Summary
This study found no significant difference in pain perception between concentric and monopolar needle electrodes. However, participants reported lower pain scores with their preferred needle type.
Area of Science:
- Neurology
- Pain Management
- Electrophysiology
Background:
- Needle selection in electrodiagnostic studies can influence patient comfort.
- Understanding pain perception differences between needle types is crucial for patient-reported outcomes.
Purpose of the Study:
- To compare pain perception between concentric needle electrodes and monopolar needle electrodes in healthy females.
- To assess needle preference and its correlation with reported pain.
Main Methods:
- Prospective randomized study involving 80 healthy female participants.
- Biceps and abductor pollicis brevis (APB) muscles were tested with both needle types.
- Pain was measured using a verbal analog scale (0-10); needle preference was recorded.
Main Results:
- No significant difference in mean pain scores between concentric (3.06) and monopolar (3.10) needles (P=.803).
- Abductor pollicis brevis (APB) muscle was significantly more painful than biceps (P<.001).
- Lower pain scores were reported for the preferred needle type (P<.20).
Conclusions:
- Concentric and monopolar needle electrodes elicit similar pain perception in healthy females.
- Patient preference for a needle type may correlate with lower reported pain.
- Further research could explore factors influencing needle preference.

01:24Local Anesthetics: Differential Sensitivity of Nerve Fibers
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
01:29Blood and Nerve Supply to the Bones
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
