Investigation of the Relationship of Wrist Range of Motion with 2D:4D Ratio in Healthy Individuals

Research Article




Range of Motion, 2D:4D Digit Ratio, Goniometer, Digital Caliper


Introduction: Range of motion (ROM) is widely used in the diagnosis of musculoskeletal disorders and in the evaluation of treatment prognosis. The 2D:4D ratio is the ratio of the second finger to the fourth finger.

Objective: The aim of our study is to investigate whether there is a possible relationship between ROM and finger length.

Method: In our study, 120 asymptomatic individuals (37.50% female) with a mean age of 33.73±14.12 years and a mean body mass index of 24.66±4.60 kg/m2 were included. After voluntary consent was obtained, ROM was measured using a goniometer and 2D:4D ratio was measured using a digital caliper. The IBM SPSS Statistics for Windows software (version 22.0; IBM, Armonk, NY) was used to analyze the data.

Results: In this study there was no any significant correlation between 2D:4D digit ratio for right hand and the other variables (p=0.127-0.902). There was a significant correlation between 2D:4D digit ratio for left hand and the weight (r=-0.288;p=0.001), and the body mass index (r=-0.282; p=0.002,). The stepwise multiple regression analysis demonstrated that the weight was significant and independent factor of the 2D:4D digit ratio for the left hand with 4.9% of the variance.

Conclusion: The lack of a study examining the relationship between ROM and 2D:4D ratio in the existing literature reveals the importance of the study data. Our suggestion is that the relationship with the 2D:4D ratio can be examined by measuring ROM measurements in patients and healthy individuals.
