«Kolibri» biofeedback system for psycho-emotional correction

2. The specialist flexibly adjusts the training parameters individually for each patient, taking into account the current functional capabilities and features. Options for setting up parameters and training modalities are detailed in the program instructions.

3. For convenient operation of the Kolibri BOS system, two monitors are required:

• basic monitor – for the examining physician (program control, selection of initial parameters, making changes to the training mode during work with the patient);
• additional monitor – for the patient (displaying the game to visualize the patient’s activity and provide visual feedback).

4. To conduct training, the specialist uses pre-set courses. The course consists of several sessions (usually about ten), each session consists of one or more trainings. The software includes the following courses:

• psycho-emotional correction (relaxation);
• relaxation with elements of concentration;
• balanced concentration/relaxation;
• concentration with elements of relaxation;
• psychologopedic correction (concentration).

5. The software automatically sets boundaries for the area of successful attempts for each course, which allows monitoring the patient’s success in completing the exercises.

6. After the training starts, the sensors begin to record, amplify, digitize the received signal and transmit data (via Bluetooth protocol LE) into a program installed on a specialist’s computer or laptop.

7. Specialized software processes the received data and displays it as:

• initial signals – on the specialist's screen;
• game scenario – on an additional monitor for the patient.

8. The Kolibri BFB system has a mechanism for checking contact with skin. Skin contact testing is performed for each channel separately.

9. The system includes a large number of games (more than 15 game scenarios), allowing biofeedback training to be conducted in an interactive form, facilitating the routine training process, which is especially important for children. Games are a mechanism for assessing feedback for the subject: successful achievement of the game's goal reflects the correctness of the training.

The choice of game is determined by the number of resulting channels, the individual characteristics of each patient (taking into account the existing pathology and the physician's recommendations).

System benefits

• the miniature size of the sensors provides flexibility and comfort in the specialist’s work with the patient;
• the wireless design of the complex minimizes artifacts and ensures reliable and high-quality signal recording;
• the received signal is transmitted to multifunctional and convenient software installed on a computer or laptop;
• the data obtained allow the specialist to objectively assess the patient’s current capabilities, select a treatment protocol based on individual characteristics, adjust the parameters of training with biofeedback, dose and control the load both during each session and throughout the entire course of treatment;
• special sensors allow to track the state and changes in physiological processes that are difficult to feel and control under normal conditions;
• for maximum rehabilitation effectiveness, game motivation technology is used;
• after each training, a report is generated that clearly and objectively reflects the effectiveness of the work done;
• the possibility of conducting multimodal trainings, the configuration of which allows to use any combination of EEG, ECG, EMG, abduction angle and respiration signals;
• the presence of a database of pre-installed courses developed by practicing specialists: the system allows selecting a course in accordance with the patient’s medical history and conducting training automatically. Pre-created training templates allow for rehabilitation training sessions in conditions of a large flow of patients and serve as an aid to a specialist (physician's assistant, nurse, exercise therapy instructor). The structure of the courses is designed to gradually increase the complexity of tasks, which allows to gradually increase the result obtained;
• the system allows to create and save new training templates for different rehabilitation tasks.

System and software capabilities

Key software functions:

• the program allows to work in dual monitor mode: the software functions are automatically distributed between the specialist's monitor and the patient's monitor, which allows the latter not to be distracted from the game situation by physiological indicators necessary exclusively for the professional analysis;
• the ability to customize the number of channels used in a training session (up to 4 simultaneously);
• the presence of a library of pre-installed courses and trainings developed by practicing specialists and intended for various rehabilitation purposes (psycho-emotional correction, restoration of muscle motor activity, etc.);
• development of your own unique methods (training courses) aimed at correcting the necessary parameters, with their subsequent saving in the user library;
• the ability to configure monitoring channels that are not involved in the game process;
• the possibility of conducting multimodal training sessions that enable to work simultaneously with several different types of signals;
• adaptation to a specific user taking into account individual characteristics (the presence of an expert adaptive system in the program for determining the patient’s capabilities before the start of training);
• the presence of a variety of game situations (more than 15 games) that attract the user and make the rehabilitation process more visual and engaging;
• the ability to upload your own (user-defined) templates (images, texts, audio and video files) required to run games;
• allows to pause the gameplay (if necessary) during the training (pause mode in games);
• provides the ability to manually (directly during training) and automatically (contains a built-in editor for channel-by-channel creation of arbitrary laws) control the boundaries of the area of successful attempts;
• the ability to adjust the depth of feedback (sensitivity of the program's response time to changes in the physiological signal);
• allows to set the time for automatic completion of training (end of training timer);
• during training, the program displays the initial physiological signal being recorded and the trend of attempts on the specialist’s screen;
• calculation of EEG signal spectrum in real time;
• calculation of heart rate parameters and stress index via the ECG channel;
• analysis of respiratory rate and respiratory phase;
• generates an advanced report on each training session conducted;
• visually displays the dynamics of indicators within the training course, which enables to evaluate the overall effectiveness of rehabilitation;
• checking the quality of contact between the electrodes and skin during training (indication of electrode detachment);
• contains a built-in database of standard templates and phrases for filling in the fields of the reporting form, with the opportunity to add, save, edit and delete your own templates and phrases.

Database functionality:

• the user-friendly and intuitive database interface allows to quickly fill in information about the patients during their registration in the electronic card file;
• mechanisms for sorting the patient list by criteria (alphabetical order, gender, age, registration date and last examination date) and quick search for a patient from the list by several letters of the full name;
• wide opportunities for remote and distant analysis of training results by specialists via cloud storage or network drive: completed training sessions are automatically uploaded to any convenient cloud service, which provides access to the results from anywhere in the world;
• the ability to export the reporting form to Microsoft Office Word and PDF;
• import/export of completed training sessions;
• high level of security for the data stored – encryption of results, backup and restoration of the database from a backup copy;
• the ability to create databases individually for each user (specialist).
