Energy harvesting has gained lots of interest over the past few decades. This study explores the application of energy harvesting in lower limb prosthetic devices. The control system of a lower limb prosthesis includes sensors, wireless<br/>systems and other active components which all require battery power. In order to save some of this battery...

Prosthetic limbs are devices that change users’ lives in every aspect. They allow the wearer to live and be independent again. Nevertheless, despite the numerous benefits, they carry cultural stigmas, as well as physical and mental discomfort, along with various daily challenges. While the functionality and physical comfort of these devices can...

The traumatic loss of a hand is a horrific experience usually followed by significant psychological, functional and rehabilitation challenges. Even though much progress has been made in the past decades, the prosthetic challenge of restoring the human hand functionality is still far from being achieved. Autonomous prosthetic hands showed...

Prostheses and orthoses are trending towards digital methods and automation. Adopting these methods is especially a challenge at Frank Jol, a clinic where patients' wide variety in residual limb characteristics and high activity demands pose a challenge for digital workflows which utilise 3D scanning to arrive at a final prosthesis. This is...

Eighty percent of women after mastectomy wear an external breast prosthesis either permanently or during the period before breast reconstruction. External breast prostheses replace the removed breast and aim to recreate the original body shape. However, while each woman has a different chest wall and scar topology, most commonly used are...

INTRODUCTION: Erectile dysfunction (ED) affects to some degree approximately 52% of the male population aged 40-70 years. Many men do not respond to, or are precluded from using, pharmaceutical treatments for ED and are therefore advised to consider penile prostheses. Different types of penile prosthesis are available, such as inflatable...

Background: The procedure to fit a prosthetic socket to a patient, which can assure the patient’s comfort during activities of daily living, is labour intensive. Such a lengthy procedure could benefit from an automated and more efficient data-driven method capable of automatically tracking the relative movement between the patient’s tibia and...

Fluid-controlled actuators are widely used in lower limb prostheses. Most fluid-controlled actuators have valves integrated into the cylinder systems and require complex manufacturing steps, making these systems expensive. A cost-effective production method for these complex actuator valve systems is 3D-printing. The goal of this research is to...

Introduction - Arthritis is a condition causing pain, deformations and loss of motion in human joints. The surgical instruments used to place a specific unconstrained prosthesis that is used to treat an arthritic joint are difficult to use. The objective for this thesis is to improve the current placement procedure by carrying out an analysis on...

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...

van der Vlist, Klaas Jan (author)
This report shows the development of a method that joins two chemically incompatible materials during Fused Deposition Modelling (FDM). State of the art FDM printers can extrude more than one material during the printing process. Due to chemical incompatibility of many polymers, the selection for combining materials is limited. This gives the...

Various upper-limb prostheses have been designed for 3D printing but only a few of them are based on bio-inspired design principles and many anatomical details are not typically incorporated even though 3D printing offers advantages that facilitate the application of such design principles. We therefore aimed to apply a bio-inspired approach...

Remmerswaal, Evan (author)
Problem: Due to high rejection rates regarding prostheses’ use, the assessment of the amputee’s use of the prosthesis has become more critical. Today’s prosthesis research is limited to assessing a users’ performance to perform tasks in a controlled environment. Therefore, these studies cannot wholly assess how the prosthesis is used in the...

Wearable actuators in lower-extremity active orthoses or prostheses have the potential to address a variety of gait disorders. However, whenever conventional joint actuators exert moments on specific limbs, they must simultaneously impose opposing reaction moments on other limbs, which may reduce the desired effects and perturb posture. Momentum...

Markna, Riho (author)
The work presented in the thesis was motivated by the history of cineplasty and aims to create a supportive system for the body powered upper limb prostheses. A mechanical signal (pulling) from a cineplastic site or a harness system (e.g. shoulder harness) is used to control a prosthetic device. These signals are often too weak to comfortably...

Artificial elbow modules are used in orthoses and prostheses, whereby orthoses correct, align and support the body with skeletal or neuromuscular impairments [1]. Instead, prostheses replace missing body parts and compensate for lost functions [1]. However, most designs do not allow the natural arm swing based on their transmission design or the...

Background: Body-powered prosthesis users frequently complain about the poor cosmesis and comfort of the traditional shoulder harness. The Ipsilateral Scapular Cutaneous Anchor System offers an alternative, but it remains unclear to what extent it affects the perception and control of cable operation forces compared to the traditional shoulder...

Goal: This paper aims to provide an overview with quantitative information of existing 3D-printed upper limb prostheses. We will identify the benefits and drawbacks of 3D-printed devices to enable improvement of current devices based on the demands of prostheses users. Methods: A review was performed using Scopus, Web of Science and websites...

Study Design: Experimental trial. Background: The functional performance of currently available body-powered prostheses is unknown. Objective: The goal of this study was to objectively assess and compare the functional performance of three commonly used body-powered upper limb terminal devices. Methods: Twenty-one able-bodied subjects (n=21, age...

Rejection rates of upper limb prostheses are high (23-45%). Amputees indicate that the highest design priority should be reduction of the mass of the prosthetic device. Despite all efforts, the mass of the new prosthetic hands is 35-73% higher than that of older hands. Furthermore current hands are thicker than a human hand, they operate slower...
