Ankylosing spondylitis: integrated clinical and physiological perspectives.

Area of Science:

• Rheumatology
• Physiology
• Epidemiology

Background:

• Ankylosing spondylitis (AS) is a chronic inflammatory disease primarily affecting the spine.
• The role of axial skeletal muscle tone in AS pathogenesis remains unclear.
• Muscles and articular cartilage share common embryological origins, suggesting coordinated functions.

Purpose of the Study:

• To explore the hypothesis that axial muscle hypertonicity contributes to enthesopathic lesions in AS.
• To review clinical, epidemiological, and physiological evidence supporting a link between axial muscle tone and AS.
• To propose novel concepts regarding the intrinsic axial muscular system's role in AS.

Main Methods:

• Review of clinical and epidemiological data related to AS.
• Analysis of physiological principles of skeletal muscle tonus.
• Integration of embryological perspectives on muscle and cartilage development.

Main Results:

• Clinical and physiological observations suggest a potential relationship between axial muscular hypertonicity and AS.
• The axial kinematic chain, crucial for posture and mobility, may be implicated.
• A definitive link between axial muscle dysfunction and joint pathology in AS has not yet been established.

Conclusions:

• Axial muscle hypertonicity is proposed as a potential contributing factor to enthesopathic lesions in ankylosing spondylitis.
• Further investigation is warranted to elucidate the precise mechanisms linking axial muscle dysfunction to AS.
• This hypothesis opens new avenues for understanding and potentially managing AS.
