The Influnce of Epidural Steroids Injections with Transforaminal and Interlaminal Approaches on Quality of Sleeping, Anxiety, and Depression in Patients With Chronic Lumbal Radicular Pain - Prospective, Randomized Research
Chronic lumbar radicular pain is connected with the anxiety, depression and sleep disorders. The aims of this study are to compare the effect of pain on sleep quality, anxiety and depression in patients receiving interlaminar and transforaminal epidural steroids injections. The study is an original scientific-research work, a prospective randomized controlled clinical trial that included 70 patients with lumbar radicular pain at the Clinical Hospital Centre Osijek. The selected patients were divided into two groups considering the approach of administration of epidural steroids, the interlaminar (IL) and transforaminal group (TF). The anxiety, depression and sleep disorders were evaluated with questionnaires "Hospital Anxiety and Depression Scale (HADS)" and "Questions for assessing sleep in chronic pain". In the end 64 patients completed the study, 41 women (64.1%) and 23 men (35.9%). Significantly lower values were recorded during the assessment of the sleep quality in the group with the interlaminar injection of steroids (ANOVA, p = 0.030), compared to the group with the transforaminal injection of steroids (ANOVA, p = 0.002), but there is no difference between the groups. In both groups, there is an improvement in anxiety and depression, but only in the sixth measurement a significantly lower evaluation value of the HADS questionnaire was obtained in transforaminal (TF) group (Mann Whitney test, p = 0.025). Within the TF group, the values of anxiety (Friedman's test, p <0.001) and depression (Friedman's test, p = 0.007) are significantly reduced. In patients who received epidural steroids injection with a transforaminal approach, lower levels of depression and anxiety were observed as there was a greater reduction in pain, compared to an interlaminar group. Sleep quality was higher in patients who received steroids via transforaminal compared to the interlaminar approach.
