The purpose of this study was to develop regression equations predicting torque output throughout the range of motion for the human elbow, shoulder, knee, and hip. Twenty-two healthy males participated. Torque values throughout the sagittal plane range of motion (i.e., flexion and extension) of the right elbow, shoulder, knee and hip were recorded (isokinetic dynamometer, 1 rad/sec) and express...

Since its discovery, our understanding of the primary motor cortex has continued to evolve. The presentations of rare, isolated, motor palsies of small muscle groups have heavily contributed to the characterization of the somatotopic representation of the human body on the cortex. We present a case of localized, left shoulder small muscle group weakness secondary to ischemic cerebral infarction...

Human joints, such as the shoulder, present intricate connections of anatomical elements such as bones, muscles, tendons, ligaments, and fat. The nature and arrangement of the various structures in the shoulder impose two main difficulties for interactive simulation: a large diversity of mechanical properties, ranging from hard bone to soft fat tissue, and complex contact situations. In this pa...

OBJECTIVE To explore relationships between shoulder complaints after neck dissection, shoulder disability, and quality of life. To find clinical predictors for mid- to long-term shoulder disability. STUDY DESIGN Prospective. PATIENTS AND METHODS Shoulder pain, shoulder mobility, and shoulder droop, as well as scores on shoulder disability questionnaire and RAND-36 (quality of life), were me...

CONTEXT The overhead throwing motion is complex, and restrictions in range of motion (ROM) at the hip may place additional demands on the shoulder that lead to injury. However, the relationship between hip and shoulder ROM in athletes with and without a history of shoulder injury is unknown. OBJECTIVE To (1) determine if differences exist in hip and shoulder ROM between professional baseball ...

conclusions bilateral anterior shoulder dislocation is very rare. the excessive traction force during closed reduction may lead to nerve palsy. clear documentation of neurovascular status and adequate imaging before and after a reduction should be performed. introduction unilateral anterior shoulder dislocation is one of the most common problems encountered in orthopedic practice. however, simu...

The transverse rotations of the human pelvis and shoulder girdle duiing walking were studied and compared in 10 young men and 10 young women. Three sets of measurements were made for each subject : transverse rotation of the pelvis, transverse rotation of the shoulder girdle, and simultaneous transverse rotations of the pelvis and the shoulder girdle . All measurements were made while the subje...

This paper concerns the different ways in which hesitation, and hesitation related phenomena like uncertainty, doubt and lack of knowledge are expressed in different cultures. The paper focuses especially on shoulder shrugging as a signal of hesitation or uncertainty, and starts from the observation that shoulder shrugging has different interpretations depending on the interlocutor’s cultural c...
