Finger and Tweezers Dexterity
O’Connor Finger and Tweezers Dexterity Tests:
O’Connor Finger and Tweezers dexterity was developed by Jonson O’Connor of General Electric Company in 1920s. Research in the past has demonstrated in the existence of a number of manual dexterities. This test measures Finger Dexterity which involves the ability to-coordinate finger movements in performing fine manipulations. Finger dexterity tests generally require grasping, releasing or manipulation of small objects in which the finger tips is primarily used. In the tweezerss dexterity tests the individual holds a pair of tweezerss in his preferred hand and performs manipulation of small pins.
The instrument contains a wooden or a metal board consists of two halves. …show more content…

The tray containing sufficient pins are kept on the side of individuals preferred hand. The individual is instructed to pick up one pin at a time with the help of the finger and begin to fill the holes in the board beginning left top for the right handed person (top right for left handed). Individual is instructed not to pick up the pins that are fallen. The holes are filled row-wise. A trial practice of filling two rows is given before actual start-up. Time taken to fill the 100 holes is measured in seconds. The number of seconds lapsing between the first and the last pin is taken. The higher the score, the lesser the efficiency in …show more content…

Tester provides an inexpensive Means to access activity level and attention capacity. The subjects task is to hold the stylus in nine different holes of diminishing size without touching the sides or base plate. Tester is fitted with a Fault counter. An audible tone and visual red indicator responses and provide immediate feed-back of performance.

Finger tapping Test:
The tapping rate is a psychological test given to assess the integrity of the neuromuscular system and examine motor control. The finger tapping test has the advantage of being a relatively pure neurologically driven motor task because the inertial and intersegment interactions are so small that biomechanical influences on movement are reduced. Finger tapping involves three important features: time, spatial amplitude, and frequency. Studies have reported that the average number of taps per 10-second interval can be used to distinguish between patients with mild traumatic brain injury and healthy controls, is slower in people one month after sustaining a mild traumatic brain injury,]and in experienced boxers and soccer players who frequently "headed" the ball. The speed of finger tapping has also been found to be related to severity of initial traumatic brain injury, and can be used to help assess recovery from mild and moderate traumatic brain injuries
