Background:
Depressive symptoms are common in individuals with inflammatory bowel disease (IBD) and are associated with poor disease outcomes. Transcutaneous electrical acupuncture point stimulation (TEAS) is a noninvasive intervention with potential benefits for inflammation but remains untested in IBD. We developed a smartphone application for home-based TEAS self-administration and evaluated its feasibility, acceptability, and preliminary effects.
Methods:
In a randomized feasibility study, IBD patients with Patient Health Questionnaire-9 (PHQ-9) scores ≥ 8 were recruited through Crohn's and Colitis UK. Participants were remotely trained to use the TEAS device, locate acupoints, and self-administer the treatment via the app. Group A completed 30-min daily sessions for 21 days from week 1, while Group B started in week 6. Outcomes [recruitment, retention, acceptability, depression, fatigue, pain, and quality of life (QoL)] were assessed at baseline, week 4, and week 9.
Results:
Of the 109 individuals of interest, 57 were assessed, 37 were eligible, and 36 were randomized. In Group A, 83% (15/18) completed ≥ 18 sessions, compared to 50% (9/18) in Group B. The questionnaire completion rates were 92% ( n = 33) at baseline, 83% ( n = 30) at 4 weeks, and 67% ( n = 24) at 9 weeks. Most participants (81%) recommended TEAS. Preliminary analysis showed reduced depressive symptoms and improved QoL postintervention and at the follow-up. Postintervention, the mean PHQ-9 score decreased from 13.9 to 7.7 in Group A and from 14.2 to 6.5 in Group B.
Conclusions:
Home-based TEAS is feasible, acceptable, and has a clinical potential. A full-scale randomized controlled trial is needed to confirm its efficacy in the treatment of IBD-related depression.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
