Effect of Cerebellar Stimulation on Postural Control in Chronic Ankle Instability

A 2026 study by Shanshan Zheng on figshare presents results from a randomized, sham-controlled laboratory trial with 22 participants. It examines the immediate effects of a single session of cerebellar transcranial direct current stimulation on postural control and associated resting-state functional alterations in patients with chronic ankle instability. The dataset includes pre- and post-intervention assessments of center-of-pressure sway, Balance Error Scoring System scores, and functional MRI metrics.

Use Cases

• Analyze the effect of cerebellar tDCS on mediolateral postural sway based on center-of-pressure length data.
• Correlate changes in postural control with alterations in cerebellar activity based on regional homogeneity and amplitude of low-frequency fluctuations from fMRI.
• Compare laboratory-based CoP metrics with clinic-based BESS outcomes to assess sensitivity.
• Investigate the association between tDCS-induced postural changes and activity coherence in the cerebellar superior lobe 3.

Strengths

• Dataset is from a randomized, sham-controlled laboratory study, suggesting a controlled experimental design.
• Includes multiple assessment types: laboratory-based CoP sway, clinic-based BESS scores, and resting-state fMRI metrics.
• Results include specific statistical measures (p=0.020, Cohen's d=-0.963, r=-0.709).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (20.1 KB), indicating limited scope, likely containing summary results rather than raw participant-level data.
