Filter by:Movement screening tests to identify deficits or poor movement quality is commonly used in soccer and other sports to assess injury, to evaluate rehabilitation goals and return to sport after injury. Female soccer players have an increased risk of suffering a knee injury which can be related to a poor knee control. Knee control can be observed and assessed by the Single Leg Squat (SLS) test. The SLS test is reported to be reliable, but there still is an overall lack of clear evidence of the accuracy for tests used for assessing movement quality in sports medicine, and the discriminate and predictive validity of the SLS test in a female soccer cohort needs to be further investigated. It is also not clear what significance other physiological- psychosocial- and hormonal factors have for the outcome of the SLS and for injury. The overall aim of this project is to investigate if the outcome of a visually assessed SLS test can discriminate between individuals with a previous injury in the lower extremity, and if the outcome, separate or together with physiological-, psychosocial- and hormonal factors can predict future injury in a cohort of female soccer players. The authors hypothesises that the outcome of the SLS cannot discriminate between individuals with a previous injury in the lower extremity but that the outcome of the SLS, separate or together with physiological-, psychosocial- and hormonal factors can predict future injury in a cohort of female soccer players. 269 female soccer players (≥16 Yr.) from Damallsvenskan, Elitettan and division 1 in the area of Stockholm was enrolled in the study and baseline measurements were done during 2022-01-08 to 2022-02-21. The female soccer cohort will be followed during the season 2022 regarding injuries upcoming injuries.
The satisfactory recovery of the patient after a surgery with an anesthetic request is very important for a quality and excellence assistance. The quality of recovery questionnaire QoR-15 was validated by their authors in 2013 with the study titled development and psychometric evaluation of a postoperative quality of recovery score: the QoR-15. This questionnaire allows a comprehensive assessment by associating the physiological parameters until then assessed with the subjective personal perception of the patient of his state of health. With the consent of its original author, this study is carried out to validate the questionnaire in Spanish and adapted to our environment.
Height may be used to calculate body mass index and reference interval for normal lung function, together with serving as an indicator for possible vertebral fractures in osteoporosis and growth retardation in children. Height is typically measured using the "gold standard" a fixed stadiometer in a clinical setting. However, newer studies have investigated alternative ways of measuring height using portable measuring devices with laser distance metres. The advantage with this type of measure is the ability to potentially perform reliable measure in settings outside clinical controlled settings. Recently, a measuring device which required adjustments of measuring axes by hand was developed, which resulted in a measurement error of 0.35 cm compared with 0.20-0.30 cm in fixed stadiometers. In order to optimise this, it was suggested that future measuring devices using laser distance meters should be fixed in one or more measurement axes. Thus, a novel portable height device, which is fixated in two axes using a laser distance metre has been developed.
Reliability of isokinetic strength measurement of the knee in typically developing children has yet been studied and seems to be good. Because in daily life activities strength of the hip- and ankle-joint muscles are also important, the investigators aim to study the reliability and validity of isokinetic strength measurements of the hip and ankle.
The study considers a cross-validation approach to determine the effectiveness of a non-invasive comprehensive metabolic panel (NICMP), relative to the venipuncture method. The NICMP machine learned powered device utilizes a light sensor to capture readings from either palm. The study (n=90) proves an agreement and strong correlation with respect to the NICMP and venipuncture blood draw.
The aim of this study is to assess the reproducibility over time of functional and structural magnetic resonance imaging, as well as specific biomarkers in plasma in healthy volunteers before and after a two-hour rest. This design mimics the timing of repeated scans and blood sampling before and after two hours of anaesthesia in subsequent substudies of the protocol, 'Neuroplasticity Induced by General Anaesthesia'.
Binocular vision tests are guided by the principle that uniform motion and focus of the eyes may be trained, but exercising the simultaneous movement of the pupils is necessary and important in achieving optimal and lasting results (Horwood & Toor, 2014). These tests have been in use for over 70 years and represent the foundation of therapy for visual deficiencies such as the inability of the eyes to move together. Despite their frequent use, no one has ever formally evaluated how good these tests are. One such evaluation method is reliability. A reliable test is one that will give the same result when repeated on multiple occasions (i.e. test-retest reliability) or by different people (inter-rater reliability). An unreliable test gives widely varying results when repeated, which would make changes in a patient's test results difficult to interpret. Therefore, this study aims to determine the test-retest reliability of seven binocular vision tests across two independent measurements. The investigators will measure 20 healthy people ages 18 to 35 years for each of these tests on two separate occasions, one week apart. Since these tests have been in use for many years, we are expecting the two measurements to be within acceptable range of each other. The tests being investigated measure: 3D vision (i.e. gross stereoscopic acuity), uniform movement of the eyes (i.e. "motor punctum proximum"), ability of the eyes to adapt to a target moving towards and/or away from the eyes (i.e. binocular fusion with convergence and divergence), quick movements of the eyes (i.e. saccadic movements), natural alignment of the eyes (i.e. anatomic oculomotor deviation), and double vision as a target is moved towards the eyes (i.e. convergence fusional proximum). The results of each test will be analyzed individually. If the tests are perfectly reliable, we would expect the results of the first test to equal the results of the second test for each participant. To examine the test-retest reliability the difference between the first and second test for each individual and across all individuals' scores summed together will be assessed.
Nasal lavage could be an integral component of assessing airway inflammation. Research into the reproducibility of cell counts is key to understanding the value of lavage results. The objective of this study is to evaluate and compare the reproducibility of a common nasal lavage technique and its variation in a sample of subjects with nasal symptoms (e.g. runny nose, congestion, sneezing, post nasal drip), and in individuals without nasal symptoms.
