Abstract

Aims:

The study aimed to assess the percentage difference of hand dimensions and their correlation with grip and pinch strength among school children in Saudi Arabia.

Materials and Methods:

Anthropometric measurements, hand dimensions, grip, and pinch strength measurements were obtained from 200 healthy schoolchildren in both genders aged 6-16 years. A Jamar electronic handgrip dynamometer was used to measure handgrip strength in kg. Pinch dynamometer was used to measure the two-point pinch strength, three-point pinch strength and lateral pinch strength in kg. Hand circumference was measured following hand arch at the maximum palm level. Hand span from the tip of the thumb to the tip of the little finger with the hand opened as broad as possible. Hand length from the tip of the middle finger to the midline of the distal wrist crease. Palm length from the distal wrist crease to the base of the middle finger.

Results:

The percentage of difference of hand dimensions between both the genders was statistically significant. Both handgrip and pinch strength were significantly correlated with anthropometric measurements and hand dimensions. Body mass index had mild correlation with both handgrip strength and pinch strength (P < 0.05). Age, hand circumference, hand span, hand length and palm length had moderate to strong correlation with both grip and pinch strength (P < 0.01).

Conclusion:

The current study provides a source of perspective reference values in clinical settings for hand dimensions. The present study showed significant correlations with handgrip and pinch grip strengths among schoolchildren in Saudi Arabia.
