[Cervical lordosis evaluation in asymptomatic volunteers from Navy Medical Center].
OBJECTIVE
To evaluate the cervical lordosis in standing posture in healthy volunteers from the Navy Medical Center, by means of measurement of the angle of Cobb.


METHODS
The present is a descriptive, cross-sectional, with descriptive statistic and stratified sampling trial. The lateral radiographs of 81 healthy volunteers were analyzed. The technique used was obtained with the patients in standing posture, with eyes opened and to assume a comfortable neutral resting position, with 1 kg. in each upper extremity.


RESULTS
56 volunteers with medical activities, 90% displayed lost of lordosis. (Min 36 degrees, Max 76 degrees mean 54 degrees). Twenty five volunteers with office activities, 60% displayed lost of lordosis (Min 22 degrees, Max. 66 degrees, Mean 47 degrees). The ranks of interval for medical activities 50 to 65 degrees and for activities of office of 35 to 50 degrees (IC 95%).


CONCLUSIONS
Medical and office activities are associated with asymptomatic loss of cervical lordosis, with greater association of medical activities. Lateral radiographs in standing posture, allow suitable evaluation of the cervical spine without modifying its alignment.
