The relationship between nocturnal motility and the enuresis alarm device.

The mode of action of the enuresis alarm is not clear. Earlier work suggested that the wire mesh itself may alter sleep and in this way affect nocturnal enuresis. Seven healthy males have been studied within a two-period cross-over design in which their nocturnal motility, on and off an enuresis wire mesh, was recorded using a motility bed. There were no order, treatment or day effects in any of the variables studied. However, the mean hourly motility for each subject averaged over the three nights shows a substantial trend towards increased motility on the mesh. This lends some support to the hypothesis and merits further study.
