Foot Reflexology and Ta-VNS for Symptom Management in Head and Neck Cancer During CCRT

July 23, 2026 updated by: Chun Hou Huang, Tzu Chi University

Efficacy of Foot Reflexology and Transcutaneous Auricular Vagus Nerve Stimulation on Pain, Xerostomia, Fatigue, Sleep, and Treatment-Related Symptoms in Head and Neck Cancer Patients Receiving Concurrent Chemoradiotherapy: A Randomized, Single-Blind, Sham-Controlled Trial

Head and neck cancer (HNC) patients undergoing concurrent chemoradiotherapy (CCRT) frequently experience pain, xerostomia, fatigue, sleep disturbance, and other treatment-related toxicities that impair quality of life and treatment adherence, with incomplete relief from current supportive care. This randomized, single-blind, sham-controlled trial evaluates whether foot reflexology (FR), transcutaneous auricular vagus nerve stimulation (ta-VNS), and auricular acupressure (AA) reduce pain, xerostomia, fatigue, sleep disturbance, and treatment-related symptoms in HNC patients receiving cisplatin-based CCRT, compared with usual care. Participants are randomized to a foot reflexology group, an auricular vagus nerve stimulation group (each with true and sham subgroups), or a usual-care control group, and are followed at baseline and weeks 1, 2, and 4.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a three-arm parallel, repeated-measures randomized controlled trial conducted in the otolaryngology outpatient and inpatient settings of Hualien Tzu Chi Hospital. Eligible patients with pathologically confirmed HNC (clinical stage II-IVA) scheduled to receive a second cycle of cisplatin-based CCRT are stratified by CRT dose (<66 Gy vs ≥66 Gy) and randomized using a computer-generated sequence with block size 4 or 8, in a 1:1:1 ratio, to the FR group, the ta-VNS group, or the usual-care control group; the FR and ta-VNS groups are further randomized to true or sham subgroups. The foot reflexology intervention is delivered twice weekly for 20 minutes over two weeks and comprises a relaxation phase, a head-neck/gastrointestinal regulation phase, and a circulation/detoxification phase; the sham condition applies light, non-specific touch. The ta-VNS intervention stimulates the left tragus, cymba conchae, and cavum conchae (pulse width 250 µs, 25 Hz, 0.5-5 mA individualized to a tingling sensation, 30 s on/off) twice weekly for 20 minutes over two weeks; the sham condition stimulates the left earlobe at 0.5 mA. Auricular acupressure with magnetic beads is self-administered three times daily. Outcomes are assessed at T0 (baseline), T1 (week 1), T2 (week 2), and T3 (week 4). Data are analyzed with generalized estimating equation (GEE) models.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
