The worst pain of the person was nociceptive in 52% and neuropathic in 48% of the cases; 46% of nociceptive pain was located in the neck-shoulder region, whereas 67% of neuropathic pain was located in the sublesional part of the body. In 48% of the whole population, spasticity was observed but only 74% of them had pain. Being old and female are associated with high pain development, OR (95% CI): 1.24 (1.01-1.04) and 1.83 (1.05-3.20), respectively.
