Comparison of Two Stretching Techniques in Patients Suffering From Subacromial Syndrome

Not Applicable

• Conditions: Subacromial Impingement Syndrome
• Interventions: Procedure: Short Lever Group; Procedure: Long Lever Group

• Registration Number: NCT04073199
• Lead Sponsor: Fundacio d'Investigacio en Atencio Primaria Jordi Gol i Gurina

Brief Summary

The shoulder stability has always been related to the rotator cuff complex, although more and more is contemplated the Teres Major muscle and its affectation in the shape of the trigger points within this pathology. As non-invasive measures for the deactivation of these myofascial points, Travell and Simons recommended the pressure maintained along with muscular stretch.

Stretching are usually a technique widely used in our practice as physiotherapists and it is necessary to study its effects in the clinic. As an objective we plan to compare the effect of passive stretching in short lever according to the Orthopaedic Manual Therapy concept if it produces better result in the pain, the rank of movement and in the Function, with the effect of stretching by means of a long lever in affected patients of subacromial syndrome.

This is a randomized controlled study with blind evaluator approved by the Ethical Committee of the Institut d'Investigació en atenció Primaria Jordi Gol.

After checking the inclusion and exclusion criteria, you will be asked, voluntarily, that the patient sign informed consent. The variables will then be valued independent and dependent on the study. It will randomly be assigned to one of the three groups in the study. The 3 groups receive the protocolized treatment for the service they consist of In superficial thermotherapy, an educational talk and kinesitherapy. The intervention groups will receive alternate days, with a total of six sessions, the stretch corresponding to the group to which they have been assigned.

In the case of the Long Lever Group, the intervention consists in a rotary stretch through the humerus as a mobile point. And in the case of the Short Lever Group a stretch of translocation through the scapula as a mobile point.

The main variables used will be: age, side effects, habits involving the shoulder, pain intensity, pain threshold at pressure and function, among others. The dependent variables will be measured: pain intensity by means of Analogue Scale Visual, the function through the Constant-Murley test, the Movement Range with Goniometer and the Pressure Threshold Pain with a pressure gauge brand Stech.

Arm && Interventions

Group	Intervention	Description
Short Lever Group	Short Lever Group	This arm receive the protocolized treatment along with the short lever stretch according to the Orthopaedic Manual Therapy of the Teres Major.
Long Lever Group	Long Lever Group	This arm receive the protocolized treatment along with the long passive stretch of the Teres Major in Long Lever with the patient in supine position.

Primary Outcome Measures

Name	Time	Method
Threshold Pressure Pain	5 minutes needed for explain the technique and realise it.	The patient will be placed in a chair with a table in front, where can support the elbow and forearm in shape comfortable. The physiotherapist takes a clamp without pushing the Teres Major muscle and will perform progressive pressure with the algometer until the patient refers pain sensation.; The subjects who perceive pain with a threshold of pressure below 2kg / cm2 will be included in the study according to Andersen et al
Function	10 minutes needed for the realization of the test	The assessment of the function will be performed through the constant Constant-Murley test.; The Constant-Murley test abbreviated is a scale that measures the function of the shoulder on the basis of three components: pain, mobility and activities of daily life, resulting in a value maximum of 75 points, in the case that there is no limitation.
Active Mobility	10 minutes needed for explain the movements required and make de measurements.	The measurement of active mobility (active flexion, active extension, active abduction, active external rotation, active internal rotation) will be done in standing position with the back supported in the framework of a door (to unify positions and allow us to carry out the extension) with a goniometer for flexion, extension, abduction and external rotation, and with a tape metric for internal rotation (measurement from the thumb to the spinous process of C7)
Pain Intensity	2 minutes needed for the explanation and the realization of the measure.	It will be measured using an Analog Visual Scale. The scale to be used, always the same in each measurement.
