Summary
This bibliometric study reveals a growing trend in research on transcranial direct current stimulation (tDCS) for pain management. The analysis highlights key journals, prolific authors, and emerging keywords, offering insights for future pain research.
Area of Science:
- Neuromodulation
- Pain Management
- Bibliometrics
Background:
- Chronic pain management remains a significant clinical challenge.
- Transcranial direct current stimulation (tDCS) is a recognized neuromodulation technique for chronic pain.
- Understanding publication trends in tDCS for pain is crucial for advancing research.
Purpose of the Study:
- To conduct a bibliometric analysis of research articles on pain and tDCS.
- To provide a visualized overview of publication trends and identify key contributors.
- To stimulate new research ideas for clinicians in pain management.
Main Methods:
- A systematic retrieval of articles on pain and tDCS from the Web of Science database.
- Quantitative and statistical analysis using R software (version 4.1.2) and the 'biblioshiny' package.
- Visualization of publication time trends, author contributions, institutional affiliations, and citation metrics.
Main Results:
- Analysis of 554 publications shows a consistent increase in scientific output, with 17.1% annual growth.
- Brain Stimulation Journal and Journal of Pain are leading publications; Fregni F. is the most prolific author.
- USA leads in author involvement, Universidade Federal Rio Grande Do Sul leads in institutions; 'osteoarthritis' and 'low back pain' are trending keywords.
Conclusions:
- This is the first bibliometric study mapping the trends of tDCS in pain management.
- Despite a concentrated authorship and journal base, the increasing volume of publications and citations indicates tDCS is an emerging area in pain research.
- The findings provide a foundational basis for future research and development in pain management strategies using tDCS.

01:25Calculation of Electric Flux
Consider the electric field of an oppositely charged, parallel-plate system and an imaginary box between those plates. Let the bottom face of the box be ABCD, and the top face be FGHK. The electric field between the plates is uniform and points from the positive plate toward the negative plate. The calculation of this field's flux through the box's various faces shows that the net flux through the box is zero. Why does the flux cancel out here?
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...

01:10Nodal Analysis
Nodal analysis is a fundamental method in electrical engineering used to simplify the process of circuit analysis. This method revolves around the concept of using node voltages as the primary variables for circuit analysis. The objective is to determine the voltage at each node in a circuit, which can then be used to find other quantities of interest, such as currents through specific components.
Consider, for instance, a simple circuit composed of three nodes and three resistors, as shown in...

01:14Node Analysis for AC Circuits
Consider an angioplasty system featuring a catheter equipped with a turbine, a critical tool for removing plaque deposits from coronary arteries. This intricate medical device operates using a circuit model reminiscent of a dual-node RLC circuit powered by a current-controlled voltage source.
To unravel the complexities of this system, nodal analysis is employed, a powerful technique founded on Kirchhoff's current law (KCL), which remains valid for phasors. AC circuits can effectively be...

01:22Series R—L Circuit Transients
In a series resistor-inductor (R-L) circuit, closing the switch at the start of the time period simulates a three-phase short circuit, a fault condition where all three phases of an unloaded synchronous machine are short-circuited. When there is no fault impedance and no initial current, the initial voltage is determined by the phase angle of the source voltage.
Using Kirchhoff's Voltage Law (KVL) to analyze this circuit helps determine the total asymmetrical fault current, which consists of...

01:20Pain
Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...
