Exercise programs in trials for patients with ankylosing spondylitis: do they really have the potential for...

Area of Science:

• Rheumatology
• Exercise Science
• Clinical Trials

Background:

• Ankylosing spondylitis (AS) is a chronic inflammatory disease affecting the spine.
• Exercise is a key component in managing AS, but trial quality varies.
• Evaluating exercise program effectiveness requires standardized methodologies.

Purpose of the Study:

• To assess the potential effectiveness of exercise programs in randomized trials for AS patients.
• To identify areas for improvement in the design and reporting of exercise interventions for AS.

Main Methods:

• Systematic literature search of randomized trials for AS exercise programs.
• Analysis based on American College of Sports Medicine (ACSM) recommendations for fitness components.
• Evaluation of physiologic response measurement and adherence monitoring.

Main Results:

• Twelve trials (826 patients) were analyzed; cardiorespiratory, strength, and flexibility components were examined.
• Only one trial met ACSM recommendations for cardiorespiratory exercise, showing the largest aerobic capacity improvement (ES 2.19).
• Muscular strength training was poorly implemented; flexibility training was often poorly described, though spinal mobility improved (ES 0.02-0.67). Adherence was rarely adequately reported.

Conclusions:

• Exercise interventions in AS trials can be enhanced in quality.
• Future research should prioritize standardized measurement and reporting of physiologic responses and adherence.
• Improved trial design will lead to more reliable evidence on exercise effectiveness for AS.
