Abstract

In Reply.—  Dr Payne's suggestion for a warning label is a practical one. Such a stick-on label is available from Vendo of California, free. However, the label is too small, measuring 6.4×8.3 cm (21/2 × 3 1/4 in). It is removable and it is not issued with the machine. To be effective, such a label should be large, nonremovable, part of the manufactured machine, and displayed prominently on the front of the machine at eye level.I believe that these machines are intrinsically unstable and that redesigning is necessary. They are top-heavy, standing on a narrow base. Hence, they tip over at very small angles of inclination. When interviewed, the patients stated that it was easy to tip the machines, despite their intimidating size and weight. Additional engineering analysis has revealed that even smaller forces applied correctly can tip the machine. It is possible to rock the machine, using the
