Dry Needling With Percutaneous Electrical Nerve Stimulation and Exercises for Non-specific Chronic Neck Pain

Patients assigned to this group (n=50) will receive an intervention in which PENS will be applied for 30 minutes with low frequency parameters (2 Hz) and a pulse width of 120 μs. After 30 minutes of PENS in both groups, the needle will be removed and a compression will be applied for 90 seconds. Once the compression will carried out, the technique will be concluded. Patients will develop a session of PENS and a session with therapeutic exercise once a week.

These participants (n=50) will engage in an exercise protocol with aerobic, isometric, resistence, strength, and stretching exercises. Participants will perform these exercises with a frequency of 3 times a week for 6 weeks, with each session lasting 30 minutes.
