Responsiveness to sensory cues using the Timed Up and Go test in patients with Parkinson's disease: A prospective cohort study

OBJECTIVE:To test the effectiveness of the Timed Up and Go (TUG) test to define responsiveness to auditory and visual cues in patients with Parkinson's disease.METHODS:Consecutive patients > 50 years old were enrolled if they were classified as stage 1-3 of the Hoehn and Yahr scale; scored ≤ 45 on part III of the Unified Parkinson's Disease Rating Scale; > 23 on the Mini-Mental State Examination; and were able to perform the TUG test without assistance. Within-subject analysis identified positive-responders, negative-responders and non-responders. TUG times with and without sensory cues were studied among all patients, and among responders only using the Friedman Test.RESULTS:Twenty-two patients (16 men, 6 women), mean age 72.4 years (standard deviation (SD) 8.7 years) were included. Basal mean TUG time was 12.3 (SD 4.0). TUG times after visual cues (11.7 (SD 4.8)) were lower than in basal conditions (p = 0.006), whereas TUG times after auditory cues were not (p > 0.05). In the 16 patients who were positive-responders, mean TUG times after visual (11.0 (SD 3.1)) and auditory (11.3 (SD 3.6)) cues were lower than in basal conditions (12.5 (SD 3.8)) (p = 0.0002).CONCLUSION:The TUG test may be used to tailor the rehabilitation programme in patients with Parkinson's disease, identifying those who respond to visual and auditory cueing.
