Does a 3-month behaviour change intervention targeting physical activity (PA) increase habitual physical activity in adults with ankylosing spondylitis (AS)? Does the intervention improve health-related physical fitness, AS-related features, and attitude to exercise? Are any gains maintained over a 3-month follow-up? Parallel-group, randomised, controlled trial with concealed allocation, assessor blinding and intention-to-treat analysis. Forty adults with a diagnosis of AS, on stable medication, and without PA-limiting comorbidities. Over a 3-month period, the experimental group engaged in individually-tailored, semi-structured consultations aiming to motivate and support individuals in participating in PA. The control group continued with usual care. The primary outcome was PA measured by accelerometry over 1 week. Secondary outcomes included clinical questionnaires and measures of health-related physical fitness. Measures were taken at baseline, post-intervention, and after a 3-month follow-up period. Baseline characteristics were similar across groups, except age and body composition. There were statistically significant, moderate-to-large time-by-group effects in health-enhancing PA (mixed-design ANOVA for overall effect F(2, 76)=14.826, p<0.001), spinal mobility (F(2, 76)=5.691, p<0.005) and quality of life (χ2(2)=8.400, p<0.015) favouring the intervention group; post-intervention improvements were sustained 3 months later. No significant effects were seen in other physical fitness outcomes or on clinical questionnaires. No adverse effects were reported during the study. Health-enhancing PA, spinal mobility and quality of life were significantly improved after the intervention, and improvements were maintained at 3-month follow-up. NCT02374502.

Background: Exercise is a key component of the management of ankylosing spondylitis (AS). Despite numerous benefits, compliance with exercise programs is low. Little attention has been accorded to the experiences of individuals with AS toward physical activity (PA). This study aimed to explore the attitudes toward PA and exercise of adults with AS.Methods: A qualitative descriptive design using thematic analysis was used. Seventeen adults with AS participated in individual, semistructured interviews. Interviews were recorded, transcribed, coded and analyzed for themes and subthemes.Results: Four themes emerged from the analysis: (1) benefits, (2) barriers, (3) motivation, and (4) strategies and enablers. Benefits included amelioration of symptoms, improvements in general health, and enhancement of quality of life. Subthemes of barriers to PA included lack of resources, negative attitudes to exercise, misinformation, and condition-related factors. Motivation to exercise was influenced by intrinsic and extrinsic factors. Participants proposed strategies to enhance PA participation and exercise engagement.Conclusions: Awareness of the benefits of PA appears insufficient to motivate individuals with AS to exercise; a number of factors influence individual motivation to exercise. Many perceived barriers to PA may be considered modifiable. Individually-tailored interventions, collaboratively developed by the individual and the healthcare professionals, were proposed as strategies for effective PA and exercise prescription.

Objectives. This study examines the awareness and self-report knowledge of physical activity (PA) guidelines among adults with rheumatic conditions and evaluates rates of adherence to PA recommendations. Secondary aims include (i) investigating perceived benefits and barriers to exercise and (ii) exploring correlates associated with PA. Methods. This cross-sectional study involved adults attending an outpatient rheumatology clinic completing a questionnaire. Closed- and open-ended questions enquired about awareness and knowledge of PA guidelines, and a single-item self-report measure of PA was included. Perceptions of exercise were assessed using the Exercise Benefits and Barriers Scale. Descriptive statistics described participant characteristics and age-adjusted bivariate analyses explored associations between socio-demographic and condition-related factors and PA. Results. A total of 401 adults (134 males, 267 females) completed the questionnaire. Only 17.6% of respondents were aware of national PA guidelines and 17.4% accurately identified the frequency and duration of the recommendations. A quarter of respondents (26.7%) reported adherence to the guidelines, while 30.5% reported no weekly PA. Higher perceived benefits and lower perceived barriers to exercise were positively associated with PA behaviour. Conclusion. A large majority of respondents were not aware of PA guidelines and self-report knowledge of PA recommendations was largely inaccurate. Despite the role of PA in health promotion and in the management of rheumatic conditions, adherence to PA recommendations was low. Level of education, perceived benefits and barriers to exercise, and awareness and self-report knowledge of PA guidelines are associated with PA behaviour.
