2. 6. Methods for measuring physical workload with relevance for musculoskeletal disorders of neck and upper limb

   Author : Gert-Åke Hansson; Avdelningen för arbets- och miljömedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; shoulder; exposure-response relation; exposure; repetitiveness; movements; postures; questionnaire; EMG; electromyography; accelerometer; Goniometer; inclinometer; arm; wrist; hand.; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

   Abstract : Work-related musculoskeletal disorders of the neck and upper limb are a major problem. Women in repetitive manual work is one large affected group. Preventive actions are hampered by the lack of knowledge regarding quantitative exposure-response relations for physical workload. READ MORE

4. 7. Development of breastfeeding behavior in preterm infants : Behavioral and neurophysiological evidence of early competence

   Author : Kerstin Hedberg Nyqvist; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; Behavior; breastfeeding; development; electromyography; infant; mother; newborn; nurse; observation; oral; preterm; reliability; sucking; validity; Obstetrik och kvinnosjukdomar; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; pediatrik; Pediatrics;

   Abstract : The objectives of this thesis were to develop a method for observation of maturational steps in preterm infants' breastfeeding behavior, test the reliability and validity of this method, describe this development and explore effects of certain infant and maternal factors on infant breastfeeding behavior. The Preterm Infant Breastfeeding Behavior Scale (PIBBS) was developed. READ MORE

5. 8. Identification of single motor units in ultrafast ultrasound image sequences of voluntary skeletal muscle contractions

   Author : Robin Rohlén; Christer Grönlund; Jun Yu; Dario Farina; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultrafast ultrasound; motor units; decomposition; skeletal muscle; voluntary contractions; electromyography; twitch; imaging;

   Abstract : The central nervous system controls human force production by successive recruitment of motor units in the skeletal muscles and changing their neural firing rate. The motor unit comprises a motoneuron, its innervated muscle fibers, and its axons. READ MORE

6. 9. 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

7. 10. Dynamic knee stability after anterior cruciate ligament injury : Emphasis on rehabilitation

   Author : Sofi Tagesson (Sonesson); Joanna Kvist; Birgitta Öberg; Suzanne Werner; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rehabilitation; anterior cruciate ligament; knee joint; joint instability; muscle strength; electromyography; ACL reconstruction; Physiotherapy; Sjukgymnastik fysioterapi;

   Abstract : Anterior cruciate ligament injury leads to increased sagittal tibial translation, and perceptions of instability and low confidence in the knee joint are common. Many patients have remaining problems despite treatment and are forced to lower their activity level and prematurely end their career in sports. READ MORE
