WebOct 1, 2024 · The visual acuity score was determined by the total number of optotypes correctly identified. The following formula was used to transform scores to logMAR values: logMAR visual acuity score = 1.10 − 0.02T c. A value of 0.02 log units was assigned to each optotype identified, and T c was the total number of optotypes correctly identified. WebAbstract. Objectives: To assess balance, dynamic gait, and dynamic visual acuity outcomes after a vestibular and balance rehabilitation program and to determine which variables were significantly associated with improved balance and ambulation.
