About this study

Official title: Immediate Effects of Transcutaneous Electrical Nerve Stimulation and High Voltage Pulsed Stimulation on Subacromial Pain and Shoulder Movements

This study was performed to investigate the immediate effects of transcutaneous electrical nerve stimulation (TENS) and high voltage pulsed stimulation (HVPS) on resting pain and pain-free range of shoulder motion (pfROM) in patients with subacromial pain syndrome (SAPS).

Read the detailed description

Transcutaneous electrical stimulation (TENS) and high voltage pulsed current/stimulation (HVPS) are both electrotherapeutic agents which can be used for pain relief in musculoskeletal conditions. Standard TENS devices usually deliver biphasic pulsed currents with a pulse duration between 50 μs and 1000 μs and pulse frequencies between 1 and 250 pps. HVPS devices are TENS-like devices which deliver direct current with twin monophasic spiked pulses of 10-500 V (500-ohm load) with a short pulse duration (microseconds). In both conventional TENS technique and HVPS for pain relief, the aim is to activate spinal gating mechanism by selectively stimulating large diameter Aβ fibers. Theoretically, high-frequency (~10-250 pps), low-intensity (nonpainful) currents are most efficient in selectively activating Aβ fibers, which is practically recognized by the user reporting 'strong but comfortable' nonpainful electrical paresthesia beneath the electrodes. There is no available evidence for the efficacy of TENS in patients with subacromial pain. Also, there has been little experimental work on the effects of HVPS on pain relief in the literature, as well as no known study for its efficacy in SAPS.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change of pain-free shoulder range of motion

    Pain-free ranges of active shoulder flexion, abduction, internal and external rotation were measured by a digital inclinometer (Baseline Digital Inclinometer, 2008 New York-USA), which was calibrated on a flat surface before each measurement. All evaluations were performed before and after each modality application. All of the measurements were performed by a physiotherapist blinded to the modalities applied (placebo/TENS/HVPS).

    Measured: Change of pain-free shoulder range of motions from baseline at the end of 30 minutes of each intervention

Secondary outcomes (1)
  1. Change of pain intensity

    The participants were asked to mark their resting pain intensity on a 0-10 cm visual analogue scale (VAS), where 0 cm indicated no pain and 10 cm indicated unbearable pain. The distance of the marked point from zero point was recorded as the intensity of pain. All evaluations were performed before and after each modality application. All of the measurements were performed by a physiotherapist blinded to the modalities applied (placebo/TENS/HVPS).

    Measured: Change of pain intensity from baseline at the end of 30 minutes of each intervention

Questions about this trial

What is this clinical trial studying?

A study testing Electrical stimulation in people with Shoulder Pain Chronic, run by Mehmet Gürhan KARAKAYA.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change of pain-free shoulder range of motion (time frame: Change of pain-free shoulder range of motions from baseline at the end of 30 minutes of each intervention). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jul 2018.
