Brief Summary

The knee is a common source of musculoskeletal pain, with patellofemoral pain (PFP) standing out due to its high prevalence. This pain, frequent in adolescents and athletes, significantly impacts the quality of life by hindering daily activities such as climbing stairs and sitting for extended periods. Percutaneous neuromodulation of the saphenous nerve (PNM) emerges as a promising therapeutic approach in physiotherapy to alleviate these symptoms. A randomized controlled clinical trial is proposed in adults with PFP. Participants will be divided into two groups: one will receive PNM of the saphenous nerve, while the other will be a control group receiving puncture without electrical stimulation. Pain, extension strength, and knee range of motion will be evaluated before and after the intervention using the AKPS scale. Three sessions will be conducted with specific intervals, and a follow-up assessment will be performed three months later.

Outcome Measures

Primary Outcomes (1)

  • Patellofemoral Pain

    To quantify "pain intensity," the Visual Analog Scale (VAS) will be used, allowing the patient to subjectively express the intensity of their pain. It consists of a 10 cm line, where one end represents complete absence of pain and the other end represents the maximum possible intensity of pain. The patient is asked to mark on the line the point that reflects their pain level, and the measurement is recorded in millimeters. Within the "pain intensity" variable, a sub-variable will record the difference in pain intensity before and after the invasive physiotherapy intervention, expressed as a percentage of relief. This approach will allow observation of pain evolution across different sessions and evaluation of the immediate effects of Percutaneous Ultrasound-guided Neuromodulation.

    Before and after the puncture in all interventions. Up to 4 months

Secondary Outcomes (1)

  • Knee functionality

    Before the puncture in all interventions. Up to 4 months

Other Outcomes (2)

  • Strength of the knee

    Before and after the puncture in all interventions. Up to 4 months

  • The range of motion of the knee

    Before and after the puncture in all interventions. Up to 4 months

Study Arms (2)

PNM group

EXPERIMENTAL

Participants in the experimental PNM group will receive ultrasound-guided percutaneous neuromodulation of the saphenous nerve in the painful leg. In this study, a neurostimulation device ITO ES-160 will be used, where parameters of 2 Hz, 250 μs, and 16 minutes of continuous current will be set, with an appropriate intensity for subjects to perceive nerve stimulation along the path of the nerve (from the needle insertion point to the anterior aspect and below the knee), always ensuring it remains tolerable for them. No motor response will be observed. The black clip of channel 1 will be attached to the needle, and a TENS patch will be attached to the red clip. The interventions will be conducted 3 times, with 1 week between the first two and a 2-week interval between the second intervention and the third. All measurements will be taken before and after the procedure.

Diagnostic Test: Ultrasound-guided percutaneous neuromodulation

NON-PNM group

PLACEBO COMPARATOR

Participants in the control NON-PNM group will receive saphenous nerve puncture in the injured leg with subsequent placement of the clamps but without activating the electrostimulation function. The needle will remain without current for 16 minutes. The interventions will be conducted 3 times, with 1 week between the first two and a 2-week interval between the second intervention and the third. All measurements will be taken before and after the procedure.

Diagnostic Test: Ultrasound-guided percutaneous neuromodulation

Interventions

Percutaneous ultrasound-guided neuromodulation of the saphenous nerve in subjects with patellofemoral pain to assess its positive effects on pain and functionality.

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Be 18 years or older.
