This pilot study presents data on the application of two different physiotherapy techniques and the comparison of their effectiveness in patients with radiologically confirmed intervertebral disc herniation. At baseline and the end of the application of the studied physiotherapy techniques, the subjects, after being distributed into two groups, underwent testing in order to determine their trunk stabilizer muscle strength, pain intensity at rest and on exertion, and the level of disability. The physiotherapy program consisted of individually selected exercises. Subjects of the first group additionally underwent sling exercise therapy, and subjects of the second group-physiotherapy with feedback exercises. Both combinations-physiotherapy with feedback exercises and physiotherapy with sling exercise therapy-statistically significantly reduced functional disability and lower back pain at rest and on exertion. The physiotherapy program with feedback exercises was more efficient than the physiotherapy program with sling exercise therapy when correcting imbalance in trunk stabilizer muscle strength. The impact of both physiotherapy programs on trunk stabilizer muscle strength was similar. Both combinations-physiotherapy with feedback exercises and physiotherapy with sling exercise therapy-had an equal impact on the decrease in pain and functional disability
