The concept of constraint-induced language therapy originated in which field?

• A. Psychology
• B. Physical Therapy
• C. Occupational Therapy
• D. Speech-Language Pathology

Answer: (B)

The idea behind constraint-induced language therapy comes from the rehabilitation approach used to improve motor function after brain injury, specifically Constraint-Induced Movement Therapy. The key tactic is to force use of the affected area by constraining the unaffected one and providing intensive, task-focused practice. This principle was developed in the field of physical therapy and neurorehabilitation, where researchers showed that repetitive use of the impaired limb could overcome learned nonuse. Speech-language pathologists later adapted the same concept to language tasks, naming it constraint-induced language therapy, but its origins are in physical therapy.
