[Purpose] This study aimed to clarify activation of the infraspinatus and scapular stabilizing muscles during shoulder external rotation at various shoulder elevation angles. [Subjects] Twenty subjects participated in this study and all measurements were performed on the right shoulder. [Methods] Isometric shoulder external rotation strength and surface electromyographic data were measured with...

OBJECTIVE To determine variables among glenohumeral elevation and 3-dimensional scapular rotations that are related to shoulder function as assessed by the Disability of the Arm, Shoulder and Hand-Disability/Symptom (DASH-D/S) scale. DESIGN Prospective, cross-sectional study. PATIENTS Eighty-eight patients with shoulder pain and limited range of motion were included. METHODS Each patient ...

in this paper the design, implementation, and evaluation of an experimental-scale potato yield monitoring system is presented. the main objective of this research was to develop a method for accurate mapping of potato yield. at the first stage an instantaneous yield monitoring system was mounted on a potato harvesting machine. this system consisted of a weighing tray, two load cells, a shaft rp...

The occurrence of lateral capsular disruption as a cause of anterior shoulder instability has been reported previously. 1 It was suggested that this injury be considered in patients with instability and no injury or a minimal injury to the glenoid labrum. We now report the occurrence of lateral capsular disruption of the posterior aspect of the shoulder as a cause of pain and weakness. This Les...

BACKGROUND Patients with frozen shoulder who fail conservative therapy need surgical treatment and aggressive post-operative rehabilitation. OBJECTIVE To evaluate the effect of continuous cervical epidural analgesia on pain scores and range of motion of the shoulder joint in patients undergoing surgery for treatment of refractory frozen shoulder. METHODS Twenty-one patients with refractory ...

BACKGROUND The ideal fixation technique for the treatment of proximal humeral fractures remains unclear. In the present study, we evaluated the experience of three surgeons with the treatment of two-part surgical neck fractures with angular-stable intramedullary fixation. METHODS Forty-eight patients with forty-eight Neer two-part surgical neck proximal humeral fractures were managed with loc...

PURPOSE The aim of the study is: 1) to analyse selected features of body posture in women after mastectomy, 2) to compare them with body posture of healthy women, 3) to determine the effect of rehabilitation physical exercises on the changes in body posture in women after mastectomy. MATERIAL AND METHODS The research material consisted of 85 women after mastectomy examined once, including 40 ...

This paper presents a five degrees-of-freedom (DoF) low inertia shoulder exoskeleton. This device is comprised of two novel technologies. The first is 3DoF spherical parallel manipulator (SPM), which was developed using a new method of parallel manipulator design. This method involves mechanically coupling certain DoF of each independently actuated linkage of the parallel manipulator in order t...

We present electrochemical synthesis of super water-repellent poly(alkylpyrrole) films which exhibit excellent environmental stability in terms of contact angle (>150 degrees ) for water. The poly(alkylpyrrole) films synthesized under an optimized electrochemical condition consisted of thousands of micro-scaled 'needles' which densely aligned by shoulder to shoulder. The surface of the aligned ...
