What SIS can—and cannot—do
The Super Inductive System (SIS) is a non-invasive electromagnetic therapy that can produce involuntary muscle contractions. It may be considered as an adjunct when weakness, reduced activation, or selected pain and stiffness make active rehabilitation difficult; it is not a replacement for diagnosis, exercise therapy, fracture care, or specialist treatment.
The device applies a changing magnetic field over a selected body region. The induced electrical currents can stimulate peripheral nerves and muscles, but the clinical response varies and depends on the diagnosis, settings, tissue, and concurrent rehabilitation. A device specification or field strength does not prove that treatment will heal a fracture, reverse spasticity, or provide lasting pain relief.
Rehabilitation goals that may be considered
Is SIS electromagnetic therapy right for you?
A possible adjunct—not a shortcut
SIS may be discussed when an examination identifies a suitable rehabilitation goal and there is no safety contraindication. It cannot be promised to accelerate recovery, replace strengthening, or treat an undiagnosed pain, fracture, or neurological condition.
Ideal indications
You have a documented rehabilitation problem involving weakness or poor muscle activation.
You can participate in active exercise, or have a graded plan for doing so after treatment.
Your clinician has reviewed your diagnosis, medications, implanted devices, and treatment goals.
You understand that response may be temporary or absent and that multiple sessions may not help.
Clinical precautions
You have a pacemaker, implanted defibrillator, neurostimulator, cochlear implant, insulin pump, or another active electronic implant unless the device manufacturer and clinician specifically clear it.
You have metal, medication pumps, or other hardware near the treatment area whose compatibility is uncertain.
You are pregnant, have an acute unexplained illness, active infection, recent fracture, seizure disorder, or another condition requiring clinician review before stimulation.
You develop severe pain, dizziness, weakness, palpitations, skin changes, or other concerning symptoms during treatment—stop and seek urgent medical assessment.
Super Inductive System (SIS) Realities
Understanding the sensations of high-intensity electromagnetic therapy.
Intense Muscle Contractions
The field can cause involuntary contractions, tingling, fatigue, or discomfort. Intensity should be adjusted to tolerance, and treatment should stop if symptoms are concerning.
Temporary Autonomic Responses
Temporary fatigue, muscle soreness, or autonomic symptoms can occur. Report persistent or severe symptoms rather than assuming they are a normal response.
Hardware Contraindications
Compatibility depends on the specific device, implant, location, and manufacturer guidance. Bring implant details so the clinician can screen you before treatment.
Why Standard Therapy Tools Fall Short
Standard TENS
Electrical stimulation through skin electrodes may help selected pain or muscle-activation goals, but its effects and depth differ from SIS.
Super Inductive System (SIS)
Can produce magnetic stimulation and involuntary contractions without skin electrodes. It still requires diagnosis, safety screening, and active rehabilitation; outcomes vary.
Manual Physical Therapy
Assessment, education, exercise, pacing, and hands-on care can address the underlying functional problem and remain central to rehabilitation.
The Fast-Track to Mobility
After the session
Some people notice temporary changes in muscle activation, discomfort, or pain; others notice little change. Do not drive or exercise beyond your plan if the treated area feels weak or fatigued.
Progressive rehabilitation
If SIS is continued, the clinician reviews function, symptoms, and adverse effects rather than assuming a fixed session schedule or automatic muscle growth.
Reassessment
Treatment is continued only when there is a reasonable goal and observed benefit. Persistent weakness, severe pain, neurological change, or delayed fracture healing needs diagnosis and escalation.
Clinical Science & Technical Details
For our medical colleagues and highly analytical patients, we provide these transparent technical details on the pathophysiology and interventional protocols.
Explore the Clinical Science: Action Potentials and Osteogenesis
SIS uses a changing magnetic field to induce electrical currents in tissue and can stimulate peripheral nerves and muscles. The exact effect depends on the device settings, location, tissue, and diagnosis; a proposed mechanism is not proof of a clinically meaningful outcome.
Evidence for electromagnetic stimulation differs by indication and device. It should not be presented as rapidly healing a fracture or as a substitute for fracture alignment, immobilisation, imaging, or orthopaedic follow-up.
Detailed Diagnostic Pathways: Managing Neurological Spasticity
For post-stroke spasticity, SIS offers a neuro-modulatory approach. By applying specific frequencies over antagonist muscle groups, we induce reciprocal inhibition.
Stimulation may be explored as one part of post-stroke rehabilitation, but it does not reliably ‘fatigue’ or reset spinal circuits. Spasticity needs neurological assessment, goal-directed therapy, and escalation when there is new or worsening weakness, swallowing difficulty, speech change, or loss of function.
Advanced Systemic Screening: Ferromagnetic Contraindications
SIS screening is not automatically identical to MRI screening. Active electronic implants and some metal or medication-delivery devices may be contraindications or require manufacturer-specific clearance.
Remove external metal and electronic items as instructed. Do not infer safety from a label such as ‘titanium’; the implant’s location, design, and the device instructions still matter.
Managing Tetanic Contractions and Lactic Acid Clearance
SIS can produce strong or repeated involuntary contractions, but the response is not equivalent to a maximal workout or rapid muscle growth. Soreness and fatigue are possible, so the dose should be progressed cautiously.
Claims that a ‘washout’ phase flushes lactic acid or prevents delayed soreness are too strong. Recovery should rely on symptom monitoring, hydration and usual rehabilitation guidance rather than a promised physiological reset.
Inside the Procedure: Frequency Modulation for Callus Formation
Bone-stimulation research is indication- and device-specific. A fracture that is not healing needs imaging and orthopaedic assessment; stimulation cannot replace alignment, stability, infection assessment, or surgical review.
Do not use SIS to promise rapid callus formation. If a clinician considers an electromagnetic bone-stimulation approach, the expected benefit, alternatives, time course, and follow-up imaging should be explained.
Neuroplasticity and Long-Term Motor Relearning
In stroke rehabilitation, sensory and motor practice can support task-specific learning, but no device can be said to force the brain to rewire or build pathways around damaged tissue. SIS, if selected, should complement repetition, strengthening, balance work, and functional goals.
New stroke symptoms—facial droop, arm weakness, speech or vision change, severe headache, or loss of balance—are emergencies, not indications for a therapy session.
The Contactless Healing Session
Fully Clothed Positioning
You remain clothed as appropriate, remove items requested during screening, and are positioned so the applicator can be placed over the selected region.
The Magnetic Contraction
You may hear pulsing and feel involuntary contractions or tingling. The clinician adjusts the intensity and duration to the treatment goal and your tolerance.
Immediate Functional Integration
If appropriate, the session is followed by active movement or exercise so any temporary change is linked to a functional rehabilitation goal.
Clinical decision support
The evidence for high-intensity magnetic stimulation is still developing
Super Inductive System treatment is a form of high-intensity peripheral magnetic stimulation. Research across musculoskeletal and neurologic uses is heterogeneous, with different devices, doses, comparators, and outcomes. Recent reviews describe possible benefits for selected symptoms or function but rate much of the evidence low or very low certainty. It should therefore be framed as an adjunctive trial, not a proven cure, nerve regeneration treatment, or replacement for established rehabilitation.
Candidacy requires device-specific screening. Implanted electronic devices, metal near the treatment field, pregnancy, seizure history, impaired sensation, active cancer, or other medical factors may be relevant. The treatment should have a defined target and stop rule so a lack of meaningful functional change does not lead to open-ended sessions.
