OBJECTIVES: The aim of this study was to sonographically measure and compare the pronator quadratus muscle thickness (PQMT) in apparently healthy volunteers between two occupational groups and to assess the influence of hand dominance on the PQMT. METHODS: A total of 180 apparently healthy volunteers were enrolled in the study. The volunteers were grouped into repetitive (90) and nonrepetitive (90) workgroups. They were scanned with a B-mode ultrasound machine and linear transducer. RESULTS: The mean PQMT was significantly higher (P < 0.05) in the repetitive workgroup than in nonrepetitive workgroups. Similarly, a significant difference in mean PQMT was observed between dominant and nondominant hands in the repetitive workgroups (P < 0.05). CONCLUSION: The mean PQMT among repetitive workgroup is significantly higher when compared with nonrepetitive workgroups in the study area.
