主な方法:
- 4人の健康な被験者の動きを記録した,同時に表面と細いワイヤのEMGを記録する.
- イソメトリック前腕回転作業は,トルク抵抗を漸進的に増加させる.
- EMG信号分析は,フィルタリングと正規化後のルート平均平方値を用いて行います.
主要な成果:
- Supinatorは,supinationの間にバイセプス・ブラキアよりも高い初期活性化を示しました.
- バイセプス・ブラカイは,より高いトルクを持つスピナータよりも,比例的に活性化を増加させた.
- Pronator quadratusは,より低いプロネーショントルクでより活発であり,pronator teresはより高いトルクでより活発になりました.
- 複数関節の筋肉は,両運動のトルク要求の増加とともに徐々に採用されました.
結論:
- サピナーターとプロナーター・クアドラタスは,低トルク前腕回転のための主要な筋肉です.
- バイセプス・ブラキアとプロナーター・テレスは,トルクの要求が増加するにつれて,より支配的になります.
- 観察された階層的な採用は,メカニカル効率と関節の安定性を最適化し,リハビリテーションと義肢の臨床応用の可能性があります.

01:16Muscles that Move the Forearm
4.0K
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...

01:16Muscles of the Forearm that Move the Hand and Fingers
2.7K
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

01:23Functions of Smooth Muscles
3.5K
Smooth muscles are an important type of muscle tissue that plays a vital role in the involuntary movements of internal organs. For example, they help regulate the movement of food through the gut and the flow of blood through the circulatory system.
Function of visceral smooth muscles
Visceral smooth muscle is found in the walls of all hollow organs, except the heart, and is a key player in the involuntary movements that drive the functioning of these internal organs. This tissue is arranged in...

02:26Comparing Copy Number Variations and SNPs
18.8K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Animals have evolved different strategies for excretion, the removal of waste from the body. Most waste must be dissolved in water to be excreted, so an animal’s excretory strategy directly affects its water balance.

01:09Comparing Experimental Results: Student's t-Test
6.1K
The t-test is a statistical method used to compare the sample mean with a population mean or compare two means from two data sets. The test statistic is calculated from the standard deviation, mean, and number of measurements in the data set at a selected confidence interval and then compared to a table of critical values at this confidence level. If the test statistic is smaller than the critical value, the null hypothesis is accepted. In this case, we state that the difference between the...
