Physicians are found to have a great and increasing amount of patients suffering from vertigo in their everyday practice. For the treatment of the balance disorders, a vestibular training was introduced which played an influential role based on our study. Rehabilitation of patients having balance disorders is a known, major challenge for physicians. Vestibular rehabilitation therapy (VRT) is an exercise-based treatment program designed to promote vestibular adaptation and substitution. The goals of VRT are
1) to enhance gaze stability.
2) to enhance postural stability.
3) to improve vertigo.
4) to improve activities of daily living.
According to our clinical experiences, combination of medical treatment with vestibular training is beneficial for every vestibular disorder. The medical treatment modalities consist of vasoactive drugs (e.g. vinpocetine, piracetam) in chronic vestibular disorders. Authors demonstrated that vestibular physical rehabilitation therapeutic strategies produced improvement in different vestibular disorders, e.g. post-traumatic and migrainous vertigo.
Objectives: The objective is to show the usefulness of ultrasound-computer-craniocorpography in registration of balance disorders and to show effectiveness of the vestibular rehabilitation training.
For establishing necessary topodiagnostic procedure we are using a special neurotological history scheme, the computer based electronystagmography with caloric and optokinetic tests. Vestibular spinal testing is objectively recorded through craniocorpography (CCG). Craniocorpography was designed firstly as a non-electronic, simple office recording procedure for head and body movements. The regular craniocorpography procedure combines a stepping test (Unterberger, Fukuda) with a standing test (Romberg). Through a local positioning system a very precise localization of ultrasound markers is possible. Sound is moving through air with an average velocity of 330m per sec. By means of 3 microphones in fixed arrangement in space the sound signal can be precisely located according to its source. This is based on a mathematical analysis. This principle is installed into the ZEBRIS Coordinate Measurement System® (CMS). For analyzing headand body movements under the strain of different test profiles we apply the following voluntary tests which must be performed by the patient when being instructed by an investigator. The PC contains a program, which releases impulses of ultrasound through the markers of the test person. It also arranges the collection of the sound signals from the microphones. The patient is carrying a helmet with two ultrasound markers and a shoulder fixation with two other ultrasound markers. A computer unit is triggering the ultrasound impulses. Further back from and above the patient is the ultrasound receiver unit, containing several ultrasound microphones and data processors receiving the sound traces from the head and from the shoulders. The signals received are triggered by as well as sent to the computer unit. The computer unit calculates the spatial position of all the four ultrasound markers. The PC software shows the results obtained in each test online. Using ultrasound-markers on head and shoulders the computer can measure and analyze the numerical data of statokinetic tests of the patients suffering of vertigo or balance disorders. The Ultrasound- Computer-Craniocorpography (US-COMP-CCG), developed by Claussen, is a simple, reliable, quantifiable and reproducible method for statokinetic test investigation of vertigo victims. It consists of optically monitoring the patient’s head and body movements as they perform the classical Romberg’s and Unterberger’s tests. Our experiences show that ultrasound-computer-craniocorpography is useful test in the examination of the vertiginous population.
Mrs. SZ.L. is a 68 years old female, who has been suffering from central vestibular lesion more than a year due to cerebrovascular disorder. Ten days long vasoactive treatment and vestibular rehabilitation training was performed during her hospitalization. During the treatment her stability improved, and the DHI (dizziness handicap inventory) score, which was 56 points at the beginning of treatment, decreased to 28 points, showing that the severe deterioration in quality of life of patient improved to a mild deterioration. The figures illustrate the decreased imbalance after the combined treatment, registered by ultrasound-computercraniocorpography in both of the statokinetic tests (Figures 1-4).
With the appliance of neurotological examinations and the assistance of ultrasound-computer-craniocorpography, we are able to exhibit objectively the existence of vestibular disorder and detect the improvement after the suggested combined therapy.
