Analysis of fundamental receptive movements and those which are a ‘development’ of the ‘fundamental’ moves; in respect of the two root arm movements, regular hand technique (sei te) high in (jodan uchi te), and low out (gedan soto te) on the one hand, and reversed hand technique (gyaku te) low in (gedan uchi te) and high out (jodan soto te) on the other, there was difference of opinion in respect of mechanical evolution of movements and the terms applied to describe these actions. A large part of the problem was semantic in nature and one regarding terminology or classification used. It should be noted that any classification of these techniques will be arbitrary to a greater or lesser degree. A classification could be made upon what feels ‘natural’ and what feels less natural in terms of physiological positioning. Alternatively one could look at the mechanical processes going on with the arm during the execution of one of these techniques.
The ulnar and radius lie side by side when the palm of the hand is supinated (turned upwards), and when the palm is pronated (turned downwards) the ulnar crosses over the radius. If we continue the movement top its full extent with the palm turned outwards, the ulnar and radius are fully crossed.
Strictly, it would be wrong to describe one position as ‘natural’ and the other ‘unnatural’ as it would be to describe the positions as ‘regular’ and ‘irregular’, ‘normal’ and ‘reversed’ or ‘primary’ and ‘secondary’. It can feel just as natural to position the arm with the bones crossed as it does with them uncrossed, unless the rotation is taken to its fullest extent.
Thus the relationship can be made of inwards sword hand and outwards ridge hand where the ulnar and radius are lying side by side on the one hand, and inwards ridge hand and outwards sword hand with inwards ridge hand on the other. The process of pronation leads to an extreme crossed bones position in the case of an outwards palm (high or low) or an inward backhand (high or low).
Supination and pronation are perhaps two acceptable descriptors that will allow for an understanding and accurate description of the hand techniques involved.
The conclusion therefore must be that it actually doesn’t matter what hand positions are used to effect the regular hand technique or the reversed hand technique. Both palm and backhand alternatives should be explored however.
In conclusion I would say that it is relatively easy to see how the bones of the forearm work in conjunction with each other and when we are contacting with one or two bones and crossing or uncrossing the bones.
A way of reconciling the differing opinions revealed on this brief study is to reflect upon what I have said above for it is of no matter in the continuum scheme of things for it is dependent upon whether there is a need to protect the inner aspect of the arm, for some hand control or for some subsequent counter. We have traditionally done a) High palm in to low palm out and b) low back hand in to high palm out. In actuality the second finishes with a back hand out that turns into a palm control and so is not a ‘pure’ technique, rather a combination sequence albeit done in such a slick manner as to make this reasoning questionable. On reflection I now propose practising: a) high palm in to low back hand out. b) low palm in to high (hooking) back hand out. c) high back hand in to low palm out. d) low back hand in to high palm out as a standard. The sword hand and ridge hand variants may be rehearsed by longer term members, for without control they can be hurtful.
