title: [Control study for muscle force and component of body of female patients with knee osteoarthritis].
abstract: OBJECTIVE
  To understand the information of female patients with knee osteoarthritis regarding muscle force, constitution parameter.
  
  
  METHODS
  Thirty-seven cases diagnosed as knee osteoarthritis and 37 controls were examined by MES. T-test was used to analysis two groups differences of muscle force, constitution parameter, et al.
  
  
  RESULTS
  Compared between affected limbs and controls limbs in patients revealed that the lower limb muscle distribution index of the affected limbs was higher than the control limbs (P<0.05), but comparison in functional status the lower limb muscle force, muscle functional index and muscle force of unit volume of the affected limbs were lower than the control limbs (P<0.05). Compared between patients group and control group the muscle force of both lower limbs, muscle functional index and muscle force of unit volume were lower than control group (P<0.001).
  
  
  CONCLUSIONS
  The utility muscle force of lower limbs of female patients with knee osteoarthritis is weaker than healthy female. Muscle function disorder instead of muscle atrophy is the key cause of the weakness.
