Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
CF training focuses on constantly varied functional movements, including gymnastics, weightlifting exercises, and cardiovascular activities (e.g., running or rowing). Variety is one of the main attractions for participants, as the workouts are short, intense, and diverse.
Within invasive physiotherapy, there is the technique of ultrasound-guided percutaneous neuromodulation (US-PNM), which enhances muscle function, muscle recruitment patterns, and motor control. This minimally invasive intervention involves the application of percutaneous electrical stimulation through an electrode similar to an acupuncture needle, placed in close proximity to the nerve or motor point of the target muscle under ultrasound guidance. Performing this technique under ultrasound guidance is recommended as it makes the procedure safer and more effective, allowing real-time visualization of needle positioning and technique application.
Most studies on US-PNM have focused on pain treatment in patients, but some studies have explored its benefits in healthy individuals. For instance, De-la-Cruz-Torre et al. demonstrated that applying this procedure to the sciatic nerve can increase hamstring flexibility; De-la-Cruz-Torres et al. also reported an increase in the performance of the flexor hallucis longus muscle in dancers; Álvarez-Prats et al. showed an improvement in quadriceps muscle strength after performing electrical stimulation on the femoral nerve; and Gallego-Sendarrubias et al. suggested an enhancement in performance skills in soccer players by applying the neuromodulation procedure to the femoral nerve before specific strength training.
Overall, the literature suggests that US-PNM intervention improves strength levels, but the results should be confirmed with future research due to sample size limitations and short-term evaluations. Additionally, there are currently no studies on the application of US-PNM in a sample of CF athletes. Therefore, the objective of this study is to analyze the effectiveness and duration of the effects of two US-PNM protocols applied to the axillary and suprascapular nerves on shoulder rotation strength in healthy CF athletes.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* Analyze whether 3 sessions of ultrasound-guided percutaneous neuromodulation (US-PNM) are more effective than 1 session of US-PNM for shoulder rotation muscle strength in healthy CrossFit athletes.
* Analyze whether the US-PNM intervention has a positive effect on the ability to perform a one-repetition maximum (1RM) in a functional CF movement, such as the "Shoulder Press," in healthy CrossFit athletes.
To achieve this, a randomized clinical trial is proposed with three study groups:
* Control group: no intervention will be performed.
* Experimental group 1 session US-PNM: will receive 1 session of US-PNM.
* Experimental group 3 sessions US-PNM: will receive 3 sessions of US-PNM, with one week of separation between each session.

NMP-e 3 sessions
The group receives 1 session of ultrasound-guided percutaneous neuromodulation. The session wil be received at day 1 of the study.
NMP-e
The US-PNM intervention uses a square-wave biphasic current (10 Hz, 250 ms pulse width) at maximum tolerable intensity for 1.5 minutes (10 seconds 10 times), per Fermín Valera and Fran Minaya's protocol. Participants will lie on their side, with the area cleaned and an ultrasound probe cover used.
Needles (Agu Punt, Spain) will be inserted perpendicularly to target the nerve perineurium. For the axillary nerve (C5-C6), a 0.40/0.50×25 mm needle will be used in a short axis at 80°. For the suprascapular nerve (C5-C6), a 0.30/0.40×25 mm needle will be used.
Each session involves two needle insertions, with the needle stationary and monitored by a physiotherapist with two years of experience.
NMP-e 1 session
The group receives 3 sessions of ultrasound-guided percutaneous neuromodulation. The sessions wil be received at day 1, 7 and 14 of the study.
