Evaluation of lifting motion and voluntary training considered from the perspective of basic research: motion characteristics of lifting motions and methods of determining functional disorders

Abstract

In this paper, we explain the evaluation and treatment strategies of lifting motion with reference to our previous studies. Our previous studies have revealed that the pelvic position of the lifting motion is related to the postures of the knee and ankle joints. Based on the results of these previous studies, we consider that evaluation focusing on the ankle joint is useful for the evaluation of cases that complain of low back pain in a lifting motion. When the object is light, the activity of the tibialis anterior muscle tends to increase, and when the object is heavy, the activity of soleus muscle tends to increase.
