Project summary

Within the framework of the project the device for checking time and strength characteristics of the motor activity of hand and providing examinee information on these parameters as a feedback from a puppet that reflects the movements of the patient will be elaborated. The working out of the electronics to check parameters of the motor activity of hand (programs, sets of meters for measuring muscle strength and other tools) is planned.

On the basis of the this device, differentiated method for recovery of voluntary finger movements in patients with affection of the central nervous system will be devised. The patient watching the puppet movements and obtaining visual information on the character of his/her finger movements will be able to improve control over the motor activity, and restore the mechanisms of voluntary movement regulation. This is more important on rehabilitation patients with impaired sensibility and apraxia (impairment of ability to execute movements without muscular paralysis).

The distinctive feature of the method will be its playing format, making the medical rehabilitation of adults with emotional disturbances and also children with disorder in psychophysical growth much easier, as the work done with a puppet highly justifies patients to keep on training.

The device will be elaborated in compliance with scientific and practical data on rehabilitation of such diseases as infantile cerebral paralysis, severe stroke, craniocerebral injuries, peripheral nervous system traumas, etc., which have been acquired by the workers of Nizhny Novgorod State Medical Academy and Nizhny Novgorod Institute for Education Development.

After bench test of the working prototype of the training model and the trial of the new correction technique in neurorehabilitation groups of NNSMA and NIDE the follow-on training models will be made to fully satisfy the needs in rehabilitation treatment of various forms of superior limb affection.

The results of research will be published and reported at international conferences in Russia and abroad. Once the project is completed, the new device and the finger fine motility development technique will be recommended for wide use in rehabilitation of patients with impaired hand functions. The great experience and high qualification of the workers of the Federal Nuclear Center, Nizhny Novgorod State Medical Academy, and Nizhny Novgorod Institute for Education Development engaged for this task, as well as scientific-engineering capabilities of these institutions guarantee successful project implementation.

Project objectives:

  1. Elaborate a biofeedback (BF) device for rehabilitation and better motor activity of hand to allow more effective rehabilitation procedures in real time for patients with affection of the central nervous system.
  2. Devise an electronic system for estimating temporary and strength characteristics of differentiated finger movements.
  3. Create a unique puppet method based on the device to be developed.
  4. Performance evaluation of the devised method in rehabilitation of patients with the pathology of the central nervous system, as well as in rehabilitation of children with various psychophysical impairments.
  5. Reduce the terms of rehabilitation of the patients with impaired movement and super limb coordination disorders. Improve rehabilitation quality, particularly in pediatric practice by using a puppet. Initiate a positive psychological situation while working with children.
  6. Work out differentiated methods of finger movements in various pathogenetic cases of impaired hand functions, as well as in children with various psychophysical traits.
  7. Improve the versatility of the biofeedback device while working with children with emotional problems through the synergy of psychotherapeutic and functional methods.
  8. Saving of expenses for drugs and less likelihood of the side effects due to drug treatment.
