简要总结
The flexibility of the hamstrings is a very important component both for general health and when exercising. The lack of hamstring flexibility has been related to the increase in the likelihood of suffering a large number of musculoskeletal pathologies, due to the possibility of causing important muscle imbalances, which include lumbar spine pathologies, such as disc hernias or spondyloarthrosis. In addition, the decrease in the flexibility of the hamstring musculature is also related to the increased likelihood of suffering muscle strains, patellar tendon tendinopathies, femoropatellar syndrome and decreased lumbopelvic rhythm.
Clinically, an invasive technique has appeared, known as Ultrasound-guided Percutaneous Neuromodulation (PNM). This minimally invasive intervention consists in the application of a percutaneous electrical stimulation (PES) through an acupuncture needle-like electrode that is placed in close proximity to the nerve or motor point of the muscle with ultrasound guidance. At the clinical level, the PES is always used with the therapeutic aim of relieving chronic pain and neuropathic pain. Similarly, in sports, PES is used with the aim of improving muscular activity. Therefore, according to the characteristics and the therapeutic benefits of this technique, further research is needed to discover multiple clinical indications.
The aim of this study was to examine the effects on flexibility and strength of an ultrasound-guided percutaneous neuromodulation intervention in patients with shortening of the hamstring muscles.

研究组 & 干预措施
PNM group
Subjects were treated only once. Specifically, this consisted in the application of a square wave biphasic electrical current, with 10 Hz frequency, a 250µs pulse width, and the maximal tolerable intensity to cause an exacerbated muscle contraction for a total of 1.5 mins, according to the protocol (Valera & Minaya). The subjects were lying prone in decubitus. The middle part of the sciatic nerve was located using an ultrasound machine (cross section), then an acupuncture needle (0.30 mm x 40 mm) was inserted in a short axis approach, perpendicular to the surface of the skin, to the perineurium of the sciatic nerve.
干预措施: Ultrasound-guided Percutaneous Neuromodulation (Other)
Control group
The subjects were lying prone in decubitus. The same puncture protocol was performed on the sciatic nerve for 1.5 minutes, but without the application of electricity.
干预措施: Ultrasound-guided Percutaneous Needle (Other)
结局指标
主要结局
Change from Passive Knee Extension 90º [PKE 90º] [Hamstring Flexibility test] 5 minutes after intervention
时间窗: Baseline and 5 minutes after intervention
Passive Knee Extension with hip 90º. The examiner will measure the popliteal angle (between the femur and the tibia) with a goniometer.
次要结局
- Change from Stand and Reach Flexibility Test [Hamstring Flexibility test] 5 minutes after intervention(Baseline and 5 minutes after intervention)
- Change from Sit and Reach Flexibility Test [Hamstring Flexibility test] 5 minutes after intervention(Baseline and 5 minutes after intervention)
