“…Their progress was assessed by means of the following tests: pain on a visual analogue scale (Huskisson, 1974;Scott & Huskisson, 1976), articular index of joint tenderness (Ritchie, Boyle, McInnes, Jasani, Dalakos, Grieveson & Buchanan, 1968), grip strength in each hand (Deodhar, Dick, Hodgkinson & Buchanan, 1973;Lee, Baxter, Dick & Webb, 1974), digital joint circumference (Webb, Downie, Dick & Lee, 1973), duration of morning stiffness (limbering up time) and functional index (Lee, Jasani, Dick & Buchanan, 1973). These assessments were made by an independent assessor (MM) who routinely did the assessments ofall patients at the Rheumatic Centre, and were made at the initial visit and thereafter at monthly intervals for the 3 months of the trial.…”
