Ritchie index

Ritchie index

a widely used articular measurement for the assessment of joint tenderness in patients with rheumatoid arthritis. It is the sum of the grades of tenderness (0 = not tender, 1 = tender, 2 = tender and causes wince, and 3 = tender, causes wince and effort to withdraw) elicited by applying firm pressure over the joint margin of articular joints (for example, shoulders, elbow, wrists, hips).

Primary outcome measures were pain while walking and standing and at rest during the previous 24 hour, recorded on a 100 mm Visual Analogue Scale (VAS) and pain or tenderness, produced under firm digital pressure and with movement of the affected knee, scored according to Doyle's Ritchie Index on a 4-point scale (0=no tenderness, 1=patient complained of pain, 2=patient complained of pain and winced, 3=pain, wincing leading to withdrawal) (12,13).

In addition, baseline Ritchie index, VAS score at rest, walking and at standing position, and total WOMAC scores of the patients were not statistically different between the groups (Table 1).
