Table 6_Cross-sectional comparison of lower-limb muscle strength and contractile properties according to Parkinson’s disease and sarcopenia status.docx

Aggregating cross-sectional measurements from 60 older adults (20 with Parkinson's disease, 40 age-matched controls) assessing lower-limb isometric strength across eight movements and tensiomyography-derived contractile properties for four muscles. It compares muscle function between Parkinson's disease and sarcopenia statuses, with predefined covariate control. The data includes metrics such as contraction time (Tc) and maximal muscle displacement (Dm).

Use Cases

• Compare contraction time (Tc) and maximal muscle displacement (Dm) values between Parkinson's disease patients and healthy controls for the lateral gastrocnemius muscle.
• Analyze peak isometric strength in hip and knee extension tasks across sarcopenia classifications to identify task-specific deficits.
• Investigate correlations between tensiomyography-derived contractile properties of the soleus and tibialis anterior muscles and Parkinson's disease motor symptoms.
• Model the relationship between maximal voluntary contraction measurements for eight lower-limb movements and participant age or disease status.

Strengths

• Includes data from 60 participants, with 20 diagnosed with Parkinson's disease and 40 age-matched healthy 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) for the lateral gastrocnemius in 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 disease status and muscle properties.
• Data is contained in a 25.6 KB DOCX file, indicating a small, likely summary-level dataset rather than raw individual-level records.
