Hand disability related variables in an Egyptian female RA patients sample

The aim of the present work is to study hand affection in Rheumatoid Arthritis [RA] in an Egyptian female sample to establish a map of lesions underlying the rheumatoid hand dysfunction using clinical, laboratory and imaging techniques. This study comprised 100 adult female RA patients. They were clinically assessed for pain using visual analogue scale [VAS], joint tenderness using Ritchie Articular Index, assessment of grip strength, assessment of functional ability using Health Assessment Questionnaire [HAQ], and assessment of hand function using Sequential Occupational Dexterity Assessment score [SODA] patients were subjected to the following laboratory investigations: full blood picture, ESR, C-reactive protein concentration and rheumatoid factor. Radiological investigations included plain X-ray examination and Magnetic resonance imaging. SODA score for hand dexterity had highly significant correlations with disease duration, morning stiffness, ESR, Ritchie index, VAS, HAQ, Duke index disease activity, and hand grip [p<0.001 for all]. It was significantly higher in patients with muscle wasting, deformity and tenosynovitis of the hand, moreover, it showed highly significant correlations with X-ray score and MRI scores. SODA score for hand dexterity had highly significant correlations with clinical findings. SODA score is valuable for evaluation of hand disability and disclosure of the underlying clinical, laboratory and imaging variables in RA female patients
