Hand Gripping Assessment in Female Nail Artist: A Cross-Sectional Study

Background: Nail artists are exposed to various ergonomic stressors due to repetitive hand movements, which may affect their hand grip strength and pinch strength. This study aims to assess these parameters in female nail artists to understand the potential occupational impacts on hand function. Materials and Methods: A cross-sectional study was conducted involving 100 female nail artists aged 18-35 years, working in various nail salons in Surat. The Jamar hand dynamometer and Jamar pinch meter were used to measure hand grip strength and pinch strength in both dominant and non-dominant hands. Data were collected from September 2023 to March 2024 using convenient sampling. Results: The study participants had a mean age distribution with 23% in the 18-23 age group, 63% in the 24-29 age group, and 14% in the 30-35 age group. Statistical analysis using SPSS software revealed significant differences in cylindrical grip strength between the dominant and non-dominant hands. There was also a notable relationship in pulp-to-pulp pinch strength. Conclusion: The study found no significant difference in hand grip strength and pinch strength in female nail artists compared to normal individuals. However, the findings suggest that prolonged exposure to repetitive hand movements may lead to overuse injuries and muscle weakness, affecting their ability to perform certain tasks.
