Summary
This study establishes normal handgrip strength values for Chilean adults aged 20-70. These reference ranges are crucial for identifying abnormalities and managing conditions like sarcopenia.
Area of Science:
- Clinical Physiology
- Public Health
- Gerontology
Background:
- Low hand grip strength is a significant prognostic indicator in both healthy individuals and hospitalized patients.
- Establishing local normative values for hand grip strength is essential for defining abnormality thresholds.
Purpose of the Study:
- To measure handgrip strength in a Chilean population aged 20 to 70 years.
- To propose normative values for healthy individuals within this demographic range.
Main Methods:
- Handgrip strength was assessed using a JAMAR hydraulic dynamometer.
- Data was collected from 436 males and 465 females aged 20-70, self-reported as disease-free.
- Participants were recruited from hospital and clinic waiting rooms.
Main Results:
- Handgrip strength values were tabulated by age and sex.
- Variability in handgrip strength was observed to be lower in women compared to men.
- Ranges encompassing three standard deviations were calculated for normative data.
Conclusions:
- The study provides essential normative handgrip strength data for the Chilean population.
- These values aid in the diagnosis and management of conditions such as sarcopenia, obesity, and Intensive Care Unit-acquired weakness.
- The findings support clinical decision-making for patients undergoing mechanical ventilation weaning.
