7.1 Animal Placement * Gently pick up a rodent and place it at the bottom of the pole, facing
upwards.

7.2 Climbing Observation * Observe the animal's attempts to climb the pole for a
predetermined time period or until it reaches a designated point on the pole. * Note the animal's
climbing ability, grip strength, and any coordination issues.

7.3. Scoring (Optional) * Depending on your experimental design, a scoring system may be
established to quantify climbing success (e.g., reaching a specific height, time spent climbing)
based on IACUC guidelines.

8. Post-Testing

8.1 Animal Recovery * Return the animal to its home cage after testing. * Monitor the animal
for any signs of distress and provide veterinary care if necessary.

8.2 Apparatus Cleaning * Clean the pole climbing apparatus with disinfectant after each testing
session.

9. Maintenance

● Regularly inspect the pole climbing apparatus for damage or wear and tear.
● Tighten any loose screws or components as needed.
● Report any malfunctions or need for repairs to the designated personnel.

10. Reference Documents

● IACUC protocol approval for your specific pole climbing experiment.

11. Additional Notes

● This SOP is a general guideline and specific details may vary depending on the pole climbing
apparatus design, animal species, and your research objectives.
● Consider using a textured or grooved pole surface to improve the animal's grip.
● Avoid using excessively tall poles or testing durations that could lead to exhaustion or injury.

12. Ethical Considerations

● Use the pole climbing apparatus only for approved research purposes.
● Minimize stress and discomfort to the animals during testing.
● Monitor animal behavior and stop the test if signs of distress are observed.
● Provide adequate rest periods between trials if necessary.
Standard Operating Procedure (SOP) for Rotarod Testing

1. Purpose

This SOP outlines the procedures for the safe, consistent, and ethical use of a rotarod
apparatus to assess motor coordination and balance in rodents (mice or rats).

2. Scope

This SOP applies to all personnel conducting rotarod experiments on rodents within your facility,
such as animal research labs.

3. Responsibilities

● Animal Caretaker: Ensures animal health and well-being before, during, and after testing.
● Researcher/Technician:
○ Conducts rotarod testing following this SOP.
○ Maintains the rotarod apparatus in good working condition.

4. Animal Care and Use

● Ensure all procedures comply with your institution's Animal Care and Use Committee
(IACUC) protocols.
● Use only healthy rodents that have been acclimated to the testing environment.
● Minimize stress and ensure proper handling techniques throughout the experiment.

5. Apparatus Preparation

5.1 Cleaning and Disinfection * Clean the rotarod arena and lanes with disinfectant
appropriate for your facility. * Allow the arena to dry completely before use.

5.2 Rotarod Settings * Ensure the rotarod apparatus is level and functioning properly. * Set the
desired initial speed, acceleration rate (if applicable), and maximum speed based on your
experiment. * Choose appropriate lane separators based on the size of the rodents being
tested.

6. Animal Preparation

6.1 Acclimatization * Allow the animals to acclimatize to the testing room for at least 30
minutes before testing.

6.2 Habituation (Optional) * Consider including a habituation session where animals are
placed on the stationary rotarod for a short period to get familiar with the environment (following
IACUC guidelines).

7. Testing Procedure

7.1 Animal Placement * Gently pick up a rodent and place it on the rotarod lane, facing
forward.

7.2 Testing * Start the rotarod according to the chosen settings. * Record the latency (time) to
fall for each animal. * A cut-off time limit may be set to avoid excessive stress on the animal.

7.3 Data Collection * Record the latency to fall for each animal in a designated log or data
collection sheet. * Include relevant details like animal ID, weight, and any observations during
testing.

8. Post-Testing

8.1 Animal Recovery * Return the animal to its home cage after testing. * Monitor the animal
for any signs of distress and provide veterinary care if necessary.

8.2 Apparatus Cleaning * Clean the rotarod arena and lanes with disinfectant after each
testing session.

9. Maintenance

● Perform regular maintenance checks on the rotarod apparatus to ensure proper functioning.
● Report any malfunctions or need for repairs to the designated personnel.

10. Reference Documents

● IACUC protocol approval for your specific rotarod experiment.

● Manufacturer's instructions for the rotarod model being used.

11. Additional Notes

● This SOP is a general guideline and specific details may vary depending on the rotarod
model, animal species, and your research objectives.
● Always refer to your IACUC protocols and institutional guidelines for animal care and use
during rotarod testing.
Standard Operating Procedure (SOP) for Student Simulator Use

1. Purpose

This SOP outlines the procedures for safe, effective, and ethical use of the student simulator
within the learning environment.

2. Scope

This SOP applies to all students, instructors, and staff who will be interacting with the student
simulator during simulations.

3. Responsibilities

● Students:
○ Follow this SOP for proper use of the student simulator.
○ Treat the simulator with respect and avoid causing any damage.
○ Report any malfunctions or issues with the simulator to the instructor immediately.
● Instructor:
○ Ensure students are familiar with this SOP before using the simulator.
○ Supervise student use of the simulator and provide guidance.
○ Maintain the simulator in good working condition and report any maintenance needs.
● Staff:
○ Assist instructors in setting up and maintaining the simulator environment.
○ Ensure a clean and safe learning environment for simulation activities.

4. Pre-Simulation

4.1 Instructor: * Review the learning objectives for the simulation scenario. * Prepare the
simulation environment based on the scenario requirements. * Brief students on the scenario,
including patient condition, roles, and expected behaviors. * Instruct students on the
functionalities and limitations of the simulator.
