Summary
This study determined normal key pinch strength values in a Nigerian population. Results indicate lower pinch strength compared to Caucasian populations, with variations by gender and age.
Area of Science:
- Orthopedics
- Hand Surgery
- Ergonomics
Background:
- Machine hand injuries necessitate establishing normal key pinch strength benchmarks.
- Restorative surgery outcomes require reliable reference values for hand function.
Purpose of the Study:
- To determine normal key pinch strength values in a Nigerian population.
- To analyze the influence of age, gender, BMI, hand dominance, and hand span on pinch strength.
Main Methods:
- Cross-sectional survey of 242 participants without prior hand injuries.
- Key pinch strength measured using the Baseline Hydraulic Pinch Gauge.
- Statistical analysis included independent sample t-tests and Pearson's correlation.
Main Results:
- Males exhibited higher pinch strength than females.
- Pinch strength peaked in the fifth decade for both genders.
- Hand span and height correlated with pinch strength in females.
Conclusions:
- Normal key pinch strength values in this Nigerian cohort are lower than those reported for Caucasian populations.
- Findings provide essential normative data for clinical and surgical applications in Nigeria.
