Justification of the personalizied approach to application of EMG biofeedback in case of cerebral palsy

The purpose of the research was justification of feasibility of biofeedback technology for children with spastic diplegia and hemiparetic cerebral palsy (CP), and selection of optimum methods of a game-based electromyography training (EMG-training) for clinical forms of paralysis. Materials and methods. The research covered one child aged 7 suffering from spastic cerebral palsy, and the second child aged 12 suffering from hemiparetic cerebral palsy. The research included records of background indicators of children muscle activity with «BOS-LAB professional +» hardware-software system. The following research methods were used: analysis of profiled scientific and methodical literature; assessment of motor functions status and its alterations with «Gross Motor Function Measure – 88» (GMFM-88) method of quantitative assessment; game-based EMG-training with «BOS-LAB professional +» hardware-software system; assessment of vestibular stability («Stabilan-01-2» stabilizer); methods of mathematical data processing. Results. Selection and application of individual game-based EMG-trainings together with remedial exercises for the child suffering from hemiparetic cerebral palsy resulted in reduction of excessively high muscle tone of top and lower extremities that contributes to normalization of motor functions and also activates processes of motor adaptation to the environment. The similar effect was achieved when using EMG-trainings for correction of excessively high muscle tone of the child suffering from spastic cerebral palsy. The authors had another approach to a technique of muscle tone normalization for the child suffering from spastic cerebral palsy, which differs from hemiparetic form: muscle tone of a knee joint flexor (biceps femoris) has been lowered, and the tone of rectus femoris has been increased that subsequently should improve static and dynamic indicators of the child suffering from spastic cerebral palsy. Conclusion. Electromyogram trainings can be applied in the comprehensive habilitation process in order to adapt children with cerebral palsy to environmental conditions.
