Two subjects were studied for 1 to 3 weeks during the course of their normal domestic activities. Utilisation profiles were derived for ten joints, using a systematic time-series sampling technique adapted from behavioural biology. At each joint the proportion of the available range utilised was noted. The results were compared with the known regional prevalence of primary osteoarthritis. There was a correlation between the degree to which a joint was incompletely utilised, and its susceptibility to osteoarthritis. The hypothesis is advanced that primary osteoarthritis may be due to incomplete joint utilisation.
在两名受试者正常的家庭活动期间，对他们进行了1至3周的研究。采用从行为生物学改编而来的系统时间序列抽样技术，得出了十个关节的使用情况概况。记录了每个关节在可用活动范围内的使用比例。将结果与已知的原发性骨关节炎区域患病率进行了比较。关节未充分利用的程度与其患骨关节炎的易感性之间存在相关性。由此提出一个假说，即原发性骨关节炎可能是由于关节使用不充分所致。
