Many clinical situations arise where an inexpensive and compact device for providing auditory feedback of a body or extremity position change might prove helpful. Such a device has been described recently by Bjork and Wetzel.1 Their device, which incorporated a mercury switch, was used for positional feedback during sitting. Seeking a more versatile device, we discovered an inexpensive and adaptable piece of equipment, the Personal Alarm—Safe HouseTM.* The sensitivity of the device can be adjusted by altering the slack in the cord passing from it. As the slack is taken up and the cord drawn from the alarm box of the device, the alarm sounds to provide auditory feedback.

Although many applications of the device are possible, we have used it for three specific purposes in our clinic.
