Frequency-specific microcurrent improves hand function and Raynaud's symptoms in scleroderma: results of two pilot...

Area of Science:

• Rheumatology
• Physical Medicine and Rehabilitation

Background:

• Systemic sclerosis (SSc) frequently causes significant hand dysfunction and Raynaud's phenomenon.
• Current treatments for SSc-related hand issues have limitations, necessitating novel therapeutic approaches.

Purpose of the Study:

• To assess the efficacy of frequency-specific microcurrent (FSM) in improving hand function and alleviating Raynaud's symptoms in SSc patients.
• To evaluate FSM as a potential non-invasive treatment modality for SSc complications.

Main Methods:

• Two pilot studies involving 17 SSc patients treated with FSM targeting scarring and capillaries.
• Treatment durations varied from 45 to 60 minutes over 1-2 days.
• Efficacy was measured using the Cochin hand function score and a visual analogue scale (VAS) for Raynaud's severity.

Main Results:

• Significant improvements in hand function were observed, with a combined average increase of 40% (P < 0.0001).
• Mean Raynaud's VAS scores improved significantly by 18 points (P = 0.016).
• Some patients experienced substantial functional gains, transitioning from severe difficulty to ease in performing tasks.

Conclusions:

• Frequency-specific microcurrent therapy demonstrated significant efficacy in improving hand function and reducing Raynaud's symptoms in SSc patients over a short treatment period.
• Further randomized controlled trials are necessary to validate these findings and assess long-term outcomes and treatment sustainability.
