    Input: Fernández-de-las-Peñas C , Alonso-Blanco C , Morales-Cabezas M , Miangolarra-Page JC : Two exercise interventions for the management of patients with ankylosing spondylitis : A r and omized controlled trial . Am J Phys Med Rehabil 2005;84:407–419 . Objective : The purpose of this clinical trial was to evaluate the impact of a 4-month comprehensive protocol of strengthening and flexibility exercises developed by our research group versus conventional exercises for patients with Ankylosing Spondylitis ( AS ) on functional and mobility outcomes . Design : R and omized controlled trial . Forty-five patients diagnosed with AS according to the modified criteria of New York were allocated to control or experimental groups using a r and om numbers table . The control group was treated with a conventional protocol of physical therapy in AS , whereas the experimental group was treated with the protocol suggested by our research group . The conventional intervention consisted of 20 exercises : motion and flexibility exercises of the cervical , thoracic , and lumbar spine ; stretching of the shortened muscles ; and chest expansion exercises . The experimental protocol is based on the postural affectation of the AS and the treatment of the shortened muscle chains in these patients according to the Global Posture Reeducation ( GPR ) method . This intervention employs specific strengthening and flexibility exercises in which the shortened muscle chains are stretched and strengthened . The study lasted 4 mos . During this period , patients received a weekly group session managed by an experienced physiotherapist . Each session lasted an hour , and there were 15 total sessions . Changes in activity , mobility , and functional capacity were evaluated by an assessor blinded to the intervention , using the following previously vali date d scores from the Bath group : BASMI ( tragus to wall distance , modified Schöber test , cervical rotation , lumbar side flexion , and intermalleolar distance ) , BASDAI ( The Bath Ankylosing Spondylitis Disease Activity Index ) , and BASFI ( The Bath Ankylosing Spondylitis Functional Index ) . Results : Both groups showed an improvement ( prepost scores ) in all the outcome measures , mobility measures of the BASMI index , as well as in BASFI and BASDAI indexes . In the control group , the improvement in tragus to wall distance ( P = 0.009 ) and in lumbar side flexion ( P = 0.02 ) was statistically significant . Although the rest of the outcomes also improved , they did not reach a significant level ( P > 0.05 ) . In the experimental group , the improvement in all the clinical measures of the BASMI index ( P < 0.01 ) and in the BASFI index ( P = 0.003 ) was statistically significant . The intergroup comparison between the improvement ( prepost scores ) in both groups showed that the experimental group obtained a greater improvement than the control group in all the clinical measures of the BASMI index , except in tragus to wall distance , as well as in the BASFI index . Conclusions : The experimental protocol developed by our research group , based on the GPR method and specific strengthening and flexibility exercises of the muscle chains , offers promising results in the management of patients suffering from AS . Further trials on this topic are required We investigated the effects of home-based daily exercise on joint mobility , functional capacity , pain , and depression in patients with ankylosing spondylitis ( AS ) . The patients were r and omly assigned to a wait-list control group or to an exercise-therapy group . The exercise-therapy group performed a 20-min exercise program once per day for 8 consecutive weeks . After 8 weeks , compared with the control group , the exercise group showed improvements in joint mobility ( cervical flexion , extension , shoulder flexion , abduction , hip abduction , and knee flexion ) , finger – floor distance , and functional capacity . Pain and depression scores were significantly lower after the exercise program in the exercise group than in the control group . These findings indicate that exercise therapy increases joint mobility and functional capacity , and decreases pain and depression in patients with AS .  Home-based exercise , which is easily accessible to patients , might be an effective intervention for AS AIM The aim of the study was to compare the effects of conventional exercise ( CE ) , swimming and walking on the pulmonary functions , aerobic capacity , quality of life , Bath indexes and psychological symptoms in patients with ankylosing spondylitis ( AS ) . METHODS Forty-five patients were r and omised into either swimming ( group 1 ) , walking ( group 2 ) , CE group ( group 3 ) . Patients in Group 1 performed CE and swimming , patients in Group 2 performed CE and walking and patients in Group 3 performed CE only . Exercise sessions were performed three times a week for a period of six weeks . Patients were assessed before and after the rehabilitation program , with respect to , pulmonary function test ( forced vital capacity [ FVC , mL ] , forced expiration volume in one second [ FEV1 , mL ] , FEV1/FVC ( % ) and vital capacity [ VC , mL ] ) , maximal oxygen uptake ( pV.O2 ) , 6-minute walking test ( 6MWT ) , Bath Ankylosing Spondylitis Functional Index , Bath Ankylosing Spondylitis Disease Activity Index , Bath Ankylosing Spondylitis Metrology Index , Nottingham Health Profile and Beck Depression Inventory . RESULTS There were significant increases in pVO2 and 6MWT after treatment in Groups 1 and 2 ( P<0.05 ) . FeV1 , FVC and VC improved significantly with treatment in all three groups ( P<0.05 ) . A statistically significant improvement was observed in energy , emotional reaction and physical mobility sub-scores of NHP in three exercise groups after completion of the exercise program ( P<0.05 ) . CONCLUSIONS Swimming , walking and CE had beneficial effects on the quality of life and pulmonary functions . Aerobic exercises such as swimming and walking in addition to CE increased functional capacities of patients The optimal management of ankylosis spondylitis ( AS ) involves a combination of nonpharmacologic and pharmacologic treatment aim ing to maximize health-related quality of life . The primary objective of our study was to demonstrate the benefits of an original multimodal exercise program combining Pilates , McKenzie and Heckscher techniques on pulmonary function in patients with AS , while secondary objectives were to demonstrate the benefits of the same program on function and disease activity . This is a r and omized controlled study on ninety-six consecutive patients with AS ( axial disease subset ) , assigned on a 1:1 rationale into two groups based on their participation in the Pilates , McKenzie and Heckscher ( group I ) or in the classical kinetic program ( group II ) . The exercise program consisted of 50-min sessions performed 3 times weekly for 48 weeks . St and ard assessment s were done at week 0 and 48 and included pain , modified Schober test ( mST ) and finger – floor distance ( FFD ) , chest expansion ( CE ) and vital capacity ( VC ) , as well as disease activity Bath Ankylosing Spondylitis Disease Activity Index ( BASDAI ) , functional Bath Ankylosing Spondylitis Functional Index ( BASFI ) and metrology index Bath Ankylosing Spondylitis Metrology Index ( BASMI ) . Groups were comparable at baseline ; we demonstrated significant improvement between baseline and after 48 weeks of regular kinetic training for all AS-related parameters in both groups . However , significant improvement was found in pain , lumbar spine motility ( mST , FFD ) , BASFI , BASDAI and BASMI in AS performing the specific multimodal exercise program at the end of study ( p = 0.001 ) . Although there were significant improvements in CE in both groups as compared to baseline ( group I , p = 0.001 ; group II , p = 0.002 ) , this parameter increased significantly only in group I ( p = 0.001 ) . VC measurements were not significantly changed at the end of the study ( group I , p = 0.127 ; group II , p = 0.997 ) , but we found significant differences within groups ( p = 0.011 ) . A multimodal training combining Pilates , McKenzie and Heckscher exercises performed regularly should be included in the routine management of patients with AS for better control of function , disease activity and pulmonary function Objective : To vali date and refine two sets of c and i date criteria for the classification/diagnosis of axial spondyloarthritis ( SpA ) . Methods : All Assessment of SpondyloArthritis international Society ( ASAS ) members were invited to include consecutively new patients with chronic ( ⩾3 months ) back pain of unknown origin that began before 45 years of age . The c and i date criteria were first tested in the entire cohort of 649 patients from 25 centres , and then refined in a r and om selection of 40 % of cases and thereafter vali date d in the remaining 60 % . Results : Upon diagnostic work-up , axial SpA was diagnosed in 60.2 % of the cohort . Of these , 70 % did not fulfil modified New York criteria and , therefore , were classified as having “ non-radiographic ” axial SpA. Refinement of the c and i date criteria result ed in new ASAS classification criteria that are defined as : the presence of sacroiliitis by radiography or by magnetic resonance imaging ( MRI ) plus at least one SpA feature ( “ imaging arm ” ) or the presence of HLA-B27 plus at least two SpA features ( “ clinical arm ” ) . The sensitivity and specificity of the entire set of the new criteria were 82.9 % and 84.4 % , and for the imaging arm alone 66.2 % and 97.3 % , respectively . The specificity of the new criteria was much better than that of the European Spondylarthropathy Study Group criteria modified for MRI ( sensitivity 85.1 % , specificity 65.1 % ) and slightly better than that of the modified Amor criteria ( sensitivity 82.9 , specificity 77.5 % ) . Conclusion : The new ASAS classification criteria for axial SpA can reliably classify patients for clinical studies and may help rheumatologists in clinical practice in diagnosing axial SpA in those with chronic back pain . Trial registration number : NCT00328068 Objective . To evaluate the effect of combining incentive spirometer exercise ( ISE ) with a conventional exercise ( CE ) on patients with ankylosing spondylitis ( AS ) stabilized by tumor necrosis factor ( TNF ) inhibitor therapy by comparing a combination group with a CE-alone group . Methods . Forty-six patients ( 44 men , 2 women ) were r and omized to the combination group ( ISE plus CE ; n = 23 ) or the CE group ( n = 23 ) . The CE regimen of both groups consisted of 20 exercises performed for 30 min once a day . The ISE was performed once a day for 30 min . The trial duration was 16 weeks . Patients were assessed before and at the end of treatment by measuring the Bath Ankylosing Spondylitis Disease Activity Index , Bath Ankylosing Spondylitis Functional Index ( BASFI ) , chest expansion , finger to floor distance , pulmonary function measures , and 6-min walk distance . Results . Both groups improved significantly in terms of chest expansion ( p < 0.01 ) , finger to floor distance ( p < 0.01 ) , and BASFI ( p < 0.05 ) after completing the exercise program . However , only the combination group showed significant improvements in the forced vital capacity ( p < 0.05 ) , total lung capacity ( p < 0.01 ) , and vital capacity ( p < 0.05 ) . Although this did not achieve statistical significance , the combination group was mildly superior to the CE-alone group in functional disability and pulmonary function measures . Conclusion . Combining ISE with a CE can provide positive results in patients whose AS has been clinical ly stabilized by TNF inhibitor therapy The objective of this study is to assess the effects of Global Postural Reeducation ( GPR ) in patients with ankylosing spondylitis and compare GPR with group conventional segmental self-stretching and breathing exercises . This is a controlled interventional study of 38 patients divided into 2 groups : a GPR group ( n = 22 ) and a control group ( n = 16 ) . Both groups were treated for more than 4 months . With the GPR group patients , positions that stretched the shortened muscle chains were used . With the control group patients , conventional segmental self-stretching and breathing exercises were performed . The variables analyzed were pain intensity , morning stiffness , spine mobility , chest expansion , functional capacity ( Health Assessment Question naire – Spondyloarthropathies – HAQ-S ) , quality of life ( Medical Outcome Study Short Form 36 Healthy Survey – SF-36 ) , and disease activity ( Bath Ankylosing Spondylitis Disease Activity Index – BASDAI ) . Statistical analysis was used with a significance level of P < 0.05 . There was a statistically significant improvement for all the parameters analyzed between pre- and post-treatment in both groups . In the intergroup comparison , the GPR group showed a significantly greater improvement in morning stiffness ( P = 0.013 ) , spine mobility parameters , except finger-floor distance ( P = 0.118 ) , in chest expansion ( P = 0.028 ) , and in the physical aspect component of the SF-36 ( P = 0.001 ) . The results of this study showed that individual treatment with GPR ( overall stretching ) seems to have better clinical outcomes than group treatment with conventional segmental self-stretching and breathing exercises for patients with ankylosing spondylitis The objective of this study was to investigate the effects of Pilates on pain , functional status , and quality of life in patients with ankylosing spondylitis . The study was performed as a r and omized , prospect i ve , controlled , and single-blind trial . Fifty-five participants ( 30 men , 25 women ) who were under a regular follow-up protocol in our Rheumatology Clinic with the diagnosis of AS according to

Moderate evidence supports exercise interventions in improving physical function , disease activity and chest expansion compared to controls ; there is low-level evidence of improved pain , stiffness , spinal mobility and cardiorespiratory function .
Supervised group exercise yields better outcomes than unsupervised home exercise .
The addition of aerobic components to flexibility programmes  improves cardiorespiratory outcomes , but not cardiovascular risk factors .
The most effective exercise protocol remains unclear .
Current evidence suggests that therapeutic exercises are beneficial for adults with ankylosing spondylitis ; effects on other SpA subtypes are unknown
