Twenty-nine children with cerebral palsy and triceps surae hypoextensibility were divided into 2 groups. In group I trophic regulation of the muscle was defective and in group II it was normal. Torque values were plotted against tibiocalcanean angles before and after treatment, which consisted of muscle lengthening by successive plaster casting or of(More)
This work is a critical analysis of the term "flexibility of scoliosis." The authors demonstrate that this measure includes two very different and noncorrelated phenomena: the collapse and the reducibility of the structural curve. In 228 paralytic curves, these two phenomena were quantified and correlated with different parameters of scoliosis: sex, stage(More)
The oral stage of swallowing was studied in two groups of 10 cerebral-palsied (CP) children (one drooled and the other did not), and 10 normal children, aged six to 14 years. Small amounts of liquid (0.5 to 1mL) were placed under the tongue or behind the lower lip and intra-oral pressure was measured during the suction and propulsion stages. The CP children(More)
The passive extension of relaxed hip adductor muscles was measured in 20 normal children and 10 children (aged nine to 13 years) with cerebral palsy (CP) by a method that could distinguish between shortening of the muscle body and tendon. No muscle-body contracture occurred in the children with CP during treatment (physiotherapy plus moderate stretching on(More)
The extent to which treatment of passive muscle contracture could be minimised without loss of efficiency was studied. Soleus muscle contracture was measured by the difference between the ankle angles at which minimal and maximal resistance occurred during slow dorsiflexion of the ankle. This examination was done twice, at the beginning and end of a(More)
1. The apparatus and method described give the relationship of triceps surae torque to the absolute tibio-tarsal angle. Data of the anatomy of the foot and the axis of the ankle are taken into consideration. They make complementary measurements necessary, which in certain cases enable the angle recorded by the apparatus to be corrected so as to obtain the(More)
The study was designed to provide a quantitative analysis of toe-walking in children with cerebral palsy (CP). The total internal moment developed about the ankle joint during locomotion and the passive component of this internal moment were measured. The contributions of the active and passive components were expressed as the ratio (R) between the passive(More)
The present study gives the results of a comparison of the recorded and true tibia-calcaneal angles in 17 normal subjects and in 14 patients with abnormally hypoextensible non contracting triceps. 1. For a minimal passive torque, the difference between true and recorded angles varied considerably from one individual to another. The means and ranges for the(More)
Since poor control of muscle contractions in cerebral palsy may be due partly to defective processing of data originating from muscle, the need arose for a test as uncontaminated as possible by other afferent effects. For 18 normal children, vibration of the brachial biceps tendon always gave the illusion of elbow extension; when the triceps was vibrated(More)
A decrease in sarcomere number and hypoextensibility of ankle extensors was observed in certain children with congenital cerebral lesions. This phenomenon was reproducible and reversible in normal animals, i.e. trophic regulation adapted the muscle to the imposed length. The form of the torque-ankle angle curve was studied in 30 children. Its modification(More)
