Study background: Carpometacarpal joint osteoarthritis has an important functional consequence on Activity daily life. Pain, is the main reason for medical consultation described in the literature. Last years, outcomes based on self-report of function and patient satisfaction have become variables increasingly important for measurement improvement.

Objective: Determinate the relationship between subjective variables (pain and function) and pinch and grip force in patients suffering from carpometacarpal joint osteoarthritis.

Methods: Observational analytic design. Final sample consisted of 72 patients diagnosis of carpometacarpal joint osteoarthritis, grade 2/3 Eaton. Pain, Grip and pinch force were measured and compared to patient-report functional outcomes (DASH).

Results: For function, the most significant model (R2=0.89) included grip, key, tip to tip and 3 points pinch. But it is tip to tip pinch force which has a stronger relationship with DASH (Standardized B: -736) questionnaire.

Conclusion: Function referred by the patient depends on pinch, grip force and pain, but is tip to tip pinch force the best predictor of function in a lineal correlation.
