2. 1. Biomechanical assessment of head and neck movements in neck pain using 3D movement analysis

   Author : Helena Grip; Gertjan Ettema; Umeå universitet; []
   Keywords : movement analysis; kinematics; helical axis; neck pain; whiplash; cervical spine; pattern classification; motor control; head-eye co-ordination; head movement; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

   Abstract : Three-dimensional movement analysis was used to evaluate head and neck movement in patients with neck pain and matched controls. The aims were to further develop biomechanical models of head and neck kinematics, to investigate differences between subjects with non-specific neck pain and whiplash associated disorders (WAD), and to evaluate the potential of objective movement analysis as a decision support during diagnosis and follow-up of patients with neck pain.

4. 2. Movement strategies and dynamic knee control after anterior cruciate ligament injury : a three-dimensional biomechanical analysis

   Author : Jonas L. Markström; Charlotte K. Häger; Eva Tengman; Helena Grip; Lina Schelin; Jim Richards; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anterior cruciate ligament; biomechanics; kinematics; kinetics; finite helical axis; injury prevention; sports; reliability; agreement; one-leg hops; functional data analysis; physiotherapy; fysioterapi;

   Abstract : Background: Rupture of the anterior cruciate ligament (ACL) is common and mainly occurs in non-contact situations in sports, often due to momentarily poor movement control. Assessment of movement quality during sport-like tasks iscrucial to understand how to decrease the high risk of reinjury for ACL-injured persons, but also how to prevent primary injury. READ MORE
