Filter by:The focus of this study is to conduct a clinical study in individuals with transradial amputations to compare function using a 1-DOF or 2-DOF wrist. All prostheses will be attached to a single DOF Otto Bock hand and controlled using a pattern recognition system equivalent to the Coapt system. This study will enable the investigator to quantify the relative functional value of powered wrist flexion during both in-laboratory testing and home use. In addition, the investigators will address the effectiveness of different hand-wrist combinations to enhance patient-centered clinical decision making.
Using a retrospective review of records, we will conduct a multivariate analysis to examine the relationship between exposure to ketamine, as an analgesic agent in combat related trauma care, the use of additional opioid pain medications, and patient reported pain levels.
The objective of the proposed work is to enhance understanding of the potential benefits of adjustable sockets and inform clinical decision making.
This is a prospective study looking to evaluate whether the treatment outcomes for patients who sustain a distal fingertip amputation are improved or no different when using biological dressings versus artificial dressings.
State-of-the-art myoelectric prostheses provide upper limb amputees with a remarkable variety of grip patterns but lack proper feedback from touch sensation. This restriction limits the controllability of multi-articulated robotic hands, resulting in the rejection of the device in many cases. Amputees have often reminiscing sensations in the stump, i.e. by touching certain regions, it feels as if no longer existing fingers were touched. These regions form a phantom map and show promising results for touch feedback. However, not every amputee has one and the socket of a prosthesis offers limited space for additional devices. Thus, the investigators developed a feedback display which is worn in the shoe instead of the prosthesis itself. The investigators want to assess the viability of vibrotactile feedback stimulus on the foot as a substitution for pressure on the fingers of an artificial hand in a clinical study. The efforts are based on the hypothesis that a hand prosthesis with tactile feedback has better performance in manipulating fragile and heavy objects, compared with a standard commercial hand prosthesis without tactile feedback.
Implication and evaluation of a non-invasive sensory feedback system in hand prostheses in everyday life.
The purpose of this study is to develop criteria for prosthetic foot prescription for Veterans and Service Members with transtibial limb loss. The objectives are to: 1) Determine the appropriate functional outcome tests and measures to support the prescription of a type of Energy Storing and Returning (ESR) non-articulating, articulating or active plantarflexion prosthetic ankle-foot for a Veteran or Service Member with transtibial limb loss. 2) Correlate patient goals and subjective measures with objective data to determine the appropriate prosthetic ankle-foot category that will facilitate the greatest overall function to the user. 3) Develop criteria for the appropriate prescription of non-articulating ESR, articulating ESR, and active plantar flexion ESR ankle-foot units.
Objectives: The main objectives are to determine neural dynamics during gait using electro-encephalography as well as brain sources and to investigate the attentional demand during walking in able-bodied individuals, and individuals with an amputation. Materials & Methods: 6 able-bodied individuals conducted one experimental trial, and 6 unilateral transtibial and 6 unilateral transfemoral amputees performed 2 experimental trials; the first with the current and the second with a novel powered transtibial prosthesis, i.e. the Ankle Mimicking Prosthetic foot 4.0. Each experimental trial comprised 2 walking tasks; 6 and 2min treadmill walking at normal speed interspersed by 5min of rest. During 6min walking the sustained attention to response (go-no go) task, with measures reaction time and accuracy, was performed. Electro-encephalographic (EEG) data were gathered when subjects walked 2min. Motor-related cortical potentials and brain activity during gait are extracted using EEG.
The trial is designed to test the effectiveness of a force-feedback cuff in combination with a myoelectric prosthesis in conveying information on grasp strength to the user, as well as the user's preference regarding the feature.
Upper extremity allotransplantation is a new procedure which is becoming more common in the United States. Ongoing data collection for research purposes is vital to the long-term assessment as to the safety of the procedure and accompanying immunosuppression protocol, as well as quantifying patient outcomes and changes in quality of life. For these reasons, The Johns Hopkins Hand/Arm Transplantation Team is interested in enrolling transplanted patients in a follow-up protocol to continue collecting informative data to further the field of vascularized composite allotransplantation.
