Table 5_Cross-sectional comparison of lower-limb muscle strength and contractile properties according to Parkinson’s disease and sarcopenia status.docx

This cross-sectional dataset compares lower-limb isometric strength and tensiomyography-derived contractile properties between 60 older adults (20 with Parkinson's disease and 40 age-matched healthy controls). It includes measurements of isometric strength across eight major lower limb movements and contractile properties for four muscles. The data offers insights into neuromuscular differences between Parkinson's disease and sarcopenia.

Use Cases

• Compare isometric muscle strength across eight lower limb movements between Parkinson's disease patients and healthy controls.
• Analyze tensiomyography-derived contractile properties, such as contraction time (Tc) and maximal displacement (Dm), for the lateral gastrocnemius, medial gastrocnemius, soleus, and tibialis anterior muscles.
• Investigate the relationship between sarcopenia status and peak isometric strength in specific tasks like hip extension and knee extension.
• Examine potential differences in neuromuscular patterns by comparing contraction time and maximal displacement data across participant groups.

Strengths

• Includes data from 60 older adults aged 58–85 years, with a defined cohort of 20 Parkinson's disease patients and 40 age-matched controls.
• Assesses muscle function using two methods: isometric strength across eight lower limb movements and tensiomyography for four specific muscles.
• Provides specific quantitative findings, such as a 23.6% increase in contraction time (Tc) and a 17.8% decrease in maximal displacement (Dm) in the lateral gastrocnemius for Parkinson's disease patients.

Limitations

• Small sample size of 60 participants limits statistical power and generalizability of findings.
• Cross-sectional design prevents establishing causal relationships between conditions and muscle properties.
• Data is presented in a DOCX document (25.7 KB), not a structured tabular format, which complicates direct computational analysis.
