Summary
This study established hand grip strength (HGS) norms for healthy central Indians using a grip force transducer. Men showed higher HGS than women, and strength decreased with age.
Area of Science:
- Physiology
- Sports Medicine
- Rehabilitation Science
Background:
- Hand grip strength (HGS) is a key indicator of muscular function, physical status, and functional ability.
- It is crucial for identifying impairments and evaluating rehabilitation effectiveness in upper extremity injuries.
- Establishing normative data is essential for accurate clinical interpretation.
Purpose of the Study:
- To estimate HGS using a grip force transducer in a healthy central Indian population.
- To establish normative reference data for this demographic.
- To explore relationships between HGS and variables like age, BMI, heart rate (HR), and electromyography (EMG).
Main Methods:
- Descriptive, cross-sectional study involving 400 healthy volunteers (aged 17-65) from central India.
- HGS measured using a grip force transducer.
- Surface EMG and HR data collected; analysis performed using specialized software.
Main Results:
- Mean HGS was significantly lower in women than in men.
- A significant inverse correlation was found between HGS and age in both sexes.
- HR showed a weak positive correlation with HGS; EMG showed a non-significant weak positive correlation.
Conclusions:
- Age-specific normative HGS values were established for the central Indian population.
- Significant sex-based differences in HGS were observed, with men having greater strength.
- HGS is inversely related to age and positively correlated with HR, though correlations are weak.
