Measurement of hand grip strength by digital jamar hand dynamometer: a study on CRP staffs & BHPI students

Abstract

Background: Hand grip strength is a useful measurement for individuals. The aim of the study was to describe normative data for hand grip strength in Bangladeshi adult population. The objectives were to explore association between dominant HGS with age, gender, height, weight, Occupation, BMI, Hand length, Hand breadth and compare between dominant HGS with the group of high manual occupational strain and low manual occupational strain. Methodology: This study was done by quantitative method. The nature of the study is cross sectional study. The participants were selected purposively. The study participant areas within age range of 18 to 40 years. For HGS analysis, the 384 participants were divided into four categories. based on age: (a) 18–23years; male ,(n=84) ; female, (n=154); (b) 24–29 years ; male ,(n=45); female, (n=34); (c) 30–35 years; male ,(n=13); female, (n=11); and (d) 36-40 years; male ,(n=25); female, (n=18).The data was collected by using Jamar hand dynamometer, consent form, tape measurement, information sheet. Result: In the present study there were 384 participants were selected. Where the male participants were 167and female participants were 217. Result from our study indicated a positive strong association of anthropometric measurement. Such as- hand length, hand breadth, height, weight, BMI. This study show correlation is significant when the P value is 0.01.The study sample was divided into two groups, as follows: 1.High manual occupational strain that was composed of 305 participants, 2. Low manual occupational strain that was composed of 79 participants. In our study the result was identified significant difference exist in dominant grip strength between the high manual occupational strain and low manual occupation group. Based on our study result it is confirmed that grip strength is higher in the high manual occupational group than low manual occupational strain group. Conclusion: This study explored the great importance for identifying impairments, establishing realistic goals, and determining the efficacy of interventions for patients with hand or upper extremity injuries or disabilities. HGS is used widely in clinical practice and research to assess the impact of a variety of disorders on hand function. Key words: Hand Grip Strength, Jamar Hand dynamometer, Normative data.
