    Severe crouch gait in the sagittal gait patterns of spastic diplegic cerebral palsy: the impact of single event multilevel surgery
    Rodda, Jillian Maree ( 2005)
    The purpose of this thesis was to study the outcome of Single Event Multilevel Surgery (SEMLS) on the gait pattern known as crouch gait in children with spastic diplegic cerebral palsy. The term “crouch gait” in the literature has been defined by many authors to mean a flexed knee coupled with many different combinations of posture at the ankle. Consequently it was necessary to provide a robust definition of crouch gait before the outcome study could proceed. Crouch gait was defined in the context of a classification of sagittal gait patterns in spastic diplegia. In the cross-sectional study on the classification of sagittal gait patterns, 187 children with spastic diplegia were categorised according to visual recognition of their gait pattern and sagittal plane kinematic data. Six gait patterns in spastic diplegia were identified, one of which was crouch gait. A pattern of increasing age, severity and biomechanical incompetency in maintaining an extended posture was seen across the gait patterns and crouch gait appeared to be the “end” gait pattern. A longitudinal study documented how the identified gait patterns evolved over time. Thirty-four children were followed for more than one year and the results indicated that the stability of the gait pattern was variable. The reliability of the classification was found to be acceptable. (For complete abstract open document)
