The aim of this study was to evaluate the within-day and day-to-day agreement and reliability of the Six-Spot Step Test in mild to moderately disabled people with Parkinson's disease. Cross-sectional cohort study. Outpatient clinics. Forty-four people with Parkinson's disease. The Six-Spot Step Test was completed twice on day 1. Two days later, the Six-Spot Step Test was completed again. The agreement was estimated by Bland-Altman statistics with 95% limits of agreement, and reliability was estimated by the intraclass correlation coefficient. Subjects had a mean (SD) age of 67.8 (6.8) years, a median (range) Hoehn and Yahr score of 2.5 (1-4) and a mean (SD) Six-Spot Step Test score of 8.1 (1.8), 7.6 (1.7) and 7.6 (1.6) seconds on test occasions 1 to 3. An agreement for within-day and day-to-day of ±1.8 (±23.7%) and ±2.2 (±26.7%) seconds was found, respectively. The reliability was 0.81 and 0.76 within-day and day-to-day, respectively. A small learning effect was observed ( P < 0.05) between the first and second Six-Spot Step Test, but there was no learning between the second and third occasions. The Six-Spot Step Test has an acceptable within-day and day-to-day agreement and reliability in mild to moderately disabled people with Parkinson's disease. A change of 2.2 seconds can be regarded as a true change. To minimize learning effects, test trials of the Six-Spot Step Test are recommended before use.

D010300	Parkinson Disease	A progressive, degenerative neurologic disease characterized by a TREMOR that is maximal at rest, retropulsion (i.e. a tendency to fall backwards), rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. LEWY BODIES are present in the substantia nigra and locus coeruleus but may also be found in a related condition (LEWY BODY DISEASE, DIFFUSE) characterized by dementia in combination with varying degrees of parkinsonism.
