Hautala, Tuomas & Hiltunen, Janne 2012. 5. ja 8. luokkalaisten koululaisten fyysinen toimintakyky: Sukupuolten ja luokka-asteiden väliset erot sekä testien väliset yhteydet fyysistä toimintakykyä mittaavissa testeissä. Liikuntatieteiden laitos, Jyväskylän yliopisto. Liikuntapedagogiikan pro gradu -tutkielma, 106 s. Tutkimuksemme tavoitteena oli selvittää, esiintyykö tyttöjen ja poikien tai viides- ja kahdeksasluokkalaisten oppilaiden testitulosten välillä eroja fyysistä toimintakykyä mittaavissa liikuntatesteissä. Lisäksi selvitimme, esiintyykö eri toimintakykytestien tulosten välillä yhteyksiä viides- ja kahdeksasluokkalaisilla tytöillä ja pojilla. Sukupuolieroja tarkastelimme erikseen vii…
Fyysiset ominaisuudet ja motoriset taidot urheilevilla 10-12 -vuotiailla tytöillä
2017
Poijärvi, I. & Sievänen, S. 2017. Fyysiset ominaisuudet ja motoriset taidot urheilevilla 10–12 -vuotiailla tytöillä. Liikuntatieteellinen tiedekunta, Jyväskylän yliopisto, liikuntapedagogiikan pro gradu –tutkielma, 104 s., 1 liite. Hyvät motoriset valmiudet ja fyysiset ominaisuudet helpottavat arjen selviytymisessä, liikunnallisen elämäntavan omaksumisessa sekä edistävät urheilulajien harjoittelua ja omassa urheilulajissa menestymistä. Tässä tutkimuksessa oli tarkoituksena tutkia lajiharjoittelun ja taustamuuttujien yhteyttä motorisiin taitoihin ja fyysisiin ominaisuuksiin, lajien välisten tulosten vertailua sekä taito- ja ominaisuustestien yhteyksiä.

Motion detection in goldfish investigated with the optomotor response is “color blind”
1996
AbstractThe action spectrum of the optomotor response in goldfish was measured to investigate which of the four cone types involved in color vision contributes to motion detection. In the dark-adapted state, the action spectrum showed a single maximum in the range of 500–520 nm, and resembled the rod spectral sensitivity function. Surprisingly, the action spectrum measured in the light-adapted state also revealed a single maximum only, located in the long wavelength range between 620 and 660 nm. A comparison with spectral sensitivity functions of the four cone types suggests that motion detection is dominated by the L-cone type. Using a two colored, “red-green” cylinder illuminated with two…
Teprotumumab reduces extraocular muscle and orbital fat volume in thyroid eye disease
2020
PurposeThyroid eye disease (TED) is a progressive, debilitating and potentially vision-threatening autoimmune disease. Teprotumumab, a novel human monoclonal antibody, has been shown to reverse the clinical manifestations of TED. Patients receiving teprotumumab have been shown in two multicenter, randomized placebo-controlled trials to have decreased proptosis, diplopia and inflammation after 24 weeks of treatment. This study aims to analyse volumetric and inflammatory changes on orbital imaging prior to and after teprotumumab treatment from one of these trials.DesignRetrospective review.SubjectsSix patients enrolled in the phase III teprotumumab clinical trial (OPTIC, NCT03298867) with act…
Socioecological correlates of perceived motor competence in 5- to 7-year-old Finnish children
2019
We investigated child, family, and environmental factors associated with young children’s perceptions of locomotor (LM) and object control (OC) skills. The participants comprised 472 children (6.22 ± 0.63) and their parents. The children were assessed for their perception of motor competence in LM and OC skills (using the pictorial scale of Perceived Movement Skill Competence for young children), and actual motor competence (Test of Gross Motor Development 3rd edition and Körperkoordinationstest Für Kinder). Anthropometrics were calculated using the children’s body mass index standard deviation scores. A parent questionnaire included questions about child factors (sex, child’s independent w…
The Internuclear Ophthalmoplegias
1993
Internuclear ophthalmoplegia (INO), which is caused by an ipsilateral medial longitudinal fasciculus (MLF) lesion, is characterized by adduction paresis of lateral gaze, usually with spared convergence [1–4]. In the opposite eye, abduction nystagmus and hypermetric abduction saccades are the main clinical and electro-oculographic abnormalities [1, 5, 6]. The origin of both is still debated. Abduction nystagmus has been explained by (a) an additional horizontal gaze paresis [7]; (b) vergence mechanisms aimed at alignment of the visual axes [8]; (c) interruption of descending excitatory projections from oculomotor nucleus internuclear neurons to contralateral abducens nucleus motoneurons [9];…
Simple Configuration Effects on Eye Movements in Horizontal Scanning Tasks
2015
When reading text, observers alternate periods of stable gaze (fixations) and shifts of gaze (saccades). An important debate in the literature concerns the processes that drive the control of these eye movements. Past studies using strings of letters rather than meaningful text ('z-reading') suggest that eye movement control during reading is, to a large extent, controlled by low-level image properties. These studies, however, have failed to take into account perceptual grouping processes that could drive these low-level effects. We here study the role of various grouping factors in horizontal scanning eye movements, and compare these to reading meaningful text. The results show that sequen…
Magnetic stimulation in the definition of eloquent cortical areas
2003
Publisher Summary This chapter discusses the physiological principles of transcranial magnetic stimulation (TMS) and focus on detailing the techniques used in TMS mapping of the motor cortex relating it to the use of TMS in the presurgical assessment of patients with epilepsy. Since the main measure of TMS is the motor potential evoked in muscles, fine delineation of the functional topography of cortex is limited mainly to the primary sensorimotor cortex. In addition, TMS might be helpful to identify language dominance. The characterization of eloquent cortical areas is important in epilepsy surgery for the planning of the resection. TMS is not routinely employed for this purpose and TMS ma…
