The primary aim of this study was to assess the interrater reliability of the Dynamic Leap and Balance Test (DLBT) in chronic ankle instability (CAI) and healthy groups. The secondary aim was to assess the differences in errors and time taken to complete the DLBT between the two groups for both raters and to identify cutoff scores to distinguish between patients with CAI and healthy controls. This was a controlled laboratory reliability analysis study. Fourteen healthy college‐aged subjects (9 women 5 men; weight = 62.10 ± 8.03; height = 168.35 ± 6.0) and sixteen with a history of CAI (9 women, 7 men; weight = 68.01 ± 10.74; height = 172.08 ± 11.37) participated. Interrater reliability was determined by independent raters for both total time taken to complete the task and errors made. The most optimal score to discriminate between two groups was determined by receiver operator curve analysis. Total time taken and errors made were also documented for group differences as secondary analysis. A strong agreement was found between the two raters for time and errors with intraclass correlation coefficient >0.80. Significantly ( P < .05) higher number of errors were made and greater time taken by the CAI subjects when compared with healthy for both raters. The most optimal score to discriminate between CAI and healthy control was 43.28s and 4 errors. Excellent interrater reliability substantiates that it can be used confidently by different clinicians for testing dynamic balance. CAI group took more time and made more errors to complete the DLBT.
