探讨点式直线偏振光穴位照射对腰椎间盘突出症状缓解的疗效观察。选取腰椎间盘突出症患者44例，随机分为观察组（A）与对照组（B）两组。A组行点式直线偏振光照射穴位治疗22例，B组传统针刺穴位治疗22例。在治疗前后2周、4周分别采用视觉模拟评分法VAS,腰痛评分表JOA进行疗效分析。结果表明：1）点式直线偏振光（A组）与传统针刺穴位（B组）两组治疗后VAS值和JOA值与治疗前比较有显著提高（P<0.05），说明两组治疗方法治疗腰椎间盘突出症效果明显；2）治疗后，两组之间对比，点式直线偏振光穴位照射与传统针刺疗效（P>0.05）无统计学差异。JOA治疗后总改善率评分为观察组89%，对照组86%。点式直线偏振光穴位照射对腰椎间盘突出患者缓解腰腿痛改善生活功能障碍有明显效果，其疗效与传统针刺效果相当，但弥补了传统针刺治疗的不足，扩大了适应症范围。

Observation on the effect of pointtype linear polarized light point irradiation on the relief of lumbar disc herniation. Fortyfour patients with lumbar disc herniation were randomly divided into two groups: observation group(A)and control group(B): group A(22 cases) was treated with pointpoint linear polarized light irradiation and group B(22 cases)was treated with traditional acupuncture. Two weeks and four weeks before and after treatment, the curative effect was analyzed by visual analogue score(VAS)and low back pain scale Japanese orthopaedic association scores(JOA). 1)After treatment, the VAS and JOA value of point type linear polarized light(group A)and traditional acupuncture point(group B)were significantly higher than those before treatment(P<0.05). The results showed that the treatment of lumbar disc herniation in the two groups was effective. 2)After the treatment, there was a comparison between the two groups. There was no statistical difference between point type linear polarized light point irradiation and traditional acupuncture(P>0.05). The total improvement rate after JOA treatment was 89 in the observation group and 86 in the control group. Pointtype linear polarized light point irradiation has an  obvious effect on relieving lumbago and leg pain in patients with lumbar intervertebral disc herniation, and its curative effect is similar to that of traditional acupuncture, and it makes up for the deficiency of traditional acupuncture treatment and expands the scope of indication.
