这项可行性研究使用了新的加速计(振动)和麦克风(声音)方法来评估侧位脊柱手法(SMT)前后起源于腰椎的克隆症。本研究包括5名健康受试者和5名腰痛(LBP)受试者。9个加速计和1个专门的定向麦克风被应用于腰部，从而能够评估克隆体。每个受试者都接受了全腰椎活动范围(ROM)、双侧腰椎SMT和重复的全腰椎活动范围(ROM)。在完整的ROMS之后，受试者接受由有执照的脊椎医生进行的两侧侧卧位腰椎SMT。所有SMT前后的加速度计和麦克风都进行了录音。主要结果是一份关于克汀病患病率的描述性报告(每名受试者克汀病事件的平均数量)。受试者还被分成3个年龄组(18-25岁、26-45岁和46-65岁)进行比较。总体而言，SMT治疗后克汀病患病率下降(平均治疗前=1.4克隆症/受试者vs.治疗后=0.9)。从最年轻的年龄组到最大的年龄组，患病率逐渐增加(SMT前分别为0.0、1.67和2.0；SMT后分别为0.5、0.83和1.5)。LBP受试者的患病率高于健康受试者(SMT前LBP=2.0，SMT前健康=0.8；SMT后LBP=1.0，SMT后健康=0.8)，即使健康受试者比LBP受试者年龄更大(40.8岁对27.8岁)；占年龄的比例：SMT前LBP=2.0，SMT前健康=0.0；SMT后LBP=1.0，SMT后健康=0.3。我们的发现表明，进行更大规模的研究是可行的。其他发现还包括克龙病患病率随着年龄的增长而增加，LBP患者高于健康受试者，SMT后总体上有所下降。这项研究表明，使用加速计评估克氏定植有可能成为评估运动中脊柱关节(小关节/Z关节)功能以及LBP治疗(如SMT)对Z关节功能影响的结果测量/生物标记物。
This feasibility study used novel accelerometry (vibration) and microphone (sound) methods to assess crepitus originating from the lumbar spine before and after side-posture spinal manipulation (SMT). This study included 5 healthy and 5 low back pain (LBP) subjects. Nine accelerometers and 1 specialized directional microphone were applied to the lumbar region, allowing assessment of crepitus. Each subject underwent full lumbar ranges of motion (ROM), bilateral lumbar SMT, and repeated full ROM. Following full ROMs the subjects received side-posture lumbar SMT on both sides by a licensed doctor of chiropractic. Accelerometer and microphone recordings were made during all pre- and post-SMT ROMs. Primary outcome was a descriptive report of crepitus prevalence (average number of crepitus events/subject). Subjects were also divided into 3 age groups for comparisons (18–25, 26–45, and 46–65 years). Overall, crepitus prevalence decreased pre-post SMT (average pre= 1.4 crepitus/subject vs. post= 0.9). Prevalence progressively increased from the youngest to oldest age groups (pre-SMT= 0.0, 1.67, and 2.0, respectively; and post-SMT= 0.5, 0.83, and 1.5). Prevalence was higher in LBP subjects compared to healthy (pre-SMT-LBP= 2.0, vs. pre-SMT-healthy= 0.8; post-SMT-LBP= 1.0 vs. post-SMT-healthy= 0.8), even though healthy subjects were older than LBP subjects (40.8 years vs. 27.8 years); accounting for age: pre-SMT-LBP= 2.0 vs. pre-SMT-healthy= 0.0; post-SMT-LBP= 1.0 vs. post-SMT-healthy= 0.3. Our findings showed that a larger study is feasible. Other findings included that crepitus prevalence increased with age, was higher in LBP than healthy subjects, and overall decreased following SMT. This study showed that crepitus assessment using accelerometers has the potential of being an outcome measure/biomarker for assessing spinal joint (facet/Z joint) function during movement and the effects of LBP treatments (eg, SMT) on Z joint function.
