Table 4_Cross-sectional comparison of lower-limb muscle strength and contractile properties according to Parkinson’s disease and sarcopenia status.docx

Cross-sectional measurements from 60 older adults (20 with Parkinson's disease, 40 age-matched controls) aged 58–85 years. It compares isometric strength across eight lower-limb movements and tensiomyography-derived contractile properties for four muscles. The data was collected to analyze neuromuscular differences between Parkinson's disease and sarcopenia statuses.

Use Cases

• Compare isometric muscle strength in hip and knee extension tasks between sarcopenic and non-sarcopenic participants.
• Analyze the relationship between contraction time (Tc) and maximal muscle displacement (Dm) in the lateral gastrocnemius muscle for individuals with Parkinson's disease.
• Investigate differences in muscle contractile properties across the lateral gastrocnemius, medial gastrocnemius, soleus, and tibialis anterior muscles by disease and sarcopenia status.

Strengths

• Includes data from 60 participants with a defined age range of 58–85 years.
• Provides measurements for eight major lower-limb isometric strength movements and four specific muscles for contractile properties.
• Uses a controlled study design with 20 Parkinson's disease patients and 40 age-matched healthy controls.

Limitations

• Small sample size of 60 participants limits statistical power and generalizability of findings.
• Cross-sectional design prevents analysis of causal relationships or longitudinal changes in muscle properties.
• Data is presented in a DOCX document (25.8 KB), which is not a standard structured data format for direct analysis.
