To understand the step characteristics during sprinting in lower-extremity amputees using running-specific prosthesis, each athlete should be investigated individually. Theoretically, sprint performance in a 100-m sprint is determined by both step frequency and step length. The aim of the present study was to investigate how step frequency and step length correlate with sprinting performance in elite unilateral transtibial amputees. By using publicly-available Internet broadcasts, the authors analyzed 88 races from 7 unilateral transtibial amputees. For each sprinters run, the average step frequency and step length were calculated using the number of steps and official race time. Based on Pearsons correlation coefficients between step frequency, step length, and official race time for each individual, the authors classified each individual into 3 groups: step-frequency reliant, step-length reliant, and hybrid. It was found that 2, 2, and 3 sprinters were classified into step-frequency reliant, ...
The distribution of interface stresses between the residual limb and prosthetic socket of a transtibial amputee has been considered as a direct indicator of the socket quality fit and comfort. Therefore, researchers have been very interested in quantifying these interface stresses in order to evaluate the extent of any potential damage caused by the socket to the residual limb tissues. During the past 50 years a variety of measurement techniques have been employed in an effort to identify sites of excessive stresses which may lead to skin breakdown, compare stress distributions in various socket designs, and evaluate interface cushioning and suspension systems, among others. The outcomes of such measurement techniques have contributed to improving the design and fitting of transtibial sockets. This article aims to review the operating principles, advantages, and disadvantages of conventional and emerging techniques used for interface stress measurements inside transtibial sockets. It also reviews and

Investigators will use a novel combination of functional magnetic resonance imaging (fMRI) and transcranial magnetic stimulation (TMS) to study how the functional connections between brain regions change in amputees who have lost a lower leg. These studies may lead to new rehabilitation strategies that target altered brain connections to improve functional outcomes in lower-limb amputees. Nearly two million people in this country have suffered major or minor limb loss. In major limb loss cases, 90 percent involve leg amputation below the knee. Research shows that after a leg is amputated structural and functional changes occur in the part of the brain that previously supported the legs motor and sensory functions. Scientists do not yet know how connections between brain regions might change following limb loss, and how disruptions in the communication patterns between brain areas might relate to clinical outcomes. The investigators will test two main hypotheses: 1) The connections between brain ...
The ability to run, jump, and play games is important for the general wellbeing of limb-deficient youngsters. In the past, prosthetic foot designs such as the SACH (Solid Ankle Cushioned Heel) were designed principally for walking and did not fulfill the special mobility and functional demands of children. With the advent of space-age materials that are light, strong and durable a new generation of prosthetic feet has evolved. The Flex-Foot" is one of those state-of-the-art prothestic feet that proportedly has a potential for energy storage to enhance propulsion of the artificial limb during gait. The hypothesis of the enhanced energy-return has yet to be investigated systematically.. The purpose of this project was to quantify the gait mechanics of unilateral below-knee BK) amputee children while they wore either the Flex-Foot" or the SACH foot during slow and fast walking. Ten BK child amputees were fit with a new SACH foot prosthesis, allowed to ambulate freely for two months, and their gait ...
This study will examine whether tactile (touch) abilities at the lip are more acute in people with upper limb amputation compared with healthy normal volunteers. People with an amputated upper limb have an expanded brain representation of the lip that may correlate with heightened tactile spatial acuity.. Normal volunteers will be recruited for this study. Candidates will be screened with physical and neurological examinations. (Amputee volunteers will be studied at the amputee clinic at the University of Tubingen, Germany.). Participants will sit comfortably in a chair, wearing a blindfold, during the following experiments:. ...
Osteoarthritis is the most common form of arthritis. It causes pain, swelling and reduced motion in the joints as the result of a breakdown of the cartilage in the joints. Cartilage is the slippery, shock-absorbing padding that covers the end of the bones in the joint. About 20 percent of the general population has osteoarthritis of the knee or hip due to age, excess weight or joint injuries. Research indicates that 40 percent of people with a single below-knee amputation have osteoarthritis in the sound (intact) knee. Even worse, 60 to 75 percent of people with an above-knee amputation have osteoarthritis in the sound knee. A recent study reported that 80 percent of people who have used a prosthesis for more than 45 years will have knee pain. Osteoarthritis in the sound side hip occurred in about 45 percent of below-knee amputees and 73 percent of above-knee amputees within an average of 47 years after the amputation. An average of 18 percent of all amputees had osteoarthritis in the amputated ...

The good news is with our help, you will conquer your Phobia Of Amputees, without drugs.. ...
Leg amputations can overweight people get a prosthetic limb - Is a diabetic double amputee overweight a good candidate for prosthetic limbs? Depends. The level of amputation is most important as the higher the amputation the more difficult it is to walk with the prosthesis. Diabetes by itself is not a problem if controlled. Foot care is crucial to prevent amputation of the other leg. Weight might limit the options an amputee has as prosthetic components have weight limits. Inability to tolerate exercise is another limiting factor.
BACKGROUND: Key factors limiting patients with lower extremity amputations to achieve maximal functional capabilities are falls and fear of falling. A task-specific fall prevention training program has successfully reduced prospectively recorded trip-related falls that occur in the community by the elderly. However, this program has not been tested in amputees. QUESTIONS/PURPOSES: In a cohort of unilateral transtibial amputees, we aimed to assess effectiveness of a falls prevention training program by (1) quantifying improvements in trunk control; (2) measuring responses to a standardized perturbation; and (3) demonstrating retention at 3 and 6 months after training. Second, we collected patient-reported outcomes for balance confidence and falls control. METHODS: Fourteen male military service members (26 +/- 3 years) with unilateral transtibial amputations and who had been walking without an assistive device for a median of 10 months (range, 2-106 months) were recruited to participate in this ...
DESCRIPTION (provided by applicant): A new generation of dexterous prosthetic hands is becoming available, which are capable of a greater number of functions than conventional prostheses. To enable this increased functionality, we have pioneered a novel control platform which includes a surface electromyography (EMG) pattern recognition algorithm called MyoSense and a first-of-its-kind multi-channel conformal electrode interface called MyoLiner. The combination of these two technologies has allowed us, forthe first time, to give amputees the ability to point their index finger and operate their thumb independently in addition to the conventional hand open and close functionality. This technology has the potential to shift the paradigm in prosthetic controlfor the first time in over 50 years. In order to maximize the impact and accuracy of the technology, rehabilitation therapy is required, ideally within a 30-day golden window following amputation. However, the realities of patient fitting and ...

CONCLUSIONS: In nondemanding walking conditions with experienced amputees, participants reported that the more costly C-leg required less cognitive attention than the noncomputerized knee. However, this subjective experience did not translate to improved performance on neuropsychologic screening instruments or on walking speed. Noncomputerized prostheses may be adequate for a majority of amputees, and further research is needed to identify particular groups of amputees (ie, new amputees, amputees with complex physical or cognitive demands) who may benefit from computerized prostheses.. ...

Amputees with prosthetic limbs may soon have much a better sense of touch, temperature and texture, thanks to the power of the sun.
Yes, things can happen that will require repair or replacement, so its a good idea to know about warranties and what to expect from your prosthetist. Get small problems with your prosthesis taken care of promptly. There is no benefit to waiting until your prosthesis falls apart or causes serious skin breakdown. If you wear a prosthesis too long when it needs repair or replacement, you can do harm, not only to your residual limb, but also to other parts of your body. Strain on other muscles, especially in your back, shoulders and hips will affect posture in addition to performance of the device and the energy needed to use it. Early prevention is much better than long term treatment.. Who can I contact for more information ...
Background Recent conflicts have seen an increase in trauma related military amputees who incur complex injuries which result in varied residual limbs. In many cases these amputees have been provided with state of the art (SOTA) components with the expectation that they will transfer into NHS care after military discharge. However, there is a lack of knowledge around how prosthetic prescriptions are made in both the MOD and NHS, including patient involvement. It is important to explore prosthetic prescription decisions to enhance the quality, consistency and equity of care delivery for trauma amputees. This thesis explores decision making in prosthetic care for trauma amputees in the UK during this period of change. Aims To explore aspects of prosthetic care provision in the UK including clinical decision making, patient experience and the transition of prosthetic care from the MOD to the NHS. Design An exploratory qualitative project informed by decision making and patient involvement theory. ...
Forty amputee patients will be evaluated for satisfaction with the prosthesis, pressure repartition pattern and functional capabilities.. Pressure at the stump-socket interface will be recorded using a set of 14 single cells sensors placed in predefined positions onto the stump. Pattern of pressure will be measured in four tasks: sitting posture, standing posture, gait initiation, and gait at preferred velocity.. Reproducibility of the pressure repartition pattern will be analyzed by repeating gait and standing posture task in the first 15 patients included.. In patients whom prosthesis has been modified on the basis on the first pressure measurement (pressure peak and bad functional capacities), a new pressure measurement will be repeated 2-8 weeks apart.. Postural and gait abilities will be also assessed in 40 age/gender matched non-amputated subjects to serve as control data. ...
Methods: At admission to the rehabilitation centre objective and subjective parameters were assessed including demographic data and levels of daily activity using standardized questionnaires. Three months after prosthetic fitting a follow-up was performed and additional parameters such as walking speed, step length and vertical ground reaction forces were examined using a dynamic gait analysis ...
To speed development of a mobile system providing a sense of touch that amputees can use anywhere, Case Western Reserve University researchers and colleagues at the Louis Stokes Cleveland Veterans Affairs Medical Center have assembled a team including medical device-makers Medtronic and Ardiem Medical, Lawrence Livermore National Laboratory, the universities of Chicago and California at San Francisco, and the Providence VAs Ocean State Research Institute.
In a previous study, Sorensens implants were connected to a sensory-enhanced prosthetic hand that allowed him to recognize shape and softness. In this new publication about texture in the journal eLife, the bionic fingertip attains a superior level of touch resolution.. Simulating touch in non-amputees. This same experiment testing coarseness was performed on non-amputees, without the need of surgery. The tactile information was delivered through fine needles that were temporarily attached to the arms median nerve through the skin. The non-amputees were able to distinguish roughness in textures 77% of the time.. But does this information about touch from the bionic fingertip really resemble the feeling of touch from a real finger? The scientists tested this by comparing brain-wave activity of the non-amputees, once with the artificial fingertip and then with their own finger. The brain scans collected by an EEG cap on the subjects head revealed that activated regions in the brain were ...
Amputees at Spalding Rehabilitation Hospital in Denver, Colorado receive personalized treatment throughout their amputation rehab and recovery.
The feeling we have of our own body, sometimes called "body image," is fundamental to self-awareness. However, by altering sensory input, the body image can be modified into impossible configurations. Can impossible movements of the body image be conjured solely via internally generated mechanisms, and, if so, do the structural characteristics of the body image modify to accommodate the new movements? We encouraged seven amputees with a vivid phantom arm to learn to perform a phantom wrist movement that defied normal anatomical constraints. Four reported success. Learning the impossible movement coincided in time with a profound change in the body image of the arm, including a sense of ownership and agency over a modified wrist joint. Remarkably, some previous movements and functional tasks involving the phantom arm became more difficult once the shift in body image had occurred. Crucially, these introspective reports were corroborated by robust empirical data from motor imagery tasks, about ...
Decreased burden on the health care system and a higher quality of life for patients likely offset higher initial costs of amputation and prosthetic intervention.

Dewayne Smock doesnt have a leg to stand on.. Smock says this in jest, but its also the literal truth. A surgeon amputated both his legs last summer after infection invaded them - a complication of diabetes.. The 53-year-old lives in a beat-up Mazda van that he is unable to drive. Because of mobility issues, the amputee says he spends most of his day sitting in the front passenger seat of the oxidized silver van, sleeping when he can, playing games on his phone when it has juice. Sometimes he just sits smoking a Pall Mall, counting up his regrets in his offbeat, tongue-in-cheek sort of way.. His friend David Gately lives with Smock and serves as chauffeur, health aide and the son Smock never had. Gately parks here and there, hoping not to draw attention from property owners or police. Until recently, Gately often drove him to Roy Raley Park for a change of view and a chance for Smock to recharge his wheelchair using an electrical outlet at the pavilion. He chatted with the teens hanging out at ...

After every few dashes across Court 14, Kelly Bruno reached down to her right leg and flicked at something. It was a gesture so slight and so fleeting, she could have been swatting away a bug. It was also the only thing she did that was not in the protocol for a United States Open ball girl - nowhere does it mention popping the pressure valve on a prosthetic leg.. Bruno was born with several defects in her right leg and has been an amputee since she was 6 months old. By 18, she had turned herself into a track star among disabled athletes, with her own sponsorship deals. And as a world-class triathlete and Ironman competitor, she has raced in some of the most grueling events on the planet. Now, at 24, Bruno has scaled back her training for three weeks to shuttle back and forth across courts at the Billie Jean King National Tennis Center to scoop up balls at the net. In a job done correctly only by those who are barely noticed, Bruno has stood out by blending in.. "Its definitely harder than I ...

available for free.. The feature article is a randomized controlled study evaluating balance in patients with unilateral transtibial amputations secondary to peripheral artery disease (PVD). The authors used a stabilometer to collect data on center of pressure and load distribution in 10 skilled prosthetics users (SPU) and 18 first-fitted amputees (FFA) to assess single- and double-limb support. In static double-limb support, the FFA group had a 69.7 percent greater radius of the circle than the SPU group. The radius of the circle in single- and double-limb support was almost identical (1.6 percent difference) within the FFA group, whereas the SPU group showed significant difference between double-limb support and single-limb (non-affected leg) support. The load distribution was significantly larger in the FFA versus the SPU group. The findings may indicate that patients with amputations secondary to PVD develop a balance and weight distribution strategy prior to surgery, which allows for ...
Using beams of light to allow amputees not only to control but also to feel the movement of prosthetic limbs is the ambitious goal of a new $5.6 million Department of Defense initiative.
The purpose of the study was to determine the feasibility of quantifying pressure-related socket discomfort by using psychophysical methods. The first experiment involved the application of known uniform pressure to the residual limbs of three transtibial amputees. Category ratio scales were used to measure sensations of pressure, pain, and perceived discomfort. The second experiment involved altering the geometry at the fibula head and distal tibia of the subjects fitted PTB sockets with wafers of varying thickness and use of the same three scales to measure response to the variations in local point-specific pressures. Two of the subjects had more than 32 years of experience with PTB sockets, whereas the third subject had just been fitted with a temporary prosthesis. Results indicated that response functions for global uniform pressure varied among the subjects but were similar for the modifications at specific locations. Both experienced amputees reported constant pressure sensations between 10 and
I lost my leg in late 2005. And after the initial weeks of healing and recovery, I quickly got a socket that worked well for me. I wore the prosthesis all day long, mastered my day to day life by myself and mostly by walking and public transport and after a bit more than three months I was back on my job, full time, with long travels to Asian and African countries. I was active, I was fine, I was happy and content. But for the last 5 years I have had more and more problems with my residual limb. The volume changes throughout the day, throughout the week, throughout the month. A socket I find almost impossible to get into in the morning almost falls off in the afternoon. A socket that gives me great foot placement even off the beaten track and allows precise footwork on mountain paths on one day, hardly gets me around the house the next day. As I love to be active and independent, the issue of finding a well-fitting socket has been on my mind for a long time. I changed from a pure vacuum system ...
