Stroke Training and Awareness Resources (STARs)
- Since Dejerine and Roussy’s description of central pain (CP) after thalamic stroke in 1906, thalamic pain has been the best-known form of CPSP. We now know that a stroke anywhere along the spinothalamocortical pathway can cause this kind of pain after a stroke. The key problem causing CPSP is a disturbance of processing of sensory information
- CPSP may be described as burning, aching, lacerating, shooting, squeezing, or throbbing and can be aggravated by a range of stimuli including movement, temperature, touch or stress.
- Some useful definitions are:
- Allodynia – pain due to a stimulus which does not normally produce pain
- Dysaesthesia – an unpleasant, abnormal sense of touch
- Hyperalgesia – an extreme reaction to a stimulus which is usually painful
