To use ultrasound (US) imaging to determine the validity and reliability of needle placement of two dry needling (DN) protocols for the lumbar multifidus (LM) in individuals with a high body mass index (BMI).
Twenty-one participants with a BMI higher than 25 kg/m completed the study. A US scanner was used to determine the location of needle placement after a 100 mm long needle was inserted in the LM at L4 and L5 following two DN protocols for the deep LM muscle. US images were saved and viewed 6 months later to determine the intra-tester reliability.
The probability of reaching the deep LM muscle was high (85-95%) at L4 and L5. Although the needle reached a bony landmark 85-100% of the time, it only reached the vertebra lamina as intended 70-75% of the time. The intra-tester reliability of needle placements based on analysis of real-time and recorded US images was poor-to-moderate.
Although the bony drop may not indicate that the needle has reached the vertebra lamina as the protocol intended, reaching a bony drop is still meaningful as it coincided with reaching the LM in the majority of participants.
使用超声（US）成像来确定两种用于高体重指数（BMI）个体的腰椎多裂肌（LM）的干针（DN）方案的针置放的有效性和可靠性。
21 名 BMI 高于 25kg/m 的参与者完成了这项研究。在 L4 和 L5 处插入 100mm 长的针后，根据两种用于深部 LM 肌肉的 DN 方案，使用 US 扫描仪确定针在 LM 中的位置。保存 US 图像，并在 6 个月后查看以确定内部测试者的可靠性。
在 L4 和 L5 处，针到达深部 LM 肌肉的概率很高（85-95%）。尽管针 85-100%的时间到达骨标志，但只有 70-75%的时间按预期到达椎板。基于实时和记录的 US 图像分析的针置放的内部测试者可靠性为差到中等。
虽然骨下降并不一定表示针已到达协议预期的椎板，但到达骨下降仍然具有意义，因为它与大多数参与者的 LM 到达相一致。
