The Use of Diadynamic in Association With a Manual Therapy Program for Patients With Impingement Syndrome

Study Overview
=================
Brief Summary
-----------------
The aim of this study will be to evaluate the effects of the use of manual therapy and diadynamic in muscle trigger points in the upper trapezius muscle in individuals diagnosed with shoulder impingement syndrome, unilateral shoulder as functional capacity, pain intensity and pain threshold the pressure.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Group manual therapy + diadynamic<br>Initially, the positional release techniques will be performed while maintaining this position for 90 seconds procedure is repeated 3 times. Then, the therapist performs the ischemic compression technique on the myofascial trigger point, the compression is maintained for 90 seconds by 3 replications. Through an electrotherapy device were applied diadynamic in that myofascial trigger point previously marked. 4 minutes from the fixed two-phase mode will be applied (DF), 4 minutes long periods (LP) and 4 minutes short periods (CP), the first and second intensely in the sensitive line and the third motor threshold, both supportable according to each patient. | Other: manual therapy<br>* the positional release techniques will be performed while maintaining this position for 90 seconds procedure is repeated 3 times.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| shoulder disability | questionnaire of quality of life developed to assess pain and associated with specific inability to shoulder disorders. | Change from Baseline in the Shoulder Pain and Disability Index at 4 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| intensity of pain | the Numerical rating pain scale, a simple, easily administered scale evaluates | Change from Baseline in The Numerical rating pain scale at 4 weeks | 
| level of pressure pain | Pressure Pain Threshold in the shoulder with algometer dynamometer. | change from Baseline in ThePressure Pain Threshold at 4 weeks |
