INTRODUCTION Knee flexion is one of the main problems of the lower extremities in cerebral palsy patients. Many operative procedures are recommended for contractures of the knee in cerebral palsy patients. We performed simple operation and analyzed the results after operative treatment with nine years follow up. METHOD 85 patients with spastic cerebral palsy were treated in period 2001 - 2010...

Crouch gait deformity is common in children with cerebral palsy and often is associated with patella alta. Patellar tendon advancement typically is used to correct patella alta and restore normal knee mechanics. The purpose of this study was to determine the mechanical strength of surgical constructs used for fixation during patellar advancement procedures. This study used a cadaveric model to ...

In this paper we replace the static meaning representation language in the LFG linear logic based glue language semantics approach Dalrymple et al., 1993b; Dalrymple et al., 1993a; Dalrymple et al., 1995b; Dalrymple et al., 1996] with a dynamic meaning language Muskens, 1994b; Muskens, 1994a]. This move extends the original approach to discourse phenomena and can be combined with the approach t...

objectives: deterioration in postural control mechanisms is termed postural instability and results increased postural sway and many laboratory techniques and instruments are characterized by a wide range of neurological signs and symptoms to the medical management. thus the current study designed to assess the reliability of commonly used clinical measures of balance and determined normal valu...

Motivated by developments on differential Lyapunov functions for contraction analysis in Forni, Sepulchre (2012) we propose a definition of differential passivity, based on the geometric framework of the prolongation of a nonlinear system in Crouch, van der Schaft (1987). We explore the ramifications of this definition and its potential uses.
