[Our aim is to define optimal stimulation patterns for controlling lower limb movements of spinal cord injured patients. Here we report on a study about cycling movements of healthy subjects under regular conditions and spinal cord injured patients whose cycling movement was generated by functional electrical stimulation. The stimulation pattern required for coordinated activities of lower limb muscles of spinal cord injured patients was improved by using the observations what we gained from measuring and analyzing cycling movements of 42 young healthy subjects. Kinematical parameters (joint angles) and muscle activities (EMG) were recorded simultaneously by an ultrasound based movement analyzing system. We replaced the cycling program of the commercially available stimulator with a new one that we developed on the basis of the measured healthy cycling movements. We present that our new stimulation patterns provided a great increase in the performance of our spinal cord injured patients.]

[EFFECT OF EPILEPTIC SEIZURES ON THE HEART RATE]

TÓTH Vanda, HEJJEL László, KALMÁR Zsuzsanna, FOGARASI András, AUER Tibor, GYIMESI Csilla, SZŰCS Anna, JANSZKY József

[Background - Sudden death appears in 8-17% of epilepsy patients non-responding to antiepileptic therapy. Some studies suggest that the most common cause of death is seizure-related cardiac arrhythmia. Aim of study - To analyze the alteration of the heart rate six hours before and after the seizures. Methods - Eighteen patients suffering from focal epilepsy were examined before epilepsy surgery. Video-EEG-ECG was carried out for 2-10 days, and 32 seizures were registered. Analysis of the heart rate was based on the 5- minute-long epochs of the ECGs taken at the 5-10-15- 30th minutes and at the 1-3-6th hours before and after seizures. Results - The heart rate increases (from average 69 beats/min to 92 beats/min, p<0.001) immediately after seizures, tough significantly higher heart rate was observed 3 hours after seizures. There were no patients with severe periictal bradycardia. In one of our patients, ectopic cardiac rhythm occurred after a generalized tonicclonic seizure. Conclusions - We can conclude that the sympathic activity increases while the parasympathic activity decreases after seizures. The observed alterations lasted for a long time and predict to fatal arrhythmias. These suggest that sudden death in epilepsy can be induced by cardiac arrhythmias connected with epileptic seizures.]

The effects of the level of spinal cord injury on life satisfaction and disability

GULSAH Karatas, NESLIHAN Metli, ELIF Yalcin, RAMAZAN Gündüz, FATIH Karatas, MÜFIT Akyuz

Introduction - Spinal Cord Injury (SCI) may often lead to significant disability in affected individuals and reduce life satisfaction. Herein we aimed to investigate the effects of the level of injury on disability and life satisfaction as well as the relation between life satisfaction and disability. Methods - Patients with at least one-year history of SCI were included. Demographic-clinical data of patients were recorded. The Craig Handicap Assessment and Reporting Technique-Short Form (CHART-SF) was used for quantifying the degree of patients’ disability. Life satisfaction was assessed by the Satisfaction with Life Scale (SWLS). Results - Of the 76 patients, 21 (27.6%) were tetraplegic and 55 (72.4%) were paraplegic. SWLS was found to be similar in tetraplegic vs. paraplegic patients (P=0.59), whereas CHART parameters such as physical independence, mobility, occupation, and total CHART value were significantly higher in paraplegic patients (P=0.04, P=0.04, P=0.001 and P=0.01, respectively). Social integration was found similarly high in both groups. There was a positive correlation between elapsed time after the injury and CHART physical independence, occupation and the level of economic sufficiency (P<0.01, P<0.01, P=0.01). Excluding the economic sufficiency (P=0.02), there was not any other association between the rest of CHART parameters and SWLS. Conclusions - According to our findings, although the level of injury seems to be influential on disability, it seems to have no significant effect on life satisfaction. Since the only thing that positively affects life satisfaction is economic sufficiency, more emphasis should be placed on regulations that increase the return to work in patients.

[Exploration of quality of life goals in rehabilitation of persons after spinal cord injury]

TÓTH Katalin, PUTZ Miklós, KULLMANN Lajos

[Background and purpose - Surveyed references indicate improvement of rehabilitation outcomes if based on exploration of personal rehabilitation goals or quality of life goals. Purpose of our study is mapping of quality of life goals of persons entering rehabilitation by structured interviews, and study of applicability of the method. Methods - Structured interviews have been performed with persons consecutively admitted for their first rehabilitation intervention, meeting inclusion criteria. World Health Organization’s quality of life measure brief version and disability module served as guideline for the interviews. For study any negative effect on rehabilitation of our approach we have compared rehabilitation outcomes of consecutively admitted persons immediately before starting our study (58) and those with closed rehabilitation intervention (53). For this purpose the Functional Independence Measure was used. Finally content analysis of the interviews has been performed. Results - In 24 cases complications and psychological instability have prevented the inclusion, seven persons did not agree into participation in the study. Of the 71 interview participants the rehabilitation of 53 persons concluded. Their rehabilitation outcomes are better as of the control group significant difference has been measured in the social functions domain. Quality of life of included persons decreased during the rehabilitation process insignificantly, the autonomy domain showed insignificant improvement, the inclusion domain did not change. Content analysis revealed the outstanding role of the family among quality of life goals. Conclusions - Reported results indicate that exploration of quality of life goals of persons in early phase of rehabilitation after spinal cord injury is feasible. The selected quality of life measure may well support the interviews.]

[The complex intensive care and rehabilitation of a quadriplegic patient using a diaphragm pacemaker]

FODOR Gábor, GARTNER Béla, KECSKÉS Gabriella

[A 21 year female polytraumatized patient was admitted to our unit after a serious motorbike accident. We carried out CT imaging, which confirmed the fracture of the C-II vertebra and compression of spinal cord. Futhermore, the diagnostic investigations detected the compound and comminuted fracture of the left humerus and femur; the sacrum and the pubic bones were broken as well. After the stabilization of the cervical vertebra, a tracheotomy and the fixation of her limbs were performed. She spent 1.5 years in our unit. Meanwhile we tried to fix all the medical problems related to tetraplegia and respiratory insufficiency. As part of this process she underwent an electrophysiological examination in Uppsala (Sweden) and a diaphragm pacemaker was implanted. Our main goal was to reach the fully available quality of life. It is worth making this case familiar in a wider range of public as it could be an excellent example for the close collaboration of medical and non-medical fields.]

[Physical and electrophysiological aspects of electroconvulsive therapy (review)]

GAZDAG Gábor

[Personnel and technical conditions for ECT (electroconvulsive therapy) is legally determined. In this article the author reviews studies focused on the technical questions of ECT. After the comparison of the unilateral and bilateral electrode placement an analysis is given on the physical properties of the stimulus used to elicit seizures. After discussing the questions of dose, vaweform frequency and polarity, the anatomical and physiological factors of impedance are evaluated. The author then discuss gender, age and encephalopathy as factors influencing seizure threshold. The connection between symmetry, regularity, and postictal suppression registered on the EEG and efficacy is observed. The EEG and EMG concordance is supposed to be connected also with the efficacy. In the discussion the author gives recommendations based on the literature.]

[Kennedy’s syndrome - bulbo-spinal muscular atrophy]

SZABÓ Antal, MECHLER Ferenc

[Kennedy syndrome is a late-onset, bulbar-spinal type of muscular atrophy, with X-linked recessive inheritance. The characteristic features of the disease become prominent in the 4-5th decades: proximal muscle wasting and weakness, bulbar signs, fasciculations in skeletal muscles, subtle signs of endocrine dysfunction, such as gynaecomastia or testicular atrophy. The electrophysiological examinations are the keypoint to the diagnosis. Electroneurography shows normal conduction velocity in peripheral nerves, but the sensory nerves usually show axonal degeneration, which causes only very mild or subclinical neurological deficits. Electromyography shows chronic anterior horn cell degeneration in skeletal muscles. Molecular genetic diagnosis was introduced in 1991, when an abnormal expansion of CAG repeat was found in the first exon of the androgen receptor gene on chromosome X with a frequency of 100% in the affected population. Since the progression is very slow and these patients can expect a normal life span, it is essential to distinguish this syndrome from other, often more severe diseases, such as ALS. There is no proven therapy for Kennedy's disease yet. This is the first case of Kennedy's disease published in Hungary.]
