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

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

   Author : Yu Qin; [2023]
   Keywords : 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;

   Abstract : 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.

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

   University essay from

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

   Abstract : 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. READ MORE

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

   University essay from

   Author : Zainab Sirat; [2021-05-10]
   Keywords : Medical physics; Registration; MRI; Spine;

   Abstract : 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. READ MORE

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

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Evert Häggman; [2021]
   Keywords : Exoskeleton; Musculoskeletal Disorders; Biorobotics; Astronaut;

   Abstract : 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. READ MORE

6. 5. A Machine Learning-Based Statistical Analysis of Predictors for Spinal Cord Stimulation Success

   University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

   Author : Trolle Jacobson; Gustav Segerberg; [2019]
   Keywords : Machine Learning; Predictors; Spinal Cord Stimulation; SCS; Outcomes;

   Abstract : Spinal Cord Stimulation (SCS) is a treatment for lumbar back pain and despitethe proven effcacy of the technology, there is a lack of knowledge in how the treatment outcome varies between different patients groups. Furthermore, since the method is costly, in the sense of material, surgery and follow-up time, a more accurate patient targeting would decrease healthcare costs. READ MORE
