Brief Summary:

The objectives of this study are:

  • To validate the inter-rater and intra-rater reliability of a new scale for the assessment of ataxia and neurologic dysfunction (STAND)
  • To assess common constructs and correlation between STAND subscale items.

Condition or disease Intervention/treatment
Spinocerebellar Ataxia - All Sub-types Friedreich's Ataxia Other: Ataxia rating scale

Detailed Description:
There are few validated, comprehensive rating scales for the assessment of ataxia severity. The development of a Scale To assess Ataxia and Neurologic Dysfunction (STAND) would examine and measure as many facets of ataxia as possible. Scale items to be measured include parkinsonism, timed gait analysis, dystonia, neuropathy and peripheral nerve weakness, as well as other areas of clinical manifestation for ataxia. This brief but thorough scale should yield a thorough measurement of ataxia.

Time Perspective: Prospective
Official Title: Preliminary Study of the Scale To Assess Ataxia and Neurologic Dysfunction (STAND)
Study Start Date : October 2012
Actual Primary Completion Date : June 2016
Actual Study Completion Date : June 2016

Group/Cohort Intervention/treatment
Subjects with Ataxia
Patients with a diagnosis of ataxia (Friedreich's ataxia or Spinocerebellar ataxia type 1-30) aged 18-80 years old will be recruited for the study.
Other: Ataxia rating scale
Administer new rating scale for ataxia. This will be administered by two different raters on two separate occassions, 4 to 6 weeks apart.

Primary Outcome Measures :
  1. Inter- and intra-rater agreement [ Time Frame: 4 to 6 weeks ]
    Assess agreement between raters (inter-rater agreement) and within raters (intra-rater agreement) through the evaluation of STAND total score, subtotals and individual variables using intraclass correlation coefficients (ICCs).
