In some applications it is important to detect the QRS complex in the ECG waveform with possibly low time delay. Traditional software detectors of the QRS complex implement algorithms usually based on cascades of digital filters that introduce delays up to parts of a second. On the other hand, hardware QRS detectors fulfil the low delay requirements, but(More)
Spasticity is a common impairment that interferes with motor function (particularly gait pattern) in children with cerebral palsy (CP). Gait analysis and clinical measurements are equally important in evaluating and treating gait disorders in children with CP. This study aimed to explore the relationship between the spasticity of lower extremity muscles and(More)
The paper proposes a new approach to the analysis of the human postural stability. In this method, based on parametric representation of the center of pressure (COP) trajectory, a new one-dimensional signal is calculated. The use of the signal results in a reduction of the problem complexity and makes possible defining of new parameters that describe(More)
Development of a reliable and objective test of spasticity is important for assessment and treatment of children with cerebral palsy. The pendulum test has been reported to yield reliable measurements of spasticity and to be sensitive to variations in spasticity in these children. However, the relationship between the pendulum test scores and other(More)
PURPOSE Presentation of the results of clinical study on new supplementary method applied in the physical rehabilitation of patients who underwent total hip arthroplasty. The standard rehabilitation program was supplemented with the lower limb loading symmetry training based on the follow-up posturography with an adaptively modified visual biofeedback,(More)
BACKGROUND We analyzed assessment of equilibrium system efficiency versus organic test performance and dependence on functional aspect of cognitive and psychomotor functions. MATERIAL/METHODS A population of 250 persons from 15 to 65 years of age was examined. Measurements of the sense of balance were carried out by means of computer posturograph. Three(More)
