Research | Clinical Effects of Deep Touch Pressure

Dr. Temple Grandin (born August 29, 1947) is an American doctor of Animal Science, a professor at Colorado State University, best selling author, and consultant to the livestock industry on animal behaviour. As a person with high-functioning Autism, Grandin is also noted for her work in Autism advocacy and is the inventor of the squeeze machine designed to calm hypersensitive people.

The initial concept used for the development of CalmWear originated from Dr. Temple Grandin's research on the calming effects of Deep Touch pressure. The following is an excerpt from her 1992 paper.

Clinical Effects of Deep Touch Pressure

Deep touch pressure is the type of surface pressure that is exerted in most types of firm touching, holding or swaddling. Occupational therapists have observed that a very light touch alerts the nervous system, but deep pressure is relaxing and calming.

Deep pressure touch has been found to have beneficial effects in a variety of clinical settings (Barnard and Brazelton 1990, Gunzenhauser 1990). In anecdotal reports, deep touch pressure has been described to produce a calming effect in children with psychiatric disorders.

Deep pressure stimulation, such as rolling up in a gym mat, has been used to calm children with Autistic Disorder and ADHD (Ayres 1979, King 1989). Lorna King (personal communication, 1990) reports that children with sleeping problems appear to sleep better inside of a mummy sleeping bag, which adapts to fit the body snuggly.

It also has been used to reduce tactile defensiveness in children who cannot tolerate being touched. McClure and Holtz-Yotz (1991) found that deep pressure applied by foam-padded splints on the arms reduced self-injurious behaviour and self-stimulation in an autistic child.

Research on Autistic children indicates that they prefer proximal sensory stimulation such as touching, tasting, and smelling to distal sensory stimulation of hearing and seeing (Kootz et al. 1981). Autistic children will often seek out deep pressure sensations. At various lecture meetings of parents of Autistic individuals, parents have reported to me various types of pressure-seeking behaviour of their offspring, such as wrapping arms and legs in elastic bandages, sleeping under many blankets even during warm weather, and getting under mattresses. A high functioning Autistic woman stated, "I need heavy blankets on me to sleep well, or else my muscles won't calm down."

At CalmWear our Calmtex™ fabric and design is based on the research of Grandin (1992), Ayres (1979), and King (1989). We produce discrete undergarments for children and adults that will create the effects of Deep Touch Pressure.

Sizing Charts

We have already allowed for the correct amount of gentle sensory compression, so please use the exact chest measurement when deciding on size.

If your measurement is between two sizes, you are best choosing the smaller size. CalmWear needs to provide gentle sensory compression to the muscles, to work effectively.
