When you mention animal assisted therapy, most people think only of dogs. However, a study conducted by the REHAB Basel, the clinic for neurorehabilitation and paraplegiology, and the Swiss Tropical and Public Health Institute have found that animals such as guinea pigs, miniature pigs, rabbits and sheep improved social interaction, positive feelings and encouraged people to communicate more.
This is an important study which opens the door for other types of animals to help with severely brain injured people. In some cases smaller animals may be easier to incorporate into therapy sessions making it easier for rehabilitation centers. How wonderful the relationship is between the animal kingdom and humans.
