Studies have shown that one of the major barriers to effective physical therapy is the mental state of the patient. Feelings of depression and helplessness can lead to a lack of motivation to perform necessary exercises. In children dealing with chronic illnesses or long term in-hospital care, psychological distress can hinder recovery. Luckily, the benefits of animal therapy are starting to become scientifically documented and more widely accepted. Organizations like Intermountain Therapy Animals are working to connect patients with therapy dogs, and working miracles like the one below. 

A head-on collision left Caleb with multiple broken bones and TBI, traumatic brain injury. His recovery was so slow, his father was beginning to lose hope. But then, while still barely mobile, Caleb was introduced to Colonel, a volunteer therapy dog. The effect was immediate. A testament to the healing power of animals, Colonel's presence was transformative. Caleb was no longer struggling through a series of disjointed and repetitive motions, he was engaged in play with a wonderful new friend. The difference in his mobility and ability to interact with others in the short span of a month is astounding.
