The neural mechanisms underlying the sense of joint position and movement remain controversial. While cutaneous receptors are known to contribute to kinesthesia for the fingers, the present experiments test the hypothesis that they contribute at other major joints. Illusory movements were evoked at the interphalangeal (IP) joints of the index finger, the elbow, and the knee by stimulation of po...

Abstract The rotary table vibration of the spin coater directly impacts quality coating film. In view unclear characteristics during operation, and its influencing factors considering spindle system are studied. Based on elastic contact theory multi-body theory, when parts flexible analyzed by establishing multi-rigid body coupling dynamics models, respectively. By comparing with measurement re...

These experiments were designed to investigate illusions of movements of the fingers produced by combined feedback from muscle spindle receptors and receptors located in different regions of the skin of the hand. Vibration (100 Hz) applied in cyclic bursts (4 s 'on', 4 s 'off') over the tendons of the finger extensors of the right wrist produced illusions of flexion-extension of the fingers. Cu...

BACKGROUND AND AIMS It has not been clarified if botulinum toxin (BTX) injection leads to muscle spindle dysfunction in man. This study aimed to test the hypothesis that BTX application reduces the facilitation of a magnetic evoked response (MEP). METHODS We used the vibration induced facilitation of an MEP of the sternocleidomastoid muscle (SCM) as a surrogate marker for muscle spindle funct...

This study investigates machining stability considering the rotational and thermal effects of a spindle-bearing system. Conventional method for analysis only has regarded static response spindle system, which does not represent actual conditions as some investigations mentioned. Bearing stiffness change caused by contact angle is applied to analytical approach dynamics At same time, in frequenc...

The effect of hand muscle mechanical vibration on the somatosensory potential (SEP) evoked by median nerve stimulation, was investigated in 10 healthy subjects. A marked decrease in the amplitude of the N17, N20 and P25 components of the cerebral SEP was observed, while the S11 and S13 components of the cervical response did not change. The amplitude reduction of the SEP components was larger w...
