Abstract:
In the previous paper, we reported a clinical study on laser irradiation stimulation for pain diseases. In the present study, we examined the effect of laser irradiation stimulation on peripheral blood circulation and its clinical effectiveness in the treatment of shoulder stiffness.
[METHOP] Five healthy adults were irradiated with low energy semiconductor laser (Ga-Al-As, 70mw, 830nm) at the Jianjing (VF21) for ten minutes. Skin blood flow near the stimulated point was measured using Laser-Doppler method before and after (for 20min.) irradiation.
Clinical effectiveness was examined for 50 patients with clonic shoulder stiffness who visited Anesthesiological Department of Osaka Medical College Hospital. The patients were randomly devided into two groups: laser irradiation group (L group) and Non-irradiation group (C group). To the C group, the apparatus was set but no laser was irradiated. Stimulation points were Tianzhu (VU10), Jianjing (VF21), Jianwaishu (IT14) and other points commonly used for shoulder stiffness. According to the numerical scale of subjective symptom reported by the patients immediately after the stimulation, therapeutic effictiveness was rated into four grades: “marked improvement” “improvement” “slightJimprovement” and “no change”. “Marked improvement” and “improvement” were regarded as effective cases.
[RESULTS] After laser stimulation, blood flow increased several times heigher than the original level but it tended to decrease back to the original level within the measuring period. The incedence of effective cases was 58% for L group and 40% for C group.
[CONCLUSION] Laser irradiation stimulation has been reported to have same effect as acupuncture, and gathering attention as stimulation method with less adverse effects. Our study demonstrated that laser stimulation induced transient improvement of local blood circulation.
