Abstract

OBJECTIVE:

To assess the relationship between muscle strength (Jama), and pain (VAS) levels with hand function (DASH) in patients with trapeziometarcapal osteoarthritis. Cross-sectional study.

PARTICIPANTS:

Sample of 72 patients with osteoarthritis stage 2-3 (Eaton) and trapeziometacarpal osteoarthritis. Patients were recruited when they came to the Hand Surgery Unit.

METHOD:

Grip strength, pinch, pain and hand function were measured, and correlation and regression coefficients between them were obtained.

RESULTS:

For function, the most significant model (R(2)=0.83) included pain and strength. But it is tip to tip pinch force which has a stronger relationship with DASH (Standardized B: -57) questionnaire. Pain also influenced strength measured with the dynamometer but it was tip to tip pinch force that was the most affected.

CONCLUSIONS:

Findings confirm that there is a significant correlation between function referred by the patient and variables that can be measured in the clinic such as grip strength and pinch. The correlation between pain intensity and function was also significant, but tip to tip pinch strength had the greatest impact on the function.
