INYBI Tool in Chronic Neck Pain

University of Seville58 enrolled

Overview

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.

Neck Pain

Interventions

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 inhibitionOTHER

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.

Inclusion Criteria: * Clinical diagnosis of non-specific mechanical neck pain. * Pain of more than 3 months of duration. * Pain between the occiput and the third dorsal vertebra. * Willingness to participate in the treatment and in the follow-up measurements * Neck pain reproduced by neck movements or palpation Exclusion Criteria: * Cognitive impairment or inability to communicate. * Having received manual therapy in the last two months before recruitment. * Having received anti-inflammatory treatment, antidepressants or muscle relaxants in the last 72 hours. * Any contraindication to treatment or evaluation procedures. * Diagnosis of systemic diseases * Diagnosis of fibromyalgia * Pregnancy * Signs of spinal nerve root compression * Previous whiplash * Any diagnosed possible cause for their neck pain (infection, cancer, spinal stenosis)

Outcomes

Primary Outcomes

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

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