  • Background: Limitations of shoulder range of motion (ROM), particularly shoulder internal rotation (SIR), are commonly associated with musculoskeletal disorders in both the general population and athletes. The limitation can result in connective tissue lesions such as superior labrum tears and symptoms such as rotator cuff tears and shoulder impingement syndrome. Maintaining the center of rotation of the glenohumeral joint during SIR can be challenging due to the compensatory scapulothoracic movement and anterior displacement of the humeral head. Therefore, observing the path of the instantaneous center of rotation (PICR) using the olecranon as a marker during SIR may provide valuable insights into understanding the dynamics of the shoulder joint. Objects: The aim of the study was to compare the displacement of the olecranon to measure the rotation control of the humeral head during SIR in individuals with and without restricted SIR ROM. Methods: Twenty-four participants with and without restricted SIR ROM participated in this study. The displacement of olecranon was measured during the shoulder internal rotation control test (SIRCT) using a Kinovea (ver. 0.8.15, Kinovea), the 2-dimensional marker tracking analysis system. An independent t-test was used to compare the horizontal and vertical displacement of the olecranon marker between individuals with and without restricted SIR ROM. The statistical significance was set at p < 0.05. Results: Vertical displacement of the olecranon was significantly greater in the restricted SIR group than in the control group (p < 0.05). However, no significant difference was observed in the horizontal displacement of the olecranon (p > 0.05). Conclusion: The findings of this study indicated that individuals with restricted SIR ROM had significantly greater vertical displacement of the olecranon. The results suggest that the limitation of SIR ROM may lead to difficulty in rotation control of the humeral head.

  • Background: Patients who have rotator cuff arthropathy experience a limited range of motion (ROM) of the shoulder joint and experience problems in performing their daily activities; however, no evidence is available to suggest the exact ROM of the shoulder joint in this population. Therefore, this study sought to determine the degree of motion of the shoulder joint in three planes during different activities. Methods: Five subjects with rotator cuff injuries participated in this study. The motion of the shoulder joints on both the involved and normal sides was assessed by a motion analysis system while performing forward abduction (task 1), flexion (task 2), and forward flexion (task 3). The OpenSIM software program was used to determine the ROM of the shoulder joints on both sides. The difference between the ranges of motion was determined using a two-sample t-test. Results: The ROMs of the shoulder joint in task 1 were 93.5°±16.5°, 72.1°±2.6°, and 103.9°±25.7° for flexion, abduction, and rotation, respectively, on the normal side and 28°±19.8°, 31°±31.56°, and 48°±33.5° on the involved side (p<0.05). There was no significant difference between the flexion/extension and rotation movements of the shoulder joint when performing task 1. However, the difference between flexion and rotation movements of the shoulder joints for the second task was significant (p>0.05). Conclusions: Those with rotator cuff arthropathy have functional limitations due to muscle weakness and paralysis, especially during the vertical reaching task. However, although these individuals have decreased ROM for transverse reaching tasks, the reduction was not significant.

  • PURPOSE: The purpose of the study was to investigate a influence in Proprioceptive Neuromuscular Facilitation, and self-assisted ROM exercise of shoulder adhesive capsulitis. METHODS: The methods of the study was to investigate a change in range of motion (ROM), an increase in ROM, visual analogue scale (VAS) and disability questionnaire by Proprioceptive Neuromuscular Facilitation, and self-assisted ROM exercise on 32 patients who were diagnosed with shoulder adhesive capsulitis. RESULTS: There was no significant difference between the two groups who were treated in the Proprioceptive Neuromuscular Facilitation and self-assistive ROM exercise group for flexion, extension, internal rotation, external rotation, VAS and disability questionnaire. Both group's flexion, extension, internal ratation, and external rotation levels were significantly different before and after the treatment. And significant statistical decrease in VAS and disability was seen. The extension of the shoulder joint was closely related to external rotation (r=0.84). There was a close relationship between internal rotation and external rotation at the shoulder joint. There was no increased range of extension through the exercise method. However, flexion, extension, internal rotation, external rotation, VAS, and disability questionnaire of Proprioceptive Neuromuscular Facilitation groups were obviously higher than in the self-assisted ROM exercise group. CONCLUSION: Our study suggest that considering Proprioceptive Neuromuscular Facilitation for the patient who has shoulder adhesive capsulitis in clinic.

  • A single subject experimental design (alternating treatment design) was used to compare the effects of only ultrasound and ultrasound combined with stretching of the joint capsule on the ROM increase and pain reduction in patients with frozen shoulder. Two subjects were included in each group. In the only ultrasound treatment sessions, ultrasound was applied at the pain point of the shoulder joint in supine position. In the ultrasound combined with stretching treatment sessions, ultrasound was applied at the pain point of the shoulder joint positioned in external rotation and abduction in sitting position. Only ultrasound treatment and ultrasound combined with stretching treatment were alternately performed on each patient. Pain and disability was measured by shoulder pain and disability index (SPADI), and range of motion (ROM) was measured by scratch test. The results of this study showed that ultrasound combined with stretching treatment were more effective than only ultrasound treatment in ROM increase and pain reduction. However, disability score was not significantly different.

  • Background: Posterior shoulder tightness, which is a problem mainly seen in patients with shoulder impingement syndrome, disrupts the scapulohumeral rhythm between the humerus and scapulae. Objects: The aim of this study was to compare the effects of joint mobilization and stretching on shoulder muscle activity and internal rotation range of motion (ROM) of the glenohumeral joint in patients with impingement syndrome with posterior shoulder tightness. Methods: The research subjects included 22 in-patients with impingement syndrome with posterior shoulder tightness. They were randomly divided into two groups: one group (12 patients) was treated with joint mobilization and the other group (10 patients) was treated with stretching for the posterior shoulder tightness. Each treatment was performed five times a week for two weeks, and there were 15 sessions for each treatment. The ROM of the internal rotation and muscle activities of shoulder joint were evaluated pretest and posttest in each group. Electromyography data were collected from the upper, middle, and lower trapezius and serratus anterior during shoulder abduction of 90°, 120°, and 150°. Results: Both the joint mobilization and stretching groups showed significant decreases in muscle activity in the upper, middle, and lower trapezius on the posttest (p < 0.05). There was a significant difference in serratus anterior at 150° (p < 0.05), but there was no significant difference between group in post-hoc analysis (p > 0.025). The internal rotation ROM was significantly increased in the stretching group compared to that in the joint mobilization group (p < 0.025). Conclusion: This study found that both joint mobilization and stretching for posterior shoulder tightness were effective in muscle activity during arm abduction, also in order to increase internal rotation ROM of shoulder joint, stretching was effective in patients with impingement syndrome with posterior tightness.

  • We investigated the biomechanics and characteristics of shoulder rotator muscles for professional woman volleyball players. The purpose of this study was to analyze the isokinetic peak torque and range of motion for shoulder joint rotation. We measured the strength and ROM of the internal rotation(IR) and external rotation(ER) of shoulders joint for nine professional woman Volleyball players and nine University students with Biodex and Simi-motion. 1. We measured peak torques for the shoulder joint rotator at angular velocities of 60/s and 180/s. It was found that the peak torques were significantly different between the two groups and also between the hands used. 2. At angular velocity of 60/s, IR/ER ratio of the shoulder joint was significantly different depending on the groups and the hands in use. There was a significant difference for 'Dominant side' at angular velocity of 180/s, but no significant difference for 'Non-dominant side' and the controls group. 3. Regarding the ROM of rotation of the shoulder joint group, IR was significantly different between the groups and the hands in use. 4. IR/ER ratio of the shoulder joint for Dominant side was quite different between the groups.

  • 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.

  • 본 연구는 관절가동술 후 두 가지 유형의 전기치료 방법을 각각 적용하였을 때 유방암 환자의 어깨 가쪽돌림 가동범위와 통증에 미치는 효과를 알아보기 위해 실시하였다. 유방절제술을 시행한 유방암 환자 30명을 STMG (관절가동술+비침습적 무통증 신호 전기치료) 15명과 TENMG (관절가동술+경피신경전기자극) 15명으로 나누었다. 중재는 4주간 주 3회, 1회당 1시간씩 실시하였다. 측정은 어깨 가쪽 돌림 관절가동범위(Range of motion, ROM), 통증(Visual analog scale)을 측정하였다. 중재 전·후 두 군 모두 어깨 가쪽돌림 관절가동범위, 통증에서 유의한 차이가 있었다(p<.05). STMG는 어깨 가쪽 돌림 관절가동범위를 제외하고 TENMG보다 통증 감소에서 더욱 효과적이었다(p<.05). 유방암 절제술 환자의 통증을 경감시키기 위해서는 STMG이 TENMG보다 더욱 효과가 있다는 것을 확인할 수 있었다. 다양한 차이를 확인하기 위해 대조군을 더하고, 더 많은 대상자가 필요할 것으로 사료된다.

  • Background: Patients after rotator cuff (RC) surgery experienced pain, weakness and limited of motion of the shoulder. Physical therapists have used heat therapy, electrotherapy, range of motion (ROM) exercise and other methods to treat patients after RC surgery. In addition, functional taping is also used to support joint movement and to increase shoulder joint stability. Objects: The purpose of this study was to determine the initial effects of functional taping using non-elastic tape on pain, strength and ROM of the shoulder following RC surgery. Methods: Forty-eight patients with who underwent RC surgery volunteered for this study. The subjects were randomly divided into an experimental group (EG, $n_1=25$) and a control group (CG, $n_2=23$). First, non-allergic tape was applied to the shoulder to prevent skin irritation. The EG applied functional taping using non-elastic tape and the CG applied sham taping using elastic tape. Assessment tools included the shoulder pain and disability index for functional activity score, visual analog scale for level of pain, shoulder muscle strength, hand grip strength and ROM testing. Results: Pain score in the both group significantly decreased (p<.05), and change in pain score of in the EG increased significantly than in the CG (p<.05). Shoulder strength and ROM in the both group significantly increased (p<.05). Especially external rotation and extension of the shoulder ROM in the EG increased significantly more than in the CG (p<.05), but the rate of change in the two groups showed no significant difference. Conclusion: These results suggest that functional taping using non-elastic tape was initially effective in decreasing pain score level in patients with RC surgery.

  • Purpose: This study examined the effects of early stabilization exercise focused on the scapulothoracic joint on the recovery of surgical patients due to rotator cuff tear. Methods: The subjects were 30 patients divided randomly into two groups. Group I consisted of 15 patients who practiced shoulder joint stabilization exercises, including glenohumeral joint movement. Group II consisted of 15 patients who practiced scapulothoracic joint stabilization exercises, excluding glenohumeral joint movement. The duration of stabilization exercise was 30 minutes for one day, five days a week, and five weeks. To measure the dependent variables, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, range of motion (ROM), dynamometer of measured grip were used. Results: The DASH, ROM, and grip power were compared. A significant difference was observed before the intervention in each group (p<.05), and there was no significant difference between group I and group II (p>.05). Conclusion: Both shoulder joint and scapulothoracic joint stabilization exercises were effective after the intervention compared to preintervention, but there was no difference between the two groups. Unlike many recent studies on the initiation of stabilization exercises, this study allays the concerns between the advantages of 'early exercise' and oppositions of previous studies about 'early exercise'. Nevertheless, further research regarding these subjects is needed.
