Gustav Jarl, Nerrolyn Ramstrand
BACKGROUND: The International Classification of Functioning, Disability and Health is a classification of human functioning and disability and is based on a biopsychosocial model of health. As such, International Classification of Functioning, Disability and Health seems suitable as a basis for constructing models defining the clinical P&O process. The aim was to use International Classification of Functioning, Disability and Health to facilitate development of such a model. Proposed model: A model, the Prosthetic and Orthotic Process (POP) model, is proposed...

#7
Elaine Owen, Stefania Fatone, Andrew Hansen
BACKGROUND: When walking in footwear with a positive "heel sole differential", the sagittal kinematics of the base of the footwear appear to mimic normal barefoot foot kinematics, creating an "effective foot," yet sagittal shank, thigh, and trunk kinematics appear to remain unchanged. These observations have not been quantified. OBJECTIVES: To quantify these observations by assessing the effect of different heel sole differentials on sagittal shank and foot segment kinematics of able-bodied walking...

#8
Andrea J Ikeda, John R Fergason, Jason M Wilken
BACKGROUND: The Intrepid Dynamic Exoskeletal Orthosis is a custom-made dynamic response carbon fiber device. A heel wedge, which sits in the shoe, is an integral part of the orthosis-heel wedge-shoe system. Because the device restricts ankle movement, the system must compensate to simulate plantarflexion and allow smooth forward progression during gait. OBJECTIVES: To determine the influence of wedge height and durometer on the walking gait of individuals using the Intrepid Dynamic Exoskeletal Orthosis...

Nicholas Hale, Maria Valero, Jinghua Tang, David Moser, Liudi Jiang
BACKGROUND: Our hands constantly handle objects throughout our lives, where a crucial component of this interaction is the detection of grasping (pressure) and slipping (shear) of the object. While there have been a large amount of studies using pressure sensors for grasping detection, synchronised pressure and shear detection at the finger/object interface is still needed. OBJECTIVES: This study aims to assess the feasibility of a sensor system designed to detect both pressure and shear at the fingertip/object interface via a single subject test...

Elizabeth Russell Esposito, Christopher A Rábago, Jason Wilken
BACKGROUND: Recent literature indicates equivalent costs of walking can be achieved after a transtibial amputation when the individual is young, active, and/or has extensive access to rehabilitative care. It is unknown if a similar cohort with transfemoral amputation can also achieve lower metabolic costs of walking than previously reported. OBJECTIVE: Compare metabolic cost in individuals with a transfemoral amputation to controls and to the literature across a range of walking speeds...

BACKGROUND: Active individuals with transfemoral amputations are provided a microprocessor-controlled knee with the belief that the prosthesis reduces their risk of falling. However, these prostheses are expensive and the cost-effectiveness is unknown with regard to falls in the transfemoral amputation population. The direct medical costs of falls in adults with transfemoral amputations need to be determined in order to assess the incremental costs and benefits of microprocessor-controlled prosthetic knees...

BACKGROUND: The International Classification of functioning, disability and health refers capacity to what an individual can do in a standardised environment and describes performance as what an individual really does and whether the individual encounters any difficulty in the real-life environment. Measures of capacity and performance can help to determine if there is any gap between them that may restrict participation. The aim of this study was to explore the relationship between capacity scores obtained in a standardised clinical setting and proportional ease of performance obtained from a real-life environment...
