- 溶接作業中に筋肉の活動を減らすためのIronHand®外骨格の有効性を評価するために.
- 外骨格がタスクの受容性と参加者の経験に与える影響を評価する.
- 外骨格介入の結果に対する個々の変動の影響を調査する.
主な方法:
- 筋肉の活動は,IronHand®エクソスケルトンを使用して,または使用せずに,溶接作業中に測定されました.
- タスクの許容性は,不快感後の要因の評価 (APDFs) を使用して評価されました.
- 利益と経験に関する参加者のフィードバックが収集されました.
主要な成果:
- IronHand®は,溶接作業中に筋肉の活動が少なからず減少した.
- このタスクは,エクソスケルトン (外骨格) を使った場合も,使わなかった場合も,受け入れられるままでした.
- 参加者の利益と経験において,個別の大きな違いが観察されました.
結論:
- IronHand®エクソスケーレットは,この溶接アプリケーションで筋肉の活動減少に限られた利点を提供しました.
- 手を狙うエクソスケレットは,肩や背中を狙うエクソスケレットよりも効果が低いかもしれません.
- 外骨格の設計と適用を最適化するために,手中の力分布に関するさらなる研究が必要である.

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...

01:16Muscles 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...

6.1K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

01:48Classification of Skeletal Muscle Fibers
59.6K
Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
