FRANCIULLI, Patrícia Martins et al. Isokinetic analysis of the elbow joint in children with cerebral palsy. Motriz: rev. educ. fis. [online]. 2012, vol.18, n.1, pp.55-62. ISSN 1980-6574. http://dx.doi.org/10.1590/S1980-65742012000100006.
The joint torque is an important variable related to children with cerebral palsy. The present study analyzed kinetic parameters during elbow flexion and extension movements in healthy and cerebral palsy children. Ten healthy and 10 cerebral palsy children participated of the study. An isokinetic dynamometer was used to measure the elbow mean peak torque, mean angle peak torque, coefficient of variation and acceleration during flexion and extension movements at different angular speeds. The mean peak torque on extension movement in healthy children group was significant higher compared to the cerebral palsy group. The coefficient of variation on both flexion and extension movements was significantly higher in cerebral palsy group. However there were significantly difference on both groups compared the lowest and highest velocities. Although the results showed no difference in flexor peak torque, the acceleration is significantly lower in lowest and highest angular velocity.
