NREX, an upper limb exoskeleton robot, was developed at the National Rehabilitation Center to assist in the upper limb movements of subjects with weak muscular strength and control ability of the upper limbs, such as those with hemiplegia. For the free movement of the shoulder of the existing NREX, three passive joints were added, which improved its wearability. For the flexion/extension movement and internal/external rotation movement of the shoulder of the robot, the ball lock pin is used to fix or rotate the passive joint. The force and torque between a human and a robot were measured and analyzed in a reaching movement for four targets using a six-axis force/torque sensor for 20 able-bodied subjects. The addition of two passive joints to allow the user to rotate the shoulder can confirm that the average force of the upper limb must be 31.6% less and the torque must be 48.9% less to perform the movement related to the axis of rotation.
Purpose: Hemiplegia patients who were attacked by a stroke suffer from hemiplegic disabilities as well as motor disabilities. For them, rehabilitation cure is being carried out broadly. However, it is not enough for them to use the upper extremity than the lower extremity. For the use of the upper extremity, we examined the effect of constraint-induced movement therapy developed in this research on patients who experienced a stroke following hemiplegia. Method: For this study we selected 36 stroke patients who were registered at the community health center through accidental sampling, and assigned 21 of them to the experimental group, and 15 to the control group. The experimental group had constraint-induced movement therapy for 5 days and 7 hours a day from 9 to o'clock in the morning 9 to 4 o'clock in the afternoon 4 including warmup exercise and main exercise in the rehabilitation room, whereas the control group were restricted. Result: As a result of constraint-induced movement therapy, affected side elbow joint flexion range, side shoulder joint extension range and side shoulder joint of the flexion range of motions increased obviously in the experimental group compared to those in the control group. Conclusion: The result above clearly shows that constraint-induced movement therapy is an effective intervention for the rehabilitation of hemiplegia patients in increasing affected side elbow joint of the flexion range of motion, the shoulder joint extension, and the increase of flexion range of motion.

Purpose : This study sought to investigate research trends regarding joint mobilization type among patients with shoulder joint diseases. Methods : A scoping review was conducted according to the five steps outlined by Arskey and O'Malley and PRISMA-ScR. We searched six domestic databases (ScienceOn, DBpia, Riss, Kmbase, Kiss, KCI) and three international databases (CINAHL, Pubmed, Cochrane central) between 2013 and June 2023. The keyword terms used were 'joint mobilization', 'Kaltenborn', 'Maitland', 'Mulligan', and 'shoulder joint'. Results : There were a total of 44 studies that investigated the topic, and these were divided into quantitative analysis and topic analysis. In terms of publication year, the number of studies within the last five years has increased more than compared to the previous five years, with most of them being randomized clinical trials. In shoulder joint diseases, it was found that the majority of joint movement studies focused on adhesive joint cystitis and shoulder collision syndrome. The Mulligan concept was the most commonly studied type of joint motion. The dependent variables used included pain, joint function (disability), and muscle function. The visual analog scale was the most commonly used for the pain variable, followed by the numeric rating scale. For joint function and disability variables, range of motion was the most commonly used, followed by shoulder pain and disability index, and disabilities of the arm, shoulder, and hand. For muscle function, variables such as muscle tone, strength, and activity were used. Conclusion : We believe that findings of this scoping review can serve as valuable mapping data for joint mobilization research on shoulder joint diseases. Further studies including systematic reviews and meta-analyses based on these results are recommended.

PURPOSE: This study examined the effects of the meridian muscle release technique on the pain and functional movement of patients with myofascial pain syndrome (MPS) of the shoulder joint. METHODS: The subjects of this study included 45 patients with MPS of the shoulder joint. The subjects were divided randomly into the following groups; the meridian muscle release technique group (n=15), the Graston technique group (n=15), and the control group (n=15). Both the meridian muscle release group and the Graston technique group received conventional therapy for 35 minutes initially and were then treated using the meridian muscle releases technique and Graston technique for 10 minutes, respectively. The control group received only conventional therapy for 35 minutes. All three groups underwent treatments three times a week for four weeks. Each subject was evaluated randomly using the VAS, PPT, SPADI and ROM both before and after treatment. RESULTS: The Graston technique group showed a significantly more substantial increase in functional movement (p<.05) than the meridian muscle release technique and control groups. The meridian muscle release technique group had significantly less pain (p<.05) compared to the Graston technique and control groups. CONCLUSION: These findings suggest that the meridian muscle release technique can be useful for decreasing pain and increasing the functional movement of patients with MPS of the shoulder joint.
Purpose: The objective of this case report is to examine the impact of physical therapy using the proprioceptive neuromuscular facilitation (PNF) concept for a patient with shoulder impingement syndrome. Methods: The patient is a 35-year-old female who has felt pain in the right shoulder for one month. The physical examination evaluated sensory integration, pain, joint integration and mobility, posture, reflex integration, range of motion, muscular strength, analysis of movement, and shoulder function. Comprehensive physical therapy was given to the patient, including stretching, mobilization, strengthening, posture correction, coordination improvement, daily activities, and sports exercises. The therapy was given 5 times a week for the first 5 weeks, then 3 times a week for the next 5 weeks. In all, the intervention lasted for 10 weeks. Results: The patient's senses, posture, and muscular strength all improved to a normal level. The degree of pain fell from 3/10 to 0/10 for activities taking place below shoulder height, and from 8/10 to 1/10 for activities above the head. Additionally, joint integration, motility, range of motion, and movements also improved. The disabilities of the arm, shoulder and hand (DASH) for functional evaluation improved from 27.5 to 10.3. Conclusion: Physical therapy using the PNF concept is effective in improving the body structure, function, activity, and participation of patients with motor disorders of the shoulder impingement syndrome.

Conclusion: This SHTCA applying the nine movement Tai Chi would be helpful on right shoulder flexibility, left shoulder flexibility, right grasping power, left grasping power, abdominal obesity rates and the perception of health status for arthritis patients.
This study is to define how the difference of athletic change influence on the last regrasp after somersault in Belle movement of parallel bars. For his study, the following conclusion was produced by analysis of athletic change by means of three dimensional visual image in three athlete of nation. 1. As the picture of S1, there are total used time(2.01 sec), S3(2.17 sec) and S2(2.19 sec). In case of a short needed time, it is difficult for them to perform the remaining movement of the vertical elevating flight easily and comfortably, it is judged as performing the small movement with restrict swing. 2 In the change of body center sped by each event, it is calculated as $-89.1^{\circ}$ the narrowest in S1, $-81.96^{\circ}$ the widest and then $86.34^{\circ}$ in S3. In E3 event, average compound speed is 4.07m/s, S2 showed the fastest speed of 4.14m/s whereas S1 the narrowest angle of 3.95m/s. 3. A shoulder joint and coxa are the period of mention in E3. In E4 which was pointed out the longest vertical distance, S2 that is indicated the highest vertical height as the period of detach in parallel bars. showed -3.91m. This is regarded as a preparatory movement for dynamic performance after using effectively elastic movement of shoulder joint and coxa while easily going up with turning back movement. In the 5th phrase, long airborne time and vertical change position is showed as the start while regrasping securely air flight movement from high position. 4. In E5, a long flight time and a long vertical displacement were shown as the regrasp after somersault efficiently in high position with stability from the point of the highest peak of the center of the body. Especially, S2 is marked as a little bit long position, while S1 is reversely indicated as performing somersault and unstable motion in a low position. 5. In E3, at the point of the largest extension of the shoulder joint and hip joint the shoulder joint is largely marked in $182^{\circ}$ and the hip point $182^{\circ}$ in S2. The shoulder joint is marked at the smallest angle in $177^{\circ}$ and the hip point $176^{\circ}$ in S1. And S1 is being judged by its performance of the less self - confident motion with lessening a breath of swing. S2 makes the most use of flexion and extension of the shoulder joint and the hip joint effectively. It was performed greatly with swinging and dropping the rotary movement and the rotary inertia naturally. 6. In E6, as the point of regrasp of the upper arm in parallel bars it is recognized by the that of components of vertical and horizontal velocity stably. During this study, the insufficient thing and the study on the parallel bars at a real game later are more activated than now. If it is really used as the basic materials by means of Belle Picked Study of Super E level after Bell movement, you may perceive the technique movement previously and perform without difficulty. Especially, such technique as crucifix is quite advantageous for oriental people thanks to small body shape condition. In conclusion we will nicely prepare for our suitable environment to gradually lessen trials and errors by analyzing and studying kinematically this movement.
Purpose: This study aimed to examine the activity of the shoulder flexor and extensor when hold-relax and contraction-relax techniques were applied with shoulder joint flexion. Methods: The subjects of this study were 15 healthy women. With the shoulder joint flexion at $0^{\circ}$ and $90^{\circ}$, hold-relax and contraction-relax techniques were applied for the same submaximal resistance to measure the activities of the deltoid muscle anterior fiber, deltoid muscle posterior fiber, pectoralis major fiber, and latissimus dorsi muscle with surface electromyography. An independent t-test was conducted in order to compare activities of each muscle according to the two techniques. Results: When the hold-relax and contraction-relax techniques were applied with the shoulder joint flexion at $0^{\circ}$, the activities of the shoulder flexor and extensor were not significantly different, but the activity of the flexor was higher when the contraction-relax technique was applied than when the hold-relax technique was applied. When the hold-relax and contraction-relax techniques were applied with the shoulder joint flexed at $90^{\circ}$, the activities of the shoulder flexor and extensor were not significantly different, but the activity of the extensor was relatively higher than when the flexor was at $0^{\circ}$ Conclusion: When the hold-relax and contraction-relax techniques were applied with the shoulder joint flexion at $0^{\circ}$, the activities of the shoulder flexor and extensor were not significantly different, but the activity of the flexor was higher when the contraction-relax technique was applied than when the hold-relax technique was applied. When the hold-relax and contraction-relax techniques were applied with the shoulder joint flexed at $90^{\circ}$, the activities of the shoulder flexor and extensor were not significantly different, but the activity of the extensor was relatively higher than when the flexor was at $0^{\circ}$.

Objective: There are many cases of applying various taping methods to prevent muscle damage and to assist with movement. The purpose of this study was to investigate and to compare the effects of dynamic taping on joint position sense and to find out the difference in error values during various degrees of shoulder flexion. Design: Cross-sectional study. Methods: A total of 20 subjects participated in this study with a randomized cross-over design. The order of taping was adjusted by randomly proceeding with dynamic taping, sham taping, and no taping. After the taping, the proprioception of the shoulder joint was evaluated. The evaluation of proprioceptive sensation was performed by evaluating joint position sensation. The sequence was adjusted by randomly performing joint position tests at each shoulder flexion of 50, 90, and 110 degrees. All angles were repeated 3 times. Results: There was a significant difference between dynamic taping and no taping in 50 degrees of shoulder flexion. There was a significant difference between sham taping and no taping in 90 degrees of shoulder flexion (p<0.05). No significant difference was found in 110 degrees of shoulder flexion. Conclusions: In this study, it was confirmed that dynamic taping is effective in improving the joint position sense in 50 degrees of shoulder flexion. In the future, it is expected that further studies will be conducted on patients with shoulder dysfunction with decreased proprioception.
