Yes. Dr Houssien carried out a study to analyse the effects of low-level laser acupuncture therapy in comparison to traditional acupuncture.
In this study, 40 patients were equally divided into two groups. Each participant received only one session. Pain intensity was assessed on 100 mm visual analogue scale (VAS). The ranges of motion were measured using goniometry.
Assessment of the patients was carried out before the treatment, immediately after, 4 weeks later, 12 weeks later and 24 weeks later.
Immediately after the completion of treatment, the mean VAS dropped from 78 to 66 mm in the acupuncture group (G1) but increased at the follow-up visits to 76 mm after 24 weeks. In contrast, VAS decreased from 80 to 60 mm in G2. After 6 months of a single session Abduction increased from 72º to 74º in G1, while increased in G2 from 72º to 116º. The external rotation increased from 18º to 26º in G1 compared to an increase from 18º to 46º in G2. There were also increases in internal rotation from 40º to 54º in G1, but it increased from 38º to 57º in G2.
