- 腕筋の損傷は,肩と肘の機能に大きく影響を与えます.
- 回復には,軸索再生と中枢神経系 (CNS) の神経可塑性が含まれます.
- 神経可塑性を評価するための現在の神経イメージング方法は,臨床的有用性が限られています.
研究 の 目的:
- 神経移植外科手術後の神経可塑性マーカーを評価するための再現可能で低コストな方法として,針電気ミオグラフィ (EMG) を評価する.
- 機能的回復と再内化とシンキネーシスのEMGの発見を相関させるため.
- トラウマ性腕筋損傷からの回復を追跡する際にEMGの臨床的有用性を調査する.
主な方法:
- 腕筋の損傷のために34の近辺神経移植を受けた21人の患者を対象とした長期的観察研究.
- 連続EMGは,自発的な活動,モーターユニットポテンシャル,およびシンキネゼスを評価するために,≥36ヶ月間にわたって実施されました.
- MRCスケール,ゴニオメトリー,マレットスケール,DASHアンケートを使用して評価された機能的アウトカム.
主要な成果:
- 機能的成功 (MRC ≥3/5) は,神経移植の58.8%で達成されました.
- 早期再内化 (<6ヶ月) は53%で観察され,筋肉の強さの増加と相関していました (Rs = 0.53,p < 0.01).
- シンキネシスの解消は29%で発生し,手術までの時間 (Rs = -0.50,p = 0.005) と負の相関関係があり,シンキネシスの欠如はより良い結果と関連しています.

Neuroplasticity
1.9K
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

Holter Monitor: 24-Hour Monitoring
2.8K
Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...

Self-Presentation: Self-Monitoring and Self-Handicapping
44.8K
People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Self-monitoring is a central construct in understanding individual differences in self-presentation strategies across social contexts. It refers to how individuals observe, regulate, and control their expressive behavior and self-presentation following situational cues. Self-monitoring reflects a person's sensitivity to social appropriateness and willingness to adapt behavior to fit varying interpersonal demands.High vs. Low Self-Monitoring IndividualsIndividuals high in self-monitoring are...

Therapeutic Drug Monitoring: Affecting Factors
252
Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.

Errors occurring during blood pressure monitoring
1.5K
Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.
