Purpose: To evaluate the impact of trigger finger (TF) on hand motor function, activity and participation (A&P) and quality of life (QOL), and to evaluate the association between personal factors (age and gender, disease severity) and body functions (dexterity and strength) with A&P and QOL in patients with TF. Methods: Sixty-six patients with TF (study group) and 66 healthy volunteers (control group) participated in the study. TF symptoms were graded using the Quinnell classification. A&P was evaluated using the Disabilities of Arm Shoulder and Hand questionnaire and the QOL using the World Health Organization Quality of Life questionnaire. Dexterity was evaluated using the Functional Dexterity Test and the Purdue Pegboard Test; hand strength was evaluated using the Jamar Dynamometer and Pinch Gauge. Results: The comparisons between the study and control groups revealed significant differences in all measures. The study group reported lower perceived QOL, A&P and reduced hand strength and dexterity. Hierarchical regression analyses revealed that (a) the severity of TF contributed significantly to the explained variance of QOL, while demographics and hand functioning did not; (b) demographics, TF severity and hand function all contributed significantly to the explained variance of A&P. Conclusion: The findings of the study point to the importance of addressing the functional implications and QOL of individuals with TF. Implications for Rehabilitation Although trigger finger is considered to be a mild hand pathology, it has a wide-ranging impact on hand functioning, daily activities and quality of life. Clinicians should include assessments of these outcomes in the treatment of individuals with trigger finger. Treatment efficacy should be evaluated with International Classification of Functioning outcomes, and not limited to symptomatology.
