abstract a 2.5 year old girl is presented with both hands constriction bands leading to distal amputations and the rare deformity of shoulder duplication in the right side accompanying constriction skin marking over the affected shoulder. the cephalomedial scapula articulated with the clavicle and the caudolateral scapula articulated with humeral head. the most important physical finding which ...

background: there are some challenges about the role of work- related stress on development of musculoskeletal complaints. the present prospective study was conducted on nurses of milad hospital in tehran (iran) to assess the role of work- related stress on development of neck and shoulder pain among nurses.   methods: from the 1,900 nurses who completed the registry forms, 1,450 nurses met the...

a hydatid cyst is a zoonotic infection caused by the larval forms of mostly the echinococcus granulosus. in humans, the most common site of cyst development is the liver (60%), followed by the lungs (20%), and much less commonly in other organs such as kidney, spleen, brain, and other soft tissues. the localization of cysts in muscles and subcutaneous is very rare. we report a case of 38-year-o...

A simple upper limb control strategy to guide reaching in preparation to grasp for tetraplegic subjects is proposed. The control is based on new studies of self-paced human arm movements involving rotations about the shoulder and elbow joints. An experimental study of reaching, while grasping, by able-bodied humans, allowed us to reduce the dimensionality of the control vector from two to a sin...

"Acromion" is one of many anatomical terms derived from ancient Greek: it is a transliteration of the Greek word dxp ptov (akromion). For the modern anatomist "acromion" has a precise meaning: "The lateral extension of the spine of the scapula, forming the highest point of the shoulder."'

We investigated the control and function of arm swing in human walking and running to test the hypothesis that the arms act as passive mass dampers powered by movement of the lower body, rather than being actively driven by the shoulder muscles. We measured locomotor cost, deltoid muscle activity and kinematics in 10 healthy adult subjects while walking and running on a treadmill in three exper...

Twelve collegiate football quarterbacks were videotaped while performing drop back passes. The video images were digitized using a Peak Performance system, and three-dimensional (3-D) kinematic and kinetic data were calculated from the 3-D coordinate data using standard analytical procedures. The sequential timing of peak shoulder torques in the delivery for the football throw was peak abductio...
