Brief summary

The aim of the study is to compare two manual therapy techniques. By testing if the Pressure Release of Myofascial Trigger Points technique (PRM) is more effective in treating Myofascial Trigger Points present in the upper trapezius muscle of patients with mechanical cervical pain. This will be compared mainly with another manual therapy technique that presents evidences such as Ischemic Pressure technique (IP), and a control group, through the evaluation of the Visual Analogical Scale (VAS), the Threshold of Pain at Pressure (TPP) and the Northwick Park Questionnaire (NPC) of neck disability, spanish version.

Detailed description

The present pilot study is proposed as a crossover, controlled and randomized clinical trial, with blinded evaluation of response variables. The aim of the study is to test whether the Pressure Release of Myofascial Trigger Points technique(PRM) is effective in treating Myofascial Trigger Points present in the upper trapezius muscle of patients with mechanical cervical pain. This will be compared mainly with another manual technique that presents more evidence such as Ischemic Pressure (IP), through the evaluation of the Visual Analogical Scale (VAS), the Threshold of Pain at Pressure (TPP) and the Northwick Park Questionnaire (NPC) of neck disability, Spanish version. The patients, with a minimum sample for the pilot study of 30 subjects, of working age (18-50 years) with mechanical neck pain for at least the last month, will be recruited from the clinic Fisioterapia Los Molinos in the town of Getafe, the same place where the treatment will be carried out. They will be randomly divided into three groups: one will be given Pressure Release of Myofascial Trigger Points technique (PRM), another Ischemic Pressure technique (IP), and a last one will be assigned as a control group. In compliance with the corresponding ethical criteria, the three groups will be subjected to random crossover so that no patient is left untreated. Visual Analogical Scale (VAS), Threshold of Pain at Pressure (TPP) and Northwick Park Questionnaire (NPC) of neck disability (spanish version), will be evaluated before and immediately after treatment. Statistical analysis will be performed by IBM SPSS v22.0 program or a later version, verifying that the sample meets the criteria of normality and homogeneity and comparing the results of the variables through an ANOVA Analysis of variance.

Interventions

OTHERPressure Release technique

Manual therapy technique used by the treatment of Myofsacial Trigger points. The therapist will apply it with the first and second finger on the previously marked Myofascial Trigger Point and increasing the pressure as he perceives a reduction in the resistance offered by the soft tissue under the finger

OTHERIschemic pressure technique

Manual therapy technique by making pressure in Myofascial Trigger Point. The therapist will apply it with the first and second finger on the previously marked Myofascial Trigger Point. This is performed until the patient's tolerance, when he refers a decrease in pain or have a correct adaptation to the perceived pain increase the pressure to a new painful barrier.

Masking description

Participants will not know to which group they have been assigned in each of the interventions Participants will be assigned an individual code by which the outcome assessor will not be able to know what treatment(s) each individual received

Intervention model description

Patients, aged 18-50 years with mechanical neck pain for at least the last month, will be randomly divided into three groups: one will be given Pressure Release technique, another Ischemic Pressure technique, and a last one will be assigned as a control group. They will be crosslinked after the first treatment. The variables will be evaluated before and immediately after treatment.

Design outcomes

Primary

MeasureTime frameDescription
Visual Analog ScaleBefore the interventionPlace a mark in a chart according to the state of pain you are in at the moment, taking into account that the left extreme is the absence of pain and the opposite is the worst pain you may suffer
Pain Threshold at PressureBefore the interventionEvaluated with a pressure algometer. It will be assessed with the subject in a comfortable position, back supported by the backrest, feet on the floor and arms relaxed. The algometer will be placed perpendicular to the previously marked Miofascial Trigger Point. Once it is in place, the pressure should be increased one kilogram by second until the patient begins to feel discomfort. At this point the application will be stopped. Three measurements were made and the average will be calculated. Measured by Kilograms per square centimeter
Northwick Park Questionary (Spanish Modified Version) for Cervical Spine disabilityBefore the interventionThe questionnaire consists of nine questions related to pain intensity, sleep, weight load, leisure and social activities, work and driving. Each one of them presents five possible answers graduated from 0 to 4, where 0 represents the absence of disability and 4 the maximum degree of disability.
