摘要
the present work on the rotation between the cervical spine and the head in humans aims to standardize the grades of cervical and capital rotation, both to the right and to the left, in a random sample obtained from individuals of both genders in the caldas state (colombia), stratified according to their life cycle from three years of age and exhibiting no alteration in the movements peculiar to the region mentioned above.through statistical tables the experimental results are shown and these are compared with values reported in the literature.also, we observed that the values obtained are within the range established in the literature, however, the data referred herein are much more specific because they involve comparisons between the age and gender ranges, data not covered in the texts consulted. we conclude that although the range of rotation for the population of caldas is within the range reported (60 to 80 degrees), it is very close to the lower limit (60.99 degrees).also shown is the finding of a statistically significant change in the analysis of cervical and capital rotation values in the age range between 19 to 25 years in both genders.
