"These children have a disorder that can make it difficult to express how they feel, but it must be unpleasant to have cold hands and feet," says physiotherapist Lena Svedberg, author of the thesis. "I find it surprising that the matter hasn't been given more attention."
The thesis shows that skin temperature in brain-damaged preschool children in wheelchairs was several degrees lower than in children without neurological disorders. The temperature of their feet was three degrees lower and their hands two degrees lower than children without brain damage. The reason for their cold extremities may be that the brain damage affects the part of the nervous system that is not controlled by the will and which, among other things, regulates blood circulation, digestion and sleep.
"This hypothesis is supported by a study in the thesis that shows that children with cerebral palsy who had cold hands and feet also had problems with constipation, sleeping disorders, pain and impaired well-being," says Svedberg.
There is currently no established treatment for cold hands and feet, but a small pilot study - also part of the thesis - demonstrates that acupuncture might be effective.
"Acupuncture activates the nerve fibres that lead inwards and can affect activity in the autonomic nervous system," says Svedberg. "We could see that treatment raised skin temperature in some children with neurological disorders, but it is a very small study and more research is needed."
Parents are often anxious when children have cold hands and feet indoors, but the long-term effects on children are unknown.
"However, there are studies that suggest that balance reactions can be affected if the soles of the feet are cold," explains Svedberg.
Neurological disorders arise from problems with or damage to the brain and the central nervous system. Some develop during adulthood, whilst others are present from birth. Neurological disorders in children include cerebral palsy, myelomeningocele and various neuromuscular disorders.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
