Analysis of voided urine volumes measured using a small electronic pocket balance.

The aim of this research was to analyse variations in voided volumes and duration and time of voiding during daily activities on a physiological basis, and to explore the possible diagnostic value of the associated parameters. A small electronic device was developed to accurately measure voided urine volumes in healthy volunteers during consecutive periods of two to three weeks. In subsequent analysis, the voided volumes were related to the time interval between voidings and the duration of voiding. Three parameters could be identified that quantify different aspects of bladder capacity (modal volume, maximum volume and a threshold volume in the relation between average flow-rate and voided volume). By relating voided volumes to the time interval between voidings the circadian rhythm in urine production was detected.

A device for long-term ambulatory monitoring in trans-tibial amputees.

Long-term monitoring of walking in trans-tibial amputees (TTA) is considered important for prosthetic prescription and therapy evaluation. The purpose of this study was to develop a device with the following design criteria: lightweight, easy attachment to the prosthesis, energy and memory capacity for five days and practical in clinical use. The prototype (CAMP: Continuous Ambulatory Monitoring of Prosthetic walking) consists of a cylindrical unit containing an accelerometer, a miniature computer and six batteries. Specifications, data acquisition and processing, instructions for users and first results are presented and discussed. The CAMP prototype proved to be a useful device for measuring relevant aspects of prosthetic use for up to five days.

A semiautomated test apparatus for studying partner preference behavior in the rat.

A semiautomated three-compartment box (3CB) for studying partner preference behavior of rats is described. This apparatus automatically records the rat's time spent in each compartment, as well as the locomotor activity (i.e., the number of visits an animal pays to each compartment). Software was developed for calculating partner preference scores. Behavioral testing in the semiautomated 3CB, which is a modification of an earlier version, is less time consuming and less laborious. Three 3CBs can be observed simultaneously by two trained observers, and the behavioral interactions of three experimental animals with the stimulus animals can be observed and scored by hand. The use of the new apparatus was validated by studying adult partner preference behavior of neonatally ATD-treated male rats. The collected data fully corroborate previous results, obtained in the earlier version of the 3CB, again revealing the behavioral bisexual nature of these ATD males. A new finding was the much higher locomotor activity of the ATD males compared to controls.

Computer-controlled wheelchair ergometer.

A new wheelchair ergometer has been designed in which a combination of realistic simulation of wheelchair propulsion--with adjustable parameters for rolling resistance, air drag, wind speed and slope--and force measurement has been realised. The static solution enables the measurement of physiological and kinesiological parameters. All data from force transducers in seat and backrest, torque transducers in the wheels and force transducers in the wheelframes as well as the acquired speed are sampled in a data-acquisition system. An offline curve processor allows the acquired data to be processed with standard or custom-programmed routines. Preliminary results have been added and are discussed.
