There are five main types of grasp that the thumb performs: cylindrical grasp, tip pinch, palmar grasp, spherical grasp, and lateral pinch. (4)
Typical strength measurements include grip strength, lateral pinch strength, and palmar (tripod) pinch strength.
Lateral pinch strength is commonly used to open a container lid or bag of food and access the contents [1,2].
Both prototypes supported the use of up to six preprogrammed grip patterns: power grip, tool grip, chuck grip, lateral pinch, fine pinch open, and fine pinch closed.
Lateral pinch strength measurements were done with the palm facing medially while force was exerted between the pad of the thumb and the opposing lateral side of the middle phalanx of the index finger through the opposing surfaces.
They reported 95% of 22 patients studied as having excellent pain relief and satisfaction, even with activities that required significant lateral pinch (i.e.
For example, he had lateral pinch strength of 4.5 pounds at 5-year follow-up, compared with 4 pounds at 4 years; and his two-point pinch strength was 3 pounds at 5 years, compared with 1 pound at 4 years.
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.
Results of the lateral pinch grip strength assessment showed that pinch width had a significant effect on pinch force, with the average (across participants) force increasing from 1 to 5 cm, peaking at 5 cm, and declining at the 7-cm grip span.
The lateral pinch applies force between the thumb and index finger and uses muscles other than those in the tunnel.
However, it would be beneficial to evaluate the lateral pinch force in future studies.
