NCT05785117

Brief Summary

Participants were randomly assigned to two groups prior to their second visit: the Vagus nerve stimulation group (VNS) and the circuit training program. The randomization processes were conducted in Excel utilizing a random-number generator. Prior to the second visit, each participants' target exercise heart rate ranges were determined. Vagus nerve stimulation group(VNS) Patients rested on their sides in a sitting position. Following regular disinfection of the stimulation locations, ear clips were placed in the ear region (auricular concha) at the stimulation site. The training regimen included ten different forms of resistance and aerobic exercises.

Outcome Measures

Primary Outcomes (3)

  • Emotional eating

    Emotional Eating was measured by a 15-item version of the Emotional Eating Scale. The scale required responses from 0 (no desire to eat) to 4 (an overwhelming urge to eat) based on "… the extent which the following feelings presently lead you to feel an urge to eat. A lower score indicated less of an urge to eat when the designated emotional state was present.

    4 weeks

  • Patient satisfaction measures

    The Short Assessment of Patient Satisfaction (SAPS) is a seven-item scale that can be utilized to measure patient satisfaction with their treatment. The seven-item Short Assessment of Patient Satisfaction (SAPS), which is scored on a 5-point scale (0-4) SAPS has a continuous score range of 0 to 28. SAPS categorical responses include 0-10 very dissatisfied, 11-18 dissatisfied, 19-26 satisfied, and 27-28 very satisfied.

    4 weeks

  • Cortisol level

    Participants use a disposable plastic straw to 'drool' saliva into the tube after collecting it in their mouths for a predetermined period of time (one minute) Saliva samples for cortisol measurement kept at room temperature until they are examined in a lab (4 to 6 hours)

Other: Circuit training program

Interventions

ear clips were placed in the ear region (auricular concha) at the stimulation site. The following stimulation settings were used: 1) density wave set to 20 Hz with a wave width of less than 1 ms; 2) intensity tuned to the patient's tolerance (4-6 mA)

Vagus nerve stimulation group

The training regimen included ten different forms of resistance and aerobic exercise that were done three times a week for four weeks. The resistance training program included push-ups, squats, crunches, lunges, and a superman exercise program that included light jumping, jogging on the spot, foot stomping, steps, and jumping jacks
