Background Hand osteoarthritis (OA) affects 51% of women over 65 years. The distal and proximal interphalangeal joints and the first carpometacarpal joints are usually involved. This leads to pain as well as functional impairment in terms of stiffness, reduced grip force and limitations on daily activities.

Objectives The objective of this study was to measure impairment in terms of grip force, extension force, pain and stiffness, in order to determine a threshold value of grip force indicative of impaired hand function and to assess patient-reported limitations in hand function.

Methods The study comprised 53 women with hand OA. Grip force was measured with the Grippit instrument, the extension finger force was measured with a recently developed instrument, Ex-it, while pain and stiffness were graded using a visual analogue scale. Hand activities were evaluated with Resht’s test and with the patient-reported Quick Disabilities of the Arm Shoulder and Hand (DASH) Questionnaire.

Results Women with a grip force below 104 N had significantly greater difficulties performing hand activities, and more pain and stiffness than women with a grip force above 104 N.

Conclusions A grip force of 104 N appears to provide a good indication for associations between hand function and hand activities. This threshold value could be useful in hand training, working outside home and designing of technical equipment.
