An important part of any rehabilitation procedure is the patient's ability to control exercising accuracy in the real time. The doctor or training specialist provides feedback in the traditional mode of such exercises. In this work we suggest using smartphone MEMS sensors (which function for fixation of motion pattern) as the feedback. The main goal is comparing the acquired motion pattern with its model sample. DWT algorithm was chosen as the estimating method of similarity measure of the two patterns. Determination of parameters, which define exercising quality, was based on quantitative characteristics computation of each iteration of motion: accuracy, synchronicity, amplitude, number of repetitions.
