Abstract
This study aims to test the accuracy of the 10% rule. The 10% rule is a concept used by therapists in setting goals for patients with hand injuries, and states that the dominant hand has 10% greater strength than the nondominant hand. The difference between crushing grip strength of dominant and nondominant hands is related to the wrist circumference. This study included 43 athletes ages 18-22 attending Carthage College.. Athletes were tested for left and right hand crushing grip and pinch strength. They were classified into categories based on how far their fingers could wrap around the circumference of their wrist. The instruments used were a hand dynamometer, pinch gauge, and measuring tape. Anticipated results are that the grip strength of the dominant hand of small wrists will be greater compared to the nondominant hand. Medium wrists should have the least change in grip strength between hands; while, large wrists will fall in the average distribution of grip strength between hands.
