Factor analysis, on the other hand, revealed a two-factor structure corresponding to the evolution (2nd factor, F2) and dissolution (1st factor, F1) of a synergy movement pattern. The scatter diagram of factor scores (F1, F2) showed a ??-shaped distribution composed of vertical and horizontal branches. The two-dimensional scatter diagram exhibits virtual continuity of F1 and F2, being consistent with the unidimensionality indicated by the scalogram analysis. The patients at the stage of synergy

... pattern formed the vertical component and those at the dissolution stages the horizontal, the jointing corner representing the turning point from evolution to dissolution of the synergy pattern.
