  1. 1. Rehabilitation following bone-patellar tendon-bone graft ACL reconstruction

    Författare :Christina Mikkelsen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :ACL injury; ACL reconstruction; ACL rehabilitation; Anterior knee laxity; Closed kinetic chain; Extension deficit; Functional outcome score; Gender; Hyperextension brace; Isokinetic open kinetic chain; KOOS; KT-1000 arthrometer; Patello femoral pain; Personality characteristics; Physical activity; Quadriceps torque; Range of motion;

    Sammanfattning : The overall purpose of this Thesis was to improve treatment and rehabilitation after anterior cruciate ligament (ACL) reconstruction with bone-patellar tendon-bone graft. Study I: The purpose of this study was to evaluate and compare closed kinetic chain (CKC) training and a combination of closed and open kinetic chain (OKC) quadriceps exercises following ACL reconstruction on anterior knee laxity and isokinetic muscle torque.

  3. 2. Sagittal plane knee motion during activity in the anterior cruciate ligament deficient knee

    Författare :Joanna Kvist; Alf Thorstensson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : A complete rupture of the anterior cruciate ligament (ACL) results in static and often in functional instability. After an ACL-injury, most patients have to decrease their activity level, while some can cope with their injury and manage to keep a high activity level. LÄS MER

  4. 3. 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.

  5. 4. Elite sprinters, ice hockey players, orienteers and marathon runners : isokinetic leg muscle performance in relation to muscle structure and training

    Författare :Christer Johansson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electromyography; endurance; enzyme histocytochemistry; fatigue; ice hockey; isokinetic; muscle contraction; OBLA; orienteering; running;

    Sammanfattning : In male athletes from different sports, isokinetic knee extensor, and in orienteers also plantar flexor peak torque (PT), contractional work (CW) and integrated surface electromyograms (iEMG) were analysed.Single contraction PT, CW and iEMG in sprinters and marathon runners were signi­ficantly correlated to the cross-sectional area (CSA) of m.

  7. 5. Muscle injury and pain : effects of eccentric exercise, sprint running, forward lunge and sports massage

    Författare :Sven Jönhagen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Muscle injury; muscle pain; DOMS; eccentric; massage; sprint runner; EMG;

    Sammanfattning : Muscle injuries are the most common injury in sports and both athletes and non-athletes are commonly seen in general practice and in the emergency department. Muscle pain is a common cause for absence from work and the cost to society is high. LÄS MER
