Historians of orthopaedics, artificial limbs and disability have devoted a great deal of attention to children and soldiers but have neglected to give sufficient space in their studies to industrial workers, the other patient group that has been identified as crucial to the development of these areas. Furthermore, this attention has led to an imbalanced focus on charitable and philanthropic act...
In the present study, we modeled a reaching task as a two-link mechanism. The upper arm and forearm motion trajectories during vertical arm movements were estimated from the measured angular accelerations with dual-axis accelerometers. A data set of reaching synergies from able-bodied individuals was used to train a radial basis function artificial neural network with upper arm/forearm tangenti...
OBJECTIVES The principle underlying this project is that, despite nervous reorganization following upper limb amputation, original pathways and CNS relays partially maintain their function and can be exploited for interfacing prostheses. Aim of this study is to evaluate a novel peripheral intraneural multielectrode for multi-movement prosthesis control and for sensory feed-back, while assessing...
Introduction Lower-extremity amputees, the group with which this paper is concerned, include persons who have been subjected to gross anatomic loss of the lower limbs at widely varying levels, such as partial foot amputation, below-knee and above-knee amputations, knee or hip disarticulation, and hemipelvectomy. Amputation at each level is attended by distinctive problems of functional loss, fi...
Introduction Conventional below-knee prostheses are manufactured of rigid materials for durability and stability. The use of glass fibre and resin composite materials to form the rigid shank of the below-knee prosthesis is well established in many countries and forms part of the modern practice of cosmetic prosthesis manufacture. While these materials are strong, durable , easily worked and cos...
much felt in Calcutta, and I therefore trust that the distinguished professors of our Metropolitan College will pardon me for venturing publicly to write on a subject with which some experience, as a surgeon in the mofussil, has made mo paiul'ully familiar. If we take the annual returns of the operations performed at the different dispensaries in the North-Western Provinces, for example, we sha...
17cc-2-1-009 Introduction Inhaled nitric oxide (NO) is a selective pulmonary vasodilator which reduces pulmonary artery pressure and increases arterial oxygenation in patients with adult respiratory distress syndrome (ARDS). Despite these beneficial effects, inhaled NO has not yet been shown to improve outcome. During artificial ventilation, it can be administered in the downstream of the venti...
We report a case of 30 year old alcoholic male admitted with vomiting, drowsiness, limb weakness and fasciculations after alleged history of consumption of 30 ml of chlorpyriphos insecticide. He had low serum cholinesterase levels. With standard treatment for organophosphorus poisoning (OPP), he improved gradually until day 5, when he developed neck and limb weakness and respiratory distress. T...
PURPOSE To evaluate the lower limb proprioceptive sensation in patients with femoral amputation who received an artificial joint. MATERIALS AND METHODS 22 patients (18 men, 4 women), 24-65 years old (mean: 42), who had undergone above-the-knee joint amputation and underwent evaluation of proprioception using joint reposition in a predetermined angle of 15° knee flexion. The measurements were ...
To enable intuitive operation of powered artificial legs, an interface between user and prosthesis that can recognize the user's movement intent is desired. A novel neural-machine interface (NMI) based on neuromuscular-mechanical fusion developed in our previous study has demonstrated a great potential to accurately identify the intended movement of transfemoral amputees. However, this interfac...
