The final aim of this research is to develop a quantitative evaluation system of shoulder joint function using a three-dimensional force display robot. In this paper, we proposed quantitative evaluation methods by which the results equivalent to the results of tests by a therapist can be obtained. The quantitative evaluation methods can be installed in the robot. We focus on two shoulder joint functions. One is stability and the other is cooperativeness. Two experiments were carried out to develop quantitative evaluation methods of shoulder joint function. In the experiments, subject’s forces were measured during the tests by the therapist. On the basis of the experimental results, we proposed a stability evaluation method using a regression equation of glenohumeral joint instability from the ratios between the right and the left subject’s force in the initial position during abduction, external rotation and horizontal abduction motion. Moreover, we proposed a cooperativeness evaluation method by detecting two thresholds related to sustainability of subject’s force.

To promote the demonstration and guidance effect of scenic highway with the project post evaluation, this paper studied the concept of harmony scenic highway and built a Scenic Highway harmony evaluation system which takes highway road area harmony, human road harmony and highway external environmental harmony as core indexes. Scenic highway harmony evaluation method based on interval approximation was adopted to post evaluate typical demonstration scenic highway in Hebei. The practicability of the scenic highway harmony evaluation method based on interval approximation was verified.

Scapular Motion

Proper scapular motion is crucial for normal shoulder mechanics. Scapular motion affects glenohumeral joint function during throwing, yet little is known about this dynamic activity. Asymptomatic subjects (10 male and 10 female), ages 21 to 45, were analyzed. Electromagnetic surface sensors on the sternum, acromion, and humerus were used to collect 3-D motion data during three trials of low-velocity throwing. Scapular angular position data were described for five predetermined events throughout the throw corresponding with classic descriptions of throwing phases, and trial-to-trial reliability was determined. ANOVA compared scapular angles across events. Subjects demonstrated good to excellent reliability between trials of the throw (ICC 0.74–0.98). The scapula demonstrated a pattern of external rotation, upward rotation (peak of approx. 40°), and posterior tilting during the initial phases of the throw, progressing into internal rotation after maximum humeral horizontal abduction. During the arm acceleration phase, the scapula moved toward greater internal rotation and began anteriorly tilting. At maximum humeral internal rotation, the scapula ended in internal rotation (55°), upward rotation (20°), and anterior tilting (3°).

Background: Extension of the elbow joint is maintained during shoulder flexion. In contrast, the arm starts from the flexed position of the elbow joint and the joint gradually extends during reaching elevation. Objectives: This study aimed to compare the kinematic elements and electromyographic (EMG) activities of the rotator cuff muscles between flexion and reaching elevation. Methods: The study included 10 healthy young men. (average age, 21.5 ± 3.4 years), and measurements were performed on their dominant arms. A three-dimensional motion analyzer was used to record the following elements during shoulder flexion and reaching elevation: the angles of glenohumeral joint elevation and scapular upward rotation, scapulohumeral rhythm, external rotation of the humerus, and glenohumeral plane shifting from the coronal plane. The EMG activities in the supraspinatus, infraspinatus, subscapularis, and teres minor were recorded simultaneously. Results: The plane of reaching elevation was retained at 60° from the coronal plane. The glenohumeral planes (P < 0 .01) and the external rotation angles of the humerus below 90° of elevation (P < 0.05) were significantly different between both the motions. The EMG activities in the supraspinatus (P < .01), infraspinatus (P < 0.05), and teres minor (P < 0.01) were significantly lower while reaching elevation than those during flexion. Conclusion: The motion plane at 60° from the coronal plane, movement of the humeral external rotation, and EMG activities of the rotator cuff muscles were different during reaching elevation and shoulder flexion.
