The purpose of this study was to compare the effects of Mulligan method and PNF method on the pain and limitation of range of motion in patients with frozen shoulder. The subjects of this study were 20 patients, 10(50%) males and 10(50%) females. They visited clinic for physical treatment within 6 months after onset of shoulder pain and limitation of range of motion with frozen shoulder. One group was applied with Mulligan method and other group was with PNF method. The patient were treated 5 times session weekly for 6 weeks from March 4th, 2002. And each treatment session was 15min. with physiotherapy. The pain was measured by visual analogue scale (V AS) and rage of motion (ROM) of flexion, abduction, external rotation, internal rotation were measured by goniometer. The data was analysed by paired T-test and independent T-test. The results of this study were summarized as follow : 1. The ROM of Mulligan method group increase in after treatment in comparison with ROM in before treatment, it is significant increase. Although the V AS of MMG decrease in before than after treatment, it is significant difference. 2. There is significant difference in before and after treatment of ROM of shoulder flexion, abduction, internal rotation, external rotation between PNF method group. The V AS of PMG is decreasing in before than after treatment, it is significant difference. 3. There is significant difference in before movement and after movement ROM of flexion, abduction, internal rotation, external rotation and VAS between Mulligan method session and PNF method session then the scale which measured by Mulligan method was more increased than that of PNF method. The results showed that both Mulligan method and PNF method were effective in pain reduce and ROM increase, but Mulligan method was superior to PNF method in ROM increase and pain reduce.

Purpose: The purpose of this study is to evaluate the relationship between trochlear medial facet osteophyte (TMFO) and elbow flexion in the elbow joints without trauma history. Materials and Methods: Twenty five patients, who underwent computed tomography without elbow trauma history, were reviewed. Patients were checked for osteophyte or loose bodies in the coronoid and olecranon sides. The height and length of TMFO were measured. Results: The average elbow flexion contracture was $18.6^{\circ}$, and further flexion was $112.1^{\circ}$. The TMFO height and length was 2.2 mm and 4.7 mm, respectively. The average elbow further flexion was $105.1^{\circ}$ in the coronoid block group (n=14) and $119.1^{\circ}$ (p=0.011) in the coronoid free group (n=11). The relationship between further elbow flexion and TMFO was significant with a partial correlation coefficient of 0.687(p<0.000) in the TMFO length. Conclusion: Elbow joints with longer TMFO length decrease further flexion.

Objective: The objective of this research is to quantitatively analyze muscle activities of arm and shoulder, according to direction in various types of one-handed manual material handling, based on surface electromyography. Background: Workers in industrial sites frequently carry out one-handed manual material handling using arm and shoulder muscles. Therefore, chronic load and accumulated fatigue occur to arm and shoulder muscles, which becomes a main cause of upper arm and shoulder musculoskeletal disorders. The shoulder muscles have widely range of motion, and complex interactions take place among various muscles including rotator cuff muscles. In this regard, research on interactions among should muscles, according to such various dynamic motions, is required. Method: Ten male subjects in their 20s participated in this research. This research considered upward, downward, leftward, rightward, forward and backward directions and fourteen muscles around arm and shoulder (biceps brachii and trapezius, etc.) as independent variables. The mean muscle activity was set as the dependent variable. This research extracted $4^{th}{\sim}7^{th}$ repetition signals according to ten times of repetitive muscle contraction, and analyzed the muscle activity concerned using the envelope detection technique. Results: The mean muscle activity of upward direction was analyzed highly statistically significant. The reason is that the effect of gravity works to arm and shoulder muscles. Also, it is conjectured that deformation of coracoacromial ligament was caused, and its contact pressure increased, due mainly to the shoulder flexion, and therefore load was analyzed high. Muscle activity was analyzed significantly low, according to concentric ballistic motion used in the concentric contraction phase by storing elastic energy in the eccentric contraction phase with a motion to bring the weight to the front of subject's body as to downward, leftward and backward directions. Because, elbow joint's flexion-extension motions mainly occurred, biceps brachii was analyzed high muscle activity as the prime mover. Conclusion: The information on the quantitative load of muscles can be applied to ergonomic work design for one-handed manual material handling to minimize muscle load. Application: This research has effectively identified muscle activity according to dynamic contraction by applying an envelope detection technique. The results can be used for ergonomic work design to minimize muscle load during the one-handed manual material handling, according to each direction. The research results are expected to be used for musculoskeletal disorder prevention and physiotherapy in the rehabilitation medical field, based on the muscle load of arm and shoulder in various directions.

Objectives The purpose of this study was to observe effectiveness of ultrasound-guided Soyeom pharmacopuncture therapy at acromioclavicular joint of shoulder in patients with anterior shoulder pain. Methods We analyzed medical records of 9 patients hospitalized with anterior shoulder pain who had admitted to Department of Korean Rehabilitation Medicine, College of Korean Medicine, Daejeon University from March 1, 2021 to June 13, 2021. 9 patients were treated the treatment of Soyeom pharmacopuncture therapy on acromioclavicular joint under ultrasonic guidance with Korean medicine treatment (such as herbal medicine, acupuncture, moxabustion, etc). The study was conducted as a retrospective observation study which analyze the patient's medical records. We used numeric rating scale (NRS) to evaluate pain reduction and the shoulder range of motion (ROM) to evaluate function improvement twice (before pharmacopuncture treatment and 5 days later treatment). Statistical analysis was performed using the IBM SPSS Statistics version 25 program (IBM Co., Armonk, NY, USA). Results The average of numeric rating scale reduced statistically significantly from 5.56±1.13 to 3.11±1.36 (p=0.004). The average of shoulder flexion ROM increased statistically significantly from 166.67±8.17° to 175.00±8.37° (p<0.05). And the average of shoulder abduction ROM increased statistically significantly from 158.57±20.35° to 172.86±12.53° (p<0.05). Both NRS and shouler ROM showed statistically significantly improve after treatment. Conclusions This study shows ultrasound-guided Soyeom pharmacopuncture therapy at acromioclavicular joint of shoulder has a meaningful clinical effect on the improving shoulder pain and ROM especially on flexion and abduction.

The purpose of this study was to examine the difference in measurements of passive range of motion(PROM) of shoulder when motions are assessed in sitting, as compared with supine and the intratester and intertester reliabilities for goniometric measurements of shoulder PROM using two different sizes of goniometers. * A thesis submitted to the committee of Graduate School of Public Health, Chungnam National University in partial fulfillment of the requirements for the degree of Master of Public Health conferred in February 2001. Fifty one adult male subjects were measured three times, in random order, for the six shoulder motions(flexion, extension, abduction, adduction, external rotation, and internal rotation) while sitting and supine by three different therapists. Data were analyzed to determine intraclass correlation coefficients (ICCs) and paired "t" values between trials for measurements with different goniometer and betweensitting and supine trials. There was statistical difference in measurement of shoulder motion between supine and sitting position and no statistical difference in goniometric type. The intratester intraclass correlation coefficients (ICCs) for all motions ranged from .87 to .98. The ICCs for the intertester reliability of PROM measurements of all shoulder motion ranged from .26 to .89. These findings suggest that reliable measures of PROM of the shoulder can be obtained using standard goniometry in a proper position.

Background: The serratus anterior and upper trapezius muscles act synergistically to allow for an appropriate scapulothoracic rhythm. However, a decrease in serratus anterior activation causes the upper trapezius to become overactivated, resulting in dysfunction. This study compared serratus anterior and upper trapezius muscle activity according to sling angle and compared serratus anterior strength between healthy adults and patients with shoulder instability. Methods: Twenty participants (10 healthy adults and 10 patients with shoulder instability) were included in this study. The participants had their arms extended at sling angles of 30°, 60°, and 90° in reach forward with shoulder flexion using goniometer. Serratus anterior strength was measured three times while the participants were supine. The outcome measures were surface electromyography amplitude of the upper trapezius and serratus anterior and serratus anterior strength. Results: The Wilcoxon signed-rank test indicated that the upper trapezius was significantly different between healthy group and shoulder instability group at a sling angle of 60°, and both the upper trapezius and serratus anterior exhibited significant differences at 90°. Moreover, a significant difference was noted in the muscle strength of the serratus anterior. Conclusion: Our results provide novel and promising clinical evidence that patients with shoulder instability have decreased serratus anterior activation and upper trapezius overactivation, resulting in muscle imbalance. In addition, there was a significant difference between the healthy group and shoulder instability group in the serratus anterior muscle strength

The present study provides reference data required for the design of clothing for the elderly by analyzing the body surface area during fitness motion based on 3D scan data of Korean elderly women. This study was conducted with the procedures of (1) survey of motions and main muscles for fitness, (2) acquisition of 3D scan data, and (3) analysis of rate of change for body surface area during fitness motion. Acquisition of 3D body scan data was obtained from seven elderly females (age: 64-77). We selected 66 anatomical landmarks (40 upper body and 22 lower body) by referring to previous studies. Body surface was segmented by connecting the landmarks marked on the 3D scan data acquired. Analysis of body surface area was conducted in terms of the change rate of surface area in 9 postures of elbow 0°, 90° and 180° for flexion, shoulder 90°, 180° for flexion, shoulder 0°, 180° for abduction, hip 90° for flexion, and knee 90° for flexion compared to the those in the standing posture. The amount of changes in body surface area were 12%-62% in the upper body, 15%-77% in the arm, and 10%-51% in the lower body. A future study on the rate of change of body surface length is needed; in addition, a study on how to apply the results of body surface area and body surface length analysis to clothing pattern design is also necessary.

Background: The purpose of this study is to evaluate the functional outcomes of reverse total shoulder arthroplasty (RTSA) and to assess factors affecting the patients' subjective satisfaction after RTSA. Methods: Forty-three patients (mean age, $75.0{\pm}5.2years$) who underwent RTSA for cuff tear arthropathy or irreparable cuff tears with preoperative magnetic resonance imaging and pre- and postoperative radiographs at 1 year, and whose various functional outcomes including pain visual analogue scale (VAS), simple shoulder test, Constant score, American Shoulder and Elbow Surgeons score, and active range of motion were evaluated preoperatively and at the last follow-up (>12 months) were enrolled. The outcome parameter was set as a satisfaction scale. Various clinical and radiographic factors were analyzed, and their correlations with postoperative satisfaction were evaluated. Results: All functional scores, VAS pain score, and active forward flexion showed significant improvement after surgery (all p<0.001). Twenty-nine patients were satisfied with the results and 14 were dissatisfied. The presence of pseudoparalysis (p=0.028) and worse preoperative function (all p<0.05) were related with higher satisfaction. Any radiologic parameters did not affect patients' postoperative satisfaction. Conclusions: All patients showed a good functional outcome after RTSA, however the patients' subjective postoperative satisfaction was affected by preoperative functional status (higher satisfaction in poor preoperative function), not by radiological findings.
