  • Furthermore, longitudinal studies are needed to investigate the consequences of altered neuromechanics due to knee joint instability on the development of KOA. (eur.nl)
  • The independent variables were age, sex, breadwinner (provide more than 50% income), sport activity level when the knee was pain-free before and after surgery, concomitant meniscal treatment history, Lysholm knee score, desire level for returning to sports. (bvsalud.org)
  • He is recommended by physicians for his quality of waterproofing and his diversity of treating athletes after joint surgery, spine injuries and knee replacements. (hydroworx.com)
  • Keeping the back, hip and knee in an erect line, the heel is brought closer to the hips. (docpods.com)
  • If your pain doesn't improve or interferes with daily tasks, see a health care professional who can prescribe physiotherapy exercises for knee pain. (livestrong.com)
  • An existing, whole body model with detailed anatomical components of the knee (AnyBody) has been adopted and modified for this study. (cdc.gov)
  • Instead, the joint motion involves some translation, in addition to rotation, to more closely mimic anatomical knee motion. (oandp.com)
  • The hip joint model offers limited flexibility, while still maintaining the level of anatomical detail Axis. (anatomywarehouse.com)
  • The knee joint model offers fully functional flexibility, maintaining the level of anatomical detail Axis. (anatomywarehouse.com)
  • We tested our primary hypothesis that a reduction in energy absorption by the lower extremity joints during the loading response would occur, primarily at the knee, when step rate was increased. (nih.gov)
  • Purpose: To examine effects of load carriage and muscular fatigue on lower-extremity joint mechanics during walking. (ed.gov)
  • Lower-extremity joint mechanics were calculated in Visual 3D. (ed.gov)
  • Conclusion: Statistically significant changes in lower-extremity joint mechanics during loaded and fatigued walking may expose military personnel to increased risk for overuse injuries. (ed.gov)
  • More posterior slope potentially helps releasing a too tight flexion gap and it is generally associated with a wider range of post-operative knee flexion. (researchgate.net)
