The purpose of this research was to determine the extent of reflex responses after spinal manipulative therapy (SMT) of the cervical and upper thoracic spine.
Eleven asymptomatic participants received 6 commonly used SMTs to the cervical and upper thoracic spine. Bipolar surface electromyography electrodes were used to measure reflex responses of 16 neck, back, and proximal limb muscles bilaterally. The percentage of occurrence and the extent of reflex responses of these muscles were determined.
Reflex responses after cervical SMT were typically present in all neck and most back muscles, whereas responses in the outlets to the arm and leg were less frequent. This trend was similar, although decreased in magnitude, after thoracic SMT.
Reflex responses were greatest after upper cervical SMT and lowest with thoracic SMT.
本研究的目的是确定颈椎和上胸椎脊柱手法治疗（SMT）后反射反应的程度。
11名无症状参与者接受了针对颈椎和上胸椎的6种常用SMT。使用双极表面肌电图电极双侧测量16块颈部、背部和近端肢体肌肉的反射反应。确定这些肌肉反射反应的发生率和程度。
颈椎SMT后的反射反应通常出现在所有颈部和大多数背部肌肉中，而手臂和腿部神经出口处的反应较少见。胸椎SMT后，这种趋势相似，尽管幅度有所降低。
上颈椎SMT后的反射反应最大，胸椎SMT后的反射反应最小。
