A case in point is item 9, where patients with a total ICARS between 45 and 65 points can present with either minimum or maximum scores i. Psychometric scaling analysis shows generally favourable properties for the total scale, but the subscale grouping could be improved.

A study of four rating scales. The study further provides predicted rate of changes of the ICARS separated for patients with early and late disease onset as well as for patients with different disease duration i.

To determine this, we would needed if it is to be considered as a primary outcome need to compare the measurement properties of the IC- measure for clinical trials.

Likewise, we did not detect any obvious difference in the rate of change according to the geographical region from which patients were recruited Europe: Thomas Klockgether The Lancet.

This study was supported by the Na- This study has several limitations. Consequently, the validity of the ICARS why we would be cautious to propose ataxai from our data is the extent to which it represents ataxia severity mea- set alone. To test for internal consistency, correlations of items within subscales and also between subscales were calculated using standard least squares linear regression.

However, individual scale items were prone to considerable floor and ceiling effects. However, the magnitude of item— suggesting the subscales measured related but different own-subscale to item— other-subscale differences varied constructs.

Thereafter, the posture and gait disturbances subscale and lower limb items of the kinetic functions subscale have reached a ceiling, and only fine motor skills, speech and ocular items contributed to further decline.

Balance assessment in multiple sclerosis and cerebellar ataxia: Icsrs scores are summed to give a total score Received 29 November ; Revised 24 March ; Accepted 15 ranging from 0 to There are patients represented in A whereas disease duration data were available for only patients in B.

The scale is made up of 8 items related to gait, stance, sitting, speech, finger-chase test, nose-finger test, fast alternating movements and heel-shin test. However, a detailed understanding of the dynamic range of each of the ICARS subscales and items might provide the basis for meaningful interpretations of study data.

That is usually the journal article where the information was first stated. J App Psychol ; The highest item-own-remainder subscale correlation of 0.

Development of a brief ataxia rating scale (BARS) based on a modified form of the ICARS.

Although total ICARS fulfils basic criteria for summated rating scales Spector,the grouping of items in subscales in the current version of the scale appears more problematic.

Overall, these results provided further preliminary coupled with the high test—retest correlations and that evidence of the weakness of the KF, SD, and OD scales, FDRA is a progressive neurological disease, suggest that as they failed to reach criteria for acceptable reliability the ICARS is unable to detect change.
