OBJECTIVE: To develop and validate a clinical tool based on the biomechanical
strategies exhibited by people with hemiparesis due to stroke during the
performance of the Timed "Up and Go" test. DESIGN/METHODS: The Timed "Up and Go"
Assessment of Biomechanical Strategies (TUG-ABS) was developed for subjects with
stroke, based on the analyses of 3 sources of information: published evidence;
opinions of rehabilitation professionals; and observations of TUG performances,
followed by a multi-step approach, which involved the investigation of the
reliability, content, and criterion-related validity of the preliminary version.
Content validity was established by an expert panel, whereas intra- and
inter-rater reliability was established by two independent examiners.
Criterion-related validity was established by comparing the TUG-ABS scores at the
item level obtained by independent analyses of video observations and the gold
standard motion analysis system. The final tool included the items, which showed
acceptable values for these psychometric properties. RESULTS: The preliminary
version consisted of 24 items with 3 response categories. Twenty-one items showed
acceptable content validity (0.72 </= kappa </= 1.00; p </= 0.01), 19 acceptable
intra- and inter-rater reliability (0.36 </= kappa </=1.00; p </= 0.04), and 15
acceptable criterion-related validity (0.29 </= kappa </= 1.00; p </= 0.04).
CONCLUSION: The final developed 15-item TUG-ABS version proved to be valid and
reliable for individuals with hemiparesis due to stroke, but it should be
clinically validated before being used for clinical applications and research
purposes.
