Filter by:Background and rational: A large number of instruments exists to assess upper limb prosthetic function. However, they differ substantially in terms of psychometric properties and content. Furthermore, there is no "gold standard" and nearly every single center uses a unique set of instruments. This fact prevents the linking of the commonly small (due to the limited number of patients in each center) data sets of different centers and makes comparisons between different fittings or treatment protocols difficult. To generate accepted evidence, we need large data sets with similar outcomes. With remarkable progress made in prosthetic research and rehabilitation in the recent years, the need to evaluate the impact of this intervention on daily life, including productivity, self-care and leisure becomes increasingly relevant. Moreover, self-reported instruments and observation-based instruments exist, but there is a lack of data if, for example, the self-reported instrument (which is easier and less health-professional's-time-consuming to perform) could "replace" a performance or observation-based instrument. Therefore, the aim of this study is to determine psychometric properties of the existing instruments (SHAP, DASH, SF-36 and ACMC) in a large international data set, to explore possible linkage between self-reported and performance or observation-based instruments and to develop state-of-the art recommendations/points to consider on how to assess functioning in prosthetic care.
The purpose of the study is to assess the effectiveness of an upper extremity prosthesis in improving the upper extremity function of children with cerebral palsy who have limited use of their hands. Twelve children, aged 4-17 years, who have cerebral palsy and limitations in their ability to use their hands, will be enrolled. All participants will be fitted with a 3D printed arm/hand prosthesis and receive 8 occupational therapy sessions. Each subject will be evaluated pre-treatment, post-occupational therapy sessions and at 6 months follow-up. The evaluation will include assessment of (1)passive and active arm/hand movement and (2)functional hand skills using several standardized tests. The results from the pre-treatment and the two post-treatment evaluations will be compared.
Subjects are being asked to participate in this study because they have an arm or leg amputation and have developed pain related to a neuroma (an ongoing localized pain related to a cut nerve ending). The investigators are studying how targeted reinnervation (TR) helps to both treat neuroma pain and to have increased prosthetic control. This surgery connects these cut nerve endings to nerves going into nearby nonfunctional muscles. This surgery was developed to allow amputees to have better prosthesis control. By chance, neuroma pain improved significantly with TR. The investigators, therefore, are conducting this clinical trial. The investigators will ask all participants to fill out a questionnaire both before and after surgery. This will help us understand how a neuroma affects the quality of life of amputee will allow us to understand how to best improve neuroma pain and prosthesis control. In order to confirm the presence and location of the neuroma before surgery, a magnetic resonance image (MRI) will be performed. Taking these pictures requires subjects to lie still for a short period of time but does not involve any invasive procedures.
This study is investigating the influence of several simulated real life conditions on the symmetry of gait with trans-tibial prostheses Hypotheses: It is hypothesized that the observable differences in gait pattern between amputees can be detected by a combination of forces and moments that are measured internally in the prosthesis, and electromyography data. It is further hypothesized that changing conditions such as uneven walking surface, prosthetic misalignment or user fatigue are characterized by typical values in the measured data or combinations thereof.
