Handgrip Strength and Cortical Hemodynamics in Patients with Stable Schizophrenia

A cross-sectional study of 96 long-term hospitalized patients with stable schizophrenia, with a median age of 52 years. The dataset contains measurements of handgrip strength phenotypes and functional near-infrared spectroscopy (fNIRS) metrics during a Verbal Fluency Task. It was authored by Yanping Feng and last updated on 2026-05-15.

Use Cases

• Correlating handgrip strength asymmetry with frontal lobe hemodynamic responses based on fNIRS metrics like S-integral.
• Evaluating handgrip strength as a potential surrogate marker for neurocognitive function in schizophrenia based on the study's objective.
• Building statistical models to adjust for confounders in neurophysiological associations using the described general linear models.

Strengths

• Includes data from 96 patients with detailed demographic breakdown (40.60% male, 59.40% female).
• Contains specific, derived fNIRS metrics such as S-integral, T-centroid, and K-activation from oxygenated and total hemoglobin signals.
• Dataset is openly licensed under CC-BY-4.0.

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 small in scale at 43.4 KB, indicating limited scope.
