%X The aim of this study was to evaluate the concurrent and divergent validity of the Six-Spot Step Test in mild to moderately impaired people with Parkinson＊s disease. Cross-sectional cohort study. Outpatient clinics. Fifty-eight people with Parkinson＊s disease. The Six-Spot Step Test, the Timed ※Up and Go§ test, the mini-Balance Evaluation Systems Test (mini-BESTest), and postural sway were tested on the same day, and the Spearman＊s Rank Correlation Coefficient (老) was used for data analysis. Subjects had a median age of 68ˋyears (Q1每Q3: 62每73), a median Hoehn and Yahr score of 2.5 (Q1每Q3: 2每3), a median Six-Spot Step Test score of 7.9ˋseconds (Q1每Q3: 6.5每9.2), a median Timed ※Up and Go§ test score of 7.0ˋseconds (Q1每Q3: 5.6每7.9), a median mini-BESTest score of 22.5 (Q1每Q3: 19.8每25.0), and a median postural sway score of 27.9ˋmm2 (Q1每Q3: 15.0每53.5) and 22.5ˋmm/s (Q1每Q3: 14.6每39.8). Statistical significant correlations were found between the Six-Spot Step Test and the Timed ※Up and Go§ test (老ˋ=ˋ0.81) and the mini-BESTest (老ˋ=ˋ每0.64), whereas no significant relations were identified between the Six-Spot Step Test and postural sway (老ˋ=ˋ0.18, Pˋ>ˋ0.05). In patients with Parkinson＊s disease, the Six-Spot Step Test showed promising concurrent validity to other recommended clinical tests for encompassing balance capacity and capacity of functional mobility, making it a reasonable and easily administered alternative to existing assessment tools when measuring walking agility. As expected, weak correlates to postural sway revealed that the Six-Spot Step test is not a valid measure of standing balance
