Patients with hemiplegic cerebral palsy often have noticeably deviant arm posture and decreased arm movement. Here we develop a comprehensive assessment method for the upper extremity during walking. Arm posture score (APS), deviation of shoulder flexion/extension, shoulder abduction/adduction, elbow flexion/extension and wrist flexion/extension were(More)
BACKGROUND Individuals with spastic hemiplegic cerebral palsy are typically high functioning and walk without assistive devices. The involved limb is usually smaller and shorter, although it is not clear whether the difference in muscle volume has an impact on walking capacity. QUESTIONS/PURPOSES We determined the volume of muscles important for(More)
BACKGROUND AND PURPOSE Hip dislocation in children with cerebral palsy (CP) is a common and severe problem. The Swedish follow-up program for CP (CPUP) includes standardized monitoring of the hips. Migration percentage (MP) is a widely accepted measure of hip displacement. Coxa valga and valgus of the femoral head in relation to the femoral neck can be(More)
PURPOSE When treating slipped capital femoral epiphysis (SCFE), a smooth pin with a hook or a short threaded screw can be used to allow further growth, which could be important to prevent the development of impingement and early arthritis. The purpose of this investigation was to measure growth in three dimensions after fixation of SCFE. METHODS Sixteen(More)
BACKGROUND The treatment for length-unstable diaphyseal femur fractures among school-age children is commonly intramedullary elastic nails, with or without end caps. Another possible treatment is the semi-rigid pediatric locking nail (PLN). The purpose of this biomechanical study was to assess the stability of a length-unstable oblique midshaft fracture in(More)
BACKGROUND Precise long-term assessment of movement and physical function following Achilles tendon rupture is required for the development and evaluation of treatment, including different regimens of physical therapy. PURPOSE To assess intermediate-term (<10 years by conventional thinking) objective measures of physical function following Achilles tendon(More)
Elbow flexion in hemiplegic cerebral palsy causes not only a functional impairment but is also a cosmetic concern. We report on the natural history of arm positioning during walking at different ages. One hundred seventy-five children (mean age +/- SD, 9.2 +/- 4.1 years) were assessed by using 3-dimensional gait analysis. The results showed a significant(More)
