Objective:
We evaluated factors contributing to activity limitations in people with rheumatoid arthritis (RA) according to the International Classification of Functioning, Disability and Health model.
Method:
In a cross-sectional study, we measured five activity constructs in 81 people with RA.
Results:
Multiple regression analysis revealed the following results for the five constructs: (1) RA Activities (R² = .512) included handgrip strength, range of motion deficit, deformity, and mental health; (2) Upper-Limb Activities (R² = .473) included time since diagnosis, dexterity, handgrip strength, and range of motion deficit; (3) Timed Activities (R² = .320) included dexterity and work activities; (4) Physical Autonomy Activities (R² = .562) included range of motion deficit, vitality, pain, and functional classification; and (5) Physical Conditions for Activities (R² = .416) included functional classification and vitality.
Conclusion:
Factors most associated with activity limitations were handgrip strength and hand range of motion deficits. Activity limitations in people with RA are multifactorial.

Factors Affecting Activity Coefficient
The activity coefficient value for an ion is close to one when the solution has almost zero ionic strength, i.e., when the solution shows close to ideal behavior. As the ionic strength of the solution increases from 0 to 0.1 mol/L, a...
