[Purpose] Low back pain is a pervasive problem in modern societies. Physical rehabilitation in treatment of low back pain should reduce pain, muscle tension and restore spine stability and balance. The INFINITY® rehabilitation method that is based on a figure of eight movement pattern was proved to be effective in low back pain treatment. The aim of the paper is to estimate the effect of a figu...

Furstenberg in his paper Fu71] considered the Brownian motion on a Rie-mannian symmetric space S and proved that if G is a lattice in the corresponding semi-simple Lie group, then for any point o 2 S there exists a probability measure on G such that the harmonic measure o of the point o on the Furstenberg boundary of the space S is-stationary, i.e., o = P g (g)g o. It implies that for any bound...

Here we report a new motion illusion where the prevailing motion direction is strongly influenced by the relative phase of the harmonic components of the stimulus. The basic stimulus is the sum of three sinusoidal contrast-reversing gratings: the first, the third, and the fifth harmonic of two square wave gratings that drift in opposite direction. The phase of one of the fifth components was ke...
