Dynamics of Changes in Isometric Strength and Muscle Imbalance in the Treatment of Women with Low back Pain

الملخص EN

The aim of the study was to evaluate the dynamics of isometric changes in strength and muscular lumbar-pelvic imbalances in the treatment of women with low back pain.

Forty-one women, nineteen in the study group (A) and twenty-two in the control group (B), participated in the study.

Magnetic resonance imaging (MRI) was performed to assess the degree of degenerative changes in the lumbar spine.

The diagnosis of isometric muscle strength and their imbalances was performed with the Tergumed 700 device.

After six weeks of therapy in the study group (A), there was a significant improvement in the strength of all the examined muscle groups.

However, in the control group (B), significant improvement occurred only in the strength of the lumbar flexor muscles and the flexor muscles on the left side.

Furthermore, there was a significant intensification of the imbalance of left flexor muscle strength compared to right flexor strength in group B.

Significant differences in favour of the study group (A) concerned the strength of the rotator muscles to the left, the strength of the extensor muscles of the lumbar spine, the strength of the flexors of the lumbar spine to the right, and the balance of the strength of the lumbar spine flexors to the left compared to the strength of the flexor muscles to the right.

Therapy with the Tergumed 700 system leads to an increase in the muscle strength of the lumbar and pelvic complex, compensating for its imbalance, bringing beneficial effects in the treatment of low back pain.
