Apparatus for conditioning treatment of enuresis

Recent experimental work is cited which has implications for basic equipment design. Some unsatisfactory earlier innovations are also briefly discussed.

The traditional pad and bell apparatus is not superseded but commonly exhibits defects and hazards for which the recessed electrode principle is introduced as a solution. New high-sensitivity requirements in circuitry to match the recessed electrode pad are met in an unusual and inexpensive way.     

A controlled trial of the treatment of nocturnal enuresis in residential homes for children

The present study was undertaken to evaluate the practicability and efficacy of treating enuretic children in residential Children's Homes by means of the enuresis alarm. A control group design was employed with 19 and 20 subjects in the treatment and control groups respectively. Eighteen of the nineteen treatment group children achieved initial arrest of enuresis in a mean of 11.9 weeks of treatment (range 5–28 weeks). Over the initial 12-week period, the treatment group showed a statistically significant reduction in mean wetting frequency, both over time and in comparison with the control group. After a follow-up period of at least 20 months. 17 of the 19 children were known to be dry. The results of an independent evaluation are reported, and it is concluded that alarm treatment is as effective and practicable in Children's Homes as it is in family situations.     

A delivery system for olfactory stimuli

This paper describes the design of a new method for controlling and administering olfactory stimuli—namely, thehood system. The hood system involves a stream of vaporized odor (at known concentrations) mixed with odorless air and pumped (at a constant flow rate) into an oxygen therapy hood. It is designed to be used with odorants in solution, such as essential oils, as the olfactory stimulus. The use of oxygen therapy hoods allows for the precise control of a constant concentration of odorized air over time, while allowing subjects to breathe normally. The hood system provides a natural administration of olfactory stimuli and the exact determination of the stimulus concentration. The use of this system will allow experimental conditions to be completely defined and results and replication studies to be accurately interpreted. The hood system is portable, cost effective, and constructed from readily available components. It is proposed that the hood system could be adopted to suit a wide range of olfactory research, particularly that in which the effects of chronic exposure to olfactory stimuli on cognition are examined.     

Overlearning in the conditioning treatment of enuresis: A long-term follow-up study

V studies have reported high rates of relapse following the otherwise highly successful conditioning treatment of childhood enuresis nocturna (Young, 1969). Relapse would seem to be a hazard inherent in this form of treatment, and to be independent of patient variables (Young and Morgan, 1972a). Use of the technique of intermittent reinforcement schedules (Lovibond, 1964; Turner, Young and Rachman, 1970) and of CNS stimulant drugs (Young and Turner, 1965; Turner and Young, 1966) to counteract the problem of relapse have failed to achieve satisfactory results.

Young and Morgan (1972b) have demonstrated the success of overlearning therapy in reducing the relapse rate. This regime requires the child to maintain or regain his learned nocturnal bladder control, to a success criterion of 14 consecutive dry nights, while drinking up to 2 pints of liquid in the hour before retiring. The present paper reports the experience gained in the counteraction of relapse by the use of overlearning therapy over approximately 4 yr at the Vale Drive Clinic, at which enuresis is treated by conditioning techniques (Young, 1965; Morgan and Young, 1972).     

Conditioning treatment of enuresis: Auditory intensity

The auditory stimulus characteristics of three commercially-produced enuresis alarms are described and the results of a clinical trial of the three alarm types are reported. No significant differences regarding outcome, either in terms of treatment efficiency or of subsequent relapse, were found.     

A feed delivery system for the study of choice behavior in cows

A feed delivery system for the study of choice behavior in cows is described. Supportive data are provided for six dairy cows exposed to two-alternative, concurrent variable-interval schedules.     

The effects of extending the CS-UCS interval on the effectiveness of the conditioning treatment for nocturnal enuresis

Previous studies of the “conditioning method” of enuresis treatment have confounded the effects of conditioning with those of nonspecific psychotherapeutic aspects of the procedure. The present study compared three groups of enuretic children: (1) under the conventional bell-light conditioning procedure; (2) under a similar procedure, but which involved a three-minute delay between wetting and alarm, and (3) under no-treatment conditions. Double-blind precautions were used. Results suggested that conditioning effects improvement over and above that effected by nonspecific influences. The findings are qualified by large variances in improvement, and by premature termination of the experiment.
