Incapacitance Meter for Mouse & Rat

Incapacitance Meter, also called Static Weight Bearing, is specially designed to quantify pain in rodents by measuring the static weight borne by each hind paw. It provides an objective index of discomfort by comparing left vs. right paw load, making it ideal for spontaneous pain assessment in small animals. Animals (mice or rats) are placed in a custom holder so that each hind paw rests on a precision force plate. As the animal shifts its posture, the Incapacitance Meter continuously records the force on each hind limb, calculating a symmetry index and average load over time. This noninvasive, automated minimizes stress on the animal and eliminate reproducible data for pain and behavior studies.

Overview
The Incapacitance Meter uses dual-channel weight sensors under each hind paw to capture weight distribution with high accuracy. Its real-time LCD touchscreen display shows left and right paw weights and symmetry index while a built-in computer analyzes data instantly. Tests run for user-defined periods (from a few seconds up to several minutes), during which the Incapacitance Tester averages the forces on each paw. The Incapacitance meter is specially intended for pain and inflammation research: it measures diminished weight-bearing on an affected limb as a sensitive indicator of spontaneous pain. Unlike reflex-based tests, this setup lets the animal stand freely at rest, providing an observer-independent measure of ongoing pain or recovery. All operations like start, stop, reset, calibration are controlled from the touchscreen control unit, enabling flexible, programmable testing without extra equipment.
