[Effects of an Acupoint Intervention on Improving Fatigue and Heart Rate Variability in Head and Neck Cancer Patients Receiving Concurrent Chemoradiotherapy]

Background: Fatigue is the most common symptom in head and neck cancer patients who receive concurrent chemoradiotherapy (CCRT). However, evidence of the effects of acupoint interventions on fatigue and heart rate variability in these patients is unclear.

Purpose: To evaluate the effect of an acupoint intervention on fatigue and heart rate variability in head and neck cancer patients receiving CCRT.

Methods: This randomized controlled trail applied repeated measures, and used permuted block randomization to randomly assign the participants into the acupoint and control groups. Participants in both groups received usual care. In addition, participants in the acupoint group received transcutaneous electrical acupoint stimulation and auricular acupressure for a period of six weeks. Data were collected using the brief fatigue inventory and a heart rate variability device at baseline and during the 1st, 2nd, 3rd, and 6th weeks of the study.

Results: The generalized estimating equation analysis found a significant group-by-time interaction for fatigue on the 6th week of acupoint stimulation (p = .036). No significant differences in group-by-time interaction were found for the standard deviation of normal to normal intervals (SDNN), low frequency (LF), high frequency (HF), or LF/HF ratio (p > .05).

Conclusions / implications for practice: This study supports the accessibility and feasibility of the acupoint intervention. No adverse effects were observed. The six-week transcutaneous electrical acupoint stimulation and auricular acupressure may be used to improve fatigue in head and neck cancer patients currently receiving CCRT.
