NMS

NeuroMuscular Stimulation is a type of electro-stimulation unit known by many names in the industry such as e-stim, N.M.E.S., NMS, electrical muscle stimulator, etc. all of these words correspond to a unit providing electro stimulation used for the prevention or retardation of muscle spasm; muscle reeducation; maintaining and increasing the range of motion; increasing local blood circulation or as an immediate post-surgical stimulation of calf muscles to prevent venous thrombosis.

The NeuroMuscular Stimulator (e-stim, N.M.E.S., NMS,) is a form of electro-stimulation that concerns both nerves and muscles. Therefore the stimulators in this electro-stimulation category are used to stimulate the underlying nerves to elicit a muscle contraction.

BioMedical Life Systems, Inc. offers several types of NeuroMuscular Stimulators (N.M.E.S). The EMS 2000   (Electrical Muscle Stimulator) is an analog unit (dials are used to adjust the settings). The unit has 2 channels allowing up to 4 electrodes to be utilized per treatment. This portable unit provides accurate electro stimulation and has a belt clip allowing the patient to wear the unit at home or in the office.

The BioStim® NMS2 is a digital NeuroMuscular Stimulator. The digital technology of this N.M.E.S unit utilizes micro processing to provide accurate electro stimulation. The digital interface allows great flexibility when setting the parameters. It is one of the most powerful portable e-stim units on the market and with 120mA amplitude and a 400 micro second pulse width, this N.M.E.S. unit is ideal for muscle rehabilitation. The BioStim® NMS2 has two waveforms, symmetrical biphasic and asymmetrical biphasic allowing the clinician to choose the type of electro-stimulation they prefer to provide the greatest therapeutic benefit. A timer feature allows for timed treatment and the 8 preset therapies and 3 programmable modes make the unit easy to use without compromising flexibility. The patient lock/compliance monitoring system tracks patient usage while ensuring the settings stay in place as the clinician has prescribed.

The QuadStar II® is in an elite class of digital electrical muscle stimulators. The unit has 4 channels allowing up to 8 electrodes to be utilized per treatment. The QuadStar II® is ideal for the patient who requires muscle rehabilitation in large areas or multiple sites. The unit incorporates a large digital display, 9 preset therapies, three waveforms, asymmetrical biphasic, symmetrical biphasic and pulsed sine, timer, patient lock/compliance system and wall adaptor. This e-stim is ideal for clinic or home use; the unit can stand on a table, or be worn on a belt. The QuadStar II® e-stim can be used for pain relief and muscle rehabilitation. The QuadStar II® is truly in a class of it’s own.
