Achieving appropriate soft tissue tension around the hip joint is an important factor for achieving hip stability after Total Hip Arthroplasty (THA). Hip instability leads to dislocations, pain, and is a common reason for early revision surgery. The current soft tissue tension assessments available during surgery rely on experience, and...

Background<br/>An upper limb amputee currently has two choices for a body-powered prosthesis, a Voluntary Opening (VO) or Voluntary Closing (VC) hand prosthesis. Which type is best, depends on the task and the individual. Currently, there are no good options for VO and VC in one design. <br/>Objectives<br/>To design a proof-of-principle of a...

Active knee prostheses are potent in assisting users, providing symmetry in walking, reducing metabolic costs, and preventing long-term health problems. The heart of their complex control algorithm employs the Impedance Control (IC) Law, which controls the torque output of the device by three parameters: stiffness coefficient, equilibrium angle,...

Background: Research into prosthesis training and design puts a burden on the small population of people with upper-limb absence who can participate in these studies. One solution is to use a prosthetic hand simulator, which allows for attaching a hand prosthesis to an intact limb. However, whether the results of prosthesis simulator studies...

Running Specific Prosthesis (RSP) allow amputee sprinters to compare to the best able-bodied sprinters in the world. In RSP research, the current state of the art mainly focusses on highly detailed analysis of discrete moments in the sprint, but more data of the entire sprint process in terms of RSP characteristics and sprinting technique are...

<b>Introduction: Prosthesis simulators are essential tools for research and rehabilitation. They can be used to increase the amount of participants in research studies or to assist in rehabilitation. The main goal of this master thesis is to design a functioning prosthesis simulator, which can be used with commonly used...

Many patients with an upper-limb deficiency choose not to wear their prosthetic devices due to a multitude of reasons, including physical discomfort and unintuitive, cognitively demanding control methods. A new haptic interface was developed combining the desirable control characteristics of body-powered control prostheses with the comfort of an...

Objective: The objective of this study was to develop and evaluate a 3D printed hydraulic actuation system, applied in a multi-articulate upper limp prosthesis. The prosthesis was designed to produce sufficient pinch force to be competitive with comparable devices (30 N), and weigh less than a human hand (&lt;0.43 kg). The actuator should...

Nowadays the design of prosthetic hands is mainly focused on myo-electric control for more functionality. And easy producible 3d printed prosthetics to lower the costs of a custom prosthesis. As a result of this change of focus, the body powered prosthetic hands currently on the market are mainly simple clamping mechanisms with no innovative...

Background: Current body-powered hands have very low acceptance rates. They also require high activation forces. In the past, a high acceptance rate was reported for the then-available Hüfner hand, a hand which could be controlled by relatively low activation forces. Objective: The aim of this study was to measure and quantify the mechanical...

Development of a visual prosthesis has the potential to help millions of patients with visual impairment around the world. One approach of visual prostheses is intracortical stimulation, where electrodes penetrating the visual cortex are used to create small light dots in the patients visual field. Said therapy requires an implantable...

OBJECTIVE: This paper describes the design of the BERT Prosthesis and evaluates the proof-of-concept testing for its primary functions. DESIGN: The BERT Prosthesis is an energetically passive, lightweight, transfemoral prosthesis, and four hypotheses about its functional abilities were proposed. TESTING: A simulation of the leg dynamics was...

Introduction: Almost 57 percent of above elbow amputees stop using their prosthesis. One of the main factors of non-wear is the high weight. Pneumatic actuation can be more lightweight than electronic actuation, and might therefore help with reducing the mass of a prosthesis and...

The development of the Delft Cylinder Hand (DCH) demonstrated the design of a lightweight and functional hydraulic body-powered (BP) hand prostheses. The low friction losses of the hydraulics make it an attractive alternative to a classical mechanic transmission using rigid linkages and Bowden cables. There are benefits and trade-offs associated...

Aim: This project aims to design a lightweight, inexpensive and easy to use upper arm prosthesis through improving the design of ARM3D, which is a 3D printed body-powered transhumeral arm prosthesis. This study will cover general shortcomings of body-powered arm prostheses as the weight, cost, amount of parts and limited accessibility of them....

Hoek, A.L. (author)
Hand prostheses commonly advertise on three main selling points: strength, speed and lightweight. Most conventional hand prostheses are only able to combine two of these three attributes. Therefore, combining all three attributes into a single device can result in a commercially attractive hand prosthesis. Another interesting point, particularly...

After en bloc resection of primary pelvic bone tumours, orthopaedic oncologists usually try to perform reconstruction in order to achieve limb salvage. Reconstruction after these types of resections is challenging. Especially when the total ilium and parts of the sacrum needs to be removed. One of the reconstructive options is endoprosthetic...

Prostheses are challenging to obtain in low-income countries due to a lack of experts, remote locations, unfortunate production circumstances and an inadequate amount of research. A 3D printed WILMER open fitting for transradial amputees has been developed, which can solve this problem. It is entirely 3D printed and connects the prosthesis to...

A large proportion of upper extremity prostheses are abandoned by their users. <br/>Commonly, the main reasons for abandonment are related to comfort, control and cosmetics.<br/>Prostheses are often experienced as too heavy and have limited functionality. <br/>A pneumatic power source is able to provide a relatively high force using a small and...
