BACKGROUND AND PURPOSE In people with stroke, range-of-motion (ROM) exercises may contribute to hemiparetic shoulder pain, but the underlying mechanisms are unknown. This study examined scapular and humeral movement patterns in people with poststroke hemiparesis as they performed commonly prescribed ROM exercises. METHODS Using kinematic techniques, we studied 13 people with hemiparesis, both...

concrete and simple-complex. The first involves the position a given concept should occupy in the spiral movement from abstract to concrete along one plane of analysis. The second type of movement concerns the combination of different planes of analysis. The greater the number of planes of analysis which are articulated, the more complex is the analysis. This second movement is particularly rel...

Shoulder musculoskeletal disorders are among the most prevalent work-related musculoskeletal disorders and constitute an important health problem. One of the occupations that are most affected is workers on assembly lines (Leclerc et al., 2004), as these jobs requires repetitive movement, which, as a risk factor, has been found positively associated with shoulder disorders. Repetitive movement ...

This paper aims to investigate whether micro-facial movement sequences can be distinguished from neutral face sequences. As a micro-facial movement tends to be very quick and subtle, classifying when a movement occurs compared to the face without movement can be a challenging computer vision problem. Using local binary patterns on three orthogonal planes and Gaussian derivatives, local features...

In this paper data are presented concerning the motion of limb segments during drawing movements executed in different planes in free space. The technique used allows the determination of the wrist and elbow positions in space as well as the measurement of the elbow angle of extension. Other kinematic variables are determined trigonometrically. Elbow and shoulder torque is also calculated. For ...

  Frozen shoulder is a glenohumeral joint disorder that perturbs movement because of adhesion and the existence of fibrosis in the shoulder capsule. Platelet-rich plasma can produce collagen and growth factors, which increases stem cells and consequently enhances the healing. To date, there is no evidence regarding the effectiveness of platelet-rich plasma in frozen shoulder. A 45-year-old man ...

The empty can (EC) and full can (FC) tests are used as diagnostic tools for patients with rotator cuff disease. However, recently concerns have been raised that these tests do not selectively activate the muscle. Therefore, the purpose of this study was to evaluate the rotator cuff muscle activation levels during the EC and FC tests in various positions using electromyography. Twelve healthy, r...

To predict neuromuscular disorders, we are interested in monitoring upper limb movements continuously using wearable sensors. Shoulder muscle coordination is complex and for those with neuromuscular disorders, this coordination often fails. As monitoring the entire kinematics of the shoulder complex is nearly impossible to do continuously, we propose to simply track the humerus and clavicle ang...

The contribution deals with the optimization of the EEG off-line, single-trial movement classification by means of parameterization tuning. The data we classify represent manifestations of the simple movements performed by the right shoulder (proximal movement) and right index finger (distal movement) of experimental subjects. We implemented several approaches to the EEG parameterization and co...
