Effectiveness of Local Cryotherapy Treatment with the Use of Carbon Dioxide and Liquid Nitrogen Among Patients with Low Back Pain Syndrome
Notice bibliographique
Résumé
Introduction: Low back pain syndromes (LBPS) are common. One of the methods of treating LBPS is local cryotherapy, which can be based on various cooling substances. In the available literature, it is suggested that effective cold treatment may depend on the type and temperature of the cooling substance used. Research objective: The aim of the study was to evaluate the effectiveness of 2 local cryotherapy (Carbon Dioxide and Liquid Nitrogen) types among patients with low back pain syndrome (LBPS). Materials and methods: The study included 60 patients diagnosed with chronic LBPS of discopathic origin. Patients were randomised into 2 study groups. Local cryotherapy treatment with Carbon Dioxide was used in the 1st group (G1), while in the 2nd (G2), cryotherapy treatment with applied Liquid Nitrogen. Two measurements were taken, before and after 2 weeks treatment. The following were used for assessment: centralisation of symptoms (Pain Drawings), pain intensity (Numeral Rating Scale), duration of the current pain episode (Quebec Task Force Classification), level of disability (Roland-Morris Disability Questionnaire), quality and intensity of subjective pain (McGill Pain Questionnaire), patients’ emotional state (Adjectival Scale for Testing Emotions) and self-efficacy related to pain (Pain Self-Efficacy Questionnaire). Statistical analysis was performed via the Student’s t-test for dependent and independent samples. Results: In both study groups, the perceived pain was either completely eliminated or centralised to the spine, hip joint and buttock. The level of pain, disability and pain-related self-efficacy decreased significantly, regardless of the therapy used. In terms of these variables, no greater therapeutic efficacy was demonstrated with either cryostimulation treatment. Qualitative assessment of pain and emotions (especially anxiety and anger) decreased significantly in G1 and G2. However, in the nitrogen-treated group, a significantly greater improvement was noted for WOB:OC, anger and anxiety scores (for these variables, the G2 group started from a higher level prior to therapy). Conclusions: Both analysed treatments are equally effective in terms of variables such as: centralisation of symptoms, level of pain intensity, disability, joy, self-efficacy related to pain, as well as the majority of the analysed MPQ indicators. Cryostimulation with liquid nitrogen may be more effective, but only in improving the WOB: OC index of the MPQ questionnaire and the level of anger and anxiety. Nonetheless, the obtained results do not allow for definitive confirmation of these results. The use of both cryostimulation treatment methods may assist in the treatment process of LBPS.
