Grip Strength

Rodent's grip strength tested by device and human hand

Description

In the grip strength test, the rodent is held by the nape of its neck and the base of its tail. Its forelimbs are placed on the tension bar and the rat is gently pulled back until it releases the bar. The distance the rodent pulls the bar before it releases its paw-grip is measured in grams of resistance by a strain gauge. Hind limb strength can also be assessed.

Purpose

The purpose of the grip strength test is to evaluate the strength of forelimb and hind limb muscles. This test is useful in detecting changes in motor function and muscle strength associated with drugs or other manipulations.
