Table 1 Paired comparisons of muscle strength, proprioception and knee loading between the limbs

From: Asymmetries and relationships between dynamic loading, muscle strength, and proprioceptive acuity at the knees in symptomatic unilateral hip osteoarthritis

  Ipsilateral limb Contralateral limb Pvalue
Unilateral hip OA (entire group, n = 62)    
  Quadriceps muscle strength (Nm/kg) 0.95 ± 0.35 1.08 ± 0.41 0.006*
  Proprioception (degrees error) 4.7 ± 2.8 5.0 ± 3.0 0.486
  Dynamic loading/KAM (%BW*Ht) 2.23 ± 0.81 2.46 ± 0.71 0.029*
End-stage hip OA (subgroup, n = 25)    
  Quadriceps muscle strength (Nm/kg) 0.89 ± 0.23 1.08 ± 0.39 0.010*
  Proprioception (degrees error) 4.8 ± 3.1 6.0 ± 3.3 0.022*
  Dynamic loading/KAM (%BW*ht) 2.14 ± 0.80 2.53 ± 0.85 0.022*
  1. All values are mean ± standard deviation (SD); *P <0.05. OA, osteoarthritis; Nm, external moments; KAM, knee adduction moment; BW, body weight; Ht, height.
