筋肉間移動による上肢の動きの解読: 合成データから臨床データへ
まとめ
ミオキネティック・プロテスの上肢の動きを 効率的に解読できるのは 筋肉ごとに1つの磁石 (1MM) です このアプローチは複数の磁石に匹敵する精度を提供し,手術の複雑性と計算の負荷を簡素化します.
科学分野:
- 生物医学工学

- 義肢
背景:
- ミオキネティック・インターフェースは ロボット用義肢の制御のために 埋め込まれた磁石を使って 筋肉の活動を解読します
- マグネットの数と位置を最適化することは,安定した制御信号に不可欠です.
- マグネットの量と外科的/計算上の複雑性の間のトレードオフは有益である.
研究 の 目的:
- 筋肉ごとに1つの磁石 (1MM) を使って上肢の動きを分類する可能性を評価する.
- 1MMのアプローチの分類精度を,2つの筋肉毎の磁石 (2MM) の方法と比較する.
- ミオキネティックなインターフェイスで1MMが正確な捉え方判別に十分かどうかを判断する.
主な方法:
- 前腕のモックアップに1MMと2MMのインプラントをシミュレートし,収縮中の筋肉間の移動を測定します.
- シミュレートインプラントのデータを用いて 複数の上肢の動きを分類した.
- 1MMのアプローチを検証した.
主要な成果:
- 筋肉毎の1つの磁石 (1MM) は,複数の握りを区別するのに十分な精度を示しました.
- 1MMアプローチは,筋肉内移転に匹敵する分類情報を提供した.

00:51Anatomical Movements
13.8K
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

01:31Muscles that Move the Arm
5.6K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

01:23Muscles that Move the Leg
6.9K
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...

01:28Muscles of the Leg that Move the Foot and Toes
5.1K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....
