Abstract

© IMechE 2020. Hand arthritis is the leading cause of disability in individuals over the age of 50, causing impairments in grip strength and range of motion. Golf is often recommended to patients with hand arthritis as a low-impact sport to maintain a healthy lifestyle. As such, numerous “arthritic” golf grips have been marketed, but lack quantitative measures to justify their use. The objective of this study was to quantify the differences in total applied grip force in golfers with/without hand arthritis using several types of golf grips. Twenty-seven participants (17 without and 10 with hand arthritis) were evaluated swinging mid-iron clubs with 12 different golf grip designs (9 standard and 3 “arthritic”). The trail hand thumb, index, middle, and ring finger applied grip forces were measured using the wireless FingerTPS system. Finger grip configuration (finger joint angles) of the thumb and index were measured using the Dartfish Movement Analysis Software paired with the newly developed Grip Configuration Model to obtain grip range of motion. Results indicated that golfers with hand arthritis had a significant deficit of 45% golf grip strength (P = 0.02). In addition, individuals with hand arthritis exhibited larger forces in 11 out of 12 golf grips tested when compared with their maximum golf grip strength. Despite how these grips are marketed, there are no “savings” in finger force or grip configuration when using the “arthritic” designed golf grips. Therefore, these grips may not be beneficial for patients with hand arthritis.
