1. 1. Does attentional focus influence performance and motor control on a gross motor task performed with the legs among healthy individuals and individuals with anterior cruciate ligament reconstruction? : A within subject design pilot study

   Kandidat-uppsats, Umeå universitet/Institutionen för samhällsmedicin och rehabilitering

   Författare :Leon Haegerström; Jens Jakobsson; [2023]
   Nyckelord :Attentional focus; External focus; Internal focus; Motor contor; Motor performance; Anterior cruciate ligament reconstruction;

   Sammanfattning : Background: Evidence indicates that an external focus (EF) of attention on the intended effect of one’s movement results in better motor performance and motor control than an internal focus (IF) on one’s own body. Despite this, an IF is predominantly encouraged through instructions and feedback provided by clinicians during sports and rehabilitation from injuries such as anterior cruciate ligament (ACL) injury.

3. 2. Real-time adaptation of robotic knees using reinforcement control

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

   Författare :Leifur Daníel Sigurðarson; [2023]
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

4. 3. Feasibility of Mobile Phone-Based 2D Human Pose Estimation for Golf : An analysis of the golf swing focusing on selected joint angles

   Master-uppsats, KTH/Medicinteknik och hälsosystem

   Författare :Elisa Perini; [2023]
   Nyckelord :Golf; Human Pose Estimation; Sports Analytics; Computer Vision; Golf; Mänsklig Poseuppskattning; Sportanalys; Datorseende;

   Sammanfattning : Golf is a sport where the correct technical execution is important for performance and injury prevention. The existing feedback systems are often cumbersome and not readily available to recreational players. To address this issue, this thesis explores the potential of using 2D Human Pose Estimation as a mobile phone-based swing analysis tool. LÄS MER

5. 4. Assessment of Lower Limb Muscle Strength: Feasibility and Implementation on Exxentric’s SingleExx Machines

   Master-uppsats, KTH/Medicinteknik och hälsosystem

   Författare :Maximilian Geisler; [2023]
   Nyckelord :Force measurement; Lower limb strength; Symmetry assessment; Flywheel-based leg extension machine; Prototype development; Isokinetic dynamometer; Kraftmätning; Styrka i nedre extremiteterna; Symmetribedömning; Flywheel- baserad benförlängningsmaskin; Prototyputveckling; Isokinetisk dynamometer;

   Sammanfattning : Measuring lower limb strength and symmetry is a common practice in elite sports to determine the return to sports point in time during rehabilitation, and this information could be useful for amateur athletes too. However, the devices used for this are highly sophisticated and hardly accessible. LÄS MER

7. 5. Strength testing based automatic scaling of muscle-tendon parameters for musculoskeletal models : An automated method of scaling subject specific muscle-tendon parameters of thigh muscles

   Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

   Författare :Jan Czarnowski; [2022]
   Nyckelord :Simulation; Anybody Modelling Software; Skiing;

   Sammanfattning : A method of estimating subject specific muscle parameters of musculoskeletal models of elite athletes (skiers) was sought. Subject specific models are necessary due to large differences in general anatomy and physical performance of elite athletes relative the general population. LÄS MER
