慢性下背部扭傷患者腰椎活動度及活動速度之研究
Lumbar Flexibility of Patients with Chronic Low Back Strain/Sprain
摘要
下背部疼痛患者的腰椎活動度及活動速度眾說紛紜，尤其是活動度方面，有人認為下背部疼痛患者的活動度應該較健康者差，有人卻認為不見得較差，更有甚者，認為反而較健康者更大。回顧文獻，大部份研究的受試者其下背痛之原因包羅萬象，年齡也參差不齊。因此作者特別選擇年齡只局限在20-49歲之間的下背部扭傷患者作為研究對象，探討這類患者腰椎的活動度及活動速度，以為臨床診斷、治療的參考。全部47位受試者皆為下背部扭傷超過6個月以上之患者，疼痛指數不超過2，腰椎測試過程中不會引起明顯疼痛而影響測試結果者。另選擇年齡、身高、體重、性別相仿的76位無下背痛受試者做為對照組。到試過程如下：腰椎暖身運動後，穿上腰椎活動度則試儀(Lumbar Motion Monitor)，雙腳分開如肩寬，雙手交叉抱胸前，測前彎後仰，左右旋轉及左右側彎三個方向。每個方向都連續做8秒，以最大角度、最快速度完成；以8秒內所表現的最大角度值及最大速度值作為則量值。結果：下背部扭傷患者之腰椎活動度不一定比健康者大或小，但是腰椎活動速度卻一定比健康者慢。至於在文獻上常報告的一些與腰椎活動度具相關性的因素：例如性別、身高、體重，在下背部扭傷患者群中，這些因素與腰椎活動度並再統計上的相關性。本實驗之結果其活動度與活動速度可各別做為臨床治療與診斷的參考。

It is controversal that the range of motion in lumbar spine of low back pain patients is greater or less than that of healthy spine. Review literatures, we suppose one of the reasons maybe possible due to not classify the pathologic problem of low back pain clearly. So this experiment selected 47 cases with chronic low back strain/sprain within 20-49 years old for further study. All of 47 cases follow the following criteria: (1) The onset of low back strain/sprain must be lasting over six months. (2) The pain scale was less than 2. (3) The back pain never aggravates during the testing procedure. (4) Exclude the patients with sciatic pain or other spinal pathologic change. In addition to, select another 76 cases of healthy subjects as control group, matching their age, sex, body weight and body height with experimental group. All of them did warm-up spinal exercises before they started the lumbar motion test with Lumbar Motion Monitor. The three tested directions included sagittal, horizontal and frontal planes. The biggest values of spinal range of motion and motion velocity were as the measurement values. The conclusions of this study were: (1) The velocity of trunk motion may be used as a valuable monitor of low back strain/sprain. (2) Some patients had less range and some patients had greater range of motion of lumbar spine than that of healthy subjects. (3) There was no correlation between the spinal motion of low back strain/sprain patients and the variables of their sex, body height and body weight.
