<b>Near-Infrared Spectroscopy Demonstrates Preserved and Reproducible Resting Skeletal Mus

Supplementary material from a study demonstrating preserved near-infrared spectroscopy (NIRS)-derived skeletal muscle oxygenation across five anatomical sites in patients with stable chronic heart failure. The 835.2 KB DOCX file, authored by Joanne Eng-Frost and last updated in June 2026, contains data supporting the reproducibility of NIRS measurements for longitudinal monitoring. The findings suggest resting oxygenation may have greater diagnostic value during physiological stress or acute decompensation.

Use Cases

• Validate the reproducibility of NIRS sensor measurements based on the described repositioning tests.
• Investigate microvascular abnormalities in chronic heart failure using the preserved resting oxygenation data.
• Develop diagnostic models for heart failure that incorporate physiological stress data, as suggested by the description.
• Compare skeletal muscle oxygenation patterns across different clinically accessible anatomical sites.

Strengths

• Data supports high measurement reproducibility following sensor repositioning, as stated in the description.
• Focus on five clinically accessible anatomical sites provides practical relevance for application.
• Dataset is openly shared under a CC-BY-4.0 license, facilitating reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 835.2 KB file size suggests a limited scope of data.
