Clinical Trial Summary

The purpose of this study is to analyze the effects of an intervention with galvanic electrical current on the number of attacks , temperature, pain, peripheral blow flow and upper limb functionality in patients with Raynaud's Phenomenon in comparison to a control group that will maintain their habitual treatment.


Description:

Raynaud's Phenomenon is a disorder that causes pain and functional limitation in people who suffer it. Investigators considerer that the application of an electrotherapy intervention with galvanic current, thanks to its vasodilator action, will produce clinically significant improvements in the number of attacks, temperature and blood flow of patients with Raynaud's Phenomenon, which can lead to a decrease in pain associated, frequency and severity of ischemic attacks and therefore an improvement in the functionality of the upper limbs. The experimental group will receive an electrotherapy treatment using galvanic current. To apply the treatment, we will place the patient seated, with their hands inside two containers filled with water up to the limit of their nails without touching them. Next we will connect the electrodes and apply a galvanic current for 10 minutes, there will be a minute of rest for the patient while we change the polarity of this current and we will apply it another 10 minutes. The intensity of the current depends on the threshold of the patient. The control group will maintain their usual conservative and pharmacological treatment without receiving electrotherapy

Intervention

Other:
Electrotherapy with Galvanic Current
The experimental group will receive an electrotherapy treatment with galvanic current in their hands.This protocol will be administered at weekly sessions of 30 minutes with a period of 3 times / week with a total of 20 sessions, distributed over a 7-week period. They will be evaluated at baseline, after the end of the last treatment session and after two months of follow-up.
Control without Electric Stimulation Therapy
The control group continue with their usual conservative and pharmacological treatment and will not receive electrotherapy treatment. They will be evaluated too at baseline, after the end of the last treatment session and after two months of follow-up.

Secondary Temperature in the Cold Stress Test Change from temperature in the Cold Stress Test Seven weeks
Secondary Temperature in the Cold Stress Test Change from temperature in the Cold Stress Test Fifteen weeks
Secondary Pain Intensity: Visual Analog Scale Change from baseline in pain in the Visual Analog Scale. Score range between 0-10 cm where 0 is in considerer no pain and 10 is the worst pain imaginable. Seven weeks
Secondary Pain Intensity: Visual Analog Scale Change from baseline in pain in the Visual Analog Scale. Score range between 0-10 cm where 0 is in considerer no pain and 10 is the worst pain imaginable. Fifteen weeks
Secondary Central Sensitization Change from baseline in the Central Sensitization Inventory. The cumulative score ranges from 0 to 100.Higher scores indicate increased frequency and severity of the symptoms. Seven weeks
Secondary Central Sensitization Change from baseline in the Central Sensitization Inventory. The cumulative score ranges from 0 to 100.Higher scores indicate increased frequency and severity of the symptoms. Fifteen weeks
Secondary Pain Catastrophizing Change from baseline in the Pain Catastrophizing Scale. Score range is from 0 to 52; higher scores indicate a greater frequency of catastrophic thoughts. Seven weeks
Secondary Pain Catastrophizing Change from baseline in the Pain Catastrophizing Scale. Score range is from 0 to 52; higher scores indicate a greater frequency of catastrophic thoughts. Fifteen weeks

Secondary Arterial blood flow Change from baseline in Arterial blood flow in the radial and ulnar artery Seven weeks
Secondary Arterial blood flow Change from baseline in Arterial blood flow in the radial and ulnar artery Fifteen weeks
Secondary Upper limb disability Change from baseline in the Disabilities of the Arm, Shoulder and Hand Questionnaire. The score ranges from 0 (no disability) to 100 (most severe disability). Higher scores indicate a greater level of disability and severity. Seven Weeks
Secondary Upper limb disability Change from baseline in the Disabilities of the Arm, Shoulder and Hand Questionnaire. The score ranges from 0 (no disability) to 100 (most severe disability). Higher scores indicate a greater level of disability and severity. Fifteen Weeks
