Cerebellar tDCS Effects on Postural Control in Chronic Ankle Instability

A 2026 study by Shanshan Zheng on figshare presents data from a randomized, sham-controlled laboratory trial with 22 participants. It measures the immediate effects of a single session of cerebellar transcranial direct current stimulation on postural control and cerebellar resting-state activity in individuals 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 correlation between tDCS-induced postural changes and cerebellar activity coherence based on functional MRI metrics.
• Compare laboratory-based center-of-pressure sway outcomes with clinic-based Balance Error Scoring System outcomes.
• Model the effect size of cerebellar stimulation on mediolateral postural control based on reported Cohen's d values.

Strengths

• Dataset is from a randomized, sham-controlled study design, a gold standard for clinical trials.
• Includes multiple assessment modalities: biomechanical (CoP), clinical (BESS), and neuroimaging (fMRI).
• Specific statistical results are reported, such as p=0.020 and Cohen's d=-0.963 for a key outcome.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 25.2 KB file size suggests a very limited scope, likely containing summary results rather than raw participant-level data.
