About this study
Official title: Preparation and Construction of Volumetric Plastination Models of the Limbic System, Basal Nuclei, Cerebellum, and Human Spinal Cord and Evaluation of Their Educational Effects
Purpose:
This educational trial aims to assess whether plastination models for neuroanatomy training (limbic system, basal ganglia, cerebellum, spinal cord)" improve medical students' understanding of central nervous system anatomy compared to traditional educational methods. It will also evaluate student satisfaction with this teaching tool.

Key Questions:
- Do plastination models for neuroanatomy training (limbic system, basal ganglia, cerebellum, spinal cord) enhance test scores in neuroanatomy examinations?
- How do students perceive the educational value of these models?
Study Design:
Researchers will compare two teaching methods:
- Intervention group: Learns using plastination models for neuroanatomy training (limbic system, basal ganglia, cerebellum, spinal cord)
- Control group: Learns using standard 2D atlases, power point and plastic models
Participants will:
- Complete a pre-intervention anatomy knowledge test
- Attend 4 weekly neuroanatomy sessions using their assigned method
- Take a post-intervention exam and satisfaction survey
- Participate in focus groups about their learning experience
- Being tested
- Plastination Model Group, Traditional Methods Group
- Keywords
- Medical education, Neuroanatomy, plastination model
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Plastination Model GroupBehavioural
Model Specifications:
"S10 silicone plastination models of brainstem structures (1:1 scale) with:
- Sectioned at 2mm intervals to reveal internal architecture
Traditional Methods GroupBehavioural
- Netter's Atlas of Human Anatomy (9th ed.)
- Standardized PowerPoint lectures
| Study group | Role | What they receive |
|---|---|---|
| Arm 1 : Plastination Model Group | Experimental | Receives instruction using plastinated models of:
* Brainstem
* Limbic system
* Basal ganglia
* Cerebellum
* Spinal cord
Duration: 7 weeks of training (2 hours/week)
Taught by professor who every year teaches neuroanatomy
Assessment: Standardized anatomy exams + spatial reasoning tests Receives: Behavioral: Plastination Model Group |
| Traditional Methods Group | Active comparator | Receives equivalent instruction using:
* Standard textbook and 2D atlases (e.g., Netter's)
* Lectures with 2D projections
Matched in duration and instructor expertise
Same assessment protocol as an experimental group Receives: Behavioral: Traditional Methods Group |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in neuroanatomy knowledge scores assessed by the "Neuroanatomy Knowledge Assessment Test
Scale Title: Neuroanatomy Knowledge Assessment Test (NKAT). Score Range: 0 (no correct answers) to 15 (all answers correct). Interpretation: Higher scores indicate better neuroanatomy knowledge (better outcome).
Measured: Baseline, Week 4 post-intervention
Secondary outcomes (2)
Spatial understanding assessment
Method: 3D spatial reasoning test (modified Vandenberg scale)
Scoring: 1-5 Likert scale for structure identification accuracy
Measured: Post-intervention only
Student satisfaction assessed by the 10-item Student Satisfaction Survey (SSS)
- Score Range: 1 (strongly disagree) to 5 (strongly agree).
- Interpretation: Higher scores indicate greater satisfaction (better outcome).
Measured: Immediately after the intervention (Day 1)

Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 28 May 2025. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?
Contact Mehrnoush Malekzadeh, Ph.D (09133097258, mehrnoush.malekzadeh@med.mui.ac.ir), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in neuroanatomy knowledge scores assessed by the "Neuroanatomy Knowledge Assessment Test (time frame: Baseline, Week 4 post-intervention). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 May 2025.
