Table 2_Cross-sectional comparison of lower-limb muscle strength and contractile properties according to Parkinson’s disease and sarcopenia status.docx

Featuring cross-sectional measurements from 60 older adults (20 with Parkinson's disease, 40 age-matched controls) aged 58–85 years. It compares lower-limb isometric strength across eight movements and tensiomyography-derived contractile properties for four muscles.

Use Cases

• Analyze differences in contraction time (Tc) and maximal displacement (Dm) for the lateral gastrocnemius muscle between Parkinson's disease and control groups.
• Compare peak isometric strength in hip and knee extension tasks between sarcopenic and non-sarcopenic participants.
• Investigate correlations between muscle contractile properties (e.g., Tc, Dm) and isometric strength measurements across the eight lower-limb movements.
• Examine the distribution of neuromuscular measurements across the cohort segmented by Parkinson's disease status, sarcopenia classification, and gender (39 males, 21 females).

Strengths

• Includes data from 60 participants, with a defined cohort of 20 Parkinson's disease patients and 40 age-matched healthy controls.
• Provides measurements for eight specific lower-limb isometric strength tasks and contractile properties for four distinct muscles (lateral gastrocnemius, medial gastrocnemius, soleus, tibialis anterior).
• Reports 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 analysis of causal relationships or progression of muscle properties over time.
• Data is presented in a DOCX document (26.0 KB), indicating it is likely a summary table or manuscript, not a raw, machine-readable tabular dataset.
