Brief Summary

The aim of the study is the measurement and comparison of two manual therapy techniques, the Mulligan´s mobilization with movement technique, and de placebo technique, both applicated in patients with subacute neck pain.

Detailed Description

Study design:

A randomized, longitudinal, experimental, prospective, parallel and double-blind clinical trial was conducted, where both the study subject and the researcher performing the measurements do not know which treatment group they belong to. Patients were randomly assigned using GraphPad Software's QuickCals application (La Joya, CA, USA) to one of the 2 study groups: experimental group and placebo group.

Participants:

The sample was composed of 42 sub-acute and inespecific neck pain patients residing in the Community of Madrid, all of whom were recruited personally for the study. Experimental group includes 21 subjects who received a manual theraphy technique named Mobilization with Movement (MWM) for a total of four sessions, distributed in two sessions per week. . Placebo group includes 21 subjects who received a placebo technique the same times.

Measurement instruments:

The primary outcomes of interest were true and total cervical ROM, Pain Pressure Threshold (PPT), pain intensity, Neck Disabilty Index, anxiety scale and depression scale. Secondary outcomes were pain and/or neck stiffnes for musculosketletal causes.

Goniometry

This is the measurement of angles on the arc of motion of a joint. Goniometry is a quantitative variable and numerical and unit of measurement is in degrees.

Measurement of cervical motion was performed with the device CROM (Cervical Range Of Motion) due to the extensive evidence as to its reliability. This device has two gravity goniometers, indicating the mobility in the sagittal and frontal planes (measurement of the flexion-extension and lateral inclination, respectively). For the transverse plane, the goniometer has a compass, a magnet with magnetic resting on the shoulders to measure neck rotation.

Algometry

Consists in measuring the pain threshold pressure, by stimulating the receptors of pressure. This threshold is defined as the minimal amount of pressure that produces pain.

Algometry is a quantitative variable and gives numerical values in Kilograms/cm2.

To study algometry has relied on a digital algometer Wagner Force One Digital Force Gage FDX model 100 with an 1cm2 head. This device, used with a gradually application of manual force and consistently, and prior familiarity with the user, has a high fiability.

• Intensity of pain measured by visual analogue scale (VAS) just before and immediately after treatment.
• Neck disability index: Scale completed by the patient before tratment
• BECK: Scale completed by the patient before tratment.
• STAI: Scale completed by the patient before tratment.
• Mobilization with movement technique: Technique therapy applied to the experimental group.

Procedural protocol:

Measures were collected before and after intervention, stablishing the hypotesys about reasons and inmediate effects in relation with the tecnique applied.

No follows-up will be done to the patients. It is supposed like a bounding factor in that study.

• Goniometric measurements procedure: The patient position for goniometric measurement is similar to the physiotherapist intervention, described previously.

The patient actively and in all range of motion , perform flexion, extension, bilateral lateral flexion and bilateral rotation movements. And then, the therapist will gather the parameters at the end of every movement.

All goniometric measures will be reported three times and the average of three measurements will be calculated.

Goniometric informacion is collected just before the therapeutic intervention and five minutes later.

• Pressure algometer measurements procedure: The patient supine with algometer perpendicular to the exactly point for evaluation, and the pressure is increasing slowly and linearly. The intervention speed applied will be 1kg/cm2/second until the patient feels pain. Just in that moment, the researcher stops pressure.

Hereby a target response is favored due to fact that patient has more reaction time when he starts to feel pain. In that moment, the researcher interrumps exercised pressure with the algometer.

In every anatomical reference, three measures will be performed consecutively in intervals of 30 seconds for measurement to generate an average, neccesary for statical analysis.

Pain pressure threshold measure is performed just before therapeutic intervention and 5 minutes later.

• Anatomical References to study: Bilateral measurement of superior cervical region in spine C2: To plan a horizontal line between spine C2 to both sides, separated 1 cm to the spine point.

Bilateral measurement of superior cervical region in spine C7: To plan a horizontal line between spine C7 to both sides, separated 1cm to the spine point.

Superior Trapezius measurement: Horizontal line between acromion to spine C7 Lateral Epycondile measurement: lateral prominence of distal humeral epiphysis with the superior extremity supported on the table.

The algometer technique is performed just before therapeutic intervention and 5 minutes later.

Study Groups

Mobilization with movement technique

The therapist applies supported pressure on right and left side and articular planes. Meanwhile, the patient executes active movements and the therapist is trying to find the specifies cervical joint to get partial or total painful relief or movements with restrictions.

If the therapist couldn´t relief or remove pain or restriction with the pressure permorfem, he will readjust pressure and slide in differents planes of motion. It is necessary achieve that aim.

After that, the patient stay in sit down raised position on a stool, with his back in contact with the wall.

Hip, knee and ankle of the patient suppor a certain position: 90º of flexion which will be checked with a conventional goniometer. His hands are on the thighs. The treatment lasts 5 minutes.

Group Type: EXPERIMENTAL

Mobilization With Movement Technique

Intervention Type: OTHER

The researcher explains cervical movements to the patient to be done while the technique is performed. This movements will be the painful and limited movements detected in goniometric intervention before the treatment and movements done actively and in all range of motion.

Placebo technique

Placebo manual technique is performed similar to experimental group technique but no slides are performed. The therapist simply embraces cervical region with boths hands, avoiding any pressure or any painfully caoture.

Group Type: SHAM_COMPARATOR

Mobilization With Movement Technique

Intervention Type: OTHER

The researcher explains cervical movements to the patient to be done while the technique is performed. This movements will be the painful and limited movements detected in goniometric intervention before the treatment and movements done actively and in all range of motion.
