Studies have indicated that the loss of palmar pinch reduced the probability of return to work, with or without changing specific job duties (Chang, Wu, Lee, Guo, & Chiu, 2011).
Woody and Mathiowetz (1988) found that while "scores were slightly higher in the pronated position for palmar pinch, they did not reach the 0.05 level of significance" (p.
When a person grips with their thumb, index and middle fingers, it is palmar pinch
. Finally, tip-pinch grip is performed with thumb and index fingers.
Palmar pinch strength is apparently important to hold a ball when throwing a fastball (16).
A pinch gauge (MG-4320NC pinch gauge; B & L) was used to measure tip, key and palmar pinch on both dominant and non-dominant sides.
Differences between dominant and non-dominant grip strength, tip, key and palmar pinch were compared using a paired sample t-test.
Grip strength and tip and palmar pinch strength and muscle mass of upper extremity in the dominant side were statistically greater than those of the non-dominant side.
A B&L pinch gauge was used in this study for the quantitative evaluation of tip, key and palmar pinch strength.
The majority of tip, key and palmar pinch scores was lower than normative scores for nearly all testing periods.
The Jamar[R] Hydraulic Pinch Gauge assesses finger tip, key, and palmar pinches in kilograms.
Statistically significant differences were found between the TOS patients and the referent group in the results of peripheral nerve function tests such as the median of the distal strength, lateral pinch and palmar pinch
of the hands, and vibrotactile thresholds.
