Table 3_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 lower-limb isometric strength across eight movements and tensiomyography-derived contractile properties for four muscles. The data was collected by Sunghoon Shin and published in 2026.

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 for individuals with Parkinson's disease.
• Investigate neuromuscular impairment patterns by comparing Tc and Dm values across the four measured muscles (lateral gastrocnemius, medial gastrocnemius, soleus, tibialis anterior).
• Examine the association between maximal voluntary contraction values and participant classifications (Parkinson's disease status, sarcopenia status).

Strengths

• Includes data from 60 participants with a defined age range of 58-85 years.
• Provides measurements for eight lower-limb isometric strength tasks and contractile properties for four specific muscles.
• 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.
• Cross-sectional design prevents analysis of causal relationships or disease progression.
• Data is presented in a DOCX file format (26.3 KB), which is not a standard structured data format for analysis.
