minimal important change for the Visual Analogue Scale foot and ankle vas fa
Foot and Ankle Surgery, 2021Co-Authors: Antti J Saarinen, Martinus Richter, Mikko M Uimonen, Henrik Sandelin, Alar Toom, Jussi P RepoAbstract:Abstract Background Visual Analogue Scale foot and ankle (VAS-FA) is a patient-reported outcome measure for foot and ankle disorders. The VAS-FA is validated into several languages and well adopted into use. Nonetheless, minimal important change (MIC) for the VAS-FA has not been estimated thus far. Methods The VAS-FA score was obtained from 106 patients undergoing surgery for various foot and ankle complaints. MIC was estimated using an anchor-based predictive method. Results The adjusted MIC was 6.8 for total VAS-FA score, and 9.3 for the Pain, 5.8 for the Function, and 5.7 for the Other complaints subScales. The VAS-FA score was found to separate improvement and deterioration in patients’ foot and ankle condition. Conclusions MIC was successfully defined for the VAS-FA in the current study. The VAS-FA can be used to evaluate foot and ankle patients’ clinical foot and ankle status and its change. Further research on estimating disease-specific MICs is recommended.

normative data of the Visual Analogue Scale foot and ankle vas fa for pathological conditions
Foot and Ankle Surgery, 2011Co-Authors: Jens Stuber, Stefan Zech, Raymund Bay, Abdelrhahman Qazzaz, Martinus RichterAbstract:Abstract Background The purpose of this study was to analyze the Visual Analogue Scale Foot and Ankle (VAS FA) in patients to obtain normative data for pathological conditions. Methods The VAS FA was consecutively obtained in a foot and ankle outpatient clinic. The score results were categorized into different pathological foot and ankle conditions. Results 414 patients were evaluated. Overall scores and score categories of all pathology groups differed from non-pathological data ( n =121). Within the different groups, no score differences occurred. Score standards were defined for these groups with sufficient statistical power (>.8): isolated Hallux valgus, Hallux valgus and claw toes, forefoot other pathology, midfoot other pathology, hindfoot pathology and ankle deformity. No standards were defined for other pathology groups. Conclusions The obtained data is normative for different pathological conditions of the earlier validated VAS FA. The obtained data is normative for different pathological conditions of the earlier validated VAS FA. This data could serve as a basis for assessment patient scoring before, during and after treatment which has to then to be proved by ongoing research.

a new foot and ankle outcome score questionnaire based subjective Visual Analogue Scale validated and computerized
Foot and Ankle Surgery, 2006Co-Authors: Martinus Richter, Stefan Zech, J Geerling, Michael Frink, Karsten Knobloch, Christian KrettekAbstract:Abstract Our purpose was to construct and validate a new score taking into consideration the flaws of existing scores. Methods A new score named Visual-Analogue-Scale Foot and Ankle (VAS FA) with the following features was constructed: questionnaire based on 20 subjective questions, Visual-Analogue-Scale (VAS) based rating, computerized evaluation. The score was validated in 121 subjects. For validation, SF-36 ® and Hannover Questionnaire (Q) were obtained and correlated with VAS FA. Results The correlation VAS FA versus SF-36 ® and Q (Pearson, all p -values r ≥0.5) was sufficient for the total score and all score categories (pain, function, other complaints). The time needed for evaluating the scores was significantly lower for VAS FA than for SF-36 ® and Q (Oneway-ANOVA, p Conclusions The introduced score is the first validated (on SF-36 ® ), subjective, VAS based outcome score for foot and ankle. The VAS FA is computerized which enables faster evaluation than SF-36 ® or Q.

evaluation of gastrointestinal symptoms in different patient groups using the Visual Analogue Scale for irritable bowel syndrome vas ibs
BMC Gastroenterology, 2011Co-Authors: Mariette Bengtsson, Oskar Hammar, Thomas Mandl, Bodil OhlssonAbstract:Background Irritable bowel syndrome (IBS) and gastrointestinal (GI) dysmotility disorders have a similar clinical picture, although dysmotility disorders require the attention of a specialist. Patients with primary Sjogren's syndrome (pSS) have also been described to suffer from IBS-like symptoms. No objective marker is available to distinguish between the patients. A Visual Analogue Scale has been developed for IBS patients (VAS-IBS) to measure treatment response of GI symptoms and well-being in patients with IBS. The aim of the present study was to examine if VAS-IBS could be used to compare the degree of GI complaints in different patient populations, to get an objective marker to differentiate between the patients.

Development and psychometric testing of the Visual Analogue Scale for Irritable Bowel Syndrome (VAS-IBS)
BMC gastroenterology, 2007Co-Authors: Mariette Bengtsson, Bodil Ohlsson, Kerstin UlanderAbstract:Background The aim of this study was to develop and psychometrically test a short, patient-reported questionnaire to be used in clinical practice for patients with Irritable Bowel Syndrome (IBS). The Visual Analogue Scale for Irritable Bowel Syndrome (VAS-IBS) questionnaire was designed to measure the treatment response of symptoms and well-being in patients suffering from IBS.

reliability and validity of the finnish version of the Visual Analogue Scale foot and ankle vas fa
Foot and Ankle Surgery, 2017Co-Authors: Jussi P Repo, Erkki Tukiainen, Risto P Roine, Hannu Kautiainen, Jan Lindahl, Outi Ilves, Salme Jarvenpaa, Arja HakkinenAbstract:Abstract Background There have previously been no validated foot and ankle-specific patient-reported outcome measures in Finnish. Methods The Visual Analogue Scale Foot and Ankle (VAS-FA) was translated and adapted into Finnish. Thereafter, 165 patients who had undergone foot and ankle surgery completed a questionnaire set on two separate occasions. Analyses included testing of floor-ceiling effect, internal consistency, reproducibility, and validity. Results Minor linguistic differences emerged during the translation. Some structural adjustments were made. The mean (SD) total VAS-FA score was 74 (23). In the three subScales, maximum scores were noted in 2–5% of the responses, and internal consistency ranged from 0.81 to 0.94. Reproducibility was excellent (ICC, 0.97). The total VAS-FA score correlated significantly with the Lower Extremity Functional Scale ( r =0.84) and the 15D Mobility dimension ( r =0.79). The VAS-FA loaded on two factors (pain/movement and problems/limitations). Conclusions The Finnish version of the VAS-FA has high reliability and strong validity.
