The effect of hand osteoarthritis on grip and pinch strength and hand function in postmenopausal women

The aim of the study was to investigate the effect of osteoarthritis on hand function in postmenopausal women. One hundred patients with hand OA and 70 healthy volunteers as controls were evaluated. Grip and pinch strength measurements and Dreiser's functional index were used for hand function. Pain was assessed by a visual analog scale, and tenderness was assessed by palpation and scored, depending on the severity of tenderness, as 0, 1 or 2. Heberden's and Bouchard's nodules and joint involvement were also recorded. The number of patients with only distal interphalangeal joint involvement was 50 (50%), those with distal interphalangeal joint plus proximal interphalangeal joint involvement was 49 (49%), and those with carpometacarpal joint involvement numbered 18 (18%). The incidence of Heberden's and Bouchard's nodules was 85% and 36%, respectively. Eighty-six (86%) patients were suffering from pain and 57 were found to have tenderness. Grip and pinch strength was significantly lower (p
