Abstract		Hemisensory loss has been associated with inferior results in level of functions and with longer rehabilitation. To establish if the functional reorganisation of the somatosensory system occurs also in chronic period after ischaemic stroke, we followed the alterations of the somatosensory functions in 28 patients with unilateral ishaemic cerebrovascular accident in the territory of the middle cerebral artery 1 year after the onset of the disease. The technique of recording somatosensory evoked potentials (SsEPs) was used. Not only conventional electrical stimulation of the median nerve (ESsEPs) but also natural mechanical stimulation of the thenar skin (MSsEPs) was used. Clinical testing involved somatosensory, motor and functional assessment. According to SsEP abnormalities over the contralateral somatosensory area, patients were graded into three categories: 1. with no elicitable SsEPs, 2. with abnormal SsEPs, and 3. with normal SsEPs. Clinical testing and somatosensory evoked potential recording was performed in the 2nd to 4th week, 6 months and 1 year after the onset of stroke. Clinical somatosensory assessment revealed somatosensory deficit in 12 out of 28 patients. No greater improvement of impairment of the position sense, vibration, light touch and pain sensation was determined by clinical assessment. In the acute period after stroke mechanical stimulation yielded more often abnormal SsEPs than electrical stimulation. Eight out of 28 patients had no elicitable MSsEPs, 6 patients had abnormal and 14 normal MSsEPs. ESsEPs could not be evoked in 5 out of 28 patients, in 7 patients they were abnormal and in 16 normal. There were no major changes of ESsEPs during the one-year follow-up period. MSsEPs improved in several patients (p = 0,0038). The largest improvement was in the first 6 months.
