Neck pain is a prevalent musculoskeletal dysfunction. Studies point that individuals with chronic pain have metabolic, vascular and electromyographic changes in trapezius muscle. Moreover, a common clinical sign in this muscle in subjects with neck pain is the presence of myofascial trigger points. These are related to the sensory, motor and autonomic changes, being defined as palpable nodules located in the taut band of skeletal muscle. In this context, the focus on treatment modalities stands out in the literature, however, other resources commonly used in clinical practice still lack scientific evidence. Therefore, the aim of this project is to evaluate the effectiveness of physiotherapy resources in the treatment of myofascial trigger points in the trapezius muscle of patients with neck pain. For such, volunteers with neck pain for more than 90 days, of both genders, aged between 18 and 59 years and bilateral myofascial trigger points in the upper trapezius will be randomized into the following groups: group 1 (kinesiotherapy, n = 20), group 2 (kinesiotherapy + static ultrasound, n = 20), group 3 (kinesiotherapy + diadynamic currents, n = 20) and group 4 (untreated control, n = 20). Volunteers will undergo ten sessions of treatment, being realized the following evaluations: surface electromyography, infrared thermography, numerical scale of pain assessment, algometry, Neck Disability Index and skin impedance. For data analysis, normality test will used to verify the data distribution and consistent statistical test for the appropriate comparisons within and between groups, and thus considered two factors in the comparisons, time and group. Will adopt a significance level of 5%.

Further study details as provided by University of Sao Paulo:

Primary Outcome Measures:
  • Pain [ Time Frame: 3 years ]
    Will be apply the following assessment tools: Neck Disability Index (assesses neck pain and disability), algometry (evaluates pressure pain threshold), and numerical scale of pain assessment (assesses pain intensity).

Secondary Outcome Measures:
  • Cervical range of motion [ Time Frame: 3 years ]
    Through a fleximeter will be evaluated movements of flexion, extension, rotation and inclination of the neck.

  • Skin temperature [ Time Frame: 3 years ]
    Through of thermograph will be evaluated skin temperature on myofascial trigger points.

  • Muscle activity [ Time Frame: 3 years ]
    Through surface electromyography will be evaluated the electrical activity of the upper trapezius muscle.

Estimated Enrollment: 80

Estimated Study Completion Date: June 2017
Estimated Primary Completion Date: June 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Kinesiotherapy group
The volunteer will be subjected to the following protocol: cervical traction, 3 sets of 1 minute, 30-second rest between sets; mobilization grade III postero-anterior on the spines processes of vertebrae C2 to C7, 10 oscillations for each vertebrae; myofascial release of the upper trapezius muscle, 3 sets of 1 minute for each side; static stretching of the upper trapezius muscle, 3 sets of 30 seconds, with an interval of 10 seconds between sets.
Other: Kinesiotherapy
Experimental: kinesiotherapy + static ultrasound group
Same protocol group kinesiotherapy + ultrasound on the trigger points of the upper trapezius muscle in a static way, with 1 MHz, continuous dose of 1.5 W/cm2, for 1.5 minutes.
Other: Kinesiotherapy Other: Ultrasound
Experimental: kinesiotherapy + diadynamic currents group
Same protocol group kinesiotherapy + diadynamic currents, with negative electrode (7.0 x 7.0 cm) placed on the myofascial trigger point, while the positive electrode (7.0 x 7.0 cm) is placed between the shoulder blades. Will apply 4 minutes from the biphasic mode (DF) and 6-minute short period (CP), the first of which intesidade the sensory threshold and the second threshold motor, both bearable for the patient.
Other: Kinesiotherapy Other: Diadynamic currents
No Intervention: Control group
The volunteers of this group will not be subjected to any form of treatment, was evaluated in three stages, as the other groups. It is noteworthy that, after the volunteer's participation, will be offered at the same physical therapy for myofascial pain.
