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.
■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。
