Sondra Microcurrent Point Stimulation (MPS) is a non-invasive, needle-free therapy that combines acupuncture principles with low-frequency direct current (DC) to treat chronic pain, scars, and stress. Both MPS and electroacupuncture stimulate acupuncture points to relieve pain and balance the nervous system by targeting acupuncture/trigger points to release endorphins. The key difference is that MPS is non-invasive (uses a probe rather than needles) and uses low-intensity direct current, whereas traditional electroacupuncture often uses needles with higher intensity alternating current.
MPS uses a handheld probe for direct, non-invasive stimulation of acupuncture points. Electroacupuncture involves attaching electrodes to needles inserted into the skin. MPS uses microcurrents (measured in milliampere), which are sub-sensory and mimic the body’s natural electrical frequency. Electroacupuncture uses much stronger milliamperage. Both target meridians and nerve points, but MPS is specialized for scar release therapy and relaxing chronic muscle contraction (guarding). MPS is generally painless, making it ideal for patients sensitive to stronger currents.
MPS uses a handheld device (such as the Dolphin Neuro-stim) to apply gentle, low-frequency DC microcurrents to the skin, which is often considered more comfortable and less invasive. Both therapies focus on stimulating trigger points and nervous system regulation to manage pain, but MPS is specifically noted for its focus on softening scar tissue and calming the nervous system.
Differences between MPS and traditional electroacupuncture.
Methodology. MPS uses handheld metal probes to stimulate points. Electroacupuncture uses needles inserted into the skin.
Sensation. MPS is typically sub-sensory (non-invasive, painless). Electroacupuncture may produce a pulsating sensation.
Intensity. MPS uses very low-level (microampere) current that mimics the body’s natural electrical flow. Electroacupuncture generally uses higher, milliampere levels of current.
MPS is often described as a hybrid of acupuncture and microcurrent therapy, sometimes referred to as “non-needling electro-acupuncture.” According to Acupuncture Today, in their article The Magic of Microcurrent, microcurrent therapies reduce electrical resistance on the body areas and pathways to improve healing.
Elio, et al. (2014), studied how microcurrent affected lymphedema and found that the volume of the limb measured had a 2% reduction after six days of treatment. The pre/post-treatment visual analog scale score changes were a 47% reduction in heaviness and a 64% reduction in pain, with no side effects reported.
Conclusions: The preliminary data of this pilot study show that the combination of microcurrents of bioresonance with transdermal delivery of active principles indicate that it could result in edema decrease and symptom improvement in patients affected by LYM and/or LIP of the lower limbs. Self-administered modality of the electrical device is possible and effective; no side effects have been reported.

About Magnesium Silicate
Magnesium silicate has been studied as a transdermal (skin-delivered) agent combined with specialized electromedical devices to treat lower limb lymphedema and lipedema. It is used to help improve lymphatic drainage and reduce limb volume, particularly when combined with microcurrents or vacuum technologies.
Magnesium silicate is delivered transcutaneously (through the skin) during sessions that use microcurrent to potentially lyse protein aggregates and enhance lymphatic drainage. Studies have shown that this approach can lead to improvements in lymphedema, including reducing limb volume (e.g., studies reported an 8% reduction in lower leg volume) and improving lymph node visualization on imaging — in a pilot study, magnesium silicate was applied during daily sessions, which were initially done by a physiotherapist and later self-administered by patients at home. The treatment has been reported to be safe with no significant side effects highlighted.
Beyond direct treatment, hydrous magnesium silicate (talc) is used in herbal poultices and compresses to support the skin, acting as a moisture-absorbing agent that keeps the area dry and comfortable. Magnesium silicate is also known as a component of talc, and the material used in these therapeutic contexts is generally recognized as safe (asbestos-free). According to Drugs.com, talcum products used in cosmetics have been free of asbestos since the 1970s. Magnesium silicate should not be confused with systemic magnesium supplements, which work differently on fluid regulation.
