Abstract

We evaluated the therapeutic effects of anti-gravity locomotor treadmill (AlterG) training on postural stability in children with Cerebral Palsy (CP) and spasticity, particularly in the lower extremity. AlterG can facilitate walking by reducing the weight of CP children by up to 80%; it can also help subjects maintain an appropriate posture during the locomotor AlterG training. Thus, we hypothesized that AlterG training, for a sufficient period of time, has a potential to produce cerebellum neuroplasticity, and consequently result in an effective permanent postural stability. AlterG training was given for 45 minutes, three times a week for two months. Postural balance was evaluated using posturography. The parameters of the Romberg based posturography were extracted to quantify the Center of Balance (CoP). The neuroplasticity of Cerebellum was evaluated using a Diffusion Tensor Imaging (DTI). The evaluations were done pre- and post-training. The Fractional Anisotropy (FA) feature was used for quantifying structural changes in the cerebellum. The results showed that AlterG training resulted in an increase in average FA value of the cerebellum white matter following the training. The results of the posturography evaluations showed a consistent improvement in postural stability. These results were consistent in all subjects. Our findings indicated that the improvement in the posture was accompanied with the enhancement of the cerebellum white matter structure. The clinical implication is that AlterG training can be considered a therapeutic tool for an effective and permanent improvement of postural stability in CP children.
