As such, only the tendons essential for the index finger flexion/extension and abduction/adduction are studied and mimicked in our design.
The third is the degree of vocal fold adduction, which reflects the degree to which the vocal folds are pressed against each other.
They also permit the finger to return to its original position after flexion/extension or abduction/adduction.
The design of the thumb differs from the fingers by allowing an adduction towards the index finger and an opposition towards the other fingers.
Occasional variants may occur, such as shoulder adduction or wrist supination.
Results were expressed in terms of flexion/extension, adduction/ abduction and internal/external rotation.
Adduction is controlled by a group of laryngeal muscles.
It determines the amplitude of the translottal air pulses, such that a high degree of glottal adduction results in short air pulses of low amplitude.
