    Opis:
    Purpose: One of the aims of the treatment in ambulant cerebral palsy (CP) patients is improvement of gait. Level of gait pathology is assessed by instrumented gait analysis, including surface electromyography. The aim of this study was to investigate the relation of the abnormality level of the gait and the co-contraction of the agonist-antagonist muscles, and relation between symmetry left /right leg in gait and symmetry of muscular activity. Methods: Fifty one patients with Cerebral Palsy underwent clinical assessment and instrumented gait analysis, including surface electromyography. Signals were bilaterally collected from rectus femoris, medial and lateral hamstrings, tibialis anterior, lateral gastrocnemius and gluteus maximus. In older children additionally signals from soleus and lateral vastus were recorded. Sixteen gait variables were selected to calculate Gillette Gait Index, separately for left and right leg. From the envelopes the series of cross-correlation coefficients were calculated. Results: Weak correlations were found between averaged agonist-antagonist correlation coefficient and Gillette Gait Index. Differences between hemiparetic less-involved legs, hemiparetic spastic legs, and diplegic legs were found for co-contraction of rectus femoris and biceps femoris and for averaged agonist-antagonist co-contraction. The differences between hemiparetic and diplegic groups were found for some muscle correlation coefficients. Conclusions: The results obtained in this study show, that the activity pattern of the leg muscles is specific for a given patient, and the dependence of the kinematics pathology on the abnormal activation pattern is not a direct one.

    Opis:
    The functional gait problems encountered by stroke patients include impaired balance, abnormal gait pattern with marked asymmetry, pathological trunk and spinal motion. Many different methods of physiotherapy are used to improve functional ability (especially gait) in stroke patients, but their efficacy and outcome are often not objectively assessed. The goal of this paper is to compare two therapeutic programs: one that is traditionally used in our rehabilitation facilities (exercises in lying position, “open chain” exercises, isolated movements of extremities with trunk stabilization) and the new one (exercises in vertical position, sitting or standing, “closed chain” exercises involving whole paretic side of the body). Fifty one stroke patients, aged 34 to 79 years, participated in the study. Patients were randomly allocated to one of the two groups. Patients underwent clinical assessment (Fugl-Meyer, Rivermead Motor Assessment, Berg Balance Scale) and instrumented gait analysis (using six-camera VICON 460 system) simultaneously three times: prior to the beginning of the rehabilitation program, after 6 weeks of the program, and after another 6 weeks of physiotherapy, at the end of rehabilitation program. Results demonstrated that both rehabilitation programs improved the gait function and clinical status in patients suffering from stroke. Despite the differences between the two programs the progress achieved by the patients in locomotor function is similar. Two equivalent physiotherapy programs could be applied during rehabilitation process depending on the patient’s individual preferences and needs, as the amount of functional improvement provided by them is comparable.

    Opis:
    Stroke is the third cause of death in contemporary society and causes many disorders. Clinical scales, ground reaction force (GRF) and objective gait analysis are used for assessment of patient’s rehabilitation progress during treatment. The goal of this paper is to assess whether signal correlation coefficient matrix applied to GRF can be used for evaluation of post-stroke patients status. Group of patients underwent clinical assessment and instrumented gait analysis simultaneously three times. The difference between components of patient’s GRF (vertical, fore/aft, med/lat) and normal ones (reference GRF of healthy subjects) was calculated as correlation coefficient. Patients were divided into two groups (“worse and better”) based on the clinical functional scales tests done at the beginning of rehabilitation process. The results obtained by these two groups were compared using statistical analysis. Increase of median value of correlation coefficient is observed in all components of GRF, but only in non-paretic leg. Analysis of GRF signal can be helpful in assessment of post-stroke patients during rehabilitation. Improvement in stroke patients was observed in non-paretic leg of the “worse” group. GRF analysis should not be the only tool for objective validation of patient’s improvement, but could be used as additional source of information.

    Definicja przyczynowości w sensie Grangera stanowi kompromis umożliwiający statystyczne testowanie tej zależności. Liniowa przyczynowość to zawężenie tego pojęcia, w istocie chodziło o zależności procesów generujących dane. Istnieją testy dla zmiennych niestacjonarnych, testy przyczynowości nieliniowej itd. Omawiamy niektóre z nich. W części empirycznej stosujemy nieliniowy test Diksa-Panchenki do szeregów finansowych w celu sprawdzenia, czy wyniki różnią się od wyników testu Grangera.
    Granger causality is defined to allow for construction of statistical tests. Granger himself intended to describe, possibly nonlinear, dependencies between data generating processes and take into account informational content of interdependence between variables. There are tests for nonstationary variables, of nonlinear causality etc., we describe some of the methods. We apply to daily returns of exchange rate and stock indices the linear Granger test and the Diks-Panchenko test (for nonlinear dependencies), while taking into account influence of the recent crisis.

    Opis:
    Patients with malignant tumours of the oral cavity require its surgical removal and reconstruction of the bone and soft tissues. The grafts are obtained either from leg (fibula) or pelvis (iliac crest). The removal of grafts from the locomotor apparatus can impair the gait. The aim of this study was to find out how the localization of donor site influences the gait pattern. Methods: Results obtained for 30 patients were analyzed (16 fibula graft, 14 iliac crest graft). Patients underwent instrumented gait analyses three times (VICON system): before surgery, 2–4 month after the surgery, and 4–8 months after the surgery. Results: In both groups several gait parameters were changed. Two parameters changed in both groups: gait speed and cadence. In patients receiving iliac crest graft the changed gait variables were: pelvic rotation, hip range in sagittal plane (operated side), knee range in sagittal plane (operated side), foot dorsiflexion in swing on both sides. In patients receiving fibula flap the changed gait variables were: tilt, range motion of the tilt, minimum hip flexion (operated side), time to maximum knee flexion (non-operated side), GGI (non-operated side) and step length (nonoperated side). Conclusions: The primary gait deviations occurring after surgery, and the compensatory mechanisms which subsequently arise depend on the localization of graft donor site. The results indicate that the patients in whom fibula flap was used have less problems with gait pattern after the surgery than the patients receiving iliac crest graft.

    Opis:
    Purpose: Patient recovery after a surgical procedure depends, among other factors, on the amount of the body weight with which patient loads lower limb. Research studies report different results of the degree of body weight with which lower limb is loaded during three-point crutch gait. The aim of this study was to evaluate the level of the ground reaction forces (GRF) during crutch gait used by patients after total hip arthroplasty (THA) in the first week after discharge from the orthopaedic units. Methods: Ten female patients diagnosed with primary unilateral coxarthrosis participated in a single measurement session. In order to record kinematic and dynamic variables of this gait pattern motion analysis system was used together with two force plates. The static test of body weight distribution between lower limbs was performed on a dual-top stabilometric plate. Results: The average peak values of loading on the operated (O) limb during mid stance and terminal stance of three-point crutch gait were 64.6% and 64.3% of body weight (BW), respectively, whereas in the case of the nonoperated (NO) limb 103.5%BW and 108.8%BW, respectively. The maximum loads on the crutches were significantly higher (by 9%BW) on the NO side as compared to the O side ( p < 0.05). During the static test, average values of body weight distribution on the O and NO limb were 36%BW and 64%BW, respectively. Conclusions: The patients showed surprisingly similar level of loading on the O limb. The weight bearing on the O limb was lower during static trial than during three-point crutch gait.

    Opis:
    A case is presented of mucormycosis in a patient with acute myeloblastic leukemia following liver transplantation for Wilson’s disease. A 58-year-old female was admitted to the Department of Haematology with deterioration of her general condition, loss of appetite, tiredness and difficulty with mental contact for a few days. Blood and urine cultures for bacteria and fungus, galactomannan antigen were negative. Whole body computed tomography demonstrated bilateral hilar lymphadenopathy with necrotic lesions: splenomegaly with a hypodensive lesion 13 × 20 × 19 mm and lower pulmonary infiltrates suggested fungal etiology. Magnetic resonance imaging of the brain showed thickened meninges. Finally, mucormycosis was diagnosed. Treatment with amphotericin B lipid complex was started, resulting in an partial improvement of the general condition and decreased level of inflammatory markers. However, the patient’s condition continued to deteriorate, with sepsis etiology Escherichia coli, and despite the intensive managements she eventually died.

    Opis:
    Purpose: Patients with spasticity suffer not only from neurological problems but also from various dentistry problems due to spasticity of the jaw muscles. Measurements of motion in temporomandibular joints should reflect the amount of abnormal muscle tone of these muscles. The aim of this study was to find out if the measurements of temporomandibular joint movements performed with the ultrasound Zebris device are different in cerebral palsy patients than in healthy subjects; and to find out if the information on the degree of spasticity in the lower legs provided by the Wartenberg test could be used to predict the degree of spasticty in the jaw muscles. Method: Twenty five healthy subjects and 25 cerebral palsy patients participated in the study. Two types of measurements were performed: temporomandibular movements measured with Zebris device, and instrumented Wartenberg test. Results: The laterotrusion and opening movements are different in CP patients than in healthy subjects. Laterotrusion movement correlates with velocity measured during the Wartenberg test. Conclusion: This finding suggests that high spasticity in the lower legs could indicate jaw movement restrictions in CP patients.
