The strappado position refers to any arm position where the arms are bound together behind the back and elevated. The strappado was and is used as a real-world torture and mutilation and we are therefore reluctant to use the term, but it is so widespread that it is unavoidable. It is vitally important to note that the leverage of the arms can in principle dislocate the shoulders (which is how real-world torturers use it) and that one must therefore be very careful when rigging the position- one should be careful that a sudden slip will not result in injury. On no account attempt to suspend or semi-suspend anyone by their arms in strappado!
The position shown here incorporates several elements. The crotchrope is not attached to the rest of the bondage and serves primarily as decoration and tittilation. The ankles are bound to a spreader bar, keeping them far apart. The subject was ordered onto her tiptoes and to remain there. Her elbows were again bound together behind her back, which intensifies the effect of the position. Her arms were hoisted to a stout suspension point, but a rope with considerable stretch was used in order that if she did slip or faint there was considerable elastic give in the system.
All that said, the position is very aesthetically pleasing, very pratical, allows for rearward penetration of the subject and is an excellent means of display to boot.
