Osseointegrated, percutaneous implants as the force bearer for exoprosthetics after limb amputation have been used in individual cases for clinical rehabilitation of amputees during the past years. Most experience in this field in Germany has been accumulated at the Sana Klinik in Lübeck with the so-called endo-exo prosthesis (EEP) system. The two-step implantation procedure can now be considered as reliable. Following a well-documented learning curve initial soft tissue problems concerning the cutaneous stoma can now be regarded as exceptions...

INTRODUCTION: Transcutaneous, bone anchored prostheses have proved to be an alternative for amputees. In addition to the safe osseointegration of the implant, the correct prosthetic alignment is also important. Therefore, the interaction between prosthesis components and the prosthesis wearer is significant and the role of the certified prosthetist should not be underestimated. AIM: The aim of treatment is the best possible compensation of disability after limb loss with increase of physical abilities and comfort of the prosthesis wearer by means of bone anchored prosthesis...

The functional capabilities of individuals with upper limb disabilities are assessed throughout rehabilitation and treatment regimens using functional outcome measures. For the upper limb amputee population, there are none which quantitatively take into account the quality of movement while an individual is performing tasks. In this work, we demonstrate the use of an integrated movement analysis framework, based on motion capture and ground reaction force data, to capture quantitative information about how subjects complete a commonly used functional outcome measure, the Box and Blocks Test (BBT)...

BACKGROUND: Mental practice (MP) through motor imagery is a cognitive training strategy used to improve locomotor skills during rehabilitation programs. Recent works have used MP tasks to investigate the neurophysiology of human gait; however, its effect on functional performance has not been evaluated. In the present study, the influence of gait-oriented MP tasks on the rehabilitation process of gait in transtibial amputees was investigated by assessing the vertical (V), anterior-posterior (AP), and medio-lateral (ML) ground reaction forces (GRFs) and the time duration of the support phase of the prosthetic limb...

PURPOSE: Aim of this pilot study was to assess safety and functioning of a microprocessor-controlled knee prosthesis (MPK) after a short familiarization time and no structured physical therapy. MATERIALS AND METHODS: Five elderly, low-active transfemoral amputees who were fitted with a standard non-microprocessor controlled knee prosthesis (NMPK) performed a baseline measurement consisting of a 3 D gait analysis, functional tests and questionnaires. The first follow-up consisted of the same test procedure and was performed with the MPK after 4 to 6 weeks of familiarization...

INTRODUCTION: Lower limb amputations have detrimental influences on the quality of life, function and body image of the affected patients. Following amputation, prolonged rehabilitation is required for patients to be fitted with traditional socket prostheses, and many patients experience symptomatic socket-residuum interface problems which lead to reduced prosthetic use and quality of life. Osseointegration has recently emerged as a novel approach for the reconstruction of amputated limbs, which overcomes many of the socket-related problems by directly attaching the prosthesis to the skeletal residuum...

In developed countries, the highest number of amputees are elderly with transtibial amputation. Walking on inclined surfaces is difficult for amputees due to loss of muscle volume and strength thereby transtibial amputees (TA) rely on the intact limb to maintain stability. The aim of this study was to use the concatenated non-negative matrix factorization (CNMF) technique to calculate muscle synergy components and compare the difference in muscle synergies and their associated activation profiles in the healthy and amputee groups during ramp ascending (RA) activity...

BACKGROUND: To overcome the challenges of rehabilitation of bilateral transfemoral amputees, we developed a novel "hip prosthesis in the sitting posture." Case Description and Methods: A 64-year-old male bilateral transfemoral amputee was transferred for rehabilitation 4 months following a burn injury. His wounds remained unhealed for 20 months; thus, he was unable to participate in standing training with the standard prosthetic sockets. Hip prosthesis in the sitting posture has very little friction between the sockets and residual limbs, which facilitated our patient to begin standing and walking exercises...

Lower-limb amputees typically require some form of prosthetic limb to ride a bicycle for recreation or when competing. At elite-level racing speeds, aerodynamic drag can represent the majority of the resistance acting against a cyclists' forward motion. As a result, the reduction of such resistance is beneficial to an amputee whereby the form and function of the prosthetic limb can be optimized through engineering. To measure the performance of such limbs, field testing provides a cost-effective and context-specific method of aerodynamic drag measurement...

BACKGROUND: Bone anchorage of an artificial limb has been proven to be an alternative intervention for amputees when prosthesis use is seriously reduced because of stump problems. Little is known about how prosthesis components interact with bone and joints and which potential the optimum use provides with respect to quality of treatment of leg amputees. OBJECTIVE: Does osseointegration influence the motor activity of residual limbs differently compared with socket prostheses? How should prosthesis components be aligned? What type of prosthetic knee joints should be preferred in transfemoral amputees? MATERIAL AND METHODS: Transfer of biomechanical knowledge of socket prosthetics to bone-anchored prostheses...

Amputation is an unfortunate outcome of a variety of orthopedic conditions. Many amputees can be functionally fitted with conventional suspension sockets. A substantial subset, however, fails this conventional treatment and is unable to function. In Europe, an alternative to socket-based prostheses has been available for 25 years. Patients there who are unable to functionally use socket-based prostheses have been offered the possibility for transcutaneous osseointegration. With this technology, the prosthetic limb can be rigidly attached to the residual bone, and the socket is eliminated, in many cases enabling improved function and patient satisfaction...

Research in myoelectric pattern recognition (MPR) for the prediction of motor volition has primarily focused on the upper limbs. Recent studies in the lower limbs have mainly concentrated on prosthetic control, while MPR for lower limb rehabilitation purposes has received little attention. In this work we investigated the viability of a MPR system for the prediction of four degrees of freedom controlled in a near natural or physiologically appropriate fashion. We explored three different electrode configurations for acquiring electromyographic (EMG) signals: two targeted (bipolar and monopolar) and one untargeted (electrodes equally spaced axially)...

The direct attachment of osseointegrated (OI) prostheses to the skeleton avoids the inherent problems of socket suspension. It also provides physiological weight bearing, improved range of motion in the proximal joint, as well as osseoperceptive sensory feedback, enabling better control of the artificial limbs by amputees. The present article briefly reviews the pioneering efforts on extremity osseointegration surgeries in Sweden and the development of the OPRA (Osseointegrated Prostheses for the Rehabilitation of Amputees) program...

INTRODUCTION: Early ambulation is the principal objective in trans-femoral amputees. Postamputation modifications complicate the rehabilitation process due to a reduced control at the interface between stump and prosthesis. The aim of this study is to determine whether magnetic resonance imaging depicts the amount of fatty degeneration of the thigh muscles after trans-femoral amputation (TFA). METHODS: A total of 12 patients following a TFA on the basis of a bone neoplasm or metastasis with an evaluable postoperative MRI were identified...

BACKGROUND: Chronic low back pain (LBP) is a common musculoskeletal impairment in people with lower limb amputation. Given the multifactorial nature of LBP, exploring the factors influencing the presence and intensity of LBP is warranted. OBJECTIVE: To investigate which physical, personal, and amputee-specific factors predicted the presence and intensity of LBP in persons with nondysvascular transfemoral amputation (TFA) and transtibial amputation (TTA). DESIGN: A retrospective cross-sectional survey...

BACKGROUND: A high number of upper extremity myoelectric prosthesis users abandon their devices due to difficulties in prosthesis control and lack of motivation to train in absence of a physiotherapist. Virtual training systems, in the form of video games, provide patients with an entertaining and intuitive method for improved muscle coordination and improved overall control. Complementary to established rehabilitation protocols, it is highly beneficial for this virtual training process to start even before receiving the final prosthesis, and to be continued at home for as long as needed...

INTRODUCTION: Femoral neck fracture on amputated limb is an uncommon lesion and challenging to manage. CASE REPORT: We report a case of a displaced neck fracture of the left femur in a 57-year-old female. She underwent at the age of the three a below-knee amputation of the ipsilateral limb for post traumatic ischemia. The fracture was managed by a total hip arthroplasty (THA), as a primary procedure. In this article we describe our experience of this unusual entity...
