Uneven Landscape of Cognitive-Motor Dual-Task Research Across Rehabilitation Fields: A State-of-the-Field and Pattern
1Department of Physical Education, Seoul National University, Seoul, Republic of Korea.
Summary
Cognitive-motor dual-task (CMDT) research is concentrated in neurology and geriatrics due to historical factors and differing priorities. This imbalance limits CMDT
Area of Science:
- Rehabilitation Science
- Motor Control
- Clinical Research
Background:
- Cognitive-motor dual-task (CMDT) research has grown significantly but is concentrated in geriatric and neurologic rehabilitation.
- Other rehabilitation fields like musculoskeletal and sports medicine show limited engagement with CMDT despite its relevance.
Purpose of the Study:
- To synthesize the current state of CMDT research and examine structural mechanisms behind its uneven distribution across rehabilitation disciplines.
- To understand why CMDT has flourished in specific fields while remaining limited in others.
Main Methods:
- Literature synthesis and analysis of recurring patterns in CMDT research adoption.
- Examination of historical emergence, outcome prioritization, assessment standardization, clinician barriers, and expertise accumulation.
Main Results:
- CMDT research concentration is driven by historical emergence in gait/balance/cognitive decline domains.
- Unequal prioritization of CMDT-sensitive outcomes and lack of standardized assessments limit its adoption elsewhere.
- Clinician barriers and established expertise further reinforce the interdisciplinary imbalance.
Conclusions:
- The uneven distribution of CMDT research reflects deeper disciplinary structures within rehabilitation science, not a transient artifact.
- Understanding these mechanisms is crucial for a conceptual foundation of CMDT's varying applicability across fields.
