まとめ
腰椎椎間板ヘルニア(LDH)における運動回復には、早期の手術介入と術後1日目の筋力改善が鍵となる。神経根性疼痛の軽減と術前の重度の脱力低下も予後を改善する。
科学分野:
- 脳神経外科学; 整形外科学; 臨床転帰研究
背景:
- 運動神経障害を伴う腰椎椎間板ヘルニア(LDH)は、臨床的に重大な課題である。機能を回復させ、症状を緩和するために、しばしば外科的介入が必要とされる。
研究 の 目的:
- 運動神経障害を伴うLDHの手術治療を受けた患者の転帰を決定すること。手術後の完全な運動回復に関連する要因を特定すること。
主な方法:
- 運動神経障害(MRCスコア≤3)を伴うLDH患者144人を対象とした前向き観察研究。患者は術前、術後1日目、および1〜3ヶ月と10〜12ヶ月で評価された。完全な運動回復はMRCスコア5と定義された。
主要な成果:
- 患者の58%(144人中83人)が完全な運動回復を達成した。早期治療(10日増加あたり)、術前の脱力低下、術後1日目の神経根性疼痛の消失、術後1日目の筋力増加が回復と独立して関連していた。完全な運動回復は感覚回復とも関連していた。
結論:
- 術後1日目の筋力改善は、完全な運動回復の最も強力な予測因子である。神経根性疼痛の軽減、治療までの時間の短縮、術前の筋力向上などの要因が予後に影響を与える。これらの所見は、LDH手術の潜在的な転帰の理解において、臨床医と患者を支援する。

Attention-Deficit/Hyperactivity Disorder
1.0K
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Motor Units
62.0K
A motor unit consists of two main components: a single efferent motor neuron (i.e., a neuron that carries impulses away from the central nervous system) and all of the muscle fibers it innervates. The motor neuron may innervate multiple muscle fibers, which are single cells, but only one motor neuron innervates a single muscle fiber.

Motor Units
8.2K
The motor unit is a fundamental component of the neuromuscular system and plays a crucial role in coordinating muscle contractions. It consists of a somatic motor neuron, which connects and controls multiple skeletal muscle fibers, forming a single functional segment. The axon of the motor neuron branches out and establishes synaptic connections known as neuromuscular junctions with individual muscle fibers within the motor unit.

Real Number System
1.2K
The real number system includes all numbers used for counting, measuring, and comparing quantities. Natural numbers are the basic counting numbers: 1, 2, 3, and so on. Integers expand this set by including zero and negative whole numbers: ..., –3, –2, –1, 0, 1, 2, .... Rational numbers are those that can be expressed as the ratio of two integers m/n, where n≠0. This includes fractions like 1/2, integers such as 46, and decimals that terminate, such as 0.17, or...

Motor Unit Stimulation
3.9K
When the neuron of a motor unit fires an action potential, it triggers a series of events, leading to a twitch contraction in the muscle fibers. The process of excitation-contraction coupling is crucial in relaying the action potential to the muscle fibers.
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...

Hierarchy of Motor Control
6.3K
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.
