Description

Applying constrictive force on the forearm using an air pressure cuff creates a weight sensation. To identify the source of phantom sensation, we compared the weight sensation and EMGs of the forelimb between when a wrist joint was rotated, an elbow joint was rotated, and both the joints were rotated. The result showed that participants did not felt the weight sensation when only a wrist joint was rotated. Increased activity of biceps brachii by placing pressure on the distal part of a forearm indicates that neither a mechanical constraint of a wrist joint rotation nor a constraint of forearm muscles by the cuff caused the weight sensation.
