Abstract: В статье разработана методика оценки погрешностей подсистем S-контроля и R-контроля, как составных частей опорно-двигательной системы человека. Разработан критерий максимальной правдоподобности для оценки точности измерений параметров опорно- двигательной системы человека.
Description: In this paper the technique of errors estimation of S-and R-control subsystems as parts of the human musculoskeletal system is developed. Realistic criterion for assessing the measurements accuracy of the human musculoskeletal system is developed. To determine the effectiveness of drugs and medical interventions during rehabilitation of musculoskeletal and motor functions pathology after human injuries, the overall condition of the human must be considered (temperature, pulse, blood pressure), which are dependent on the biorhythms state. It is also important to determine the optimal conditions for measurements in order to obtain maximum likelihood results. As an objective statistically reliable assessment of traumatized human state, mathematical expectation  and dispersion  are suggested, obtained on the measurements results basis made in certain conditions. The histograms analysis shows that if we increase the number of observations, and the interval tends to zero, the histogram in the limit becomes a continuous characteristic of the distribution of errors. Sufficient conditions for the error components smallness were defined. To estimate the human musculoskeletal system measurement errors is necessary to evaluate the effectiveness of the treatment effects of traumatism through information-measuring system of human motor functions, to determine the criteria that characterize the degree of closeness of the consequences of traumatism to safe (desired)situation. Evaluating the effectiveness of the treatment effects of traumatism by the operation of IMS DPF can be made by characterizing the degree of closeness of the consequences of traumatism to safe (desired)situation. In IIS DPF it is necessary to control two independent variables. These variables are controlled by the amount of displacement of each vertebra relative to the reference value and the load level on the lower limbs (resultant force).
