The purpose of the study was to assess the length of TLF and to evaluate the strength of muscles attached to it in subjects with and without nonspecific low back pain (NSLBP).
31 patients with NSLBP and 31 healthy individuals were included in the study. In each subject the TLF length was assessed by quantifying lumbar rotation using Back range of motion (BROM-II) instrument. The endurance of transverses abdominis was assessed using the pressure biofeedback unit while the strength of Latissimus dorsi, internal and external oblique's were assessed using MMT. Outcome measure such as Range of Motion (ROM) was compared across the group using independent sample T-test. While the muscle strength of Latissimus dorsi and oblique's were compared across the group using Man-whitney U- test. Transverse abdominis endurance was tested using chi-square test.
There was statistically significant difference in the length of TLF of subjects with NSLBP when compared with subjects without NSLBP. When the strength of Latissimus dorsi muscle, transverses abdominis muscle and internal and external oblique's muscle was assessed no significant (p value > 0.05) difference was found in either group.
There was statistically significant reduction in length of TLF but there was no difference in the strength of Latissimus dorsi, internal and external oblique's or endurance of transverses abdominus attached to the TLF in individuals with NSLBP and without low back pain. This study will help in determining the inclusion of TLF and the associated structures in evaluation and management of subjects with NSLBP.
本研究旨在评估有和无非特异性下腰痛(NSLBP)受试者的 TL 长度,并评估附着在其上的肌肉强度。
本研究纳入 31 例 NSLBP 患者和 31 例健康受试者。在每个受试者中,通过使用背部活动范围(BROM-II)仪器量化腰椎旋转来评估 TL 长度。使用压力生物反馈单元评估腹横肌的耐力,而使用 MMT 评估 Latissimus dorsi、内斜肌和外斜肌的强度。使用独立样本 t 检验比较组间的运动范围(ROM)等结果测量值。使用曼-惠特尼 U 检验比较组间 Latissimus dorsi 和斜肌的肌肉力量。使用卡方检验测试腹横肌耐力。
与无 NSLBP 的受试者相比,有 NSLBP 的受试者的 TL 长度存在统计学显著差异。当评估 Latissimus dorsi 肌肉、腹横肌肌肉和内斜肌和外斜肌的强度时,两组之间均未发现显著差异(p 值>0.05)。
TL 长度存在统计学显著降低,但在 NSLBP 和无腰痛受试者中,Latissimus dorsi、内斜肌和外斜肌或附着在 TL 上的腹横肌的强度和耐力没有差异。本研究将有助于确定 TL 和相关结构在评估和管理 NSLBP 受试者中的纳入。
