Normative Values for Grip and Pinch Strength for 6- to 19-Year-Olds

Area of Science:

• Pediatric rehabilitation
• Human motor development
• Biometrics

Background:

• Accurate normative data for grip and pinch strength are essential for assessing pediatric and young adult hand function.
• Previous normative values may no longer reflect current population capabilities.

Purpose of the Study:

• To establish current grip and pinch strength norms for individuals aged 6 to 19 years.
• To investigate the influence of age, sex, and hand dominance on these strength measures.

Main Methods:

• A descriptive, cross-sectional study involving 1508 male and female students aged 6 to 19 years.
• Grip, tip pinch, lateral pinch, and palmar pinch strengths were measured.
• Data were analyzed using analysis of covariance and 2-sample t tests, stratified by age and sex.

Main Results:

• Both age and sex significantly influenced hand strength, with strength increasing with age and being greater in males.
• Hand dominance did not show a significant effect on hand strength.
• Current normative values were significantly lower than those published 28 years ago.

Conclusions:

• Updated normative data for grip and pinch strength are crucial for rehabilitation practitioners.
• These updated norms allow for more accurate assessment of impairment and progress tracking in young individuals.
• The study highlights the necessity of regularly updating normative strength data due to observed changes over time.
