Collecting large datasets of amputee gait data is notoriously difficult. Additionally, collecting data on less prevalent amputations or on gait activities other than level walking and running on hard surfaces is rarely attempted. However, with the wealth of user-generated content on the Internet, the scope for collecting amputee gait data from alternative sources other than traditional gait labs is intriguing. Here we investigate the potential of YouTube videos to provide gait data on amputee walking. We use an example dataset of trans-femoral amputees level walking at self-selected speeds to collect temporal gait parameters and calculate gait asymmetry...

Amputation is a traumatic incident that entails a chain of psychological, physical, and social events. The objectives of the study are to describe the beliefs and the philosophies of life related to the experience of suffering of traumatic amputees, analyze the importance of biomedical care, and describe other forms of care used.

The breach of the skin barrier is a critical issue associated with the treatment of individuals with transfemoral amputation (TFA) using osseointegrated, percutaneous titanium implants. Thirty TFA patients scheduled for abutment exchange or removal were consecutively enrolled. The aims were to determine the macroscopic skin signs, the presence of bacteria and the gene expression in abutment-adherent cells and to conduct correlative and comparative analyses between the different parameters. Redness and a granulation ring were present in 47% of the patients...

Recent work has extended the control method of virtual constraints, originally developed for autonomous walking robots, to powered prosthetic legs for lower-limb amputees. Virtual constraints define desired joint patterns as functions of a mechanical phasing variable, which are typically enforced by torque control laws that linearize the output dynamics associated with the virtual constraints. However, the output dynamics of a powered prosthetic leg generally depend on the human interaction forces, which must be measured and canceled by the feedback linearizing control law...

Amputees often experience soft tissue breakdown and discomfort from the high transverse plane shear stresses between the residual limb and prosthesis. To evaluate the effects of varying the transverse plane stiffness, a small sample population of lower limb amputees wore a novel variable stiffness torsion adapter (VSTA). Peak transverse plane moments were evaluated for three fixed stiffness levels (compliant: 0.30Nm/°, intermediate: 0.57Nm/°, stiff: 0.91Nm/°) while participants traversed five tasks of daily living that emphasize transverse plane motion including: straight walking for reference, 90° turns, 180° turns, a static reach test, and the L-Test of functional mobility...

There is preliminary evidence that phantom pain is associated with disturbed organization of the sensory cortex and that this organization can be normalized with two-point discrimination (TPD) training. In this case study, a reduction in phantom pain and painful phantom sensation during a test period of 19 days, was achieved using an automated TPD procedure. In a patient with a transtibial amputation, pain levels decreased from a mean of 2.3/10 on the visual analog scale (VAS) to 1.3/10 (VAS) and the painful phantom sensation level decreased from a mean 3...

BACKGROUND: Acute lower extremity compartment syndrome (CS) is a condition that untreated causes irreversible nerve and muscle ischemia. Treatment by decompression fasciotomy without delay prevents permanent disability. The use of intracompartmental pressure (iCP) measurement in uncertain situations aids in diagnosis of severe leg pain. As an infrequent complication of lower extremity trauma, consequences of CS include chronic pain, nerve injury, and contractures. The purpose of this study was to observe the clinical and functional outcomes for patients with lower extremity CS after fasciotomy...

Amputees using passive ankle-foot prostheses tend to expend more metabolic energy during walking than non-amputees, and reducing this cost has been a central motivation for the development of active ankle-foot prostheses. Increased push-off work at the end of stance has been proposed as a way to reduce metabolic energy use, but the effects of push-off work have not been tested in isolation. In this experiment, participants with unilateral transtibial amputation (N=6) walked on a treadmill at a constant speed while wearing a powered prosthesis emulator...

Amputees are known to walk with greater metabolic cost than able-bodied individuals and establishing predictors of metabolic cost from kinematic measures, such as centre of mass (CoM) motion, during walking are important from a rehabilitative perspective, as they can provide quantifiable measures to target during gait rehabilitation in amputees. While it is known that vertical CoM motion poorly predicts metabolic cost, CoM motion in the medial-lateral (ML) and anterior-posterior directions have not been investigated in the context of gait efficiency in the amputee population...

Knee rotationplasty (KRP) is a type of surgery in which the rotated ankle serves as a new knee after being removed for bone tumor. Although this limb salvage surgery is rarely indicated in properly selected patients, it may offer functional advantages over transfemoral amputation, and more durable results compared with a prosthesis. The walking mechanics of adult patients after KRP is believed to be close to that of below-knee amputees. In this study, we evaluated steady-state walking of KRP patients from the viewpoint of the overall muscle power needed to keep the body centre of mass in motion...

Chronic post-surgical pain impacts the majority of amputees, with more than half experiencing neuralgic residual limb pain. The transition from normal acute post-amputation pain to chronic residual limb pain likely involves both peripheral and central inflammatory mechanisms. As part of the Veterans Integrated Pain Evaluation Research (VIPER) study, we investigated links between systemic inflammatory mediator levels and chronic residual limb pain. Subjects included 36 recent active duty military traumatic amputees with chronic residual limb pain and 40 without clinically significant pain...

OBJECTIVE: Evaluations of physical fitness and efficiency to wheelchair propulsion are common in rehabilitation center. The multistage field test (MFT) was developed for wheelchair users and predicts the peak value of oxygen consumption [Formula: see text] , independently of their impairment [1]. In an earlier study, we did not find significant difference between VO2peak estimated by the Vanderthommen's formula and measured VO2peak [2] of trained wheelchair basketball players. MATERIAL/PATIENTS AND METHODS: Comparatively to wheelchair basketball, the athlete's cardio-respiratory and muscular limitations are greater higher in wheelchair rugby...

OBJECTIVE: A lower limb amputation is a major event for a patient with many questions arising for him and his family. Individual and environmental factors could influence patient's quality of life and adaptation to amputation. Most of the time brochures concern post operative care after limb amputation (surgery type, stump medical care, prosthetics…). Rehabilitation is often only briefly dealt with these brochures. OBJECTIVES OF THIS STUDY: (1) To write a brochure specifically concerning rehabilitation for lower limb amputees...

OBJECTIVE: Intermittent self-catheterization is the gold standard for patients with central neurologic bladder. It allows to reduce all urinary tract complications and to improve the quality of life. The factors of good compliance are continence and autonomy regarding the introduction of the catheter. Nevertheless, self-catheterization can be difficult because of the usual shortcomings associated with bladder and sphincter disorders (motor, sensory…). We found only one study about one adaptive equipment to facilitate the gesture for monoplegic patients...

OBJECTIVE: Following a transfemoral (TF) amputation, the ability to walk with a prosthesis is the main objective of rehabilitation. The achieved speed of walking is considered a determining factor in the amputee's perception of quality of life. This experimental before-after study evaluates the walking abilities and improvement of important parameters such as gait, walking speed, pain and hours of prosthesis use in transfemoral amputees after placing a novel femoral implant that permits distal weight bearing of the residuum within a socket, adapted for distal load bearing...
