Effects of combining thoracic lymphatic pump technique and exercises on patients with chronic mechanical low back pain

Purpose. The study aimed to compare the effects of combining thoracic lymphatic pump technique (TLPT) and exercises versus exercises alone on pain intensity, lumbar spine mobility, and functional disability in patients with chronic mechanical low back pain (CMLBP), the second most common orthopedic condition. Methods. Fifty-two CMLBP patients, whose mean age was 25 years, were classified into 2 equal groups randomly. Group (A) received exercises (hamstring stretching, lower back stretching, abdominal strengthening, and trunk extensor strengthening). Group (B) received the same exercises plus the thoracic lymphatic pump technique. Both groups received 12 sessions on nonconsecutive days. All patients were evaluated using the Visual Analogue Scale (VAS) for pain intensity, the Modified-Modified Schober test (MMST) for lumbar mobility (flexion-extension), and the Oswestry Disability Index (ODI) for functional disability. Assessments were performed prior to and after the end of treatment. For data analysis, the unpaired t-test, chi-squared test, and mixed MANOVA test were used. Results. The study found significant improvements in pain intensity, lumbar mobility (flexion, extension), and functional disability in both groups (P < 0.05), with no significant difference in pain intensity or lumbar spine mobility. However, group (B) had a statistically significant advantage in functional disability (P < 0.05). Conclusion. The addition of the thoracic lymphatic pump technique to therapeutic exercises significantly enhances pain, lumbar spine mobility, and functional abilities in CMLBP patients than therapeutic exercises alone.
