Randomized, single blind, same subject crossover trial.
To compare the effects of two neurodynamic treatment doses on range of hip flexion (ROM HF) and electromyographic (EMG) activity of semitendinosus, at first onset of pain (P1).
A total of 26 healthy participants without low back or leg pain received each treatment in a random order with at least 48 hours between sessions. Baseline ROM HF and EMG magnitude of semitendinosus at P1 were collected. Subjects then received either 361 or 362 minutes of oscillating end of range (grade IVz) straight leg raise (SLR) neurodynamic treatment and were re-assessed for baseline measures.
There was no significant difference between groups in EMG magnitude (P50.190) and ROM HF (P50.739) at P1. There was also no significant difference within groups in EMG magnitude at P1 (P50.182); however, there was a significant improvement in ROM HF at P1 in both groups compared to baseline readings (P50.000), with increases of 6.7u and 5.1u for the 361- and 362-minute groups, respectively.
Findings indicate that 362 minutes of oscillating grade IVz SLR neurodynamic treatment has no additional benefit over 361 minute, on ROM HF or EMG magnitude of semitendinosus at P1. Using an oscillating SLR treatment may, however, help to increase pain-free ROM HF, although further studies are necessary to confirm this.
随机、单盲、同受试者交叉试验。
比较两种神经动力学治疗剂量在疼痛首次发作（P1）时对髋关节屈曲范围（ROM HF）和半腱肌肌电图（EMG）活动的影响。
共有26名无腰腿痛的健康参与者，以随机顺序接受每种治疗，两次治疗之间至少间隔48小时。收集P1时的基线ROM HF和半腱肌的EMG幅度。然后，受试者接受361或362分钟的摆动式终末范围（IVz级）直腿抬高（SLR）神经动力学治疗，并重新评估基线指标。
在P1时，两组之间的EMG幅度（P = 0.190）和ROM HF（P = 0.739）无显著差异。两组内P1时的EMG幅度也无显著差异（P = 0.182）；然而，与基线读数相比，两组在P1时的ROM HF均有显著改善（P = 0.000），361分钟组和362分钟组分别增加了6.7°和5.1°。
研究结果表明，在P1时，362分钟的摆动式IVz级SLR神经动力学治疗在ROM HF或半腱肌的EMG幅度方面并不比361分钟的治疗有额外益处。然而，使用摆动式SLR治疗可能有助于增加无痛ROM HF，尽管需要进一步研究来证实这一点。
