Journal of Sports Science and Medicine , 2007,
Abstract: The purpose of the research was to study the repeatability of electromyographic (EMG) waveforms of major lower limb muscles during the naeryo chagi (axe kick) in taekwondo. Six male and female athletes, aged between 20 and 24 years served as volunteers. All participants were black belt holders and performed the naeryo chagi with their right leg. The electromyographic activity of rectus femoris, biceps femoris, gastrocnemius lateralis and tibialis anterior was recorded during the kick through four preamplified surface electrodes. The participants preformed 10 successive kicks to a fixed target with 1 min inter-trial interval. The electromyograms were recorded during each kick at a sampling frequency of 1000Hz. After the processing of the raw EMG data, myoelectrical activity was normalized on the time and amplitude domain. The coefficient of variation (CV), intra-class correlation coefficient (ICC) and coefficient of multiple correlation (CMC) were computed to test the repeatability of the electromyographic waveforms in each participant. The electromyographic activity during the naeryo chagi demonstrated poor repeatability. More specifically, all CVs were greater than 80%, all CMCs were lower than 0.75 and the majority of the average measure ICCs as well as all single measure ICCs were lower than 0.55. It seemed that only ensemble averages of EMG waveforms obtained from more than ten kicks may be considered as representatives of the muscle function in naeryo chagi and conclusions that have been drawn from a single trial should be reconsidered

Abstract: We describe the effects of an exercise programme based on the American Heart Association and American Stroke Association guidelines for stroke patients on gait mechanics in a patient with severe gait disorder due to chronic ischaemic stroke. A 74-year-old female patient, with right hemiparesis as a result of a stroke attack before 18 months followed an 8-week exercise programme, consisting of three hourly sessions per week. Patient’s gait mechanics were evaluated before and after the intervention using a three-dimensional gait analysis system, with six infrared cameras, two force plates, and an electronic timing system. Exercise led to increase of spatial and decrease of temporal gait parameters, increase of joint range of motion and lower limb muscle powers during the entire gait cycle and increase of the moments in the support phase. In conclusion, exercise had a positive effect on this patient’s gait pattern and improved her functionality.

Abstract: Introduction :?In 2014, American Heart Association and American Stroke Association (AHA/ASA) issued exercise guidelines for stroke patients. Aim of the Study: To study the effects of an exercise programme based on AHA/ ASA guidelines, on gait kinematics and kinetics in patients with chronic ischemic stroke. Materials and Methods: Twelve stroke patients, 67.33 ± 9.14 years old, followed an 8-week exercise programme, with 3 hourly sessions per week, consisting of strength, endurance and flexibility training, as well as neuromuscular activities. Patients’ gait kinematics and kinetics were evaluated before and after the intervention using a 3-dimensional gait analysis system. Results: In most cases, patients in the intervention group showed significant increase or no change in gait kinematics, significant increase in joint moments at the anterior-posterior plane during support phase, and non-signi- ficant change in the frontal and transverse planes kinetics. Conclusions: Exercise prevented further deterioration and/or led to improved walking pattern.

Abstract: 39 bullous pemphigoid (BP) patients were studied to assess the clinical significance of anti-BP180 and anti-BP230 circulating autoantibodies of BP and correlate their titers with the clinical scores of the BP Disease Area Index (BPDAI) and the Autoimmune Bullous Skin Disorder Intensity Score (ABSIS) as well as with the intensity of pruritus measured by the BPDAI pruritus component. All parameters were evaluated by the time of diagnosis (baseline), month 3, and month 6. Titers of anti-BP180 autoantibodies were strongly correlated with BPDAI (, ) and ABSIS (, ) values, as well as with BPDAI component for the intensity of pruritus (, ) at baseline. At month 3, titers of anti-BP180 autoantibodies were strongly correlated with BPDAI (, ) and ABSIS (, ) values, as well as with the BPDAI component for the intensity of pruritus (, ). At month 6, titers of anti-BP180 autoantibodies were strongly correlated with BPDAI (, ) and ABSIS (, ) values, as well as with the BPDAI component for the intensity of pruritus (, ). There was no statistically significant correlation between titers of anti-BP230 autoantibodies and the BPDAI, ABSIS, and BPDAI component for the intensity of pruritus at the same time points.

Abstract: We examined 25 patients with OCD and 25 healthy controls, matched by age, education, and gender. We administered Penn's Humor Appreciation Test (PHAT), a computerized test comprising captionless cartoons by Mordillo. Each set of stimuli consisted of two almost identical drawings, one of which was funny due to the alteration of a detail in the cartoon, whereas the other was not funny. Severity of psychopathology was evaluated with the Yale-Brown Obsessive Compulsive Scale (Y-BOCS).No significant effect for group, gender or group × gender interaction was found on the PHAT scores. In OCD patients, humor appreciation was not significantly associated with age of onset, duration of illness, and obsessions, but correlated significantly with compulsions.Humor appreciation, based on captionless cartoons in OCD, does not seem to be deficient compared to healthy subjects but may be related to illness characteristics.Data from structural and functional imaging studies in obsessive-compulsive disorder (OCD) have suggested abnormalities in the orbitofrontal cortex, anterior cingulate, caudate, and thalamus, structures linked by well described neuroanatomic circuits [1,2]. Findings of previous studies addressing neuropsychological functioning in patients with OCD, however, have not presented a clear and specific neuropsychological profile for these patients. There is some evidence for visuospatial and verbal memory dysfunction in OCD, owing to an underlying executive deficit in the ability to organize necessary strategies to encode the presented information [3,4]. Mean effect sizes on fluency, set shifting, planning, and problem solving abilities point to large overall differences between OCD patients and healthy controls, indicating poorer performance in patients [3,4]. With regard to attention, some aspects such as attention span, sustained attention, and selective attention seem to be unaffected, whereas speed of information processing was impaired in about half of the studies.
