Based on the evidence , aerobic capacity training combined with muscle strength training is recommended as routine practice in patients with RA
BACKGROUND An up-to- date overview of the effectiveness and safety of dynamic exercise therapy ( exercise therapy with a sufficient intensity , duration , and frequency to establish improvement in aerobic capacity and /or muscle strength ) is lacking .
OBJECTIVES To assess the effectiveness and safety of short-term ( < three months ) and long-term ( > three months ) dynamic exercise therapy programs ( aerobic capacity and /or muscle strength training ) , either l and or water-based , for people with RA .
To do this we up date d a previous Cochrane review ( van den Ende 1998 ) and made categories for the different forms of dynamic exercise programs .
Exercise can reverse quadriceps sensorimotor dysfunction that is associated with rheumatoid arthritis without exacerbating disease activity.
OBJECTIVES To compare quadriceps sensorimotor function , lower limb functional performance and disability in patients with rheumatoid arthritis ( RA ) and healthy subjects , and to investigate the efficacy and safety of a brief rehabilitation regime . METHODS Quadriceps strength , voluntary activation , proprioceptive acuity and the aggregate time [ aggregate functional performance time ( AFPT ) ] taken to perform four common activities [ aggregate functional performance time ( AFPT ) ] were compared between 103 RA patients who had lower limb involvement and 25 healthy subjects . In addition , disability ( Health Assessment Question naire ) , clinical disease activity and the plasma concentration of proinflammatory cytokines were measured in the RA patients . In a follow-on r and omized controlled trial of rehabilitation , these variables were used as baseline data for 93 of the RA patients , who were r and omized to a rehabilitation or a control group . Changes in the variables were analysed within and between groups . RESULTS Compared with healthy subjects , RA patients had weaker quadriceps [ mean difference 157 N ; 95 % confidence interval ( CI ) 125 - 189 ] , poorer activation ( 8 % , 95 % CI 4.5 - 15 ) and proprioceptive acuity ( 0.8 degrees , 95 % CI 0.4 - 1.3 ) and took longer to perform the AFPT ( 34 s , CI 23.5 - 44.8 ) . Rehabilitation increased quadriceps strength ( mean increase 61 N , 95 % CI 28 - 95 ) and voluntary activation ( 8 % , 95 % CI 3 - 12.4 ) and decreased the AFPT ( 12.3 s , 95 % CI -2 to 27.7 ) and subjective disability ( 0.21 HAQ points , 95 % CI 0 - 0.35 ) without exacerbating disease activity . All the improvements were maintained at the 6-month follow-up . There was no change during the control period . CONCLUSIONS Patients with RA that affected their lower limb had quadriceps sensorimotor deficits that were associated with lower limb disability . A clinical ly applicable rehabilitation regime increased quadriceps sensorimotor function and decreased lower limb disability without exacerbating pain or disease activity . For patients with well-controlled RA that causes lower limb involvement , the regime is effective and safe
