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...

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....

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...

Background Despite its high demand, prostheses are too often abandoned because they fail to meet the main requirements control, comfort and cosmesis. Body-powered hook prostheses provide good control due to their proprioceptive feedback but are in general not efficient nor appealing. The WILMER group has developed an appealing voluntary-opening...

Upper limb amputees, using a body-powered prosthesis, generate energy with their shoulders which leads to opening or closing of the prosthesis. The preference for one of these types, voluntary opening (VO) or voluntary closing (VC), differs for individuals and for task specifics. Research is, therefore, done regarding terminal devices which...

This project investigates the needs of diabetic and vascular amputees to establish design criteria for a new lower-limb prosthesis liner specifically for diabetes and vascular patients. Initially, a literature review was conducted to investigate liner material properties and outcomes during use, as well as how often diabetic and older amputees...

Conventional passive prosthetic feet cannot provide net positive mechanical energy, causing a strong reduction in push-off work. This decrease the comfortable walking speed and increases the metabolic cost of walking in amputees, as more than half of the positive work performed during able-bodied gait is done during the powered plantar flexion...

Children missing an upper limb face a wide range of issues. Besides the difficulties adult prosthetic users face, such as unsatisfactory function, comfort, and appearance, children also have to deal with the challenges associated with growth. The goal of this thesis was to design an appealing solution for these growing children with an upper...

This graduation project was started on the observation that most orthopaedic companies seem to be still far away from producing 3D printed sockets for customers. Research into manual and digital manufacturing methods resulted in an overview of the possibilities for integrating digital tools into the socket production process. Together with the...

Coehoorn, H.H. (author)
The field of upper limb prosthetics focuses on the development of artificial replacement devices for upper limb loss, from partial finger loss to amputation of the entire arm at the shoulder. Hand and hook prostheses are designed to replace the functionality of a missing hand and can be powered either by external sources (e.g. electricity) or by...

Background: Aseptic loosening [AL] of cementless implants is causing approximately 60% of total knee and total hip arthroplasty revisions. AL is caused among other factors by micromotion. The result is that the bone around the prosthesis is replaced by a fibrous membrane. This fibrous membrane allows for more micromotion and we thus enter a...

Oates, K.E. (author)
Upper-limb prosthetic device rejection rates have been estimated at up to 26\% for adult users and up to 45\% for pediatric users, while non-wear rates are estimated at 20\% and 16\%, respectively. Yet, upper-limb prostheses are of focus in only 20\% of the reviewed published literature (60\% less than lower-limb prostheses), with less than half...

The lower leg stump is not a stable volume. Volume changes during the day between -10% and +5% may occur and these are caused by fluid movements in the stump. These volume changes can mess up a good fitting prosthetic socket and this can lead to pain and injuries. A new invention called “Unimode Beams” solves this issue by placing over 100 beams...

This graduation project describes the results of an exploratory research and design study, focused on developing a patient-specific prosthesis for resurfacing of the distal radius, for patients suffering from wrist osteoarthritis. Pain and limitations in wrist movements are common problems for patients suffering from osteoarthritis. The current...

The vast developments in the electronic industry over the past few decades have provided smaller and lighter electrical components that spurred advances in dexterous upper extremity prostheses. Prosthetic companies have commercialized anthropomorphic artificial hands including over 10 different grasp patterns and auto grasp features to prevent...

The available shoulder harness controlled prostheses do no fulfill the requirements of the users. It is unknown for which operating forces and cable displacements the user can make good use of proprioceptive feedback without feeling pain, discomfort or fatigue. These operating forces and cable displacements can be related to grasping forces and...

Available pressure regulators are considered too heavy for application in pneumatic prostheses. Goal of this paper is developing a lighter pressure regulator adapted for this speci?c application. We present an ultralight mechanical pressure regulator with several possible con?gurations as well as an optimization strategy for easy adaptation of...
