背架對下背痛患者背肌肌電活動之影響：初步研究
The effects of spinal Braces to the paraspinal myoeletric activity of backache patients-preliminary study
摘要
穿著背架是治療下背痛常用的方法之一．其治療原理可能為減少腰椎活動．分擔脊柱壓力．放鬆軀幹肌肉等，本研究就是為探討背架之穿著對下背痛患者背肌肌電活動之影饗。總共搜集十名男性．其中六名為背病患者．四名為正常人。以表面肌電圖儀量測背部肌肉的活動情形。 觀察靜態姿勢如靜坐、站立、彎腰、及動態實驗下穿著軟背架和硬背架及未穿背架時之相對肌電活動值。結果發現雖然有不少測試值顯示背架的穿著在各種姿勢或活動時會使肌電活動降低．但同時亦在背痛者穿著背架後之測試值中．約有六分之一以上比未著背架時高出兩倍以上．而正常人中穿著背架後之測試值中只有三十分之一比未著背架時高兩倍以上。顯示背痛病患者穿著背架可能會造成背肌活動增加。若欲處方背架以治療背痛時．須考慮肌肉活動可能改裝．以免因不當使用．反而使病情加劇。

Lumbar spinal bracing is one of the methods used for management of low back pain. The effect of spinal brace to the paraspinal myoelectric activity is not well investigated. Most of the papers published concerned about the myoelectric activity of normal subject wearing spinal brace. We carry out this study to evaluate the effect of lumbar spinal brace on the paraspinal muscle activity of low back pain patient. Totally 10 mates were collected to proceed the program. Six of them were backache patinets, and the other 4 were normal subjects without history of low back pain .There is no significant difference in their age, height and body weight .We use surface electromyography to study the muscular activity of paraspinal muscles. In many situation, the myoelectric activity would be decreased on brace wearing. There is still about one sixth of the data collected from backache patients showing twice higher myoelectric activities on brace wearing. And only about one thirtieth of the data collected from normal subjects reveal twice higher myoelectric activity on brace wearing. Spinal brace may have the effect of truck support, still it could increase paraspinal muscular activities of backache patients on various situations . We should take this into consideration when prescribing spinal braces for backache patients to prevent further aggravation of back pain.
