INYBI Tool in Chronic Neck Pain

Objectives: To evaluate the clinical efficacy of using a manual inhibition technique for the suboccipital muscles compared with the use of the so-called INYBI tool in individuals with chronic non-specific neck pain, and the compare the results of using both approaches on pain relief, cervical range of motion neck and vertical maximum mouth opening.

Design: Quantitative, experimental, longitudinal, prospective, and double blinded study.

Subjects: Patients between 18 and 40 years, with chronic non-specific neck pain of at least 3 months of evolution.

Methods: The experimental group will undergo a 5 minutes intervention for the suboccipital muscles using the INYBI tool. The control group will receive a 5 minutes of treatment involving the suboccipital muscles manual inhibition technique.

  • Signs of spinal nerve root compression
  • Previous whiplash
  • Any diagnosed possible cause for their neck pain (infection, cancer, spinal stenosis)

Treatment and study plan

INYBI tool

Device

Patients will lie down in supine position so that the INYBI tool will contact the suboccipital muscles at the posterior arch of the atlas. The therapist will adapt the height of the tool for each individual. All patients will use the softest head of the device. A 50Hz vibration speed will be set sup during 5 minutes.

Manual suboccipital inhibition

Other

Patients will lie down in supine position.The therapist will be seated at the head of the treatment table. The therapist will keep the metacarpophalangeal joints in a flexed position, while therapists fingertips of both hands will contact with the suboccipital muscles at the posterior arch of the atlas.

Primary outcomes

  1. Pressure pain threshold (PPT) in the evaluated muscles. The PPT levels will be evaluated in Kilograms / cm2

    Time frame: From baseline to immediately after treatment.

    PPT levels, defined as the minimum necessary pressure to evoke pain will be evaluated using a handheld electronic pressure algometer.

  2. Active cervical range of movement (ROM). The range of movement will be assessed in degrees

    Time frame: From baseline to immediately after treatment.

    Flexion, extension, left and right side flexion, and left and right rotation will be assessed using a digital inclinometer.

  3. Pain free vertical mouth opening. This outcome will be evaluated in centimeters.

    Time frame: From baseline to immediately after treatment.

    Maximum pain free vertical mouth opening will be assessed using a digital caliper that will place between the incisors 11, 21, 31 y 41.

  4. Atlas rotation ROM, assessed in degrees

    Time frame: From baseline to immediately after treatment.

    The atlas bone left and right rotation ROM will be assessed using the flexion-rotation test. For this test, with the participant in supine position, the maximum mobility in head rotation while keeping maximum passive neck flexion will be assessed

  5. Self-reported pain intensity

    Time frame: From baseline to immediately after treatment.

    Self-perceived pain intensity will be evaluated during all active cervical movements by a 0 to 10 Visual Analogue Scale (VAS), where 0 denotes no pain at all, and 10 denotes the maximum possible pain
