Mapping Rehabilitative Modalities in Major Depressive Disorder: A Cross-Sectional Bibliometric and Clinical Trial Analysis

Abstract

Gregory K Tharp

Background: The global burden of Major Depressive Disorder (MDD) has surged substantially, necessitating modalities that transcend traditional mono-therapies to incorporate comprehensive rehabilitation framework models.

Objective: To cross-sectionally map and evaluate the scope of neurorehabilitative and adjunctive therapeutic strategies for MDD documented within global doctoral dissertations and active clinical trial registries from 1950 to 2026.

Methods: A cross-sectional bibliometric analysis was conducted using the WorldCat database (N=3,914 initial records screened) and ClinicalTrials.gov. Search queries targeted dissertations and clinical protocols intersecting "Major Depressive Disorder" and "Rehabilitation." Identified interventions were categorized across mechanistic and clinical domains.

Results: The synthesized literature reveals five key rehabilitative domains:

1. Digital therapeutics and telerehabilitation;

2. Multidisciplinary manual and somatic therapies (e.g., Integrated Manual Therapy, Tuina);

3. Patient-driven self-care and botanical interventions;

4. Advanced neuromodulation and neurosteroid pharmacotherapies; and

5. Community-integrated psychoeducation and self-management models.

Conclusion: Managing MDD requires an integrated mind-body rehabilitation model addressing autonomic, cognitive, and psychosocial dimensions. Future research must evaluate protocol adherence, intervention efficacy, and drug-herbal interactions across diverse demographic cohorts.
