External focus strategy improves visuomotor control of gait in older adults.
Trial report in Psychological research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeFew studies have adopted external focus strategies to mitigate the negative effects of conscious movement processing in older adults. We investigated whether a single-session intervention (SSI) using an external focus could improve gait stability and visual search behaviors during adaptive locomotion in older adults.
methodsWe randomly allocated 112 older adults to either an external focus (EXT, n = 56) or a control group (CON, n = 56). Participants performed an obstacle circumvention walking task along an 8-m walkway for five trials at pre-intervention (T0), post-intervention (T1), and retention (T2). The training phase consisted of 20 walking trials with obstacle circumvention. EXT focused on digits displayed on monitors at their path destinations during walking, while CON walked naturally without any specific instructions. Gait kinematics (i.e., gait variabilities and body sway) and visual search data were collected at T0, T1, and T2.
resultsOnly EXT reduced body sway and variability of spatial and temporal gait parameters, while increasing gait speed when comparing T1 and T2 to T0. EXT also reduced the number of visual fixation and fixation duration percentage on the ground while increasing fixation duration percentage on the destination when comparing T1 and T2 to T0.
conclusionsThis study is the first to explore SSI with an external focus in older adults, providing evidence of significant improvements in gait stability and visual search behaviors that facilitate feedforward planning. Practicing with an external focus strategy could be recommended as an adjunctive psychomotor approach in clinical settings to enhance visuomotor performance in older adults.
