[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.]

[Affective and cognitive decision making in major depression: influence of the prefrontal cortex, serotonin transporter genotype and personality traits]

MUST Anita, HORVÁTH Szatmár, JANKA Zoltán

[Patients with major depressive disorder (MDD) show neuropsychological impairments, including deficient executive functions and suboptimal decision-making strategies, which are mediated by several brain regions. In the development of these symptoms the pathology of the prefrontal cortex (PFC), including the dorsolateral, ventromedial and orbitofrontal regions, may also play an important role. Neuropsychological assessment is a useful tool in detecting and measuring these deficiencies, showing that patients with MDD exhibit altered sensitivity to reward and punishment. However, impairment of emotional decisionmaking strategies in MDD is influenced by genetic variations (5-HTTLPR polymorphism) and personality traits, which seem to have a higher predictive value on decision making performance than the clinical symptoms.]

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.

[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.]

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


[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.]

[The effect of an alternative training method on the pelvic floor muscle]

ARANYNÉ Molnár Tímea, SZABÓ Kinga, RÁZSÓ Katalin, DOMJÁN Andrea, SZŰCS Mónika, SURÁNYI Andrea, BÓDIS József

[Aim: In our study we analysed an alternative training method alone or in combination with pelvic floor muscle (PFM) with deep abdominal muscle strengthen the PFM better. Material and Methods: The study was conducted on women (n=5, mean age ±SD: 51,8 years, ±9,23 years). The Callanetics® gymnastics consisted of training sessions of 2x1 hours (10 weeks only Callanetics® exercises, 10 weeks in combined with PFM contractions). The subjects completed a questionnaire (risk factors, symptoms) and to measure the body parts’ circumference at 0. and 20. weeks. The measurement of the conditional capacitance of the PFM was performed by EMG before the gymnastics, then at weeks 10 and 20. We used R Statistics Software. Results: Significant decreseing were observed in the circumference of extremities and on isometric contraction improves (p=0.036). The dynamic strength showed an increasing tendency. Conclusion: The alternative training method significantly increased the maximum contractions of the PFM.]

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


[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.]
