Summary

Objective: The investigators aimed to compare the effectiveness of transcutaneous electrical nerve stimulation (TENS) and interferential currents (IC) to improve shoulder functionality and to reduce perceived pain in patients with subacromial impingement syndrome (SIS). Design: Thirty-six patients with unilateral shoulder pain and diagnosed as having SIS were randomly assigned into two groups: TENS (n=18; 51±7 years) and IC (n=18; 47±6 years). Patients in both groups received fifteen 30-min sessions of the assigned treatment for a period of 3 weeks. Before and after the treatment, shoulder pain was measured using a 100-mm visual analog scale and shoulder functionality was measured using the Constant-Murley scale.

Conditions

  • Subacromial Impingement Syndrome

Interventions

DEVICE

Transcutaneous nerve stimulation

The group with TENS received electrical stimulation (Endomed 182, Enraf-nonius, Germany) at a frequency of 80 Hz and with a pulse width of 150 ns. The TENS was applied by using 4 surface electrodes (5x5 cm Prim-Trode, Spain) into two channels: supraspinatus fossa and the insertion of the rotator cuff (channel 1) and "V" deltoid " (channel 2). The current intensity was set 3 times during each session according to each patient's sensitivity. Current was strong but it did not exceed the threshold of pain.

DEVICE

Interferential Currents

The group with IC received a base frequency of 4000 Hz (Endomed 182, Enraf-nonius, Germany) with an amplitude-modulated frequency (AMF) and slope of 1/1 in tetrapolar mode, as previously indicated. For IC, the same number and type of surface electrodes (5x5 cm Prim-Trode, Spain) were placed onto the anterior and posterior deltoid, supraspinatus fossa and "V" deltoid. Similarly, the intensity of the current was set 3 times per session and the stimulation was strong but comfortable (without exceeding the threshold of pain).
