Abstract
Background: A normal Finger Flexion Cascade (FFC) is formed by the fingers of the hand when the hand in a relaxed position. Usually, the fingers of the hand assume a flexed position; gender may influence the normative values of the resting hand due to differences in the anatomical structure of hand and frequency of usage of joints of hand in their respective occupation and habitual activities of daily living. Hence the study aims to find the difference in the FFC between men and women in power grip and nonpower grip occupational activities.
Methods: A cross-sectional study was conducted in a mixed population of five hundred active individuals aged between 25 and 40 years belonging to various occupations of industrial work and individuals working with software companies. Individuals who fulfilled the inclusion criteria participated in the study. After completing a questionnaire based on occupation, the subjects were grouped into power grip users and nonpower grip users. The range of motion of the joints of all the fingers, namely, metacarpophalangeal, proximal interphalangeal, and distal interphalangeal joints of both dominant hand and nondominant hand was measured using universal finger goniometer, and the composite finger flexion was recorded using a geometric ruler. The results were analyzed, and Un-paired T-test was used to compare the FFC between the power grip and the nonpower grip group.
Results: The FFC variations in both the hands of male and female subjects in power grip users (PGU) and nonpower grip users(NPGU) were recorded. In the dominant hand, it was found that the DIP joint of 5th digit in female subjects had a greater ROM values than male subjects, but greater ROM values in MCP joints of the hand in males were found. The comparison between the range of values of both groups revealed that the values in the PGU group were more than the NPGU group with a statistical significance of p<0.001.
Conclusion: The finger flexion cascade was found to be more closed in female subjects than males in both the dominant and nondominant hands of in the power grip users than in the nonpower grip users.
