To help people with impairment of lower extremity movement regain the ability to stand and walk, enhance limb function, this study proposes an anthropomorphic design electrically driven, lower-limb exoskeleton rehabilitation robot. The angular range robot’s motion was determined according characteristics targeted joints; robot given active–passive 12 degrees freedom. multi-degree-of-freedom hip...

When we look at our hands we are immediately aware that they belong to us and we rarely doubt about the integrity, continuity and sense of ownership of our bodies. Here we explored whether the mere manipulation of the visual appearance of a virtual limb could influence the subjective feeling of ownership and the physiological responses (Skin Conductance Responses, SCRs) associated to a threaten...

Early thrombosis of artificial microvascular grafts (AMG, grafts < or = 2 mm internal diameter) prevents their reliable clinical use. The present studies were undertaken to examine the effect of hirudin, a thrombin-specific inhibitor, and of the F(ab')2 fragment of PG-1, a monoclonal antibody (MoAb) directed against guinea pig platelet membrane glycoprotein Ib (GPIb), on AMG patency in an anima...

Incorrect electrode cable connections during electrocardiographic (ECG) recording can simulate rhythm or conduction disturbance, myocardial ischaemia and infarction, as well as other clinically important abnormalities. When only precordial or only limb cables, excluding the neutral cable, have been interchanged the waveforms in the different leads are re-arranged, inverted, or unchanged, wherea...

The concept of mechanical impedance represents the interactive relationship between deformation kinematics and the resulting dynamics in human joints or limbs. A major component of impedance, stiffness, is defined as the ratio between the force change to the displacement change and is strongly related to muscle activation. The set of impedance components, including effective mass, inertia, damp...

Developing supernumerary limbs is a rare congenital condition that only a few cases have been documented. Depending on the cause and developmental conditions, they may be single, multiple or complicated, and occur as a syndrome or associated with other anomalies. Polymelia is defined as the presence of extra limb(s) which have been reported in human, mouse, chicken, calf and lamb. It seems that...

Amputees cannot feel what they touch with their artificial hands, which severely limits usefulness of those hands. We have developed a technique that transfers remaining arm nerves to residual chest muscles after an amputation. This technique allows some sensory nerves from the amputated limb to reinnervate overlying chest skin. When this reinnervated skin is touched, the amputees perceive that...

Peripheral artery disease (PAD) occurs when plaque accumulates in the arterial system and obstructs blood flow. Narrowing of the abdominal aorta and the common iliac arteries due to atherosclerotic plaques restricts blood supply to the lower limbs. Clinically, the lower limb symptoms of PAD are intermittent claudication, discoloration of the toes, and skin ulcers, all due to arterial insufficie...

A trauma or congenital pathology may seriously compromise the performance of upper limbs from an operative standpoint and informally, tluough sensitivity. These special aspects show how difficult it is to develop an artificial limb capable to reply important functions, such as for example: eating, independence in the batluoom and so on In order to carry out a good treatment with orthopaedic dev...
