Effect of whole body cryotherapy on low back pain and release of endorphins and stress hormones in patients with lumbar spine osteoarthritis.

Abstract

Introduction:

Low back pain (LBP) is the most common ailment in patients with lumbar spine osteoarthritis (OA). There are many methods to treat LBP, such as manual therapy, osteopathy, massage, physical exercise, and physical therapy. The most effective of these are manual therapy and exercises combined with physical procedures, such as whole body cryotherapy (WBCT). Whole body cryotherapy can induce various hormonal adaptations in patients with OA. This is probably the body's reaction to cold and stress. The purpose of the study was to evaluate the impact of WBCT on β-endorphins, cortisol and adrenaline release, as well as on LBP in patients with OA of the lumbar spine.

Material and methods:

The study group consisted of 30 patients with lumbar spine OA who underwent a series of WBCT combined with therapeutic exercises. Before and after the therapy each patient was examined using a visual analogue scale (VAS) and blood samples were collected for laboratory determinations (ELISA).

Results:

After WBCT, the decrease in LBP measured by VAS was statistically significant (p < 0.0001). The mean value of blood β-endorphin level increased after the therapy but the difference was statistically insignificant (p = 0.10). The mean value of the plasma level of cortisol after treatment increased and the difference was statistically significant (p = 0.0009). The plasma level of adrenalin after treatment increased slightly, but the difference was statistically insignificant (p = 0.08).

Conclusions:

Whole body cryotherapy combined with therapeutic exercises had a positive effect on LBP reduction in patients with OA. On the basis of these changes, processes that take place in the nervous and endocrine systems are a response to the stimuli of cold and stress. The mechanism of action of extremely low temperatures on the human body is still not fully understood.
