This YouTube video shows the procedure that I frequently use to apply a twitch to a horse. A simple hand twitch can be more successful than applying a mechanical twitch. A horse will often tolerate a squeeze of the nose by hand, when it will fight when it feels the metal from mechanical twitch. The simple “hand twitch” can be used for short non-painful procedures.
The most effective use of the “hand twitch” is the administration of an intranasal vaccine – i.e. Pinnacle brand Strangles vaccine by Pfizer. With the “hand twitch”, the plastic stylet can be placed deep in the nostril and the vaccine administered properly on the nasal mucous membranes.
