NCT07720336

Brief Summary

This study will investigate how two inhaled essential oil products (QueaseEASE and STILL) and a wearable transcutaneous electrical nerve stimulation (TENS) device (ReliefBand) affect chronic nausea and anxiety in adults with longstanding nausea. The goal is to better understand the mechanisms by which these non-prescription therapies may influence nausea, anxiety, sleep, pain, autonomic symptoms, and bowel-related symptoms. Participants will first complete a 2-week baseline period during which nausea and other symptoms are assessed through questionnaires. Participants will then use the inhaled essential oil products as needed for 12 weeks while completing symptom surveys. Afterward, participants will use the ReliefBand wearable TENS device as needed for an additional 12 weeks and continue completing surveys. Researchers will compare symptom changes during the intervention periods with baseline measurements to better understand factors that contribute to chronic nausea and how these therapies may provide relief. Up to 250 participants may be enrolled to achieve approximately 100 participants completing both intervention phases

Outcome Measures

Primary Outcomes (2)

  • Change in Anxiety Severity as a Potential Mechanism of Chronic Nausea

    Change in anxiety severity from baseline during inhaled essential oil use assessed using the Generalized Anxiety Disorder-7 (GAD-7) questionnaire. Modulation of anxiety severity is hypothesized as a mechanism by which Inhaled essential oils affect chronic Nausea

    Baseline through 3 months

  • Change in Anxiety Severity as a Potential Mechanism of How TENS Units Affect Chronic Nausea

    Change in anxiety severity from baseline during wearable TENS device use, assessed using the Generalized Anxiety Disorder-7 (GAD-7) questionnaire. Modulation of anxiety severity is hypothesized as a mechanism by which TENS units affect chronic Nausea

    Change from 2nd baseline to 3 months after using TENS unit

Secondary Outcomes (2)

  • Change in Autonomic Symptom Burden as a Potential Mechanism by which Inhaled Essential Oils Affect Chronic Nausea

    Baseline to 3 months

  • Change in Autonomic Symptom Burden as a Potential Mechanism by which TENS units Affect Chronic Nausea

    Second Baseline to 3 months after using TENS unit

Study Arms (1)

Sequential Essential Oil and TENS Intervention

EXPERIMENTAL

All participants complete a 2-week baseline assessment period followed by 12 weeks of use of inhaled essential oil products (QueaseEASE for nausea and STILL for stress or anxiety) as needed. Participants then complete 12 weeks of use of a wearable transcutaneous electrical nerve stimulation (TENS) device (ReliefBand) as needed for nausea. The study is designed to evaluate changes in factors that may contribute to chronic nausea, including anxiety, stress, sleep disturbance, pain, autonomic symptoms, and bowel-related symptoms. Participants serve as their own controls through comparison with baseline assessments.

Other: Inhaled Essential OilsDevice: Wearable TENS Device

Interventions

participants will use the ReliefBand wearable transcutaneous electrical nerve stimulation (TENS) device during a 12-week intervention period following completion of the inhaled essential oil phase. The device is worn on the wrist and delivers electrical stimulation to the median nerve. Participants will use the device as needed for nausea and will not use the inhaled essential oil products during this phase. The intervention is being studied to evaluate potential mechanisms through which wearable TENS therapy may influence nausea and related symptom domains, including anxiety, stress, sleep disturbance, pain, autonomic symptoms, and bowel-related symptoms.

Sequential Essential Oil and TENS Intervention

Participants will use two commercially available inhaled essential oil products during a 12-week intervention period. QueaseEASE, containing peppermint, ginger, lavender, and spearmint essential oils, will be used as needed for nausea. STILL, containing sweet orange, ylang ylang, lavender, and bergamot essential oils, will be used as needed for stress or anxiety. Participants may use either or both products according to their symptoms. The intervention is being studied to evaluate potential mechanisms through which inhaled essential oils may influence nausea and related symptom domains, including anxiety, stress, sleep disturbance, pain, autonomic symptoms, and bowel-related symptoms.
