Psychodynamic Personality Correlates of Creativity
1986
Publisher Summary Creativity as a concept evokes almost exclusively positive associations, ranging from flexibility of thought to originality, productivity, and the great cultural achievements in the history of mankind. These positive associations, together with the easy availability of individual examples that can be regarded as self-evident proofs of creativity, help counteract the absence of a generally accepted definition of creativity. One of the basic media between persons and external reality is perception. It carries an array of different functions. The fact that perception is not a completely objective mechanism provides the basis for its use as a central variable in theories of pe…
Supination control increases performance in sideward cutting movements in tennis.
2013
The objective of this study was to explore the effects of tennis shoe characteristics on performance during sideward cutting movements followed by direction changes. Five tennis players (age = 21.5 +/- 0.8 years, mass = 75.2 +/- 2.8 kg, and height = 1.78 +/- 0.05 m) participated in the study and 10 tennis shoes were tested. Several footwear mechanical parameters were analyzed: Shore A hardness, longitudinal and transverse flexibility, midsole height at heel, presence of heel counters, and weight. A force plate was used to measure the kinetic variables, and two video cameras were used to perform a three-dimensional photogrammetric analysis. Results revealed that subject-footwear interaction …
Evaluation of Cyclic Fatigue of Hyflex EDM, Twisted Files, and ProTaper Gold Manufactured with Different Processes: An In Vitro Study.
2021
Introduction. The main aims of root canal instrumentation are to provide an environment that will lead to healing and to provide a root canal shape that is comfortable to clean and seal. When working with rotary endodontic instruments, the most significant concerns are that the instrument might fracture in the root canal, thus affecting the treatment outcome. Hence, it is of immense importance to know which file systems have more cyclic fatigue resistance. Methodology. This study evaluated the effect of the curved segment length of the artificial canal (the arch), and the number of cycles necessary in fracture of Hyflex EDM, Twisted files, and ProTaper Gold were recorded. Sixty NiTi rotary …
Effect of cusp coverage and water storage on compressive strength of composite restorations of premolars
2018
Background The aim of this study was to assess the effect of cusp coverage and water storage on compressive strength of composite restorations. Material and Methods This in vitro experimental study was conducted on 40 extracted human maxillary premolar teeth, which were randomly divided into four groups of 10. Mesio-occluso-distal (MOD) cavities were prepared in all teeth. The thickness of composite for cusp coverage was 1.5 mm in groups 1 and 3 and 2.5 mm in groups 2 and 4. Compressive strength (CS) was measured after 24 hours in groups 1 and 2 and after six months of water storage in groups 3 and 4. Two-way ANOVA was used to statistically analyze the data. Results The mean and standard er…
Reliability of Y-Balance Test y Wight Bearing Lunge Test for the clinical-functional evolution of plantar fasciitis
2018
[Resumen] Objetivos: Los objetivos de nuestro estudio han sido determinar en pacientes con FP unilateral la fiabilidad intraobservador del instrumento Y- Balance Test (YBT) y la prueba Wight Bearing Lunge Test (WBLT) medida con el inclinómetro de un telefono movil inteligente. Métodos: Estudio transversal y observacional, realizado con 16 pacientes (9 mujeres y 7 hombres). Resultados: Los resultados obtenidos revelan una excelente fiabilidad relativa intraobservador. El YBT mostró un CCI de 0’946; mientras que las medidas con inclinómetro obtuvieron un CCI de 0’992. En el YBT se apreció una asociación de variables estadísticamente significativa en la dirección posteromedial (p=0’004) y en e…
Auditory and Cognitive Deficits Associated with Acquired Amusia after Stroke: A Magnetoencephalography and Neuropsychological Follow-Up Study
2010
Acquired amusia is a common disorder after damage to the middle cerebral artery (MCA) territory. However, its neurocognitive mechanisms, especially the relative contribution of perceptual and cognitive factors, are still unclear. We studied cognitive and auditory processing in the amusic brain by performing neuropsychological testing as well as magnetoencephalography (MEG) measurements of frequency and duration discrimination using magnetic mismatch negativity (MMNm) recordings. Fifty-three patients with a left (n = 24) or right (n = 29) hemisphere MCA stroke (MRI verified) were investigated 1 week, 3 months, and 6 months after the stroke. Amusia was evaluated using the Montreal Battery of …

Isolated superior oblique palsies with electrophysiologically documented brainstem lesions
2000
Over a 13.5-year period, we observed 10 patients with isolated superior oblique palsies in whom electrophysiological abnormalities indicated brainstem lesions. In 7 patients unilateral masseter reflex abnormalities were seen, and were located on the side of the superior oblique palsy in 2 patients and on the opposite side in 5 patients. Two patients had slowed gain of following eye movements to the side contralateral to the superior oblique palsy. Slowed adduction saccades in the eye contralateral to the superior oblique palsy were seen in 1 patient. Clinical improvement was frequently (in 7 of 10 patients) associated with improvement or normalization of electrophysiologic findings. Magneti…
17. Masseter reflex abnormalities with meso-diencephalic lesions
2012
different papers and some eponyms used to characterize a certain neurological state differ from the original description. Except for Wallenberg‘s syndrome, classical brainstem syndromes are rarely seen in clinical practice. Lacunar brainstem syndromes are the consequence of infarcts, which involve long tracts and spare intra-axial cranial nerve segments. This group includes pure motor or pure sensory stroke, dysarthriaclumsy hand syndrome, or ataxic hemiparesis. Such infarcts may also cause body lateropulsion with or without limb ataxia, internuclear ophthalmoplgia, skew-torsion sign, or ocular tilt reaction. Small deep infarcts, which solely affect certain nuclei, may be followed by horizo…
