Foot pain Rheumatoid arthritis
Three RCTs [ 13 ], [ 19 ], [ 21 ] and one prospective observational study [ 22 ] measured foot pain in people with rheumatoid arthritis . One RCT [ 13 ] compared traditional therapeutic footwear to a newer therapeutic footwear designed with patient and practitioner input . After 12 weeks , significant between group improvement was observed for the newer therapeutic footwear group compared to the traditional therapeutic footwear group ( d : 0.92 – 1.26 ; large effect ). Significant within group improvement in foot pain was observed in the newer therapeutic footwear group ( d :
1.08 – 1.24 ; large effect ), with no significant improvement in the traditional therapeutic footwear group ( d : 0.18 – 0.19 ; negligible effect ). Another RCT [ 19 ] compared three footwear conditions ; extra-depth footwear only , extradepth footwear with soft foot orthoses and extra-depth footwear with semi-rigid foot orthoses . At 12 weeks , significant between group reductions in MTP pain was reported in the extra-depth footwear with semi-rigid orthoses group compared to the footwear with soft orthoses group ( d = 0.45 ; medium effect ) and footwear only group ( d = 0.78 ; medium effect ). There was no significant within group improvement observed in the footwear with soft orthoses and footwear
