The reconstruction of activity and of work patterns has been approached by examinations of activityrelated skeletal markers. Among several different methods, in particular, a number of anthropologists have widely applied the patterns of enthesopathies and degenerative joint disease in studies of past activity. The purpose of this study is to better understand and use these indicators in reconstructing the levels of physical activities of past populations.
This review will provide information on the most recent anthropological research on the behavioral interpretation on degenerative joint disease and enthesopathies, to better use these indicators in understanding past populations.
There are obvious limitations in using these markers, and it is necessary to consider them. Firstly, it is uncertain as to whether there are certain activities that are performed repetitively throughout their lives of those who lived in past civilizations. A second limitation involves the etiology of skeletal markers related to mechanical stress. There are multiple-factors, including genetic predisposition, sex, the aging process, and diet that may affect the way people practice a specific activity. Accordingly, this makes it difficult to evaluate the underlying etiological factors and their roles in activity-related skeletal changes.
In conclusion, to circumvent these limitations, the use of multiple skeletal markers together in studies of the activities of past populations may enable to more reliable interpretations. However, to ensure more reliable interpretations, the validity of such combinations of makers should be challenged. Therefore, more work on the validity of activity-related markers is needed to clarify the activities that are responsible for the development in life of the features observable in skeletal populations. This type of research can contribute to the discussion of the use of activity-related skeletal markers in studies of behavioral interpretations with more certainty regarding which morphological characteristics are responses to physical activity and mechanical loading as the pathogenesis of such characteristics.
