Treatment of neuromuscular dysfunctions of the musculoskeletal system and disorders of accommodation

 

(57) Abstract:

The invention relates to medicine and can be used for functional correction of functional disorders of children with congenital and acquired pathology of locomotor apparatus, for posture correction and treatment of early stages of scoliosis, as well as in ophthalmology for the treatment of amblyopia. To improve the efficiency of the correction functions in younger children (6-7 years old) spend the correction sessions in which the patient is shown the subject image in the form of computer games, record bioelectric activity of the patient, and measure its integral envelope, and depending on the amplitude envelope, the patient has the ability to control a computer game. If bioelectric signal is less than the threshold value, the computer game stops, and control the game with the help of the manipulator is impossible. To run computer games, the patient will need to produce an action directed at changing the bioelectric activity, i.e., to strain the attention in vision correction, or to produce muscle contraction with movement correction, or symmetrically to stretch the muscles on both sides of the spine in the correction of the OS is AI physiological functions in children with congenital and acquired pathology of the musculoskeletal system, for posture correction and treatment of the initial stages of scoliotic illness, as well as in ophthalmology for the treatment of amblyopia.

The number of known methods of functional correction relating to how biofeedback feedback (source). The use of these methods requires the presence of an unambiguous Association between the running patient action (movement, focus, etc. and the inclusion of feedback signals.

It is also known that as feedback signals are commonly used indicator lights, audible signals, or skin irritation. However, in cases of pathological conditions in children of early age or in children with a defect of the intellect functional correction method biofeedback is difficult due to the fact that the patient is unable to establish an unambiguous logical dependencies between the services provided by action and artificial feedback signal. This is due to the fact that a child under the age of 7 years, as a rule, does not understand the job, tired and quickly loses interest in the correction procedure, due to the lack of motivation to act on the feedback signal (sound, light stain, etc.,), s queue, leads to less effective treatment of several diseases, such as cerebral palsy, ERB's palsy, impaired posture, amblyopia and other, for which treatment is essential as early as possible correction in childhood.

The closest major signs to the present invention is a method of amblyopia in children, which is to conduct vision correction sessions in which the patient close your eyes, and produce light irritation of the patient's eyes, by the presentation of the subject image. At the same time as an informative indicator of changes in the functional state of the brain using electroencephalography (EEG). As the subject image, the patient is shown the slide, the brightness of which varies depending on the level of activation of the brain, what is judged by EEG. While the measured integral envelope EEG amplitude is compared with the threshold value set by the doctor. If the amplitude envelope of the EEG is greater than the threshold value, the image brightness is low, and if less than the threshold value, the brightness of the subject image is high. The threshold level in the known method is a doctor with POM what I amplitude envelope EEG was below the level set threshold.

It should be emphasized that, as in most cases the use of biofeedback, in this method of vision correction is a leading factor in the high motivation of the child by the correction procedure. This allows to overcome certain load, inevitably associated with correction of pathological conditions. For this reason, this method has limited application. This is due primarily to the fact that children under the age of 6-7 years can not establish a connection between the change in the brightness of the subject image and their own state ( and action that they will make. Therefore, the child quickly loses interest in the procedure, tires, causing negative emotions, against which the correction of amblyopia impossible.

The aim of the invention is more effective correction of pathological conditions in children of early age.

This is achieved by the fact that the correction method of the previously mentioned pathological conditions in children, consisting in the carrying out of sessions of correction not less than two times a week for 15-20 minutes each, a total of 10-20, the patient is shown the subject image; register bioelectric activechinese compared with a threshold bioelectric activity control of the subject image. The distinctive feature is that as the subject image using graphics, computer games, control start and stop of the subject image on the computer screen is based on the ratio of bioelectric activity recorded from the patient and the prescribed threshold, with the threshold of bioelectric activity is chosen so that the amplitude envelope exceeded the threshold for 60% of the time of presentation of the subject image.

Graphics computer games for young children at the time of correction sessions, encourages him to do the job, due to the higher interest of the child to the colorful dynamic situational computer game, compared to the simple light or sound feedback signals. In turn, a more effective source of motivation causes much more striking Association between feedback signals (start and stop of the game) and the underlying behavior of the patient (the focus or the voltage of a particular group of muscles). This leads to a more effective correction of the functional state of the patient.

The proposed method is as Obernai games. The game program which is entered into the computer, selected on the basis of patient's age, his intelligence and psycho-emotional state.

Bioelectric activity is recorded by a sensor, while as an informative indicator of changes in the functional state of use, depending on the disease, the electroencephalogram (EEG) or electromyogram (EMG).

Then measure the integral envelope EEG (EMG), and comparing the amplitude with a threshold value.

The threshold value of bioelectric activity is chosen so that the amplitude envelope of the EEG (EMG) exceeded the threshold for 60% of the time of presentation of the subject image. This threshold is set by the doctor after not less than 1 min envelope analysis EEG or on the basis of the correct execution of patient-motor tasks (EMG). If the time of presentation of the subject image is less than 50%, the patient loses interest in the job because of the frequent shutdown of the game. At the time of presentation, more than 70% lack of motivation to perform the necessary training actions, because even with minimal effort on the part of the patient, the game rarely stops.

the Device has connected in series sensor 1, the amplifier 2, block 3 rectification and filtering, and the comparator 4, the second input is connected to the midpoint of the potentiometer 5. The output of comparator 4 is connected to the input of block 6 of the agreement, the output of which is connected to the input of the START of the computer 7. The management of the movement of the subject image on the computer screen by the patient by means of a manipulator 8.

During the session, the adjustment of the sensor 1 register the electroencephalogram (or electromyogram), this signal is amplified in block 2, block 3 of the EEG signal (EMG) is converted into an envelope EEG (EMG) by rectification and low-pass filtering with a time constant of 0.5 C. the Voltage output unit 3, is directly proportional to the signal bioelectric activity, served on the direct input of the comparator 4, to the inverting input of which is supplied a voltage from the potentiometer 5, corresponding to the threshold value of bioelectric activity.

The matching unit 6 causes the logical output signal of the comparator 4 in accordance with the logic circuits of a standard computer input 7. If the signal from the sensor 1 exceeds a set threshold, the computer is in run mode, and the patient who is, the computer game is stopped and the control IG - Roy manipulator impossible. To run computer games, the patient will need to produce an action directed at changing the bi - elektricheskoi activity, i.e., to strain the attention in vision correction or to produce muscle contraction with movement correction, or the balanced - ranks strain the back muscles on both sides of the spine in the correction of posture.

To use the signals from the two sensors (in the case of cor - correction of posture) in block 6 approval of an additional entrance. This block is implemented as a combinational logic circuit on the element base standard

Treatment of neuromuscular dysfunctions of the musculoskeletal system and disorders of accommodation in children, including registration of bioelectric activity, the definition of its amplitude envelope and the values of the values obtained for the determination of threshold signal biofeedback in the management of the subject image, the two or more sessions per week for 15-20 min at treatment 10-20 procedures, characterized in that the threshold value of the count signal so that the led is este subject image using graphics, computer games, and control of the image is carried out by stopping the game by reducing the amplitude of the bioelectric activity below a certain threshold.
