Analyzing At -Home Prosthesis Use in Unilateral Upper -Limb Amputees to Inform Treatment & Device Design Adam J. Spiers, Member, IEEE, Linda Resnik, and Aaron M. Dollar, Senior Member, IEEE Abstract — New upper limb prosthetic devices are continuously being developed by a variety of industrial, academic, and hobbyist groups. Yet, little research has evaluated the long term use of currently available prostheses in daily life activities, beyond laboratory or survey studies. We seek to objectively measure how experienced unilateral upper limb prosthesis-users employ their prosthetic devices and unaffected limb for manipulation during everyday activities. In particular, our goal is to create a method for evaluating all types of amputee manipulation, including non-prehensile actions beyond conventional grasp functions, as well as to examine the relative use of both limbs in unilateral and bilateral cases. This study employs a head-mounted video camera to record participant’s hands and arms as they Figure 1: A video screenshot from the head-mounted camera (for complete unstructured domestic tasks within their own homes. participant P2).

As the closing zipper completes fusion of the urethral folds within the penile shaft to form a tubular urethra (~ 13 weeks), canali- zation of the urethral plate continues in proximal to distal fashion into the glans penis to directly form the urethra within the glans without forming an open urethral groove. Initially, the urethral plate is attached ventrally to the epidermis via an epithelial seam, which is remodeled and eliminated, thus establishing me- senchymal confluence ventral to the glanular urethra. The morphogenetic remodeling involves the strategic expression of cytokeratin 7, FoxA1 and uroplakin in endodermal epithelial cells as the tubular glanular urethra forms. -
Detailed and Applied Anatomy for Improved Rectal Cancer Treatment
REVIEW ARTICLE Annals of Gastroenterology (2019) 32, 1-10 Detailed and applied anatomy for improved rectal cancer treatment Τaxiarchis Κonstantinos Νikolouzakisa, Theodoros Mariolis-Sapsakosb, Chariklia Triantopoulouc, Eelco De Breed, Evaghelos Xynose, Emmanuel Chrysosf, John Tsiaoussisa Medical School of Heraklion, University of Crete; National and Kapodistrian University of Athens, Agioi Anargyroi General and Oncologic Hospital of Kifisia, Athens; Konstantopouleio General Hospital, Athens; Medical School of Crete University Hospital, Heraklion, Crete; Creta Interclinic, Heraklion, Crete; University Hospital of Heraklion, Crete, Greece Abstract Rectal anatomy is one of the most challenging concepts of visceral anatomy, even though currently there are more than 23,000 papers indexed in PubMed regarding this topic. Nonetheless, even though there is a plethora of information meant to assist clinicians to achieve a better practice, there is no universal understanding of its complexity. This in turn increases the morbidity rates due to iatrogenic causes, as mistakes that could be avoided are repeated. For this reason, this review attempts to gather current knowledge regarding the detailed anatomy of the rectum and to organize and present it in a manner that focuses on its clinical implications, not only for the colorectal surgeon, but most importantly for all colorectal cancer-related specialties.

Stretching and Positioning Regime for Upper Limb
Information for patients and visitors Stretching and Positioning Regime for Upper Limb Physiotherapy Department This leaflet has been designed to remind you of the exercises you Community & Therapy Services have been taught, the correct techniques and who to contact with any queries. For more information about our Trust and the services we provide please visit our website: www.nlg.nhs.uk Information for patients and visitors Muscle Tone Muscle tone is an unconscious low level contraction of your muscles while they are at rest. The purpose of this is to keep your muscles primed and ready to generate movement. Several neurological causes may change a person’s muscle tone to increase or decrease resulting in a lack of movement. Over time, a lack of movement can cause stiffness, pain, and spasticity. In severe cases this may also lead to contractures. Spasticity Spasticity can be defined as a tightening or stiffness of the muscle due to increased muscle tone. It can interfere with normal functioning. It can also greatly increase fatigue. However, exercise, properly done, is vital in managing spasticity. The following tips may prove helpful: • Avoid positions that make the spasticity worse • Daily stretching of muscles to their full length will help to manage the tightness of spasticity, and allow for optimal movement • Moving a tight muscle to a new position may result in an increase in spasticity. If this happens, allow a few minutes for the muscles to relax • When exercising, try to keep head straight • Sudden changes in spasticity may
