Eligibility
Inclusion criteria
Inclusion criteria: Individuals of both sexes; clinical diagnosis of chronic neck pain defined as persistent pain in the cervical region for more than 12 weeks; pain intensity equal to or greater than 3 points on the Visual Numerical Scale (VNS) at the time of screening; able to perform therapeutic exercises and repetitive peripheral magnetic stimulation (rPMS) sessions; signed Informed Consent Form approved by the Research Ethics Committee
Exclusion criteria
Exclusion criteria: Diagnosis of specific cervical pain of severe structural origin such as herniated disc with root compression; symptomatic spinal stenosis; vertebral fractures; cervical spine tumors; cervical surgery or invasive procedures (infiltration or nerve block) within the last six months; presence of metallic implants or pacemaker in the cervical region contraindicating the use of rPMS; degenerative neurological diseases (e.g., multiple sclerosis, severe peripheral neuropathies); active inflammatory rheumatic diseases (rheumatoid arthritis); skin hypersensitivity; cognitive impairment; other decompensated neurological and systemic pathologies; mandibular and/or palatal torus; undergoing orthodontic, speech therapy, or otorhinolaryngological treatment; continuous or prolonged use of anti-inflammatory medications due to potential interference with pain and inflammation outcomes evaluated in the study
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome of this study will be the combined clinical improvement in pain and cervical functionality in individuals with chronic neck pain. This improvement will be assessed by a reduction of at least 2 points on the Numerical Pain Rating Scale (NPRS) and a reduction of at least 10 points on the Neck Disability Index (NDI), comparing data collected before the intervention and 2 weeks after the completion of the therapeutic protocol. For the improvement to be considered significant, the participant must demonstrate simultaneous reduction in both parameters. | — |
Secondary
| Measure | Time frame |
|---|---|
| Increase in cervical isometric strength, measured by digital dynamometry with a minimum increase of 10% in peak force values ;Reduction in pain sensitivity, evaluated by digital algometry in the cervical muscles, with a minimum increase of 10% in pressure pain threshold ;Modulation of muscle activity, observed by surface electromyography (EMG) in the cervical and masticatory muscles, with improvement in symmetry and reduction of inappropriate muscle co-activation | — |
