Table 2 Descriptive statistics of recovery step and cognitive performance accuracy DTCs (Mean ± SEM). DTCs calculated according to Kelly et al. (2010). Note: positive DTC values indicate relative improvement in DT condition, while negative DTC values indicate worse performance in DT, relative to ST task performance. Abbreviations: Sit Sitting task condition, UPwDT Unperturbed walking condition with a concurrent cognitive task, PwDT Perturbed walking condition with a concurrent cognitive task

From: Balance recovery stepping responses during walking were not affected by a concurrent cognitive task among older adults
