Normative values for hand grip strength in Trinidad And Tobago

ABSTRACT

Objectives: To establish normative Hand Grip Strength (HGS) data for Trinidad and Tobago and to assess factors that may influence hand grip strength within this population. Design and Methodology: A cross sectional study of participants between the ages of 18-80 years was conducted at five distinct geographic regions in Trinidad and Tobago. Demographic data was collected including hand dominance. HGS was measured using a Jamar dynamometer. Descriptive statistics were performed for all direct measurements and Pearson's correlation coefficient used to analyze the relationship between variables. All statistical analysis was performed using the Statistical Package for Social Sciences (SPSS v20) p-value < 0.05 was considered significant. Results: A total of 1354 participants took part in the study, with 121 exclusions leaving 1233 for analysis. There were 561 males (45.5%) and 672 females (54.5%). The mean age of the participants was 42.5 years (SD +/-15.5) and mean body mass index (kg/m2) 27.3 (SD +/- 6.0). The overall mean HGS for our sample was 28.4 kgs. (SD +/- 2.9) with males having a higher overall HGS compared with females. Conclusions: This study presents previously unreported normative data on HGS in a Trinidad and Tobago population. This data will allow for a more objective evaluation of hand function in patients following injury and has implications for the assessment of disability in workmen's compensation.
