Postural Sway Measurement Using a Body-Worn Movement Sensor in Clinical Stroke Rehabilitation: Exploring Sensitivity to Change and Responsiveness.
Observational study in Physical therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
importanceDuring rehabilitation, the balance of a person with stroke is commonly monitored using the Berg Balance Scale and the Mini-Balance Evaluation Systems Test. These tests evaluate the ability to maintain balance in an upright position while performing tasks. Currently, clinical practice lacks an adequate assessment of balance impairments like the increased postural sway poststroke. Integrating postural sway measurement with a body-worn inertial measurement unit could offer clinicians an objective and rapid measurement method.
objectiveSensitivity to change and responsiveness of postural sway measurement during stroke rehabilitation were explored.
designA longitudinal study was conducted.
settingData were collected in 5 rehabilitation centers.
participants94 people with stroke were included in the study.
interventionSensitivity to change was evaluated by comparing the percentages of participants who exceeded the minimal detectable change for both the conventional and inertial measurement unit tests. Responsiveness was assessed through hypotheses testing, utilizing both a criterion approach (external criterion: a 5-point retrospective Global Rating of Change score) and a construct approach.
resultsAt discharge, only 3.2% to 23.9% of the participants showed genuine improvement (ie, had a lower postural sway) on the inertial measurement unit test, compared to 33% to 60% on the conventional tests. In total, 67.4% of the hypotheses were rejected.
conclusionsThe sensitivity to change and responsiveness of postural sway measurement in people with stroke are limited. Restoring balance to achieve functional independence is not necessarily dependent on, or associated with, the level of postural sway. At present, integrating postural sway measurement into clinical stroke rehabilitation seems to provide no added value for monitoring balance. RELEVANCE: A novel approach to balance assessment in clinical stroke rehabilitation was investigated. It was found that while most participants improved in terms of functionality and independence, only a small percentage exhibited a significant change in postural sway. Therefore, postural sway may not effectively serve as an indicator of improved movement quality. This insight is crucial for both researchers and clinicians involved in neurorehabilitation.
