Frequently Asked Questions

  • When BIOSTIM SPT® therapy indicated?

    If, after trauma a fracture does not show progression towards healing after more than 3 months, BIOSTIM SPT® therapy can be adopted to trigger osteogenesis and to finalise the repair process. 

  • How does BIOSTIM SPT® therapy work?

    BIOSTIM SPT® therapy delivers a pulsed electromagnetic fields that induces at the fracture site an electric field that triggers bone healing.

    The treatment efficacy depends on the physical parameters of the electromagnetic signal: 75 Hz, 1.3 ms pulse duration, 2 mT magnetic field.

    In summary, BIOSTIM SPT® therapy biophysical signal acts on the cell membrane favouring the release of calcium ions from the endoplasmic reticulum.

    The localised increase in calcium triggers the bone repair process.

  • How to know if BIOSTIM SPT® therapy is working properly?

    The device is switched on by placing the button in position "I" (ON) and BIOSTIM SPT® therapy commences normal operation.

    A green light will illuminate to indicate that the generator is on and powered and, at the same time a second green light will illuminate indicating the presence of the solenoid driving signal.

    Once the therapy is over, deactive the device by putting the switch in the "O" position (OFF) and disconnect the power supply from the socket.

  • Is BIOSTIM SPT® therapy safe?


    Its biological and electrical safety are widely documented.

    Thousands of patients have successfully used BIOSTIM SPT® therapy in the absence of negative side effects.

    BIOSTIM SPT® therapy is manufactured in compliance with the IEC 60601-1 standards, meets the requirements of directive 93/42/EEC and it is CE0051 marked.

  • How long does daily treatment last?

    BIOSTIM SPT® therapy recommended daily treatment regime consists of 8 hours per day preferably during the night (the treatment can be split in 4 sessions of 2 hours). 

    The attending physician will specify the total duration of the therapy in accordance to the pathology being treated.

  • How long does healing take with BIOSTIM® therapy?

    Treatment length depends on the severity of and length time since fracture.

    The doctor prescribes the therapy based on his experience and on the results of clinical trials.

    Before discontinuing therapy, even if there are clear signs of improvement, it is always necessary to firstly consult your doctor.

    The constant daily use of BIOSTIM SPT® therapy and the continuity of treatment until recovery is essential to promote the healing process.

  • Does BIOSTIM SPT® therapy need special care or specific maintenance?


    BIOSTIM SPT® therapy is prepared and shipped to patients ready for use. No intervention or maintenance is required.


    To guarantee the reliability of performance, BIOSTIM SPT® therapy should be subjected to ordinary maintenance procedures and a control of the operating parameters (to be performed by the IGEA Service Centre) every 24 months of use (Guide IEC 62-122).
