TailSuspScan is a component of our DepressionScan Suite. The Tail suspension test involves holding the animal by the tail, and suspending it dangling in the air.  Observation is made with regard to animal’s struggling and immobility.  Human observation is tedious, time consuming, and expensive. 
TailSuspScan automates the entire observation process of tail suspension experiment.  It automatically detects not only the time the animal spends in an immobile state, but also the time animal is struggling.  In addition, TailSuspScan has the capability to differentiate between active struggling mobility and passive swinging mobility. The latter can either be grouped into the Immobility category or grouped with the Mobility class, thus making the results of Immobility much more precise according to the user’s protocol. Only the motion caused by active struggling behavior is captured as Mobility. Various settings are available that allow the user to adjust the definition of what is Immobility, Passive Mobility, and Active Mobility.
