Abstract

<p>【目的】非特異的腰痛(以下,NLBP)では深部筋機能不全やサイドブリッジ持久力テスト(以下,SBET)保持時間低下が報告されているが,その際の深部筋疲労についての報告はない。本研究の目的は,NLBP 者におけるSBET 実施時の体幹深部筋疲労を,T2 値を指標として明らかにすることである。【方法】対象は腰痛のない対照群とNLBP 群の2 群とした。測定項目はSBET 保持時間と,SBET 前後の深部筋T2 値とした。統計解析はSBET 前後と腰痛の有無を独立変数,深部筋T2 値を従属変数とした2 元配置分散分析および単純主効果の検定を実施した。【結果】SBET 保持時間はNLBP 群が有意に低値を示した。深部筋T2 値においてSBET 前後・腰痛経験の主効果および交互作用が示された。単純主効果の検定ではNLBP 群のPost でT2 値は有意に高値を示した。【結論】NLBP 者では体幹筋等尺性持久力低下とSBET における体幹深部筋易疲労性を認めた。</p>

<p><b>Purpose</b>: Nonspecific low back pain (NLBP) that cannot reliably be attributed to a specific disease or spinal abnormality has been reported in individuals who have disorder in local trunk muscles such as transversus abdominis. Though there are studies on side bridge endurance test (SBET) continuation time as an index that showed isometric endurance is shortened in individuals with NLBP, there are few reports on the fatigue of local trunk muscles. Incidentally, from T2 weighted image of magnetic resonance imaging, T2 values enable the fatigue of local trunk muscles to be evaluated. The purpose of this research is to clarify the fatigue of local trunk muscles in NLBP individuals during SBET from T2 value.</p><p><b>Methods</b>: The participants were divided into two groups, the control group without low back pain and the NLBP group. The measurement items were SBET continuation time and T2 value of local muscles at pre and post SBET. A two-way analysis of variance and simple main effect was conducted. The independent variable was the group and the dependent variable was T2 value of pre and post SBET continuation time.</p><p><b>Results</b>: SBET continuation time was low in the NLBP group. Relationship was shown in the T2 value of local trunk muscles. Simple main effect showed in pre and post SBET and T2 value of post SBET was high in the NLBP group.</p><p><b>Conclusion</b>: The findings of the investigation showed there was a decrease of isometric endurance in trunk muscles and a decline of local trunk muscle endurance at SBET in the NLBP group.</p>
