About me

  • Has a PhD on human muscle atrophy and weakness following bedrest inactivity
    or spaceflight (1996), and is the inventor of a strength training apparatus
    (using gravity-independent flywheels) that has been used in microgravity
    studies by ESA and NASA. Also, muscular recruitment and force development
    during strength training and athletics were studied.
    Current studies focus muscular weakness, gait disturbance and morphological
    changes, including muscular fat infiltration, in orthopaedic patients
    suffering from osteoarthritis (OA) of the lower limbs. Not only pain
    alleviation but also restored limb function is nowadays requested after joint
    replacement surgery. We have recently shown profound muscular atrophy and
    weakness in hipOA patients
  • persisting the first 2 years after total hip
    arthroplasty (THA). Hip, thigh and calf muscle atrophy is mapped out using
    computerized tomographic (CT) cross-sections. Maximum force development about
    hip and knee joints are measured using a developed dynamometer.
    Another project studies the development and use of a small (focal) knee joint
    implant for small joint lesions Effective treatment methods for small
    cartilage defects is lacking. Young individuals may develop chronic
    disability following focal joint damages during sport, in the workplace or
    traffic accidents. A new implant and instruments has been developed within a
    Swedish medical technology project and used in pilot study in sheep. Bone
    ingrowth and cartilage wear is monitored.
