Objective Analysis of Performance of Activities of Daily Living in XXXX With Central Field Loss.

@entity1 @entity227
Purpose: @entity1 with @entity227 ( @entity227 ) adopt various strategies to complete activities of daily living (ADL). Using objective movement analysis, we compared how three ADLs were completed by @entity1 with @entity227 compared with age-matched, visually healthy individuals. Methods: Fourteen @entity1 with @entity227 (age 81    10 years) and 10 age-matched, visually healthy (age 75    5 years) participated. Three ADLs were assessed: pick up food from a plate, pour liquid from a bottle, and insert a key in a lock. @entity1 with @entity227 completed each ADL habitually (as they would in their home). Data were compared with visually healthy @entity1 who were asked to complete the tasks as they would normally, but under specified experimental conditions. Movement kinematics were compared using three-dimension motion analysis (Vicon). Visual functions (distance and near acuities, contrast sensitivity, visual fields) were recorded. Results: All @entity227 @entity1 were able to complete each ADL. However, @entity1 with @entity227 demonstrated significantly (P < 0.05) longer overall movement times, shorter minimum viewing distance, and, for two of the three ADL tasks, needed more online corrections in the latter part of the movement. Conclusions: Results indicate that, despite the adoption of various habitual strategies, @entity1 with @entity227 still do not perform common daily living tasks as efficiently as healthy subjects. Although indices suggesting feed-forward planning are similar, they made more movement corrections and increased time for the latter portion of the action, indicating a more cautious/uncertain approach. Various kinematic indices correlated significantly to visual function parameters including @entity227 .
