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

    Författare :Helena Grip; Gertjan Ettema; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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.

  3. 2. Motor control of the knee : kinematic and EMG studies of healthy individuals and people with patellofemoral pain

    Författare :Ann-Katrin Stensdotter; Charlotte Häger-Ross; Gunnevi Sundelin; Gertjan Ettema; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kinematics; Kinetic chain tasks; Knee; Motor Control; Muscle activity; Patellofemoral pain; Unpredictable perturbations; Physiotherapy; Sjukgymnastik fysioterapi;

    Sammanfattning : Patellofemoral pain (PFP) is believed to be associated with deficits in coordination between the different heads of the quadriceps muscle; however, considerable debate exists in the literature regarding the presence of such a deficit. Discrepancies between studies may be explained by differences in experimental tasks, such as whether the task is performed with open (OKC) or closed kinetic chain (CKC), or whether the activity is voluntary or triggered.
