まとめ
この研究では 痛みの神経科学教育 (PNE) と組み合わせた 経頭部直流刺激 (tDCS) が 繊維筋痛と三頭神経痛を 効果的に治療することが示されました 統合されたアプローチは 痛み,疲労,認知感情的症状を改善しました
科学分野:
- 神経調節
- 痛みの管理
- 神経科学
背景:
- 線維筋痛 (Fibromyalgia, FM) と三頭神経痛 (Trigeminal neuralgia, TN) は慢性的な痛みの症状であり,多くの場合,認知的感情的障害と関連しています.
- これらの症状は しばしば誤って診断され 効果的な治療は困難です
研究 の 目的:
- 痛みの神経科学教育 (PNE) と併合したトランスクレニアル直流刺激 (tDCS) が,線維筋痛 (FM) と三角神経痛 (TN) の管理に有効性を調査する.
- 慢性疼痛の認知感情的および感覚的側面の両方にtDCS + PNEの影響を評価する.
主な方法:
- FMとTNと診断された22歳の女性患者を対象としたケーススタディ.
- 左側側頭前皮質を標的とした2mAのtDCSを20分間5回投与した.
- その後,毎回約20分のPNEで tDCSを行いました.
主要な成果:
- 患者はTNの症状が完全に解消し,一般的な痛み,疲労,敏感性が改善したと報告した.
- 自ら報告した痛み (60%),痛みが壊滅的になる (65%),運動恐怖症 (24%) および中央感受性 (28%) の有意な減少が観察されました.
- 介入後,注意の干渉は33%改善しました.
結論:
- tDCSとPNEの組み合わせは,FMとTNの管理に積極的な効果を示しました.
- 介入は認知感情領域を成功裏に標的とし,これと感覚の両方の改善につながりました.
- tDCS + PNEは,これらの困難な痛みを治療する新しい治療法となる可能性があります.

Nociception
28.4K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

Blood and Nerve Supply to the Bones
15.4K
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...

Local Anesthetics: Differential Sensitivity of Nerve Fibers
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...

Local Anesthetics: Clinical Application as Epidural Anesthesia
1.0K
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...
