Disturbances of discriminative sensation in patients after ischemic and haemorrhagic stroke, illustrated with example of area of innervation of median nerve and radial nerve
Journal Title: Annales Academiae Medicae Silesiensis - Year 2014, Vol 68, Issue 5
Abstract
INTRODUCTION One of the basic functions of the nervous system is sensation, which enables the recognition and, as a consequence, appropriate reaction to various stimuli from external and internal environments. Sensation disturbances of a central origin were essential to this study. The purpose of this study was to assess the disturbances of sensation in the paretic upper limb and determination of the dependence between the kind of stroke and the degree of tactile sensation impairment. MATERIAL AND METHODS The study was conducted among patients hospitalized at the neurological department. A total of 40 patients (22 women and 18 men) after ischemic and haemorrhagic stroke were enrolled in the study. The mean age was 58 years. Two methods were employed in the area of innervation of the median and radial nerves: Weber’s twopoint discrimination test and an aesthesiometer. RESULTS The research has shown that regardless of the kind of stroke suffered, there is always an occurrence of tactile sensation disturbances within the area of paresis. The disturbances of sensation were found to be more serious in patients after haemorrhagic stroke. A correlation was found between disturbances of discriminative sensation and disturbances of skin sensation. As a result of the applied therapy, gradual improvement of both skin and discriminative sensation was observed in both research groups. CONCLUSIONS Both methods have confirmed that patients after haemorrhagic stroke suffer from more serious disturbances of skin and discriminative sensation than patients after ischemic stroke.
