  1. 1. The data-driven CyberSpine : Modeling the Epidural Electrical Stimulation using Finite Element Model and Artificial Neural Networks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Yu Qin; [2023]
    Nyckelord :Spinal Cord Injury; Epidural Electrical Stimulation; Computational Neuroscience; Finite Element Model; Artificial Intelligence; Optimal Transport; EMG; Muscle Activation; Ryggmärgsskada; Epidural Elektrisk Stimulering; Beräkningsneurovetenskap; Finita Elementmodellen; Artificiell Intelligens; Optimal Transport; EMG; Muskelaktivering;

    Sammanfattning : Every year, 250,000 people worldwide suffer a spinal cord injury (SCI) that leaves them with chronic paraplegia - permanent loss of ability to move their legs. SCI interrupts axons passing along the spinal cord, thereby isolating motor neurons from brain inputs. To date, there are no effective treatments that can reconnect these interrupted axons. LÄS MER

  3. 2. Evaluation of the DXA radiation environment at Sahlgrenska University Hospital

    Master-uppsats,

    Författare :Saga Söderholm; [2022-05-18]
    Nyckelord :Medical physics; DXA; DEXA; Dual-energy X-ray absorptiometry; Bone mineral density;

    Sammanfattning : Purpose: The aims of this work were to evaluate the radiation environment in the dual-energy X-ray absorptiometry (DXA) rooms at Sahlgrenska University Hospital, estimate personnel doses, determine legal requirements for DXA personnel, examine the operators’ view on radiation safety and develop material with dose information for patients and operators. Theory: DXA is a low dose X-ray modality mainly used in osteoporosis examinations, for which it is considered the reference technique. LÄS MER

  4. 3. Ambulanssjuksköterskans upplevelser av spinal rörelsebegränsning : En intervjustudie

    Magister-uppsats, Linnéuniversitetet/Institutionen för hälso- och vårdvetenskap (HV)

    Författare :Nina Jönsson; Emelie Stackelberg; [2022]
    Nyckelord :The ambulance nurse; experiences; care; spinal injury; spinal restriction; trauma; Ambulanssjuksköterskan; upplevelser; omhändertagande; spinal skada; spinal rörelsebegränsning; trauma;

    Sammanfattning : Bakgrund: Trauma förekommer över hela världen och olyckor står för den främsta dödsorsaken hos personer under 45 år, både internationellt och nationellt. Trauma är en av de vanligaste orsakerna till akuta skador i halskotpelaren och halsryggmärgen. LÄS MER

  5. 4. DEFORMABLE IMAGE REGISTRATION OF SPINE MAGNETIC RESONANCE IMAGES WITH ELASTIX FOR DETAILED CHARACTERIZATION OF DISC LOADING BEHAVIORS

    Master-uppsats,

    Författare :Zainab Sirat; [2021-05-10]
    Nyckelord :Medical physics; Registration; MRI; Spine;

    Sammanfattning : Purpose: This work aimed to develop an optimized strategy for registration of spine magnetic resonance (MR) images acquired with and without spinal loading, as well as evaluate the quality of the registration strategy with commonly used quality assessment methods. Method: Previously collected MR images of the lumbar spine of 37 individuals were re analyzed. LÄS MER

  7. 5. Development, Modelling and Investigation of a Robotic Exoskeleton for Astronaut Back Support

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Evert Häggman; [2021]
    Nyckelord :Exoskeleton; Musculoskeletal Disorders; Biorobotics; Astronaut;

    Sammanfattning : Musculoskeletal disorders, specifically low back pain, has been well documented andreported by astronauts throughout the space exploration era. Statistics from astronautmemoirs states that 52-68% of astronauts experience moderate to severe lower backpain after prolonged spaceflights. LÄS MER
