　View Summary

This study examined the ability of 63 subjects to discriminate a length difference, using a precision grip with the thumb and the index finger. To assess the relative contribution of different peripheral inputs associated with the discriminative ability of precision grip, three tasks were performed under each of three conditions - normal conditions when vibratory stimuli were delivered to the forearm muscles and when a local anesthetic was administered to the index finger. Under the first and second conditions, the length difference detected most frequently was 2.0 mm in the third task, it was 3.0 mm. When a 100-Hz vibratory stimulus was applied to the forearm muscles, no difference in the threshold for length discrimination was observed for three of seven subjects. After injection of lidocaine into the metacarpophalangeal joint of the index finger, the threshold for length discrimination was significantly different for five of seven subjects. The detected length difference ranged from 1.0 to 4.0 mm. The authors question whether a single peripheral input is likely to make a major contribution to the complex perception that is used for discrimination tasks.

　View Summary

Finger movements have primarily been classified by the final position of the hand and finger during deliberate hand activities, rather than as a description of the movement process. In addition, as of yet there have been no reports based upon objective data from the analysis of the motion of three finger joints during movement, nd no reports exist that describe the relationship of the three joints' motion during these movements. This paper describes the relationship of the three finger joints during simple finger movements and hand tasks using measurements and analysis from a two-dimensional motion analyzer. Two prehensile movements were examined in 15 healthy volunteers: pure finger extension from finger Flex position in different wrist positions (dorsi-flexion position, neutral position and palmar-flexion position of the wrist joint) and the grasping of discs of different diameter (10, 11, 12 and 13 cm). In the sequence of pure finger extension, where the grasping task was not requested, results showed that the movement was started from the proximal joint and extended to the distal joint of the finger, and full finger extension accomplished from distal to proximal, one after another, in any wrist position in most subjects. With the grasping of a disc, however, joint movement was initiated from distal to proximal and the final motion for grasping was carried to completion from the proximal to distal joints of the finger in most subjects. In addition, it was recognized that the proportion of the angular change in each of the three joints was different, as were the lime duration of the joint motion and the pattern of the angular change. From these results, it is suggested that deliberate activities of the finger and sophisticated joint movements provided delicate adjustments to fit the fingers to the size of the object, as compared to the simple finger extension movement.
