Magnetic Resonance Imaging (MRI)-Confirmed Soft Tissue Disorders as 'Model' for Anti-Inflammatory Effect of LLLT (785 nmu)

摘要

Thirty three patients (pts) with MRI- detectable soft tissue disorders (STD), mainly of feet (23 pts) and shoulders (7 pts), were included in this pilot study. LLLT was conducted by infrared diode GaAlAs (wavelength 785 nmu). We used a combination of point (75 mW) and area (14 diodes x 10 mW) applicators. Results were assessed using a visual analog scale (VAS) as well as patient's assessment score (in all cases) and MRI (in 13 pts).Baseline MRI demonstrated soft tissue inflammation in various localisations. Between 45 to 60% of patients improved at least 50% immediately and/or 1 month after initiation of LLLT and response was maintained until the 6-months evaluation. Remission was observed in 36 and 30% of the patients after one and six months, respectively. In accordance with the clinical data, MRI showed the disappearance (in eight patients) or a substantial regression of the MRI- findings (in two patients). A minority of patients (21 and 30% at one and 6 months) did not respond clinically or with regard to MRI-findings.
