| Equilibration is one of the most important functions of nerve system and locomotor system. Dysfunction of equilibration is often seen in many nerve system diseases.Detection of balance dysfunction used to be performed by some physical methods, such as Romberg's sign, which is insufficient in objective and effects and often leads to bad acknowledgements of the extent and the properties of balance dysfunction in different neural diseases. How to detect the balance dysfunction in quantity is always a problem for a long time. Postural sway is new method for detection of balance dysfunction from vestibule, visual or body-sensory diseases. The clinical purpose of this method is that it can offer some valuable date in quantity for diagnoses of human balance dysfunctions. Up to now, the application of this method is just at its start point. The value and range of its application is not well known, and a united criterion is in need.So, a evaluation for the application of EAB-100 stabilometer in some nerve system diseases is given there. All the work is divided into three parts: 1.set-up for the normal value. 2. discussion of the values of stabilometer's application in diagnosis of ataxia. 3. discussion of the values of stabilometer's application in therapy of vertigo from vascular diseases.Methods and Results:l)In this study, 240 cases healthy persons different in their ages were examined for their equilibration function. Most of the indexes of equilibration in open-eyes condition are lower than in close-eyes condition. These indexes are gradually decreasing with the increasing of ages and increasing with aging. The 20-29 years group owes the lowest indexes, which is significantly different from the data of 30-39 years group(P<0.05),but isn't from 10-19 years group. Centripetal type is the most common type of postural sway, succeeding the diffusive type and forward-backward type. Comparing the indexes of common people from all three groups, we found the equilibration ability is the best in 30 years group, and significantly different from over-50 years group.2)Study of 185 cases of ataxia show that the postural sway tract of sensory or cerebellum ataxia is diffusive type while for healthy people is centripetal. The tract of vestibular ataxia is between the two groups mentioned above. Difference between data from healthy people and patients is significant and that the tract of vestibular ataxia is longer and faster than healthy people (PO.01). There is nosignificantly difference between sensory ataxia and cerebellum ataxia3)Data from 50 cases of vascular vertigo patients showed that the tract is diffusive type and the center of gravity can reach to a wider range and a faster velocity (.PO.05). Swaying area of vascular vertigo patients hi opening-eyes is very bigger than in closed-eyes (P<0.01).Treated by Sibium, symptoms turned better. Changes of standing stable picture between before and after therapy match the changes of clinical symptoms and results from B ultrasound of cervical vessels and TCD.Proofs mentioned above seemly demonstrated that:l)The ability of equilibration decrease with aging, which is significantly after 60 years old. The function of vestibule decrease after 50 years.2)Postural sway is very useful in analyzing the function of vestibule-spinalcord reflex in all kinds of ataxia patients. It can be used to perform a gross selection for ataxia patients, and help to differ the types of ataxia.3) RMS Area maybe the most important index in postural sway to reflex the extent of equilibration dysfunction of vascular vertigo patients. It is not only benefit to differing the types of vertigo but benefit to objectively valuing the changes before and after therapy.In a word, the utilization of stabilometer made it possible to detect the function of equilibration in quantity objectively, and bring us a new method to synthetically value the function of equilibration.With the utilization of stabilometer in diagnosis, differential diagnosis, prevention and rehabilitation, their... |
