Optimal integration of afference from visual, somatosensory and vestibular system is necessary for maintaining balance and often in the end for the functional indepencence of the patient. Examination of subjective vertical is a sensitive signifier for spatial orientation and the ability to discern graviception. By using clinical examination of subjective visual vertical it is possible to objectify and quantify graviception disorder excluding visual context. Current level of understanding in this field is briefly summarized in theoretical part of this study. In practical part subjective visual vertical examination by bucket-method was for statistically comparison of 29 patients after a cerebro- vascular accident with 34 healthy seniors. Hypotheses about the influence of a side of a lesion and a time elapsed since the lesions were also tested. The study concludes that the perception of verticality in patients after cerebro- vascular accident can be severely affected. Additionally, the study highlights the reliability of examination of patients after cerebro-vascular accident using clinically practical bucket-method.
2	Vliv věku na percepci vertikality u zdravých jedinců / The inpluence of age on the perception of verticality in healthy individuals Kmeť, Jan January 2014 (has links) INTRODUCTION - The ability to maintain stability while standing given by function of multisenzory system consists of vision, somatosensory and vestibular system and integration of the CNS. Due to aging there is a decrease of functional capacity of the organism, including these systems, resulting in a deterioration of the balance. Examination of subjective visual and haptic vertical is sensitive diagnostic criterion for functionality of these systems. OBJECTIVE - To compare the ability of verticality perception in young and elderly. METHODS - We examined 64 probands in visual and haptic subjective vertical. The first group consisted of 30 subjects aged 20 to 30 years. In the second group there were 34 people aged over 60. RESULTS - The values of the subjective visual vertical not differ between groups (0.1 ± 0.75 ř for the young and 0.1 ± 1.91 ř for seniors). Results of subjective haptic vertical differed on the significance level of p = 0.004 (0.8 ± 3.67 in the young and 3.7 ± 4.15 for seniors). CONCLUSION - Because subjective haptic vertical is diagnostic criterion mainly for the somatosensory system, we can assume that this particular system is responsible for a decrease in functional capacity and deterioration of stability in the elderly.
