Summary
Dominant hand grip and pinch strength are generally greater than the non-dominant hand. However, left-handed individuals showed a higher percentage of stronger non-dominant hands compared to right-handed individuals.
Area of Science:
- Hand strength assessment
- Upper extremity function
- Dominant vs. non-dominant hand performance
Background:
- Hand strength evaluation is crucial for assessing treatment effectiveness.
- Grip and pinch strength offer objective measures of upper extremity function.
Purpose of the Study:
- To compare grip and pinch strength between dominant and non-dominant hands.
- To investigate these differences in both right-handed and left-handed populations.
Main Methods:
- Involved 149 participants (128 right-handed, 21 left-handed).
- Grip strength measured using a Jamar dynamometer.
- Pinch strength measured using a manual pinchmeter.
Main Results:
- The dominant hand showed significantly greater grip and pinch strength overall.
- 10.93% of right-handed individuals had stronger non-dominant grip strength.
- 33.33% of left-handed individuals had stronger non-dominant grip strength.
Conclusions:
- Right-handed individuals exhibit significantly stronger dominant hands.
- No significant side difference in strength was found for left-handed individuals.
