ABSTRACT
OBJECTIVE:
To analyze the effectiveness of an electrotherapy intervention with galvanic current on symptoms associated with Raynaud's phenomenon.DESIGN:
Single-blind randomized controlled trial, parallel design (11 ratio) and intention-to-treat analysis.SETTING:
Virgen de las Nieves Hospital, Granada, Spain.SUBJECTS:
Thirty-four participants with Raynaud's phenomenon, with a mean (SD) age of 43.43 (17.62) years.INTERVENTIONS:
The patients were randomly assigned to a control group with conservative treatment (anti-inflammatory, vasodilatory and analgesic drugs) or an intervention group that received conservative treatment and vasodilatory electrical stimulation during seven weeks, three times/week for a total of 20 sessions. MAINMEASURES:
The primary outcome was the number of attacks. Secondary outcomes were pain, peripheral blow flow, oxygen saturation, upper limb disability, central sensitization, pain catastrophizing and temperature recovery. All outcomes were assessed at baseline, posttreatment and at two months of follow-up.RESULTS:
The galvanic current electrotherapy group showed significantly greater improvements in the number of attacks (mean difference = 26.3, 95% confidence interval (CI) = 14.4 to 38.3), pre-cold stress pain (95% CI = 0.6 to 2.4), radial artery blood flow (95% CI = -7.8 ⩾ x ⩽ 1.3), ulnar artery blood flow (95% CI = -8.63 to 0.60), oxygen saturation (95% CI = -1.7 ⩾ x ⩽ -0.29), upper limb disability (95% CI = 1.1 to 22.3), central sensitization (95% CI = 6.7 to 18.2) and temperature recovery (95% CI = -5.7 ⩾ x ⩽ -0.32) than the conservative treatment group.CONCLUSION:
This study suggests that a complementary treatment with galvanic current in combination to conservative approach is superior to conservative applied as isolate, in reducing the clinical manifestations and disability in Raynaud's phenomenon.Key words
