Abstract
Introduction: Dysfunctional postural control is one of the key problems in children with cerebral palsy (CP) which interfere with the activities of daily life and have been suggested to be a major component of gait disorders in CP. The purpose of this study was to investigate the relationship between isokinetic strength of knee with postural balance control in patients with different types of CP and vertical jump, as a tool for dynamic evaluation of power.
Methods: 23 patients with spactic diplegia participated and gave their informed consent prior to participation. Standing posture balance and counter-movement jump (CMJ) measurements were performed with a force platform. The isokinetic evaluation was recorded with an isokinetic dynamometer
Results: Statistical analysis found significant linear correlations (p <.000 to p <.034) between peak torque of flexors and extensors at all speeds and the distance covered by the CoP. Correlations have been found between the isokinetic parameters and the dispersion/area covered of the CoP. Significant relationship (p <.000 to p <.002) have been found between the CMJ and the peak-torque of the flexors and extensors of the knee in both legs (p <.001 - p < .019).
Discussion and conclusions: Result showed a strong correlation between isokinetic and accelerated movement. Muscle strength in accelerated conditions has been shown to be a key factor in the maintenance of balance during upright standing position in this population. Young adults with cerebral palsy might benefit from therapies involving lower limb strengthening. Isokinetics seems to be very useful proceeding for evaluation, rehabilitation and training of young adults with cerebral palsy.
