Summary
This study established normative nerve conduction study parameters for upper limb nerves in healthy adults in Central India. Gender influenced certain nerve conduction values, highlighting its importance in data interpretation.
Area of Science:
- Neuroscience
- Electrophysiology
- Clinical Neurophysiology
Background:
- Nerve conduction studies (NCS) are crucial for diagnosing peripheral nerve disorders.
- Establishing normative electrophysiological data is essential for accurate clinical interpretation.
- Previous studies may lack specific normative values for certain populations or geographic regions.
Purpose of the Study:
- To determine normative electrophysiological data for common upper limb nerves in healthy adults.
- To provide reference values for the Central India population.
- To assess the influence of gender on nerve conduction parameters.
Main Methods:
- Prospective nerve conduction studies were conducted on 175 healthy volunteers (aged 18-66).
- Standardized techniques were employed for testing median and ulnar nerves in the upper limbs.
- Data analysis focused on conduction velocity, amplitude, and latencies.
Main Results:
- No significant differences in motor median/ulnar nerve conduction velocity and amplitude, or median sensory conduction velocity.
- Gender significantly influenced ulnar nerve sensory amplitude and conduction velocity, and distal motor and F-minimum latencies for both median and ulnar nerves (P < 0.05).
- Established normative parameters for the Central India region.
Conclusions:
- This study provides essential normative nerve conduction data for upper limb nerves in Central India.
- Gender is a significant factor influencing specific nerve conduction parameters, requiring consideration in clinical assessments.
- These findings aid in the accurate evaluation of peripheral nerve abnormalities in the local population.

1.8K
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...

Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

01:12Arteries of the Upper Limbs
3.3K
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...
