made within groups using a paired-sample t-test and between groups using covariance analysis. As a result of the study, the experimental group showed a significant difference in dexterity and the amount of use on the affected than the control group. The effect size was more than the small effect size in all evaluation items. Through this study, it is thought that the convergence intervention of focal vibration stimulation and bilateral upper limb trainingcan be used clinically as an effective intervention for the recovery of arm function in stroke patients.

The purpose of this study was to provide useful data for clinical occupational therapy by examining the correlation between the use of affected and unaffected sides measured using an accelerometer and upper limb function in chronic stroke patients. In this study, accelerometer, Fugle-Meyer Assessment(FMA), Motor Activity Log(MAL), and Yonsei-Bilateral Activity Test(Y-BAT) was measured on 40 stroke patients who were hospitalized in Won-ju city Y hospital between May 2, 2019 and July 18, 2020. As a result of the study, there was a significant negative correlation between amount of use on the unaffected side and FMA and MAL's Amount of Use(AOU), Quality of Movement(QOM), the quality and satisfaction of performing both hands through Y-BAT. The amount of use on the affected side showed a significant positive correlation with FMA and MAL's AOU, QOM, satisfaction of performing both hands. This study is meaningful in that it suggested the possibility that the actual amount of use on the affected and unaffected side measured using an accelerometer could be used as an evaluation item for upper limb function in stroke patients.

Purpose: The purpose of this study was to examine the effects of music therapy on state anxiety and pain among patients undergoing burn dressing changes. Method: A convenience sample of 32 adult burn patients who were eligible and provided consent were included in the study which was a quasi-experimental study of a nonequivalent control group pretest-posttest design. Fifteen patients in the control group received the routine burn dressing changes but 17 patients in the experimental group listened to self-selected music through headphones connected to a CD player during burn dressing changes for three days. All subjects of the music group chose the type of music that would relax them. Before and after burn dressing changes, subjects completed the State Anxiety Inventory and self-report of pain scores. Result: There was a significant reduction in state anxiety before and after burn dressing changes in those who received music therapy in contrast to those who did not receive music therapy. The music group reported lower pain scores before and after burn dressing changes than did the non-music group. Conclusion: These findings indicate that music therapy composed of self-selected music is a valuable intervention for the treatment of pain and anxiety in patients undergoing burn dressing changes.
