The fundamental thumb-tip force vectors produced by the muscles of the thumb.
A rigorous description of the magnitude and direction of the 3D force vector each thumb muscle produces at the thumb-tip is necessary to understand the biomechanical consequences to pinch of a variety of paralyses and surgical procedures (such as tendon transfers). In this study, we characterized the 3D force vector each muscle produces at the thumb-tip, and investigated if these thumb-tip forc...
متن کاملThing: A Robotic Hand with Realistic Thumb Pronation
Thing is a robotic hand with three digits, a pronating opposable thumb, and a 2 D.O.F. wrist. Designed to more accurately model human hand positioning and grasping capabilities than previous models, Thing is controlled by a flex-sensor-equipped glove which relays the user’s finger positions by means of flex sensors. It will also, by time of publication, incorporate an image-processing system fo...
متن کاملSushi hand roll dressing for thumb polydactyly
Surgery for thumb polydactyly is a commonly performed orthopaedic procedure in Asia Pacific region. Despite extensive publications on topical dressing methods and dressing materials in paediatric wounds, there is no single design that affords a secure and yet comfortable post-operative wound dressing for thumb polydactyly. We have devised a new dressing method, which can easily be fabricated fo...
متن کاملAutonomous motion planning of a hand-arm robotic system based on captured human-like hand postures
The paper deals with the problem of motion planning of anthropomorphic mechanical hands avoiding collisions and trying to mimic real human hand postures. The approach uses the concept of “principal motion directions” to reduce the dimension of the search space in order to obtain results with a compromise between motion optimality and planning complexity (time). Basically, the work includes the ...
متن کاملThumb polydactyly with a floating ulnar thumb.
Thumb polydactyly is reported to be the most common congenital anomaly of the hand in Japan. The floating type is not particularly rare, accounting for 0.9 to 15% of all cases of thumb polydactyly. However, to the best of our knowledge, there has been only one case of thumb polydactyly with a floating ulnar thumb, reported by Onizuka. Herein, we report a case very similar to that reported by On...
