Table 4.

Levels of lipid peroxidation parameters, total oxidative status (TOS), and oxidative stress (OSI) index (mean value ± standard deviation SD) in AS patients before and after the completion of a cycle of ten whole-body cryotherapy procedures with subsequent kinesiotherapy (WBC group) or a cycle of ten kinesiotherapy procedures only (KT group), with statistical analyses. (p): plasma; (s): serum; (e): erythrocyte lysates; Δ: difference prior to post treatment.
