Brief Summary

In the current clinical and scientific reality, conservative treatment is the most coherent clinical management with a view to the proper rehabilitation of patients with chronic neck pain, with a trend towards the use of therapeutic exercise. However, some uncertainty about the effectiveness of therapeutic exercises still remains, requiring further studies with high methodological rigor, especially with regard to multimodal treatment, such as the combination of therapeutic exercises with photobiomodulation. Thus, the objective of this project is to evaluate the effects of adding photobiomodulation to a program of specific therapeutic exercises for the treatment of individuals with chronic non-specific neck pain. To this end, 60 participants will be randomized into three groups: therapeutic exercise group + photobiomodulation (n = 20), and therapeutic exercise group. There will be 8 treatment sessions and participants will be evaluated before, after the 8 sessions, and 4 weeks after the end of treatment using the Numerical Pain Scale, Neck Disability Index, Catastrophic Thoughts about Pain Scale, and Tampa Kinesiophobia Scale. In the statistical analysis, a linear mixed model will be applied, considering the interaction between the time and group factors. Finally, the addition of photobiomodulation to a therapeutic exercise program is expected to generate clinical improvements for patients with chronic neck pain.

Outcome Measures

Primary Outcomes (2)

  • Functional disability

    The NDI will be used to verify the degree of disability due to neck pain.

    Change from Baseline after 8 weeks of intervention and 4 weeks after the end of the intervention.]

  • Numerical Pain Scale

    The Numerical rating pain scale, a simple, easily administered scale evaluates the perceived intensity of pain, using an 11-point scale from 0, representing 'no pain', to 10, which is the 'worst possible pain'.

    Change from Baseline after 8 weeks of intervention and 4 weeks after the end of the intervention.]

Secondary Outcomes (4)

  • Catastrophic Thoughts about Pain Scale

    Change from Baseline after 8 weeks of intervention and 4 weeks after the end of the intervention.]

  • Kinesiophobia Tampa Scale

    Change from Baseline after 8 weeks of intervention and 4 weeks after the end of the intervention.]

  • The Copenhagen Neck Functional Disability Scale (CNFDS)

    Change from Baseline after 8 weeks of intervention and 4 weeks after the end of the intervention.]

  • Global Perception of Change Scale

    Change from Baseline after 8 weeks of intervention and 4 weeks after the end of the intervention.]

Study Arms (3)

Therapeutic exercise group

ACTIVE COMPARATOR

1.Movements of flexion, extension, inclinations, and rotations of the cervical region at maximum amplitude and without load. 2.Neural mobilization of the cervical nerve roots. 3.Contraction of the deep muscles of the flexors, extensors, and rotators of the cervical region without performing spinal movements, using the movement of the eyes to aid in the accomplishment of these exercises. 4.Isometric contraction of the flexor muscles, inclinators, and rotators against manual resistance of the physiotherapist. 5.Isometric contraction of the cervical extensors of the cervical region against gravity. 6.Contraction of the flexor muscles, extensors, and incliners of the cervical region against the resistance of elastic bands.

Other: Therapeutic exercise

Therapeutic exercise group + high frequency TENS

EXPERIMENTAL

This group will consist of 25 participants. Initially, TENS (Endophasys® - NMS-0501, KLD Biosistemas® Equipamentos Eletrônicos Ltda) will be applied to the cervical region through 4 silicon-carbon electrodes measuring 4 x 4 cm, with a water-based gel to reduce impedance at the skin-electrode interface. Thus, TENS will be applied with a rectangular, biphasic, and symmetrical pulse, with a pulse width of 100 µm, a frequency of 100 Hz, at the maximum tolerated sensitive threshold, for 30 minutes (VANCE et al., 2012). After the application of TENS, the same program of therapeutic exercises applied in the first group will be applied, in the same sequence, evolution, times, and repetitions.

Other: Therapeutic exerciseOther: Therapeutic exercise group + high frequency TENS

Therapeutic exercise group + Interferential

EXPERIMENTAL

This group will consist of 25 participants. Initially, the protocol of exercises performed in the therapeutic exercise group will be applied. In sequence, the interferential current will be applied. Through the Endophasys® device - NMS-0501, KLD Biosistemas® Equipamentos Eletrônicos Ltda). Four electrodes (8x5 cm), two upper and two lower (forming a square) will be positioned around the center of the neck. The electrodes will be positioned crosswise, following the parameters: 4KHz (carrier frequency), 1/1 second (Sweep Mode), 60 Hz Amplitude of frequency modulation (AMF), 30 Hz (Delta AMF), automatic vector mode, with intensity at the motor threshold of sensation, lasting 30 minutes (Albornoz-Cabello et al., 2019).
