Objectives: Establishing and validating an electrotherapy procedure with interferential current (IFC) application using electro-massage on patients who have undergone acromioplasty surgery. To evaluate the possible decrease in pain perception and improvement of functionality following surgical intervention.
Design: Randomized, single blind clinical trial. Subjects: 18-patients, aged 18 to 65, with a similar distribution of male and female participants Methods: 10-patients will be enrolled in the experimental group and 8 patients as the control group. Both groups of patients will undergo six physiotherapy sessions (three times a week). The experimental group will undergo a treatment consisting of electro-massage with constant voltage (CV) IFC bipolar application, 4000 Hz carrier current and 100 Hz amplitude modulated frequency (AMF). Two 48 cm2 electrodes will be used. Session length with electrotherapy will be approximately ten minutes.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Electromassage | Experimental | Electromassage and conservatory treatment. All subjects will be received a conservatory treatment (1h and 40 min) and electro-massage (10min). The protocol will consist of six sessions, twice a week for three weeks. The duration will be 1 hour and 40 min for the conservatory treatment and 10 min for the electro-massage. |
|
| Conservatory Treatment | Active Comparator | The control protocol will combine: (a) thermotherapy with infrared application; (b) active, self-assisted and isometric shoulder exercises, including Codman's pendulum exercises; (c) manual therapy, always in a pain-free range of movement; and (d) ultrasound in pulsatile mode over the acromium and scapulohumeral area. |

| Electromassage | Other | Electro-massage that will be performed by a specialist physiotherapist with more than 8 years of experience We use ENDOMED 482 (Enraf Nonius, Spain) for the elecro-massage. the current parameters are: frequency shift at 4000 Hz IFC, 100 Hz AMF in CV mode. We will gradually raise the current intensity until reaching a high level, but not so high as to cause pain or discomfort, nor evident muscle contraction, although a gentle vibration is allowed. The electro-massage was performed on the musculature of the shoulder and neck. |

| Pain level, assessed by Visual Analogue Scale | This scale is the most accepted to calculate pain level. The range is from 0 (no pain) to 10 (hard pain). | Change from Baseline Pain level at 3 weeks |

|---|---|---|
| Functional evaluation, assessed by Constant Scale. Reference: Constant CR, Murley AH. A clinical method of functional assessment of the shoulder. Clin Orthop Relat Res. 1987 Jan;(214):160-4 | This scale is the most accepted at European level. It calculates pain, activities of daily living, mobility and strength. It is a scale validated by the European Society of Shoulder and Elbow Surgery. Several subscales are combined to compute a total score. |
| Measure | Description | Time Frame |
|---|---|---|
| Range of shoulder´s motion (ROM) | The flexion, extension, abduction, adduction, internal and external rotation were analyzed. They were measured by goniometer (iPhone app). | Change from Baseline ROM at 3 weeks |
