  1. 1. Real-time adaptation of robotic knees using reinforcement control

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Leifur Daníel Sigurðarson; [2023]
    Keywords : Machine learning; deep reinforcement learning; transfer learning; medical device; prosthetic; prosthesis; controls; human-in-the-loop; Maskininlärning; djup förstärkningsinlärning; överföringsinlärning; medicinsk utrustning; protes; kontroller; människa-i-loopen;

    Abstract : Microprocessor-controlled knees (MPK’s) allow amputees to walk with increasing ease and safety as technology progresses. As an amputee is fitted with a new MPK, the knee’s internal parameters are tuned to the user’s preferred settings in a controlled environment. READ MORE

  3. 2. An alignment tool for prosthetic components : A conceptual development

    University essay from Jönköping University/HHJ, Avd. för rehabilitering

    Author : Robin Johansson; [2022]
    Keywords : Prosthetics; alignment; malalignment; misalignment; artificial limb; design; product development.; Protes; uppställning; inställning; felställning; konstgjord kroppsdel; design; produktutveckling;

    Abstract : Prosthetic alignment is the principle of the position and orientation and of the components in a lower limb prosthesis to achieve desirable biomechanical characteristics. Poor alignment of lower limb prostheses is related to decreased balance, knee and hip arthritis, and higher energy expenditure for the user. READ MORE

  4. 3. Polymer-based additive manufacturing: optimization for high-performance degradable polymers

    University essay from KTH/Fiber- och polymerteknologi

    Author : Danjing Chen; [2022]
    Keywords : copolymerization; fused filament fabrication; degradable polymer; scaffold; 3D printing; sampolymerisering; tillverkning av filament; nedbrytbar polymer; tredimensionella matriser; 3D printing;

    Abstract : I det här utvecklas en reproducerbar polymerisationsmetod för att uppnå en stabil produktion av poly(ε-caprolakton-co-p-dioxanon) (PCLDX), skala upp filamenttillverkningen för att producera 1.75 mm långa filament och optimera 3D-utskriftsprocessen för att tillverka ställningar/anordningar för mjukvävnadsteknik.

  5. 4. EEG Signal Analysis in the Frequency Domain : An Examination of Abnormalities During the Gait Cycle

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Lou Gripentoft; Zilan Isik; [2022]
    Keywords : EEG; Frequency Domain; Signal Analysis; Fast Fourier transform; EEG; Frekvensdomän; Signalanalys; Snabb Fourier transform.;

    Abstract : Many people experience discomfort during movement when using a knee prosthesis. As a result, a study is being conducted to see if biomedical models can be used to produce an optimal prosthetic socket to reduce discomfort. READ MORE

  6. 5. Exploring Transtibial Prosthesis User’s Satisfaction and Experiences regarding the Appearance of their Cosmesis : A Qualitative Study

    University essay from Jönköping University/HHJ. Ortopedteknisk plattform

    Author : Amal Abdiqadir Salad; Ida Marie Palmgren Pedersen; [2021]
    Keywords : amputation; transtibial; below-knee; cosmesis; satisfaction; appearance; thematic analysis; qualitative  ; amputation; transtibial; under knäet; kosmetik; tillfredsställelse; utseende; tematisk analys; kvalitativ;

    Abstract : Background: Cosmesis has been found to have an impact on prosthesis users' body image. Therefore the satisfaction of the cosmesis plays an essential role in a prosthesis user perception of themselves. Most cosmeses on the market are natural-looking, although more futuristic options are coming to the market. READ MORE
