The balance system “Biokinekt” is designed for the diagnosis of balance disorders, objective evaluation of the treatment efficacy and the balance of functional recovery by means of the biofeedback method (BFB).
Stabilometrics, is a standardized method for postural disorders diagnostics, and is included in the orders, protocols and standards of care. The order of the Ministry of Healthcare of the Russian Federation of 29.12.12.#1705 n “On the Medical Rehabilitation Management”.
The method becomes increasingly important in widely differing areas of clinical medicine allowing Healthcare Professionals to assess the efficiency of the whole balance system and perform topical and
nosological diagnostics of the patient’s balance system disorders.
In neurological practice the stabilometrics application range comprises such areas as cerebrovascular pathology (diagnostics and rehabilitation of patients with earlier stroke consequences, vascular encephalopathies etc.), degenerative-dystrophic diseases of the central and peripheral nervous system (Parkinson’s disease,various types of ataxia, osteochondrosis), myodystrophies, CP, brain injury etc.
In traumatology and orthopedicsstabilometrics allows the detection of the asymmetries of the locomotor system, anomaly of joints and column, perform posture correction and correctly to select orthoses and prostheses. Currently,stabilometrics is the only objective tool for postural function evaluation.
The method is widely used in sports medicine for diagnostics and rehabilitation allowing the study of the balance function of sportspeople, their static and dynamical stability (SDS), exercise training quality control and assess their exercise tolerance.
In stomatology the installation of dental prosthesis, brackets and other interventions in the maxillofacial apparatus can affect the patient’s balance function. Stabilometry is used to monitor the success of interventions conducted (including the absence of any impairment of the balance control).
By means of stabilometry in otorhinolaryngology the vestibular system functions are studied, in ophthalmology – this allows the assessment of the functional results of vision correction possible. In addition, a pharmacological drug effects assessment is performed, thereby revealing in addictology, how alcoholic Intoxication severity is. In Physiotherapy stabilometry makes it possible to assess the treatment efficacy.
Stabilometry and 3D Stabilometry
The classical stabilometrics method (which literally means stability measurement), is an objective estimation method of posturology function, which has been known since the 70s. In the 80s with the appearance of personal computers, computer analysis and signal visualization methods, stabilometric platforms became widely used in medical practice which allowed recording the pressure centre projections on the bearing area in 2 coordinates (2D Stabilometry). Such measurements can hugely restrict the objective evaluation of posturological functions.
But medical progress does not stand still! The “Biokinekt” balance system is accomplishing three-dimensional stabilometry 3D linked with the classical methods of 2D stabilometry. Using biomechanical sensors together with a stabilometric platform allows recording the fluctuations of the common pressure centre (CPC) in sagittal and frontal plane as well as the motions of any
body segments in 3 directions (forward – backward, right – left, up-down), assessing segment rotations, tremor and myoelectrical activity.
The total information on fluctuations of CPC and fluctuations of separate body segments allows the medical practitioner to accurately determine the pathological process level. The capability to record fluctuations in the whole frequency range, including high frequencies, significantly increases the methods sensitivity, which allows detecting even insignificant increases of muscle tone. Combined use of the stabilometric platform with biomechanical sensors makes it possible to study infants thereby facilitating early prenosological diagnostics whereas using only a stabilometric platform has age limit to 4-5 years.
Assessing tremors is a substantial advantage to the physician. Tremorsare frequently reported by neurological patients. Practice motion syndrome can be present in many diseases as well as in healthy people. Sensors “Bisens” allows medical professionals to perform a tremor analysis and evaluate its frequency, amplitude and spectral characteristics which significantly lightens differential diagnostics of diseases accompanied by shaking (essential tremor, Parkinson’s disease).
Synchronous myographic examination of the lower limb muscles or trunk during stabilogram recording makes it possible to define the internal strategy for maintaining balance in the main posture.
BFB or Biofeedback – is a method of medical rehabilitation comprising a package of diagnostic, treatment and preventive procedures whilstthe patient continuously receives information about the state of his physiological processes in a form easy for a lay persons level of understanding.
The output of biofeedback canbe compared with a “physiological mirror”. The task of the procedure – to teach This involves the patient receiving information in real-time to adapt and control and thereby change his physiological parameters.
The “Biokinekt” balance system makes it possible to perform a highly efficient BFB method of rehabilitation inpatients diagnosed with locomotor system and postural disorders. Exciting play media with a possibility of “particiapting” in a virtual reality increase a patient’s motivation and consequently, the treatment process becomes much more pleasant and interesting.
When conducting the BFB procedure on the “Biokinekt” balance system the following physiological parameters are employed:
• Support reaction (per CPC plane coordinates)
• Movements in segments
• Joints and segments rotations
• Tremor monitoring
• Myoelectrical activity.
The Stabilometry-Neurocor’s computer software has a customized interface Wizard to help the doctor quickly and easily to adjust the parameters of BFB action for a specific patient with the necessary amplitude and sensitivity. The standard software bundle comes complete with a set of a various playful interactive scenarios including “Target”, “Boat”, “Snowboarder”, “Delta Plane”, “Rally”, “Labyrinth”, “Paper Plane”, “Rocket”, “Forest Walk”, “Virtual Joystick”.
These interactive scenarios have various tuned techniques that allow a patient to train their individual centre of gravity whilst retaining their centre of gravity so as to perform a temporary fixing of theircentre of gravity in a certain place, control muscle tone and train angle contractures in joints etc.
As BFB visualization tools in the Trust-M Stabilometry platform an LCD-Panel, projection screen, virtual reality glasses suitable for stereo image.
One of the features of the Trust-M Stabilometry Platform is the virtual reality module (VR) which allows the physician to create unique diagnostics tests and BFB rehabilitation methods. The use of the technology significantly expands the possibilities for conducting clinical tests of sensor interaction in different virtually simulated conditions for determining the type and the degree of balance disorder.
A special test of Sensory Interaction was developed for the “Trust-M” Stabilometry Platform in virtual reality environment. Using the test it is possible to evaluate the condition/stability of the somatosensory system in the presence of a disturbing action on the visual perceptual system.
The test is based upon the recording and analysis of a patient’s postural fluctuations in the presence of preprogrammed sensory loads (optokinetic testing in virtual environment, blurred image, receding room, “sea rolling effect”).
For rehabilitation methods, the BFB virtual reality technology allows creating exiting playful and interactive environments thereby enhancing a patient’s motivation and transforming training into an amusing and enjoyable time.
Virtual reality has several advantages in treatment of patients requiring physical rehabilitation. The method is particularly useful for individuals with disabilities. Spine injured patients in wheelchairs can again feel as if they are standing on their feet.
Postural tests and parameters
The balance system “Bioki9nekt” Stabilometry allows to perform a full-fledged posturological study in accordance with international standards with calculation of the main diagnostic criteria:
- Average velocity of the centre of pressure travel;
- statokinesiogram area;
- mid position of the centre of pressure in X and Y direction;
- maximum values of the pressure centre fluctuations amplitude along the axis;
- standard quadratic deviation of the pressure centre mid position along the axis;
- basic frequency of pressure centre fluctuations along the axis;
- level of fluctuation spectrum power baseband along the axis;
- statokinesiogram length;
- mean direction of the centre of pressure fluctuations;
- Romberg ratio;
- energy expenditure ratio;
- evaluation of the effectiveness of the specified action in BFB tests
Thereby the quality of the posturology study results, the possibility to easily use, compare data received, compare them with research and practice literature and other sources.
The platform supports accepted research methods of the main posture balance when changing different external conditions. The following tests are used most frequently in medical practice:
• Romberg test, the point of which is that during studies,a visual analyzer impact is excluded; the upright position is kept only thanks to proprioception;
• Optokinetic testing allows the evaluationof the reaction of the sensorimotor system on a visual stimulation, for example, on black and white moving bands;
• Stability limit test consists of a series of consecutive changes of a patient’s body positions and allowing to vividly evaluate the travels of the centre of pressure in the maximum possible leaning either left-right and forward - back when patient is capable of keeping their balance;
• sensory-vestibular test reflects on a stabilogram the response of the balance control system to a provocative action of head rotation to either the left and right.
