About

This study aimed to examine whether aerobic exercises, in addition to home exercises, have anti-inflammatory effects, which are evaluated by disease activity, acute phase reactants, and cytokine levels in axial spondyloarthropathy

Full description

Spondyloarthropathies (SpAs) are a group of chronic, inflammatory, and multisystemic diseases with common genetic, epidemiological, and clinical features. These diseases primarily involve the axial skeleton.

The pathogenesis of SpA is multiple factors. The disease-specific inflammatory response, with the contribution of environmental factors based on genetic predisposition, is responsible for the pathogenesis of the disease.1 The main cytokines thought to be involved in the pathogenesis of axSpa are tumor necrosis factor-alpha (TNF-α), interleukin-17 (IL-17), IL-23, IL-22, IL-6, IL-7, interferon-gamma (IFN-γ), IL-12, and IL-26.

There is no definitive marker associated with disease activity. Studies on cytokine levels and disease activity have shown that TNF-α, IL-6, IL-17, IL-23, and IFN-γ levels may be associated with disease activity in AS patients.4-9 Nonpharmacological and pharmacological methods are used together for the treatment of SpA. Non-pharmacological methods include patient education, smoking cessation, regular exercise, and physiotherapy practices.

Aims of exercise therapy are to improve or preserve range of motion, flexibility, balance and to improve muscle strength and aerobic capacity. Posture, stretching, breathing, strengthening, and aerobic exercises are the most recommended in treating AS.

Exercise therapy is described as the cornerstone treatment of axSpA by the European Alliance of Associations for Rheumatology (EULAR). Although patient compliance with exercise therapy is not easy, the advantages of exercise are that it is cheap, low-risk, and easy to apply compared to pharmacological treatments.

The anti-inflammatory effects of exercise have recently been discussed. Few studies have investigated the anti-inflammatory effects of exercise in patients with AS. While some of these studies showed significant improvement in disease activity, functional status, flexibility, and CRP with aerobic exercise in patients with AS, some did not. Although a few studies have shown a significant decrease in TNF-α levels in AS patients with non-aerobic exercise programs, no study has examined the changes in TNF-α and IL-17 levels with aerobic exercise treatment.

The primary aim of our study was to examine whether aerobic exercise, in addition to the home exercise program, has an anti-inflammatory effect in patients with axSpA, as evaluated by disease activity, acute phase reactants, and cytokine levels. Our secondary aim was to determine whether aerobic exercise, in addition to home exercise, has a positive effect on functional status, functional exercise capacity, quality of life, NSAID consumption, chest expansion, and spinal mobility.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: None (Open label)

---

54 participants in 2 patient groups

Home Exercise Group

Active Comparator group

Description:

The home exercise group performed only standard conventional exercises for 12 weeks, 3 days a week, once a day for 30 min, including cervical, thoracic, and lumbar spine flexibility, shoulder muscles, hip flexors, hamstring and quadriceps muscle stretching, spinal flexor stretching, and extensor strengthening and breathing exercises program was shown by the same physician. Patient compliance with the exercise program was monitored weekly using telemedicine.

Treatment:

Other: Home Exercise

Aerobic Exercise Group

Experimental group

Description:

The aerobic exercise group performed the following training: warm-up for 5 min, walking for 20 min at an intensity that would use 60-70% of the HR reserve, and cool down for 5 min. Additionally, they performed standard conventional exercises at home for 12 weeks, 3 days a week, once a day for 30 min, including cervical, thoracic, and lumbar spine flexibility, shoulder muscles, hip flexors, hamstring and quadriceps muscle stretching, spinal flexor stretching, and extensor strengthening and breathing exercises program was shown by the same physician. The aerobic exercise group performed on a treadmill under the supervision of a physician.
