Influence of mechanical hippotherapy on skin temperature responses in lower limbs in children with cerebral palsy.

Therapeutic horse riding is often employed for disabled children. The aim of the present paper was to determine the influence of exercise in a mechanical saddle, imitating horse's walk, on the skin temperature responses in lower limbs in children with cerebral palsy. Sixteen children, aged 14-16, were enrolled into the study. Skin surface temperature was assessed with thermography, using an infrared thermovision camera, AGEMA 550, before and directly after 20 +/-5 min of exercise. The findings demonstrate that mechanical hippotherapy provides an exercise stimulus that is capable of inducing a visible change in skin temperature of paralyzed limbs. The change, however, is one of a decrease in skin temperature, which points to acute vasoconstrictive effects of exercise and to decreased skin blood flow. The results, therefore, do not support the use of mechanical hippotherapy in children suffering from cerebral palsy, with a hope to stimulate blood circulation to spastically altered limb muscles and thereby to improve physical disability, at least in a short-term exercise paradigm.
