Abstract

This paper presents a new method for locomotor activity (LA) measurement in small laboratory animals. A method was developed in order to add LA measurement capability in biotelemetry systems in which implant powering and communication is based on inductive coupling. That enhacement is done without the need of additional resources in the implanted side. After discussing the mathematical formulation, an example is presented for which are obtained the most adequate parameters for LA measurement in a typical system of biotelemetry in small rodents. Limitations and advantages of the method conceived also are discussed.
