Ankle sprain is a common injury. Around 712,000 sprains occur every day in the world. It is estimated that they account for 45% of sports injuries, being the second part of the body that is most frequently injured in sports. Of the patients who suffer this injury, around 70% will develop chronic ankle instability, a situation that can cause residual pain, recurrent sprains, a feeling of lack of stability and decreased physical activity. Two entities can be included in chronic ankle instability: mechanical instability, which involves movement of the joint beyond its physiological limit, and functional instability, which includes proprioceptive dysfunction, impaired neuromuscular control, postural control, and strength deficits. Currently, the conservative treatment of these patients consists of neuromuscular training through the use of dynamic balance platforms, taping, joint mobilization, dry needling, and the use of plantar supports, balance training being the one that has shown the best result. Ultrasound-guided percutaneous neuromodulation (PNM) is a recently used technique in the field of invasive physiotherapy that consists of applying a square wave biphasic electrical current through an acupuncture needle-like electrode that is place in close proximity to the nerve with ultrasound guidance. The aim of this study is to evaluate the effectiveness of PNM in ankle instability.

Cumberland ankle instability tool
The Cumberland ankle instability tool (CAIT) is a questionnaire that consists of 9 items, the maximum score of the questionnaire is 30 points, the lower the score obtained, the more severe the functional instability of the ankle. The Spanish version of the CAIT has high internal consistency (Cronbach's α00.766) and reliability (intraclass correlation coefficient 0.979, 95 % confidence interval (CI) 0.958-0.990).
Time frame: Change from Baseline up to three months
Byodex Balance System (BBS)
The BBS is a platform designed to measure and record an individual´s ability to maintain stability under dynamic stress. It calculates a medial-lateral stability index (MLSI), anterior-posterior stability index (APSI), and an overall stability index (OSI) with reliability estimates of R= 0.92 (OSI), R = 0.89 (APSI), R= 0.93 (MLSI).
Time frame: Change from Baseline up to 5 minutes
Electromyography muscle (EMG)
Mdurance EMG system is valid tool to measure muscle activity during isokinetic contractions. It has shown an almost perfect Intraclass Correlation Coefficient\>0.81.
Time frame: Change from Baseline up to 5 minutes
stiffness tissue
Myoton Pro is a device designed to measure and record Oscillation frequency (pitch), dynamic stiffness (stiffness), logarithmic decrement (elasticity), mechanical stress relaxation time and creep. It has shown an excellent reliability, Intraclass Correlation Coefficient 0.91-0.96 in all measures with the exception of elasticity 0.78-0.86
Time frame: Change from Baseline up to 5 minutes
