Eligibility
Age
18 Years to No maximum
Inclusion criteria
Inclusion criteria: Men or women aged 18 or over; diagnosis of trigger point in the upper trapezius muscle by the diagnostic criteria according to the consensus described in the study by Fernandez-De-Las-Penas and Dommerholt (2018), in which three criteria are established: two manual findings (a tense band and a hypersensitive point) and a symptom (referred pain, with characteristic depth and irradiation), requiring the presence of one of the manual findings and referred pain for the diagnosis to be positive.
Exclusion criteria
Exclusion criteria: neck or shoulder trauma; diseases that contraindicate the use of laser; surgery history; refusal to perform the assessment and intervention after randomization
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Decreased pain intensity, verified through the numerical visual scale (NVS), which consists of a linear scale from 0 to 10 points, where the volunteer quantifies his pain according to the numbers on the scale. The absence of pain is quantified with the number 0 and the most intense pain that the individual has ever felt corresponds to the number 10. The decrease in pain will be determined by the difference of at least 1.6 points in the pre- and post-intervention measurements. | — |
Secondary
| Measure | Time frame |
|---|---|
| Improvement in neck functionality, verified through the Neck Disability Index (NDI). This is an instrument used to assess the functionality of the cervical region during Activities of Daily Living. The questionnaire consists of 10 questions related to general activity and pain. Topics are organized by type of activity, followed by six different statements, expressing progressive levels of functional capacity. The NDI score consists of the sum of 0 to 5 points for each of the 10 questions, totaling a maximum of 50 points. Upon completion, the total score is divided by the number of questions answered and multiplied by the number 5. The result of this division is multiplied by 100, and the final value is expressed as a percentage, ([score ÷ (number of questions answered x 5) ] × 100). Therefore, when the value is less than 10%, it is considered that there is no disability; from 10 – 28%, disability is minimal; from 30 – 48%, moderate disability; from 50 – 68%, severe disability; and above 72%, complete disability. The improvement in neck functionality will be confirmed by the minimum difference of 3.5 points in the pre- and post-intervention measurements.;Perception of improvement after the intervention, verified through the Perceived Global Effect (PGE) questionnaire. This tool consists of evaluating the volunteer regarding changes in their clinical condition in a predetermined time, and can be presented on a numerical scale or in qualitative alternatives. In our study, the numerical scale will be applied, with a variation between -5 and 5, where -5 means an extreme worsening in their condition and 5 completely recovered, that is, on this scale, the higher the score, the greater the improvement in the volunteer's condition. The perceived improvement will be verified if the participant reports a perception of improvement in their clinical condition. | — |
