Prevalence and Incidence of Hand Osteoarthritis and Upper Limb Complaints in Patients with Knee Osteoarthritis. Correlations among Functionality, Grip Strength, Changes in Body Mass Index and Symptoms among Patients in an Educational Osteoarthritis Program ()
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 < 0.05) or symptoms at baseline and
reassessment (p < 0.05). Pinch strength (right and left tripod and left
pulp-pulp) was higher in patients without symptoms at baseline (p = 0.048, p =
0.045 and 0.033, respectively). Conclusions: The prevalence of hand OA
increased for patients with OA undergoing an educational program irrespective
of improved upper function and regardless of BMI change. Patients who decreased
their BMI improved their global strength.
