Clinical and Research Professionals to Benefit From

Accuracy and Usability of New Activity Measurement Device

Stayhealthy Inc., a leading online company dedicated to empowering consumers to monitor their health and fitness, has launched and commenced delivery of the RT3 Triaxial Research Tracker, a new activity measurement device designed to set new standards for accuracy and usability in clinical and academic research studies.

John Collins, chief executive officer of Stayhealthy, made the announcement today.

The RT3 is an easy-to-use activity measurement and recording device that is part of a complete activity recording and measurement system for clinical and research applications. Using the RT3 and the RT3 docking station with Stayhealthy software enables research professionals to display performance graphs and activity unit data on their computers for use in assessing and tracking subjects in ongoing and comparative studies.

Designed to be the most accurate and user-friendly clinical-standard activity measurement tool, the RT3 is a pager-sized device worn on the waist that continuously tracks activity through the use of piezo-electric accelerometer technology that measures motion in three dimensions and provides triaxial vector data in activity units, metabolic equivalent units (METs) or kilocalories.

Stayhealthy has developed the RT3 in response to growing demand for a new, highly accurate tool for clinical and academic activity studies, in part related to increasing demand for weight management and fitness programs worldwide. The company is offering the product through the company's Web site at www.stayhealthy.com and through direct sales to research and clinical professionals worldwide. Stayhealthy has received advance orders for the RT3 from researchers in Taiwan, U.S.A., Netherlands, Germany, Singapore, South Africa, Portugal, France, Canada, Sweden and the U.K.

"The RT3 is a breakthrough product for researchers because it delivers highly accurate activity measurement data efficiently. The RT3 adapts easily to different study parameters and populations and supports compliance through ease of use," said Dr. Johnny Sawada, Pharm. D., senior vice president of clinical programs for Stayhealthy. "Additionally, ongoing development and use of the technology in the RT3 will significantly strengthen the quality of Stayhealthy's other accelerometer-based products, including the CT1 Personal Calorie Tracker."

Other features of the RT3 include: data resolution from one second to one minute sample intervals; data recording and storing capabilities for up to 21 days; manages and exports data list files; and allows researchers to report data as Activity Units, Kilocalories and METs. Adaptable to large or small population studies, up to 10 additional RT3 Activity Recorders can be operated from one RT3 Kit.

The predecessor of the RT3, the Tri-Trac R3D, was introduced in 1992. A bulky device worn on the waist, the widely used Tri-Trac was considered the worldwide research standard for activity measurement studies. In 1999, Stayhealthy purchased the technology used in the device from Reining International Ltd., and has improved accuracy and consistency through standardizing production of the accelerometers and the device, adapting the device to a Windows instead of a DOS-based operating system, and conducting validation studies with the Tri-Trac R3D to demonstrate the improved accuracy of the RT3.

Stayhealthy is leading the development of Web-enabled products and services for management and measurement of weight, blood pressure and heart rate, hearing loss, vision and colorblindness and respiratory function. Created for consumer and clinical use, the company's leading-edge products and services facilitate better communication and increase efficiencies between doctors and patients and healthcare facilities, reduce the need for in-person appointments and improve opportunities for early illness detection. In doing so, Stayhealthy's comprehensive home monitoring programs create mutually beneficial opportunities for a wide variety of industries and professionals such as self-insured employers, physicians, dieticians, nutritionists, fitness trainers, health club owners, insurers and others.
