Anti-wrinkle injections and spasticity
Has anyone had anti-wrinkle injections for spasticity and if so did it help?
The reason that anti-wrinkle injections work to minimise the appearance of wrinkles is because they relax or mildly paralyse certain specially selected muscles in the face. When these muscles contract they cause skin to wrinkle: relaxing them means that the wrinkles won’t form. People who have muscle spasticity also benefit from having certain specifically selected muscles relaxed as well. For example, in someone who has had a stroke a muscle may be contracted in such a manner that may be uncomfortable and interfere with everyday activities. Selectively weakening that muscle can be very useful in minimising discomfort and even pain. Very large doses are needed, as the muscles involved are much bigger than the facial muscles involved in wrinkling.
