Background. Lower back pain is one of the most common problems in the human body relat-ed to the disturbances of the motor organ’s structure and function. It challenges contemporary physiotherapy which aim is to reduce or, when possible, eliminate pain, restore fitness for eve-ryday life and prevent recurrences. The aim of the study was to compare two physiotherapy programmes in terms of lowering pain intensity, improvement of lumbar and thoracolumbar spine mobility, as well as functional ability in females with lumbar spine discopathy. Material and methods. The study included 100 women aged 45-50 with lumbar spine disco-pathy being treated in outpatient conditions. The patients were divided into two 50-subject groups depending on the programme used. The physiotherapy programme for group I patients included classic massage, kinesiotherapy and interferential currents, and in group II: classic massage, kinesiotherapy and ultrasound. The research tool was the Numeric Pain Rating Scale (NRS), the Roland Morris Disability Questionnaire (RMDQ) and measurements of lumbar and thoracolumbar spine mobility. The Wilcoxon and Mann-Whitney U tests were used for the analysis. Results. After completion of the physiotherapy programme, the women in group I experi-enced significantly lower pain (p=0.037) and higher functional efficiency (p=0,001). The range of improvement, assessed by the difference in the results of study II and III, was signif-icantly higher for the II group of women (p=0,002). One month after completion of therapeu-tic treatment, there were no statistically significant differences between the groups (p=0,169, p=0,067). Conclusions. The use of interferential currents in the physiotherapy of individuals with lum-bar spine discopathy compared to ultrasound therapy allows for greater improvement in reduc-ing pain intensity, lumbar and thoracolumbar spine mobility, as well as higher functional effi-ciency. The effectiveness of ultrasound had increased over time since the end of therapy and only after one month in the case of both physiotherapy programmes, similar effects could be observed.
