Ledged Beam Test

The Ledged Beam test is used to assess sensorimotor deficits in rodent models of CNS disorders. Subjects walk across an elevated beam that gradually narrows in width as they approach their home cage. The beam features a ledge that catches the animal’s paw if it slips off the edge. Misplacements of the paw off the beam are video recorded and scored. This test is used to phenotype strains of transgenic mice and evaluate novel therapeutic approaches.
