About

This project will analyze the influence of interferential current therapy in an exercise program for individuals with a unilateral impact syndrome diagnosis. To that end, volunteers of both genders, aged 18-59 years, had an unilateral, unilateral pain in the shoulder with more than 3 months duration, at least grade 4 pain by the numerical scale of pain assessment, positivity In at least 2 of 3 orthopedic tests for impact syndrome, will be randomized into the following groups: exercise group, exercise + ultrasound group, exercise group + interferential current. Sixteen consecutive treatment sessions will be performed, and the volunteers will be evaluated before and after, by means of the following instruments: Numerical scale of evaluation of pain, Shoulder pain and disability index (SPADI), Pain-Related Catastrophizing Thoughts Scale, being applied the Numerical scale of evaluation of pain at the end of Each session and one month after the end of treatment.

Enrollment: 45 patients

Sex: All

Ages: 18 to 59 years old

Volunteers: No Healthy Volunteers

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Double Blind

---

45 participants in 3 patient groups, including a placebo group

exercise group

Active Comparator group

Description:

Manual cervical traction, Myofascial release of upper trapezius muscle, 3 sets of 1 minute;Sleeper's stretch, during 3 series of 30 seconds,Punch exercise, Knee push-up plus, Prone V-raise exercise (arms abducted at 120°), rotador cuff exercise (internal rotation), rotador cuff exercise (external rotation), Rotation on the wall using a ball (internal rotation), Rotation on the wall using a ball (external rotation).

Treatment:

Other: exercise

exercise + Interferential current group

Experimental group

Description:

Addition to the exercise protocol performed in the exercise group the interferential current. Four self-adhesive electrodes (8x5 cm), two upper and two lower ones (forming a square) will be placed around the center of the shoulder. The electrodes will be positioned crosswise, following the parameters: 4KHz (carrier frequency), 1/1 second (swing pattern), 100 Hz Frequency modulation amplitude (AMF), 50 Hz (sweep frequency), automatic vector mode, With intensity at the motor threshold of sensation, with duration of 50 minutes.

Treatment:

Other: exercise

Device: Interferential current therapy

exercise + US group

Placebo Comparator group

Description:

In addition to the exercise protocol performed in the exercise group, an ultrasound device will be used. The appliance will be used off, without any individual participant having knowledge. For this, the individual will be asked to position himself in the dorsal position on the stretcher, the therapist will perform the application of the transducer head, with gel on its surface, in the anterolateral region of the affected shoulder.

Treatment:

Other: exercise

Device: Therapeutic Ultrasound
