Background: Crouch gait pattern in Cerebral Palsy is defined as flexion of hip, knee with excessive dorsiflexion of ankle, however less importance is given to the Pelvic tilts either anterior or posterior, which could be due to contracture of Rectus and hamstring respectively. Purpose: The aim of the study is to correlate the clinical parameters with Gait kinematics of Pelvis, hip and knee in crouch gait in cerebral palsy. Methods: 64 patients of SDCP with crouch gait pattern (Males 47, females 17), with an average age group of 14.2 years, GMFCS level 2 and 3 were included in this study. These patients underwent a 3D gait analysis. Results: The presence of Hip FFD in 16.7% or absence in 83.3% did not have any significance to the anterior tilt (p-value 0.806). A positive prone rectus test was noted in 26/64 (40%), but these patients did not have a significant anterior tilt (p-value 0.076). The posterior pelvic tilt was statistically significant (p-value 0.028) when correlated with presence of knee FFD, 25/36 (69.4%). The double pelvic bump pattern was positive in 36 patients (55.64%) and on correlating it with Hip FFD, 16% had presence of FFD and 38% had positive prone rectus test. although the cross tabulation correlation of Anterior pelvic tilt with double bump pattern with Positive prone rectus was not significant (P-value 0.99). Conclusions: The comparison of clinical parameters and 3D Gait kinematics proves that clinical signs of hamstring contractures have a significant posterior pelvic tilt; However a Hip FFD and a Rectus or iliospoas spasticity/contracture does not necessarily cause anterior tilt or double bump and hence these gait parameters should be cautiously used in decision making for the treatment of hip FFD or Rectus contracture.
