5. Conclusions
weight loss, SMI reduction
ADVERSE EVENTS, HEAD AND NECK CANCER, RECRUITMENT
Muscle-strengthening exercises were performed in patients undergoing CRT for head and neck cancer, and their effects before and after treatment were investigated using HD-sEMG. Although no significant changes were observed before and after treatment, significant correlations were observed between the rate of weight loss and SMI reduction and the rate of change in the recruitment of MU of the SHMG. Therefore, we believe that nutritional supplementation is necessary in addition to muscle strengthening during CRT. A detailed investigation of the changes over time may help us understand the effects of muscle strengthening and adverse events in detail.
