Background
Symptoms and psychosocial factors are suggested to account for more of the variation in disability than physical impairment, but perhaps less so at the level of specific tasks. This study assessed the influence of impaired wrist motion on specific tasks on the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire.
Methods
Sixty-three patients with an operatively treated fracture of the distal radius completed the Pain Catastrophizing Scale (PCS), Pain Anxiety Symptoms Scale, and Center for Epidemiologic Studies Depression Scale (CES-D) just before surgery and the DASH questionnaire 3 months after surgery. Nine questions on the DASH were selected as potentially sensitive to changes in wrist motion and evaluated in bivariate and multivariable analyses.
Results
In multivariable models of factors associated with specific tasks, only “Open a tight or new jar” was affected by wrist flexion and PCS accounting for 33 % of the variation. Motion, pain, and PCS were significant predictors of the DASH score. Among the eight tasks not related to wrist motion, 33 % of the variation in disability with writing was accounted for by PCS and limb dominance; 20 % of disability preparing a meal by pain, CES-D, and PCS; 14 % of disability with making a bed by pain and CES-D; and 23 % of changing a light bulb overhead by age, pain, and fracture type.
Conclusions
After volar plate fixation of a fracture of the distal radius, upper extremity disability based on select items from the DASH questionnaire correlated minimally with impairment of wrist motion, even at the level of specific tasks.
Level of Evidence
Prognostic Level II.
