Background: Observation and research on pure and natural movements and movements born of human nature have been carried out for many years. However, biomechanics study is still very less for the complex movements from lying on a floor to standing position. In particular, there is still little scientific and scientific research on the movements observed during the unconscious developmental process until babies acquire standing and walking. In this study, two patterns: Spiral and Parallel which relates baby motion development were focused. We examined the characteristics of the changes in the motion trajectory and the body pressure dispersion from the biomechanical point of view in the motion from the floor to standing. Developmental studies of human fundamental movements may be associated with appropriate signals to cells, tissues, and organs, as well as with health maintenance and development and care applications for the sick, disabled, and also the healthy people. This study will provide basic data.Methods: Healthy volunteers who finished training about baby development movement course were recruited by a snowball sampling. Two fundamental Spiral and Parallel movements from a supine position to a standing position on the floor, which are said to reproduce a general developmental process naturally acquired in the growth process of a baby, were analyzed for 5 times each. The three procedure was analyzed with a 42 segments model using a 3D motion analysis VICON. The analysis of observation for the movement process, the force plate, and the movement lotus were examined.Results: One female volunteer aged 30's who finished the training was analyzed in Spiral and Parallel movements for 5 times each. The Spiral movement was distributed to various parts of the body, and repeated circular movements irregularly in a wider space. The Spiral movement was observed a circular trajectory like a figure eight motion as a whole. The Parallel movement was a straight line on the sagittal plane, shifting the body weight back and forth, repeated flexion and extension movements, and moved upward. The motion locus of the linear waveform was repeatedly operated, and it was indicated that it moved back and forth on the sagittal plane in the Parallel movement.Conclusion: The Spiral movement was distributed to various parts of the body, and repeated circular movements in a wider space of sagittal plane, frontal plane and horizontal plane, and moved upward. Spiral movement was a circular trajectory like a figure eight motion irregularly distorted in wider three dimensions. The Parallel movement was a straight line on the sagittal plane, shifting the body weight back and forth, repeated flexion and extension movements, and moved upward. Parallel movement was the operating locus having a linear waveform back and forth on the sagittal plane.
