ABSTRACT: Objective: To evaluate
the prevalence of hand osteoarthritis (hOA) in a population with knee osteoarthritis
(KOA) at baseline and one year following the administration of a
multi-professional OA educational program correlating symptoms and changes in
BMI with function questionnaires of the upper limbs and direct grip strength
measurements. Design: Epidemiological study of the prevalence of hand OA in
patients with knee osteoarthritis. The Stanford Health Assessment Questionnaire
instruments (HAQ); Disabilities of the Arm, Shoulder and Hand* (DASH); grip
strength; and finger pinch were utilized, and the upper limbs symptoms were
verified at baseline and one year following the educational program. Results:
The prevalence of hOA was 23.7% at baseline and 47.4% at one year (incidence of
31.8% per year). The HAQ indicated that patients who did not alter or increased
their BMI experienced worsened global strength, whereas patients who reduced
BMI improved global strength (p = 0.041). Patients with higher initial BMIs
experienced less improvement in the HAQ (r = -0.148, p = 0.041). The DASH
results improved, but the right and left tripod grip worsened in all patients,
irrespective of BMI change (p
