Amputation is a serious life-changing event in a human being's life, bringing about one of the most prominent, sudden, and, in most cases, unexpected turning points in his or her life. Amputation has an impact on several aspects of an individual's activities, including activities of daily living, employment, social life, personal relationships and recreation…

Download file to see previous pages The 19th century saw the use of more advanced lighter-weight prostheses made of wood. It has been found that amputations are largely due to trauma in developing countries while they are from vascular reasons in the developed countries.2 Vascular problems are usually associated with a lot of other illnesses which may limit a person's mobility and hence eliminate the urgent need for an advanced prosthesis. On the contrary, post-trauma amputees are usually younger with more active lifestyles and hence are candidates for advanced prosthetic placements so as to ensure uncompromised quality of life.
Conventional mechanically controlled prostheses utilize a pneumatic or hydraulic damper to provide the appropriate gait parameters for the user at his or her conventional normal walking speed.3 The adjustment is usually effected by a prosthetist. When there is a change in walking speed, the pendulum action of the prosthesis for the change in stride or step is compensated by tilting the pelvis or such other physical maneuvers which delay the extension so that the foot is appropriately placed for the next step. These physical negotiations not only mar the flow of the gait but also use up more energy.

The basic concept of the microprocessor-controlled lower limb prosthesis is the use of a microprocessor-controlled damper with the help of which step time is measured and knee extension is adjusted to changing walking speeds. The first computer-controlled prosthesis was devised by Blatchford in the early 1990s with a view to improving the amputees' symmetry of gait over a wide a range of walking speeds. The "Intelligent Prosthesis (IP)," as it was called, programs the knee to optimum swing settings for each individual user to achieve the smoothest gait pattern with less energy expense.5 A pneumatic control unit in the knee senses speed changes and adjusts the swinging speed of the prosthesis, making the gait not only look natural but also feel natural for the user. However, the IP works well only on even surfaces. In 1998, Blatchford introduced the more advanced Adaptive Prosthesis. The Adaptive Prosthesis has a microcomputer that adjusts to the change in terrain underfoot and its combination of hydraulics and pneumatics assisted weightbearing and responded to changes in the walking speed. The Adaptive Prosthesis provides the required degree of stability for walking, standing and climbing as needed by each individual user. The IP+ of Blatchford offers individually programmed microprocessor cadence control, stance stability to provide a natural gait, and a Stanceflex unit that helps reduce shock during heel strike. The Smart IP of Blatchford, in addition to all of the above features, can be re-programmed at any time by the user for footwear and activity level changes. The Smart IP claims through its studies and trials that with its intelligent pneumatic swing ...Download file to see next pagesRead More

Advancements in Prosthetic Technology

...B.C. when Egyptians utilized fiber to fashion prosthetic limbs. Throughout history, adaptations to prosthetics occurred as a result of industrial advancements and scientific research. Archaeologists have discovered bronze pegs used to simulate lost limbs (Levy, 2012). During the Dark Ages, individuals used wooden peg legs with fashioned wood, metal and leather crutches for support (Levy). By the 1500s, iron was used to simulate limbs with a new ability to use metallurgy to fashion joints to allow for more flexible movement. By the 1900s, rubber technology, robotics, and microprocessor technologies contributed to a...

Depression and Amputees

.... In contrast, Mozumdar et al. (2010) investigated whether depression among persons with lower extremity amputation (LEA) is really higher than the general population. The investigators found that “the depression levels of the LEA also were not associated to most of the physical health factor” (Mozumdar et al., 2010, p. 887). The Mozumdar et al. (2010) conclusion was based on a sample of 85 amputees out of an original target of 1,000 amputees. A low sample was realized because only a few agreed to give their informed consent. Using a sample of 56 Jordanian patients with “unilateral lower limb amputation” with mean duration of 8.4+/-5.75 years, Hawamdeh et al. (2008) assessed the...

Acute Knee Sprain Assessment

...with abnormal findings. Upon physical examination, the patient does not show any external signs of a fracture, however, MRI scan reveals a minor depression. The patient has also suffered a blow to the spinal cord which resulted in a slight forward displacement of L5 over S1. The forward displacement is minor, therefore, does not require complementary surgery or altered treatment regime. During physical examination, the Lachman test was positive which indicated a tear of the anterior cruciate ligament. The prescribed treatment falls into the category of “conservative management” and involves physical therapy and using a knee brace to support the joint. Once recovered, the patient is advised to engage in...

Prosthetic Dentistry

...prosthetics is the development of surface material that is bactericidal and least supportive of growth of any type of bacteria, particularly, that of super bug, MRSA 15 and 16. Our experiments to identify such an ideal surface lead to identification of molliplast as a denture surface that is least supportive of the growth of MRSA 16 compared to acrylic and visco-gel. Further experiments to identify the effectiveness of denture cleansers, like Milton and Perform, on the growth of MRSA 16, shows that both these agents are effective in killing the MRSA 16. Between the two denture cleansing agents studied, Perform was found to be more effective on both the denture surface materials, viz., acrylic and visco-gel,...

Microprocessor of arbitrary size, that can be used to contain procedures and data structures. Segmentation has several advantages over more conventional linear memory architectures. It supports structured software, since segments can contain meaningful program units and data, and more compact code, since references within a segment can be shorter (and locality of reference usually insures that the next few references will be within the same segment). Segmentation also lends itself to efficient implementation of sophisticated memory management, virtual memory, and memory protection. References: 1.
