BACKGROUND: In Iranian orthotic and prosthetic workshops, the majority of activities are carried out by manpower and the tasks are labor-intensive. In these workshops, ergonomic aspects of working conditions are seldom considered. OBJECTIVE: This study was conducted in orthotic and prosthetic workshops with the objectives of determination of prevalence rate of MSDs among employees and assessment of ergonomics working conditions. METHODS: In this cross-sectional study, all employees (n = 42; 29 males and 13 females) in 11 active orthotic and prosthetic production centers of Shiraz city participated...

The introduction of additive manufacturing (AM), often referred to as three-dimensional (3D) printing, has initiated what some believe to be a manufacturing revolution, and has expedited the development of the field of biofabrication. Moreover, recent advances in AM have facilitated further development of patient-specific healthcare solutions. Customization of many healthcare products and services, such as implants, drug delivery devices, medical instruments, prosthetics, and in vitro models, would have been extremely challenging-if not impossible-without AM technologies...

The large, late-stance energy generated by the ankle is believed to be critical during gait. However, the distal foot absorbs/dissipates a considerable amount of energy during the same phase. Thus, the energy generated by the combined ankle-foot system is more modest, which raises questions regarding the necessity of such a large ankle power and the interplay between foot and ankle energetics. This study aimed to evaluate our conservation of energy hypothesis, which predicted if distal foot energy absorption/dissipation was reduced, less energy would be generated at the ankle and thus the same combined ankle-foot energetics would be achieved...

Myoelectric signals (MES) have been used in various applications, in particular, for identification of user intention to potentially control assistive devices for amputees, orthotic devices, and exoskeleton in order to augment capability of the user. MES are also used to estimate force and, hence, torque to actuate the assistive device. The application of MES is not limited to assistive devices, and they also find potential applications in teleoperation of robots, haptic devices, virtual reality, and so on...

Persons with disabilities constitute one of the most vulnerable groups in every society; their identification, assessment and care present a major challenge. In 2001-2003, Cuba conducted the first comprehensive national study of persons with disabilities in the Americas. In 2007-2010, the study was replicated in Bolivia, Ecuador, Nicaragua, Saint Vincent and the Grenadines, and Venezuela, at their governments' request. Study results have enabled implementation of strategies with substancial impact on human health in these countries...

BACKGROUND: Any defect in the extremities of the body can affect different life aspects. The purpose of this study was to investigate the effect of Roy's adaptation model-guided education on coping strategies of the veterans with lower extremities amputation. METHODS: In a double-blind randomized controlled clinical trial, 60 veterans with lower extremities amputation referring to Kowsar Orthotics and Prosthetics Center of Veterans Clinic in Tehran, Iran were recruited using convenience method and randomly assigned to intervention and control groups in 2013-2014...

Hand amputation is a traumatic event that dramatically and permanently changes the life of any person who undergoes one. After surgery, the amputee requires a prosthetic device to perform activities of daily living-in particular, tasks requiring grasping and manipulation functions. According to the Washington, D.C.-based Amputee Coalition, there are 1.9 million amputees who use limb prosthetic services and products, and it is estimated that, among them, 500,000 are upper-limb amputees, with approximately 185,000 new amputations every year (www...

While considering the importance of the interface between amputees and prosthesis sockets, we study an anthropomorphic prosthesis socket whose size can be dynamically changed according to the requirements of the residual limb. First, we introduce the structure and function of the anthropomorphic prosthesis socket. Second, we study the dynamic model of the prosthesis system and analyze the dynamic characteristics of the prosthesis socket system, the inputs of an oscillometric pump, and the control mechanism of force-sensitive resistor (FSR) pressure signals...

BACKGROUND: Prosthetic clinics in the United States must attain accreditation in order to receive reimbursement from Medicare. The accreditation process requires clinics to establish and implement performance management plans and quality improvement activities. This report describes the experience of seven prosthetic clinics in collecting patient-reported outcome data and using it to improve quality of services. OBJECTIVES: To describe the experience of prosthetic clinics implementing outcome monitoring and quality improvement activities as part of routine patient care...

BACKGROUND: Many factors can potentially impact pass or fail performance of a certification examination. While studies regarding predictors of success have been conducted in other professions, no such studies have been conducted in prosthetics and orthotics. OBJECTIVES: Determine whether there are significant differences in prosthetics certification examination success or failure based on gender, Carnegie ranking of the institution from where the candidate received the degree, and whether the candidate is extending credential from orthotics to include prosthetics...

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...

The human shoulder is a complicated musculoskeletal structure and is a perfect compromise between mobility and stability. The objective of this paper is to provide a thorough review of previous finite element (FE) studies in biomechanics of the human shoulder complex. Those FE studies to investigate shoulder biomechanics have been reviewed according to the physiological and clinical problems addressed: glenohumeral joint stability, rotator cuff tears, joint capsular and labral defects, and shoulder arthroplasty...

Purpose The Lower Limb Function Questionnaire (LLFQ) was developed as a self-report assessment of lower-limb functional ability for orthotic and prosthetic (O&P) device users to be suitable for a wide range of conditions, cultures, and ages. The measure aims to address an existing gap in tools for the assessment of functional ability in this population. The purpose of this study is to evaluate LLFQ reliability and validity in a sample of young adult O&P users. Methods Adolescents from a secondary school in Kenya completed the LLFQ twice, 6 d apart, and test-retest reliability was assessed using intra-class correlation coefficients...

This paper proposes a novel approach to improve walking in prosthetics, orthotics and robotics without closed loop controllers. The approach requires impedance profiles to be formed in a walker and uses state feedback to update the profiles in real-time via a simple policy. This approach is open loop and inherently copes with the challenge of uncertain environment. In application it could be used either online for a walker to adjust its impedance profiles in real-time to compensate for environmental changes, or offline to learn suitable profiles for specific environments...

This final rule establishes a prior authorization program for certain durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) items that are frequently subject to unnecessary utilization. This rule defines unnecessary utilization and creates a new requirement that claims for certain DMEPOS items must have an associated provisional affirmed prior authorization decision as a condition of payment. This rule also adds the review contractor's decision regarding prior authorization of coverage of DMEPOS items to the list of actions that are not initial determinations and therefore not appealable...
