Abstract：
UNASSIGNED: Spasticity is a common symptom of multiple sclerosis (MS) which affects mobility. Dry Needling (DN) has shown a reduction in spasticity in neuromuscular conditions such as stroke and spinal cord injury although the mechanism of action is still unclear. In spastic individuals, the Rate-Dependent Depression (RDD) of the H reflex is decreased as compared to controls and analyzing the effects of DN in the RDD may help to understand its mechanism of action.
UNASSIGNED: To evaluate the effect of Dry Needling on spasticity measured by the Rate-dependent Depression (RDD) of the H reflex in an MS patient.
UNASSIGNED: Three time points were evaluated: Pre-intervention (T1), Post-intervention assessments were carried out in the seventh week at two-time points: Before DN (T2) and After DN (T3). Main outcomes included the RDD and latency of the H reflex in the lower limbs at stimulation frequencies of 0.1, 1, 2, and 5 Hz in a five consecutive pulses protocol.
UNASSIGNED: An impairment of the RDD of the H reflex at frequencies ≥1 Hz was found. Statistically significant differences were found when comparing the mean RDD of the H reflex in Pre-intervention compared to Post-intervention at 1, 2, and 5 Hz stimulation frequencies. Mean latencies were statistically lower when comparing Pre- vs Post-intervention.
UNASSIGNED: Results suggest a partial reduction in spasticity represented by decrease of the excitability of the neural elements involved in the RDD of the H reflex following DN. The RDD of the H reflex could be implemented as an objective tool to monitor changes in spasticity in larger DN trials.

摘要：
■痉挛是多发性硬化症（MS）的常见症状，会影响活动性。尽管作用机制尚不清楚，但干针（DN）已显示出在中风和脊髓损伤等神经肌肉疾病中痉挛的减少。在痉挛的个体中，与对照组相比，H反射的速率依赖性抑郁（RDD）降低，分析DN在RDD中的作用可能有助于了解其作用机制。
■评估干针对MS患者H反射的速率依赖性抑制（RDD）测量的痉挛状态的影响。
■评估了三个时间点：干预前（T1），干预后评估在第7周的两个时间点进行:DN前(T2)和DN后(T3)。主要结果包括在五个连续脉冲协议中，在0.1、1、2和5Hz的刺激频率下，下肢H反射的RDD和潜伏期。
■发现在频率≥1Hz时H反射的RDD受损。当在1、2和5Hz刺激频率下比较干预前与干预后相比的H反射的平均RDD时，发现统计学上的显着差异。比较干预前与干预后的平均潜伏期在统计学上较低。
■结果表明痉挛的部分减少，表现为DN后H反射的RDD中涉及的神经元的兴奋性降低。H反射的RDD可以作为客观工具来监测较大DN试验中痉挛的变化。
