Three methods for perceptual rating of audio stimuli were compared. The Visual Analogue Scale, VAS, was implemented as two computer programs and compared to the VAS on paper. The first program is a straight-forward implementation, the second program introduces the Visual Sort and Rate method, VSR. VSR allows the subject to compare stimuli of similar rating to each other, thus making the orderin...

BACKGROUND Clinicians increasingly require short, efficient methods for assessing distress, both in applied research and clinical settings. Most of the available questionnaires are unsuitable for busy clinical settings. The visual analogue scale (VAS) is widely but empirically used to assess perceived stress. AIMS To provide evidence on two of the psychometric properties of the VAS: its discr...

Reproducibility along a vertical 10 cm visual analogue scale (VAS) was investigated. Eight normal volunteers attempted to duplicate a set of marked VAS. There was a tendency to estimate too high on the scale, and reproducibility was found to be variable along its length. This indicates that the error involved in the use of VASs is even more complex than previously thought.

background health-related quality of life (hrqol) is used as a measure to valuate healthcare interventions and guide policy making. the euroqol eq-5d is a widely used generic preference-based instrument to measure health-related quality of life. objectives the objective of this study was to develop a value set of the eq-5d health states for an iranian population. patients and methods this study...

patients and methods fifty nine patients with indication for carpal tunnel release randomly assigned into two groups: open (n=30) or knifelight (n=29). the patients compared regarding scar length, operation duration, time to return to daily activities and amount of pain at three weeks after operation based on visual analog scale. results there was no significant differences regarding age and se...

Objectives: The aims of this study were to evaluate the efficacy of conservative treatment in patients with and without cervical ribs and Thoracic Outlet Syndrome (TOS). From so many kinds of conservative treatment in literature, we used a multidisciplinary approach (correction of posture, maximizing muscle endurance and power, stretch shorten muscles, massage for trigger points and maximize th...
