摘要

瑜珈是相當普及且一般認為對身心有益的運動，但相關研究往往過於主觀。瑜珈與磁振照影的相關研究相當稀少，因此我們設計了瑜珈與腰椎間盤退化疾病的病例對照研究。
研究邀請18位瑜珈指導者及18位無臨床症狀健檢病例做對照。所有的腰椎間盤的退化程度以磁振照影分級並加以統計分析。
在實驗組的瑜珈經驗平均是12.9±7.5年；在第一二、第二三、第三四、第四五、第五腰第一薦、和腰部90個腰椎間盤的退化分級，在瑜珈指導者中位數依序為2(3,2),2(3,2),3(3,1),3(4,1),2(4,1)及2(4,1)，而在對照組為2(3,2),2.5(4,2),3(4,1),3(4,1),3(4,1)及3(4,1)；在瑜珈組90個腰椎間盤分級中位數明顯較低，特別是在第二三和第三四兩節。
瑜珈經驗超過十年可有效預防腰椎間盤退化疾病。

Yoga is a popular exercise with evidence of various physical and psychological benefits. However, most of these studies are based on subjective scales. To our knowledge, there are very few original studies on MRI analyses of yoga practicing individuals at present. Here we conducted a MRI-based case-control study of yoga and lumbar degenerative disc disease (DDD).
Eighteen yoga instructors were enrolled in our study and other 18 asymptomatic cases were randomly selected from our health check up database as control group. All lumbar discs of these cases were graded by using MRI and analyzed statistically.
The mean practice period is 12.9±7.5 in yoga group. The median grading of the L1/2, L2/3, L3/4, L4/5, L5/S1 and the 90 lumbar discs was 2 (3,2), 2 (3,2), 3 (3,1), 3 (4,1), 2 (4,1), 2 (4,1) in yoga group and 2 (3,2), 2.5 (4,2), 3 (4,1), 3 (4,1), 3 (4,1), 3 (4,1) in control group, respectively. The median grading of the 90 discs was significantly lower in the yoga group than in the control group. The median grading of the L2-3 and L3-4 discs was significantly lower in the yoga group than in the control group.
The grading of DDD was lower in the study group that had practiced yoga for more than 10 years as compared to the control group.
