This study evaluates the improvement of patients with whiplash injury by comparing two statistical groups: a control group with exercise alone and an experimental group with exercise and percutaneous musculoskeletal neuromodulation of the accessory nerve. The following variables are evaluated: Neck Disability Index, VAS, cervical ROM, and algometry in the upper trapezius.

|---|---|---|---|
| Control Group: Only exercise | Active Comparator | This arm just do exercise, controlled by a phisiotherapist, This group had 13 different exercises. |

| Exercise | Other | The intervention were 13 different exercises. Of the 13 exercises, 6 are specific activation and strength exercises targeting the deep neck muscles, whilst 7 are general neck strength and endurance exercises. The total duration of the programme will be 40 minutes. Following the first session of the exercise programme, a further session was scheduled for later in the week. |

|---|---|---|
| Neck Disability Index (NDI) | It is a scale that measures neck disability in patients with non-specific neck pain. The scale include 10 questions of 6 items with a score from 0 to 5. 0 means no limitation and 5 great limitation. The scores are added up and through indirect proportionality a percentage is obtained, with 0% being absence of pain and disability and 100% being maximum pain and disability. | From enrollment to the end of the treatment at 4 weeks |
| Measure | Description | Time Frame |
|---|---|---|
| Pain threshold in the ascending fibres of the trapezius muscle | To measure the pain threshold of the ascending fibres of the trapezius muscles, pressure algometry was performed on the point of greatest pain described by the patient in the ascending fibres of the trapezius muscles using a conventional algometer. | From enrollment to the end of treatment at 4 weeks |

| Ultrasounded Percutaneous Neuromodulation | Other | This procedure involved inserting a needle into contact with the epineurium of the accessory nerve at neck level and applying electrical stimulation. With the aid of an ultrasound scanner, the physiotherapist performing the procedures approached the epineurium of the accessory nerve using a solid needle (Agupunt® brand, 0.30 mm × 0.40 mm). Stimulation was performed using a compensated biphasic low-frequency current with a frequency of 2 Hz and a pulse width of 250 microseconds for 20 minutes using the FisioInvasiva® 2.0 device (PRIM, Madrid, Spain) via PES (Percutaneal Electrical Stimulation) currents and an electrode to complete the circuit. The procedure is called Ultrasounded Percutaneous Neuromodulation (US-PNM). |

| Active cervical range of motion (ROM) | Cervical ROM was measured using a conventional two-arm goniometer, recording active movements of flexion, extension, left and right lateral flexion, and left and right rotation. | From enrollment to the end of treatment at 4 weeks |
| Pain intensity measured using VAS | The VAS is a scale used to assess patients' pain intensity. The VAS consists of a straight line measuring 10 centimetres, where the left end is 0 (no pain) and the right end is 10 (the worst pain imaginable). Participants will indicate on the line the point that best reflects the intensity of their pain at the time of assessment. | From enrollment to the end of treatment at 4 weeks |
