BACKGROUND: Assistive products are items which allow older people and people with disabilities to be able to live a healthy, productive and dignified life. It has been estimated that approximately 1.5% of the world's population need a prosthesis or orthosis. OBJECTIVE: The objective of this study was to systematically identify and review the evidence from randomized controlled trials assessing effectiveness and cost-effectiveness of prosthetic and orthotic interventions...

PURPOSE: There remains a paucity of information regarding the treatment outcomes of dislocation after metacarpophalangeal (MCP) joint arthroplasty. The purpose of this study was to assess the outcomes of surgical and nonsurgical treatment modalities of MCP arthroplasty dislocations. METHODS: Of 816 MCP joint arthroplasties over a 14-year period, there were 37 (4%) acute MCP joint dislocations that required intervention by a health care professional. Implants involved included 28 nonconstrained implants including pyrocarbon (n = 17) and surface replacement arthroplasty (n = 11), and 9 silicone implants...

The walking mechanism of a prosthetic leg user is a tightly coordinated movement of several joints and limb segments. The interaction among the voluntary and mechanical joints and segments requires particular biomechanical insight. This study aims to analyze the inter-relationship between amputees' voluntary and mechanical coupled leg joints variables using cyclograms. From this analysis, the critical gait parameters in each gait phase were determined and analyzed if they contribute to a better powered prosthetic knee control design...

OBJECTIVE: This study investigates the direct comparison of energy cost, efficiency, and effort between an ankle-foot orthosis (AFO) and a functional electrical stimulation (FES) device for foot drop in ambulatory patients with multiple sclerosis. DESIGN: Twenty adults (32-74 years old; 55% female) with a diagnosis of multiple sclerosis resulting in foot drop participated in a crossover, counterbalanced preliminary study. Each participant was tested on different days, with each session consisting of a separate walk trial per prosthetic device...

Modeling and simulation of prosthetic devices are the new tools investigated for the production of total customized prostheses. Computational simulations are used to evaluate the geometrical and material designs of a device while assessing its mechanical behavior. Data acquisition through magnetic resonance imaging, computed tomography or laser scanning is the first step that gives information about the human anatomical structures; a file format has to be elaborated through computer-aided design software. Computer-aided design tools can be used to develop a device that respects the design requirements as, for instance, the human anatomy...

BACKGROUND: The question whether or not a patient with a hip brace should drive a car is of obvious importance because the advice given to patients to resume driving is often anecdotal as few scientific data are available on this specific subject. OBJECTIVES: To assess driving ability (brake response time) with commonly used hip braces. STUDY DESIGN: Repeated measures design. METHODS: Brake response time was assessed under six conditions: (1) without a brace (control), (2) with a typical postoperative hip brace with adjustable range of motion and the settings: unrestricted, (3) flexion limited to 70°, (4) extension blocked at 20° hip flexion, (5) both flexion and extension limited (20°/70°) and (6) an elastic hip bandage...

A powered lower extremity orthotic brace can potentially be used to assist frail elderly during daily activities. This paper presents a method for an early detection of the initiation of sit-to-stand (SiSt) posture transition that can be used in the control of the powered orthosis. Unlike the methods used in prosthetic devices that rely on surface electromyography (EMG), the proposed method uses only sensors embedded into the orthosis brace attached to the limb. The method was developed and validated using data from a human study with 10 individuals...

BACKGROUND AND OBJECTIVES: Assessing patient satisfaction with orthosis (PSwO) is a key point for clinical practice to increase a patient's adherence to therapeutic programs and reduce orthotic-related costs. The Client Satisfaction with Device (CSD) module of the Orthotics and Prosthetics Users' Survey (OPUS) is one of the most widely-used questionnaires for assessing PSwO, but its validated version in the Arabic language is lacking. The objective of this study is to generate and psychometrically validate an Arabic version of the CSD (CSD-Ar)...

Noninvasive brain-computer-interfaces (BCI) coupled with prosthetic devices were recently introduced in the rehabilitation of chronic stroke and other disorders of the motor system. These BCI systems and motor rehabilitation in general involve several motor tasks for training. This study investigates the neurophysiological bases of an EEG-oscillation-driven BCI combined with a neuroprosthetic device to define the specific oscillatory signature of the BCI task. Controlling movements of a hand robotic orthosis with motor imagery of the same movement generates sensorimotor rhythm oscillation changes and involves three elements of tasks also used in stroke motor rehabilitation: passive and active movement, motor imagery, and motor intention...

BACKGROUND: Orthotic treatment of idiopathic toe walking is complicated by the lack of a known etiology. This study compared control of toe walking using an articulated ankle-foot orthosis versus a rigid carbon fiber footplate attached to a foot orthosis. OBJECTIVES: Ascertain differences between two orthoses in the control of idiopathic toe walking. STUDY DESIGN: Randomized controlled trial. METHODS: A total of 18 children with idiopathic toe walking were randomized to either the ankle-foot orthosis or foot orthosis treatment group in a Parallel Randomized Controlled Trial with no blinding...

BACKGROUND: Assessment of patient satisfaction with orthosis is a key point for clinical practice and research, requiring questionnaires with robust psychometric properties. OBJECTIVES: To identify which validated questionnaires are used to investigate patient satisfaction with orthosis in limb orthotics and to analyse (1) their main fields of clinical application, (2) the orthosis-related features analysed by the questionnaires and (3) the strength of their psychometric properties...

BACKGROUND: Information on patient satisfaction with orthosis (PSwO) is crucial for verifying and enhancing orthotic quality, for clinical decision making, and for improving patient's quality of life. OBJECTIVE: To perform the translation and cross-cultural adaptation into Italian of the recently revised version of the Client Satisfaction with Device (CSD) module of the Orthotics and Prosthetics Users' Survey, and then analyze its psychometric properties using factor and Rasch analyses...

Congenital fibular deficiency (CFD) is characterized by a wide spectrum of manifestations ranging from mild limb length inequality (LLI) to severe shortening, with foot and ankle deformities and associated anomalies. The etiology of CFD remains unclear. Treatment goals are to achieve normal weight bearing, a functional plantigrade foot, and equal limb length. The recent Birch classification system has been proposed to provide a treatment guide: the functionality of the foot, LLI, and associated anomalies should be taken into account for decision-making...

Ankle foot orthoses (AFOs) are widely used as assistive/rehabilitation devices to correct the gait of people with lower leg neuromuscular dysfunction and muscle weakness. We have developed a portable powered ankle-foot orthosis (PPAFO), which uses a pneumatic bi-directional rotary actuator powered by compressed CO2 to provide untethered dorsiflexor and plantarflexor assistance at the ankle joint. Since portability is a key to the success of the PPAFO as an assist device, it is critical to recognize and control for gait modes (i...

STUDY DESIGN: Literature Review BACKGROUND: We estimate that over 29 million people worldwide in resource-limited environments (RLEs) are in need of orthotic and prosthetic (O&P) devices and services. OBJECTIVES: Our goal was to ascertain the current state of O&P provision in RLEs and identify factors that may lead to more successful O&P provision. METHODS: We conducted a comprehensive scoping literature review of all information related to O&P provision in RLEs published from 2000 to 2010...
