“…Thus, many dynamic balance assessment tools have been developed, including clinical scales 5 , quantitative gait markers 6 , posturography 7 , fall prevention protocols 8 and single- and dual-task tests 9 . Regarding clinical scales, the Berg balance scale 10 , the MiniBESTest 10 , the timed up and go (TUG) 11 , and the modified dynamic gait index (mDGI) 12 , 13 are among the most commonly used in clinical practice to measure balance in PwND. Compared to the Berg scale, which does not assess dynamic balance during locomotion, and the TUG and MiniBESTest, which evaluate this aspect in a few functional tasks (i.e., one task in TUG and five tasks in MiniBESTest), the mDGI is specifically devoted to measuring an individual’s capacity to maintain their balance and adapt their gait in the presence of various environmental demands, essential to perform daily-life locomotor activities without falling.…”

“…The highest possible score on the mDGI is 64 points. The mDGI has been extensively validated in subjects with mobility impairments 14 , 15 and in different pathological cohorts such as stroke (ST), vestibular dysfunction, multiple sclerosis (MS), traumatic brain injuries, and Parkinson’s disease (PD) 12 , 13 . Recently, Torchio et al provided cut-off values to identify PwND with no or minimal risk of falls (mDGI score ) and PwND with high risk of falls (mDGI score ) 16 .…”

“…It is important to highlight that the PT group nearly reached a medium effect size and showed a minimal clinically important difference for the ABC scores (10.5%) for patient perceptions about their functional balance ability. A minimal clinically important difference of 10% for the ABC scores has been suggested for outpatients with neurological conditions (e.g., Parkinson’s disease, multiple sclerosis, and stroke) [ 30 ]. Our results suggest that a larger sample size would be needed to reach statistical significance despite the minimal clinical improvement of 10.5% on the ABC scores after the PT program.…”

“…Change in modified Dynamic Gait Index (mDGI): The modified Dynamic Gait Index is a clinical outcome measure to assess the ability to modify and adapt gait and balance during complex walking tasks. Higher scores indicate better performances [32].…”
