INTRODUCTION: Electrogoniometers have been used to record wrist movements during work. However, different sizes of sensors are used making the comparison of recordings difficult. OBJECTIVE: To evaluate two different sensors in order to check its performance in an anthropometric defined sample. MATERIAL AND METHODS: Thirteen subjects (7 women and 6 men; age 23 ± 2.6 years; weight 57 ± 3.8 kg and height 1.63 ± 4.1 m) participated in this study. Two sensors with 65 and 110 mm of length (XM110 and XM65, respectively) and an acquisition data device (Datalog, Biometrics) were used to collect data. Anthropometric measurements of participants were recorded. Each subject performed flexion/extension and ulnar/radial wrist movement, reaching maximum amplitude in the pronated forearm position. The movement order and sensor placement were randomized. The data were analyzed descriptively and statistically (multivariate analysis). The intra-individual variation (root mean square - RMS - between trials) were calculated. RESULTS: There was no significant difference between the sensors for all movements. The maximum intra individual variation was 2.2º. There were significant differences between genders for wrist flexion and ulnar deviation, women have higher values than men. The maximum variability between sensors was 7.1º. CONCLUSION: Although no significant difference was identified between sensors, it was found that the sensor XM110 suffered bulging during the extension. Therefore, for individuals with height up to 1.8 m, the data obtained by different sensors are comparable
