Top 5 Mistakes in Electrotherapy Practical Exams — And How to Avoid Them

Electrotherapy practicals can be tricky, especially when you're under time pressure. Even good students often lose marks due to small, avoidable errors. Here's a quick guide to the Top 5 mistakes students make in electrotherapy practical exams — and how you can avoid them!

---

❌ 1. Skipping Safety Checks

Mistake: Not inspecting the machine, cables, or checking for contraindications before starting.

How to Avoid:
✅ Always begin with:

• Checking power supply

• Inspecting wires/electrodes

• Asking patient about pacemaker, metal implants, pregnancy, or sensation issues

💡 Bonus Tip: Verbally say, "I’m checking for contraindications," — examiners love that!

---

❌ 2. Wrong Electrode Placement

Mistake: Placing electrodes randomly or without clinical reasoning.

How to Avoid:
✅ Follow correct patterns:

• TENS – Over pain area or dermatomes

• IFT – Crisscross around pain

• SWD – Symmetrical on either side with proper spacing

💡 Pro Tip: Explain why you’re choosing that placement during the demo.

---

❌ 3. Incorrect Parameter Settings

Mistake: Setting frequency, intensity, or pulse width incorrectly — or forgetting to set them at all.

How to Avoid:
✅ Know your standard ranges:

• TENS: 50–100 Hz (acute), 2–10 Hz (chronic)

• IFT: Beat freq 90–130 Hz (pain), 0–10 Hz (edema)

• Faradic: Pulse duration ~0.1–1 ms, freq 50 Hz

💡 Tip: If unsure, say the values out loud while setting to show clarity.

❌ 4. Not Communicating with the Patient

Mistake: Starting treatment without informing or checking with the patient.

How to Avoid:
✅ Always:

• Explain the procedure

• Describe the sensation they should feel

• Ask for feedback after increasing intensity

💡 Golden Line: “Let me know if you feel any discomfort or burning.”

---

❌ 5. Forgetting Aftercare & Cleanup

Mistake: Ending session without turning off the machine, removing electrodes properly, or cleaning.

How to Avoid:
✅ Always:

• Turn off the unit before disconnecting

• Gently remove electrodes

• Clean the area and equipment

• Thank the patient

💡 Pro Tip: Say “Now I’ll clean the electrodes and check for any skin irritation.” Shows professionalism!
