    The effects of femoral derotation osteotomy in cerebral palsy: a kinematic and kinetic study

    No full text
    We attempted to quantify the effects of isolated femoral derotation osteotomies using clinical evaluation and gait analysis (kinematics and kinetics) in patients with cerebral palsy (CP). Twelve children with CP were evaluated before and 10 months after isolated femoral derotation osteotomy, and 15 healthy children were evaluated as controls. There were significant improvements on clinical examination. A better position of the hip and ankle in the transverse plane was evident and significant changes occurred in terms of hip and ankle kinetics after surgery. Improvements in kinematics and hip and ankle power are very important biomechanically. The correction of lever arm dysfunction and more physiological hip and ankle power generation result in an improvement in terms of energy consumption, leading to a more functional and economic gait pattern

    Relationship between kinematic knee deviations and femoral anteversion in children with Cerebral Palsy

    The aim of the study was to determine the possible correlation between the degree of femoral anteversion and the quantitative data obtained by 3D Gait Analysis (GA) and then to investigate the relationship between femoral anteversion and the reduced knee flexion during swing phase in children with Cerebral Palsy. Twenty-seven diplegic children with severe rectus femoris spasticity and 20 healthy children (CG) were considered. Clinical evaluation of femoral anteversion, Duncan Ely test and Gait Analysis were performed in all patients. From Gait Analysis data some indices were identified and calculated and statistical analysis performed. Clinical evaluations made the distinction between patients with excessive femoral anteversion (Group 1) and those with normal value (Group 2). Both groups showed a blunt maximum of knee flexion in swing (KMSw), representative of rectus femoris spasticity, but two different gait strategies were found for the timing of KMSw. Group 1 exhibited a reduced KMSw value with its timing close to normal value and an excessive hip internal rotation (Mean Hip Rotation index), correlated to high femoral anteversion; Group 2 presented a limited KMSw and a significant delay of its timing, with Mean Hip Rotation index close to Control Group. No differences were found for other indices. The results demonstrated that the presence of reduced KMSw only can be directly connected to excessive femoral anteversion; the coexistence of reduced KMSw and its delayed timing reveals that the rectus femoris spasticity may be due to rectus spasticity added to an incorrect motor selective control. The results are clinically crucial for treatment strategies (derotative femoral osteotomy vs rectus transfer). </jats:p

    Language disturbances in a group of participants suffering from Duchenne muscular dystrophy: a pilot study

    No full text
    Results from several studies suggest that the process of language acquisition may be altered in patients suffering from Duchenne Muscular Dystrophy (DMD). In this study, a group of eight male DMD participants (mean age: 16; SD 4.7) underwent an extensive neuropsychological and language assessment. Furthermore, they performed a discourse production task. Results evidenced mild mental retardation associated with a specific deficit in Verbal rather than Performance IQ. At the linguistic assessment, seven out of eight participants showed moderate to severe difficulties on oral language processing with particularly impaired morphosyntactic competence
