## Abstract

A modular patient support system for use in ambulating a patient across a floor, comprising a primary module and a secondary module. The primary module has a primary base and a primary deck arranged for movement relative to the primary base, and the primary deck defines a first patient support area. The secondary module has a secondary base adapted for movement along the floor relative to the primary base and a secondary deck arranged for movement relative to the secondary base. The modular patient support system is operable between a docked configuration where the secondary deck cooperates with the primary deck to define a second patient support area larger than the first patient support area, and an undocked configuration where the secondary module is spaced apart from the primary module to facilitate ambulation concurrent with the secondary module across the floor away from the primary module.
