2. 26. Dual-Arm Robotic Manipulation under Uncertainties and Task-Based Redundancy

   Author : Diogo Almeida; Yiannis Karayiannidis; Fabrizio Caccavale; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Robotic manipulators are mostly employed in industrial environments, where their tasks can be prescribed with little to no uncertainty. This is possible in scenarios where the deployment time of robot workcells is not prohibitive, such as in the automotive industry. READ MORE

4. 27. Bias and Precision in Biomechanical Exposure Assessment : Making the Most of our Methods

   Author : Jennie Jackson; Svend Erik Mathiassen; Eva Vingård; Mikael Forsman; Peter Johnson; Högskolan i Gävle; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; measurement strategy; accuracy; inclinometry; electromyography; EMG; upper arm; shoulder; low back; lumbar; thoracic; Health-Promoting Work; Hälsofrämjande arbete;

   Abstract : Background: Insufficient exposure assessment is a suggested contributing factor to the current lack of clearly characterised relationships between occupational biomechanical risk factors and musculoskeletal disorders. Minimal attention has been paid to the potential bias of measurement tools from expected true values (i.e. READ MORE

5. 28. Efficient strategies for collecting posture data using observation and direct measurement

   Author : Per Liv; Svend Erik Mathiassen; Marina Heiden; Leif Nilsson; Ingvar Bergdahl; Stephen Bao; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exposure assessment; arm elevation; exposure variability; variance components; random effects model; precision; bias; sample size; sample allocation; calibration; bootstrapping; Occupational and Environmental Medicine; arbets- och miljömedicin;

   Abstract : Relationships between occupational physical exposures and risks of contracting musculoskeletal disorders are still not well understood; exposure-response relationships are scarce in the musculoskeletal epidemiology literature, and many epidemiological studies, including intervention studies, fail to reach conclusive results. Insufficient exposure assessment has been pointed out as a possible explanation for this deficiency. READ MORE

6. 29. Total Shoulder Arthroplasty : clinical and radiological studies on the implant positioning and fixation

   Author : Bakir Kadum; Göran Sjödén; Lars Adolfsson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Total shoulder arthroplasty; reverse shoulder arthroplasty; stemless shoulder arthroplasty; TESS shoulder prosthesis; comprehensive shoulder prosthesis; scapular notching; arm lengthening; Quick DASH; lateral humeral offset; glenohumeral offset; shoulder anatomy; CT shoulder; shoulder anatomy reconstruction.; ortopedi; Orthopaedics;

   Abstract : Shoulder arthroplasty surgery has shown remarkable progress during the last few decades. A number of factors affect postoperative range of motion, pain and prosthetic durability. Among these factors, the length of the lever arm and joint stability is the ones that can be altered by the selected prosthetic component. READ MORE

7. 30. Subject-specific musculoskeletal modeling of the lower extremities in persons with unilateral cerebral palsy

   Author : Olesya Klets; Elena Gutierrez-Farewik; Sven Kleiven; KTH; []
   Keywords : cerebral palsy; moment arm; muscle length; hemiplegic; MRI; subject-specific; musculoskeletal modeling; lower extremities; muscle volume; Mechanical engineering; Maskinteknik;

   Abstract : The computational musculoskeletal models that are used to study muscle moment-generating capacities of persons with movement disorders and planning treatment options must be accurate, and take into account the inter-individual variability of musculoskeletal geometry. In Paper I the methods of creating the subject-specific musculoskeletal model of the lower extremities from magnetic resonance images (MRIs) were developed. READ MORE
