Abstract
A method of measuring hyperactivity includes determining the total number of movements of the subject as well as the number of movements which occur at a rate exceeding a preselected threshold. When the rate exceeds the threshold, biofeedback conditioning may be employed to alert the patient in order to condition him against such activity. An apparatus employing the method includes a counting unit worn on the belt of the subject. The counting unit records movement detected by a set of mercury switches. The total number of times a mercury switch is opened is counted as well as the number of times the rate threshold is exceeded. This information is stored in the counters for subsequent evaluation. An oscillator circuit gated by the counting unit provides an audible signal to the subject when the rate threshold is exceeded. A readout and display circuit is utilized for obtaining the information stored in the counting unit.
