Evaluating the Impact of Prosthetic Device Features on the Experience of Prosthesis Use
Abstract
Our goal is to understand the critical factors associated with outcome acceptance following upper limb loss. We aim to develop a unified theoretical model that describes the psychosocial experience of upper limb prosthesis use and predicts outcome acceptance following upper limb loss. This conceptual framework will enable clinicians and researchers to evaluate and predict patient outcomes following limb loss, and to design interventions that improve outcomes. The specific aims are: 1) Assess the impact of the experience of prosthesis dexterity and control on outcome acceptance, 2) Assess the impact of sensory feedback experience on outcome acceptance, and 3) Refine the theoretical model derived from qualitative analyses by exploring the quantitative relationships between aspects of the model of outcome acceptance. The qualitative analyses will yield a theoretical model of outcome acceptance that includes psychosocial factors and prosthetic device factors related to dexterity, control, and sensory feedback. We hypothesize that experiences of prosthesis dexterity, control, and sensory feedback will both directly influence and modulate psychosocial factors of prosthesis use and user attitudes. We hypothesize that quantitative data collected through survey research will triangulate findings from the qualitative analyses, confirm the directionality of the conceptual relationships, and predict the relative weightings of relationships. During this year, we have hired new personnel to support the study and trained all study staff. We have developed interview guides, recruitment materials, screening processes, and qualitative analysis processes for the qualitative components of the study. We have submitted regulatory documents and received approval from the Central VA IRB. We have conducted mock interviews and developed an initial code set based on an analysis of this mock data.
