Based on (i) equivalence of the intended use, (ii) method of application in the body, (iii) similar patient
population, and (iv) critical performance necessary to achieve the expected clinical effect, the clinical
characteristic of the NeuroMove 900 device is equivalent to the predicate AutoMove 800 device.
Technical equivalence
The NeuroMove 900 has the same or similar technical characteristic as other referenced emg‐triggered
muscle stimulation devices.
The key aspects of the NeuroMove 900 design are also found in the equivalent devices. All of the emg‐
triggered stimulation devices work by attaching non‐invasive electrode pads over the muscle and setting
a stimulation level
(mA) to see visible movement of the muscle and feel the stimulation. The specific
geometry of the NM 900 device is comparable to all of the predicate devices.
Based on similarities in the basic design features, geometry, size, shape, materials and strength, and the
conditions of use, the technical characteristics of the NM 900device are substa
ntially similar to the
predicate devices.
Also, mechanical testing demonstrates comparable mechanical properties to predicate devices. Thus,
the NeuroMove 900 device is substantially equivalent to predicate devices.
Assessment of clinical data
Based on the critical evaluation of the literature, there is a substantial body of evidence to support
efficacy of equivalent devices for the indications and type of applications claimed for emg‐triggered
electrical stimulation, evidence supports efficacy of emg‐triggered electrical stimulation for stroke,
spinal cord injury, traumatic brain injury, increased movement, in
creased hand/wrist movement,
increased dorsiflexion, increased elbow movement, increased shoulder movement and to decrease
muscle spasms.
Overall, there is a support for favorable benefit for the NeuroMove 900 device based on the review
overview of clinical outcomes for equivalent devices.

• CHRONIC MOTOR DYSFUNCTION
Stroke is the number one cause of functional disability in this country with approximately 795,000
strokes occurring annually. Voluntary movement control is typically impaired after a stroke. The specific
neurological mechanisms that mediate neuromuscular recovery are still not understood. Evidence
suggests that some motor recovery occurs because the auxiliary cortex areas may take over some
functions.
