Purpose: Three-dimensional (3D)–printed models have been increasingly used in medical education, but most studies have focused on satisfaction or outcomes following isolated learning activities. This study aimed to explore students’ perceptions of learning, engagement, usability, and learning strategies after completing a series of neuroanatomy-related coloring activities using a low-cost 3D-printed model. Methods: This cross-sectional study involved Year 1 medical students at Duke-NUS Medical School. Students participated in 3 structured coloring activities using a modular 3D-printed brain model during a neuroanatomy session. An anonymous survey was administered 1 week after the third activity to assess students’ perceived learning value, engagement (behavioral, cognitive, emotional, and agentic), usability, and learning strategies using Likert-scale items and open-ended questions. Results: A total of 48 students completed the survey, and the instrument showed acceptable to high internal consistency. Students reported high perceived learning value, positive engagement across multiple domains during the coloring activity, and high usability of the model. Participation in the learning activities was associated with significantly higher behavioral and agentic engagement, perceived learning value, and greater use of learning strategies than non-participation. Overall, active manipulation and hands-on exploration were perceived as beneficial for learning. Conclusion Low-cost 3D-printed brain models may serve as valuable learning tools to complement existing anatomy teaching approaches when paired with well-designed learning activities. Students reported positive learning experiences and high engagement during the activities. These findings highlight the importance of sound pedagogical design and curriculum integration to maximize learning.

INTRODUCTIONIntrathecal baclofen (ITB) therapy is a proven, effective treatment for disabling cortical spasticity. We describe the first local series of five patients with acquired brain injury (ABI) who received ITB and were followed up for 63.8 months.

METHODSA retrospective review of medical and rehabilitation records of patients who received ITB therapy was carried out. Data studied included baseline demographic and injury variables, implantation data, spasticity and function, ITB dosage over time and complications.

RESULTSFrom 2006 to 2010, a total of five patients received ITB therapy via implanted pumps about 39.4 months after ABI. Four out of five patients experienced significant reductions in their lower limb spasticity scores and improvements in global function and dependency. One patient had minor adverse events associated with baclofen-related sedation. The mean ITB dose at one year was 182.7 ± 65.6 mcg/day.

CONCLUSIONOur preliminary study showed encouraging long-term outcomes and safety for ITB therapy after ABI-related intractable spasticity. Individual ITB responses over time were variable, with gender differences. The outcomes experienced by our centre were comparable to those in the general ABI population, supporting the efficacy of ITB therapy for chronic disabling spasticity.
