Table 2 GEE analysis of pelvic and thoracic ROM and ratio of thoracic ROM to pelvic ROMa

From: Subjects with hip osteoarthritis show distinctive patterns of trunk movements during gait-a body-fixed-sensor based analysis

Outcome Group Group effect (95% CI) P value Group by walking speed effect (95% CI) P value
Pelvic ROM HC 0b   0  
  NDL -1.5 (-2.3, -0.7) < .001 -2.4 (-3.4, -1.4) < .001
  DL -0.6(-1.8, 0.5) .29 -3.0 (-4.7, -1.2) .001
Thoracic ROM HC 0   0  
  NDL 1.0 (0.4, 1.7) .002 -1.0 (-1.7, -0.3) .005
  DL 5.0 (3.5, 6.4) < .001 -4.4 (-6.4, -2.4) < .001
Ratio HC 0   0  
  NDL 0.5 (0.3, 0.7) < .001 -0.0 (-0.2, 0.1) 0.64
  DL 1.0 (0.7, 1.3) < .001 -0.5 (-0.9, -0.1) .007
  1. Reference group: healthy control group.
  2. a Adjusted for walking speed, age, body height and body weight.
  3. b Set to zero because HC was used as reference group.
  4. indicate significant difference between NDL and DL.
  5. Abbreviations: GEE, generalized estimating equation; HC, healthy control group; NDL, patients without a Duchenne limp; DL, patients with a Duchenne limp.
  6. Thoracic and pelvic ROM are expressed in degrees (°).
