Background: Although visual examination and palpation are used to assess shoulder motion in clinical practice, there is no consensus on shoulder motion under dynamic and static conditions. This study aimed to compare shoulder joint motion under dynamic and static conditions. Methods: The dominant arm of 14 healthy adult males was investigated. Electromagnetic sensors attached to the scapular, thorax, and humerus were used to measure three-dimensional shoulder joint motion under dynamic and static elevation conditions and compare scapular upward rotation and glenohumeral joint elevation in different elevation planes and angles. Results: At 120° of elevation in the scapular and coronal planes, the scapular upward rotation angle was higher in the static condition and the glenohumeral joint elevation angle was higher in the dynamic condition (P<0.05). In scapular plane and coronal plane elevation 90°-120°, the angular change in scapular upward rotation was higher in the static condition and the angular change in scapulohumeral joint elevation was higher in the dynamic condition (P<0.05). No differences were found in shoulder joint motion in the sagittal plane elevation between the dynamic and static conditions. No interaction effects were found between elevation condition and elevation angle in all elevation planes. Conclusions: Differences in shoulder joint motion should be noted when assessing shoulder joint motion in different dynamic and static conditions.

Purpose: This study aimed to investigate changes in upper extremity joints and leisure satisfaction in children with brain lesions through sports stacking activities. Methods: A sports stacking program was conducted on three children with brain lesions who had upper extremity joint limitations and joint range of motion lower than the normal range. It was conducted 10 times, 1 to 2 times a week, 40 minutes each time. Upper extremity joint angles were measured using a goniometer in the order of shoulder, elbow, wrist, and fingers, and leisure satisfaction was measured using a smile evaluation. Results: As a result of measuring the upper extremity joint angles, all three children showed slight angle changes in the shoulder, elbow, and wrist areas. Differences in joint angles appeared differently for each child. Smile evaluation results were evaluated in various psychological, educational, and physical aspects. Only child A was evaluated for Smile Evaluation No. 1. Conclusion: Sports stacking activities changed the upper extremity function of children with brain lesion disorders and showed differences in psychological, physical, and educational aspects of leisure satisfaction. As this is a short-term study result, the change in upper extremity function is minimal, but if sports stacking activities are continued, it will be a rehabilitation program that can prevent upper extremity dysfunction and improve physical strength. Accordingly, continuous attention should be paid to increasing accessibility and enjoyment of daily life according to individual characteristics and level.

This paper presents a portable tele-assessment system designed for remote evaluation of the hypertonic elbow joint of neurologically impaired patients. A patient's upper limb was securely strapped to a portable limb-stretching device which is connected through Internet to a portable haptic device by which a clinician remotely moved the patient's elbow joint and felt the resistance from the patient. Elbow flexion angle and joint torques were measured from both master and slave devices and bilaterally fed back to their counterparts. In order to overcome problems associated with the network latency, two different tele-operation schemes were proposed depending on relative speed of tasks compared to the amount of time delay. For slow movement tasks, the bilateral tele-operation was achieved in real-time by designing control architectures after causality analysis. For fast movement tasks, we used a semi-real-time tele-operation scheme which provided the clinicians with stable and transparent feeling. The tele-assessment system was verified experimentally on patients with stroke. The devices were made portable and low cost, which makes it potentially more accessible to patients in remote areas.

This study is to compare muscle strength between isotonic exercise and isotonic & isokinetic exercise. Participants are 12-man and 10-woman whom they are healthy without medical history in shoulder, elbow and lumbar joint. We performed experiment total 4-weeks that exercise 3-days a week each exercise pattern. We measured shoulder, elbow and lumbar joint torque with BIODEX and circumference of muscle in upper arms once a week. The result showed that isotonic & isokinetic exercise pattern significantly more improved joint torque in shoulder, elbow, lumbar than isotonic exercise pattern. Because that isotonic & isokinetic exercise pattern supplied muscle strengthen and caused muscle contraction. This exercise pattern can be used new exercise training method for major athlete and normal people. Also this pattern can be used rehabilitation treatment.

Repair of the rotator cuff tear is a joint-tightening procedure that can worsen joint stiffness. This paradoxical phenomenon complicates treatment of rotator cuff tear with joint stiffness. As a result, there is controversy about how and when to treat joint stiffness. As many treatments have been published, this review discusses the latest findings on treatment of rotator cuff tear with joint stiffness.

The purpose of this study was to establish reliability of the Tone Assessment Scale (TAS) translated into Korean in patients with stroke. The TAS consists of resting posture, response to passive movement, and associated reaction to active effort. Fifteen patients (14 males, 1 female) were examined by two raters. Surface electromyography (EMG) data at elbow flexor muscle and joint excursion were collected from 6 patients. To identify the correlation between muscle activity and angular changes of elbow muscle, Pearson product moment correlation was used. The inter-rater and intra-rater reliability of the TAS ranged from very good to good (K/Kw=.61~1.00 for intra-rater and K/Kw=.73~1.00 for intra-rater comparisons) in the sections of resting posture and associated reaction. However, in the section of response to passive movement, the reliability coefficients ranged from very good to fair (Kw=.29~1.00). In the 11th item, correlation between EMG ratio of elbow flexor and angular changes of elbow joint showed statistically strong positive relationship (r=.94, p<.05). These results indicate that the TAS is selectively reliable in the sections of resting posture and associated reaction.

Background: Rotator cuff tears are often associated with synovitis, but the ability of noninvasive ultrasonography to predict the severity of synovitis remains unclear. We investigated whether ultrasound parameters, namely peak systolic velocity in the anterior humeral circumflex artery and Doppler activity in the glenohumeral joint and subacromial space, reflect synovitis severity. Methods: A total of 54 patients undergoing arthroscopic rotator cuff repair were selected. Doppler ultrasound was used to measure peak systolic velocity in the anterior humeral circumflex artery and Doppler activity in the glenohumeral joint and subacromial space, and these values were compared with the intraoperative synovitis score in univariate and multivariate analyses. Results: Univariate analyses revealed that tear size, peak systolic velocity in the anterior humeral circumflex artery, and Doppler activity in the glenohumeral joint were associated with synovitis in the glenohumeral joint (P=0.02, P<0.001, P=0.02, respectively). In the subacromial space, tear size, peak systolic velocity in the anterior humeral circumflex artery, and Doppler activity in the subacromial space were associated with synovitis severity (P=0.02, P<0.001, P=0.02, respectively). Multivariate analyses indicated that tear size and peak systolic velocity in the anterior humeral circumflex artery were independently associated with synovitis scores in both the glenohumeral joint and the subacromial space (all P<0.05). Conclusions: These findings demonstrate that tear size and peak systolic velocity in the anterior humeral circumflex artery, which can both be measured noninvasively, are useful indicators of synovitis severity.
