How do I train a horse to stand quietly at a mounting ramp for extended periods?

The mounting ramp in a therapeutic riding program allows participants with limited mobility to be positioned at the horse's side and then moved onto the horse's back with support from multiple helpers. The horse must stand completely motionless during this process, which can take several minutes for participants who require significant physical assistance and for whom any sudden movement from the horse creates a dangerous situation. Training the mounting ramp stand begins with familiarizing the horse with the ramp structure itself. Allowing the horse to investigate the ramp, walking it past and around the ramp, and eventually leading it to stand alongside the ramp while handlers move on and off develops the horse's familiarity with the structure before any actual mounting is practiced. The sounds associated with ramp mounting — the footsteps and movement of multiple people on the ramp, the sounds of wheelchairs or walkers being positioned, and the physical sensations of participants being lifted and positioned onto the horse's back — each require specific desensitization. A horse handler positioned at the horse's head during mounting provides both physical steadiness and a focus point for the horse. A horse that stands so reliably during ramp mounting that the handler's attention is only needed for direction rather than physical restraint has reached the standard that safe therapeutic riding requires.
