The purpose of the present study was to compare and analyze the concordance of three instruments (Inclinometer Lafayette, fleximeter Sanny, and fleximeter Code) in flexion and extension of cervical spine. The sample was composed by forty-one college men (20.8 ± 2.2 years, 1.78 ± 0.07 m, 57.1 ±11.3 kg). For statistical analyses ANOVA one-way, Bland and Atlman procedures, multiple regression analysis, and Spearman correlation coefficient were employed, with P< 0.05. According to the results, there were no significant differences among scores produced by the three instruments for flexion (median=63 degrees; P=0.95) and extension of cervical spine (median=73degrees; P=0.90), and concordance scores, between the analyzes, near zero (-0.34< < 0.26). The results of this study indicate that the fleximeter Code, fleximeter Sanny, and inclinometer Lafayette measurement values are consistent, which allows comparisons between themselves and using similar cutoffs, specifically for healthy male college students, in flexion and extension of cervical spine, specifically for college men.
