The effect of polarized polychromatic non-coherent light (Bioptron) therapy on patients with lower back pain

Mariyana Mihaylova, Zhenya Ruseva, Silviya Filkova


INTRODUCTION: Lately the polarized polychromatic non-coherent lower energy light emitted by the Bi­optron lamp has become more widely used in the physiotherapeutic practice.

AIM: To study the effect of polarized polychromatic incoherent low energy light on pain, motor activity and quality of life in patients with vertebrogenic lower back pain and to compare it with other methods used in practice.

MATERIALS AND METHODS: Object of the study were 60 patients with lower back pain. A control group (N=30, age 46±11.5 y.) was treated with basic therapy and the Bioptron apparatus. Functional tests of the motor activity (test of Thomayer and test of Schober), evaluation of the pain using visual analogue scale (VAS) evaluation of the quality of life using the Roland-Morris test in the beginning, at the end and 1 month after the treatment were used to evaluate the effectiveness of treatment.

RESULTS: The results have a statistical significance of (p<0.05) for both groups regarding the reduction of the pain syndrome, the functional tests for mobility in the lumbar region and the quality of life. There’s also a statistical significance in comparing the results of the test group (TG) and the control group (CG) (p<0.05).

CONCLUSION: Both methods reduced pain, improved the mobility of the lumbar region and improved the quality of life of patients with lower back pain. The complex methodology incorporating basic treatment with the use of polarized polychromatic non-coherent low energy light yielded better results than just ba­sic treatment.
