The objectives of this study were to develop a functional outcome instrument for hip and knee osteoarthritis research (OA-FUNCTION-CAT) using item response theory (IRT) and computer adaptive test (CAT) methods and to assess its psychometric performance compared to the current standard in the field.
In this study, we developed a functional outcome instrument for hip and knee osteoarthritis research (OA-FUNCTION-CAT) using IRT and CAT methodologies and evaluated its psychometric performance compared with the full item bank and with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), the current standard in the field.
The content of the SMILI was devised by Mary Ross-Dande and the technical expertise to turn the content into a functional computerised instrument were provided by Kevin Swingler.
The recent development of molecularly imprinted polymers enables production of low cost and highly stable sensing chips; however, the commercially available and full functional instruments employed for electrochemical analysis have shortcomings in actual homecare applications.
The authors suggest as well the use of different measures to assess the intervention effects, as more functional instruments can capture 'hotter' aspects of the PIAFEx.
Therefore, 914 (100%) functional instruments were revised, 877 (96.0%) out of them were successfully recalibrated.
Thirty-nine percent of all facilities reported availability of functional instruments required for cataract diagnosis and follow-up (slit lamp, ophthalmoscope and retinoscope).
The objective of this study was to concurrently compare responsiveness and MCID for commonly used pain scales and functional instruments in four subpopulations of LBP patients.
Other functional instruments particularly used for patients with mild cognitive impairment are the Activities of Daily Living-Prevention Instrument [ 31], developed to rate ADL in prevention of dementia studies, and the Functional Assessment Questionnaire [ 32].
Other functional instruments used in different clinical settings for assessment of AD patients are the Interview for Deterioration in Daily Living Activities in Dementia [ 27], the Functional Autonomy Measurement System [ 28], and the Rapid Disability Rating Scale [ 29].
Further studies comparing inpatient and outpatient models, with more specific functional instruments and cost-effectiveness analysis, may guide the decision-making process toward rehabilitation strategies for neurologically impaired population.
