Social and societal pressures play an enormous role in the acceptance and use of prosthetic devices. Over the past 15 years, the United States has seen a radical shift in the mentality around prosthetic devices as amputees now choose function over form and encourage broader social acceptance of prostheses. This transition is not a global change, however, as(More)
Determination of net joint moments and powers requires accurate measurements of mass and centre of mass (COM) for the limb segments. The objective of this research was to develop regression equations for calculating mass and COM of the hoof segment that are applicable over a wide range of hoof morphologies. Ninety-one hooves (mean +/- s.d. 0.99 +/- 0.50 kg)(More)
BACKGROUND Energy storage and return feet are designed for active amputees. However, little is known about the socket reaction moments in transtibial prostheses with energy storage and return feet. The aim of this study was to investigate the effect of alignment changes on the socket reaction moments during gait while using the energy storage and return(More)
The alignment of a lower limb prosthesis affects the way load is transferred to the residual limb through the socket, and this load is critically important for the comfort and function of the prosthesis. Both magnitude and duration of the moment are important factors that may affect the residual limb health. Moment impulse is a well-accepted measurement(More)
Pulmonary aspiration of regurgitated feeding material is a recognized complication of enteral nutrition by feeding tube. Nasopulmonary intubation with feeding tubes has been reported infrequently. We present two patients with such complications. In one, nasopulmonary intubation resulted in a pneumothorax. In the other unrecognized misplacement resulted in(More)
Rapid advances in science and technology are opening doors for the fulfillment of human desires in ways that were not previously possible. Neural, genetic, pharmacological, and physical forms of augmentation of the human experience promise to multiply both in number and complexity over the next decades. It is our responsibility to create a public, open(More)
A person with amputation's subjective perception is the only tool available to describe fit and comfort to a prosthetist. However, few studies have investigated the effect of alignment on this perception. The aim of this article is to determine whether people with amputation could perceive the alignment perturbations of their prostheses and effectively(More)
Alignment - the process and measured orientation of the prosthetic socket relative to the foot - is important for proper function of a transtibial prosthesis. Prosthetic alignment is performed by prosthetists using visual gait observation and amputees' feedback. The aim of this study was to investigate the effect of transtibial prosthesis malalignment on(More)
