Construct validity and reliability of the Finnish version of the Knee Injury and Osteoarthritis Outcome Score

2018

Background The Knee Injury and Osteoarthritis Outcome Score (KOOS) is a commonly used knee assessment and outcome tool in both clinical work and research. However, it has not been formally translated and validated in Finnish. The purpose of this study was to translate and culturally adapt the KOOS questionnaire into Finnish and to determine its validity and reliability among Finnish middle-aged patients with knee injuries. Methods KOOS was translated and culturally adapted from English into Finnish. Subsequently, 59 patients with knee injuries completed the Finnish version of KOOS, Western Ontario and McMaster Osteoarthritis Index (WOMAC), Short-Form 36 Health Survey (SF-36) and Numeric Pai…

Validity of five foot and ankle specific electronic patient-reported outcome (ePRO) instruments in patients undergoing elective orthopedic foot or an…

2019

Background: Patient-reported outcomes (PROS) are widely accepted measures for evaluating outcomes of surgical interventions. As patient-reported information is stored in electronic health records, it is essential that there are valid electronic PRO (ePRO) instruments available for clinicians and researchers. The aim of this study was to evaluate the validity of electronic versions of five widely used foot and ankle specific PRO instruments. Methods: Altogether 111 consecutive elective foot/ankle surgery patients were invited face-to-face to participate in this study. Patients completed electronic versions of the Foot and Ankle Ability Measure (FAAM), the Foot and Ankle Outcome Score (FAOS),…

Luokittelumenetelmän evaluointimenetelmien vertailu pienten aineistojen tapauksessa simulointikokein

2016

Luokitteluanalyysin tyypillinen ongelma on mallin valinta ja/tai muuttujien eli piirteiden valinta. Tavoitteena on estimoida luotettavasti luokitteluvirheen todennäköisyys opetusaineiston avulla - ideaalissa tilanteessa käyttäen riippumatonta testiaineistoa. Tällöin saadaan estimaatti yleistämisvirheelle, joka kuvaa opetusaineistosta estimoidun mallin kykyä ennustaa riippumatonta testiaineistoa. Usein kuitenkin aineiston niukkuudesta johtuen ei voida käyttää erillistä riippumatonta testiaineistoa, jolloin ei myöskään voida estimoida suoraan yleistämisvirhettä. Tällöin voidaan kuitenkin käyttää otoksen uudelleenkäyttömenetelmiä, joista käytetyimmät lienevät ristiinvalidointi ja bootstrap. Me…

Heart rate responses during the modified six-minute walk test among Special Olympics athletes

2021

Objective: The construct validity of the modified six-minute walk test (m6MWT) was examined by addressing the following questions: 1) do participants attain a steady state plateau in heart rate (HR) within the range of 110-150 beats per minute? 2) at what percentage of their predicted HR maximum were participants during each minute of the test? Material and Methods: Participants were 36 (male=56%) Special Olympics athletes aged 34.4 years (SD = 12.7). Following familiarization, participants completed the m6MWT while wearing a Polar Team 2 heart rate monitor. Results: By the end of the first minute, average heart rate was 120bpm, and a factorial repeated measures ANOVA revealed that steady s…

Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow score kyselylomakkeen adaptaatio ja validointi Suomeen

2021

Kerlan-Jobe Orthopaedic Clinic (KJOC) Shoulder and Elbow score -kyselylomake on Yhdysvalloissa kehitetty yli olan urheilijoiden olka- ja kyynärpään itsearvioidun toimintakyvyn työväline. Yli olan urheilulla tarkoitetaan lajeja, joissa yläraajaan kohdistuu toistuvaa kuormitusta hartiatasossa tai sen yläpuolella. Yläraajan vammat ovat kyseisissä lajeissa yleisiä ja luotettavat terveyden seurannan mittarit ovat merkittävä osa urheilijoiden hyvinvoinnin arviointia. KJOC-kysely sisältää esitieto-osion sekä kymmenen yläraajan toiminta- ja suorituskykyä tiedustelevaa kysymystä. Alkuperäinen englanninkielinen KJOC-kysely on osoittautunut päteväksi, toistettavaksi ja muutosherkäksi mittariksi, mutta…

Toolbox for Distance Estimation and Cluster Validation on Data With Missing Values

2022

Missing data are unavoidable in the real-world application of unsupervised machine learning, and their nonoptimal processing may decrease the quality of data-driven models. Imputation is a common remedy for missing values, but directly estimating expected distances have also emerged. Because treatment of missing values is rarely considered in clustering related tasks and distance metrics have a central role both in clustering and cluster validation, we developed a new toolbox that provides a wide range of algorithms for data preprocessing, distance estimation, clustering, and cluster validation in the presence of missing values. All these are core elements in any comprehensive cluster analy…

Species distributions models may predict accurately future distributions but poorly how distributions change: A critical perspective on model validat…

2023

Aim: Species distribution models (SDMs) are widely used to make predictions on how species distributions may change as a response to climatic change. To assess the reliability of those predictions, they need to be critically validated with respect to what they are used for. While ecologists are typically interested in how and where distributions will change, we argue that SDMs have seldom been evaluated in terms of their capacity to predict such change. Instead, typical retrospective validation methods estimate model's ability to predict to only one static time in future. Here, we apply two validation methods, one that predicts and evaluates a static pattern, while the other measures change…

Tumor-independent Detection of Inherited Mismatch Repair Deficiency for the Diagnosis of Lynch Syndrome with High Specificity and Sensitivity

2023

Lynch syndrome (LS) is the most common hereditary cancer syndrome. Early diagnosis improves prognosis and reduces health care costs, through existing cancer surveillance methods. The problem is finding and diagnosing the cancer predisposing genetic condition. The current workup involves a complex array of tests that combines family cancer history and clinical phenotypes with tumor characteristics and sequencing data, followed by a challenging task to interpret the found variant(s). On the basis of the knowledge that an inherited mismatch repair (MMR) deficiency is a hallmark of LS, we have developed and validated a functional MMR test, DiagMMR, that detects inherited MMR deficiency directly…
