4.2.2 NMES
Neuromuscular Electrical Stimulation (NMES) is an electrical stimulation training
mode. NMES provides an electrical impulse through surface electrodes to the
peripheral nerves to evoke an action potential. Repeated assisted contractions
of a weak, dysfunctional neuromuscular system results in stronger, more efficient
and coordinated muscle movement. The iPad APP has 4 fixed prescriptions and
1 customized prescription (Custom settings by medical professionals according
to patients' actual conditions) for different body parts based on international
common standards of electrical stimulation and our company's independent study.
sEMG TEST
The sEMG test in the APP detects the patient's EMG signal and provides a sum
of the activity measured in microvolts and a display of the results. This objective
data can be used to establish baseline and progress over time. The threshold is
set in “Setting” by comparing the test results.
After setting, the threshold will be recorded by the system. If user doesn't set
threshold, the system will work with the previously set threshold.
Swallowing sEMG TEST
The swallowing sEMG test detects the EMG signal during a swallow and provi-
des a visual display of the average microvolts. sEMG for swallowing is very
different than sEMG for other muscle movements as the reliability of the signal
will be directly impacted by the type of swallow elicited such as; dry swallow,
5cc water, 10cc water, puree or solid bolus. Proper use of sEMG can be very
useful in providing objective data for establishing baseline and progress over
time. Improper use of sEMG will not yield useful or accurate data.
The stimulator has 5 prescriptions as follows:
4 fixed prescriptions and 1 customized which can either be downloaded from
the APP or manually set through the stimulator.
The following are the 4 fixed prescriptions, each one lasts about 30 minutes:
After selecting a prescription, press to start training.
The initial current is 0 mA for security. User can press or to adjust the
intensity.
Proper use of NMES requires that the stimulus is modified and manipulated
according to the patient's individual needs, the 4 prescriptions provided may
work for the majority of patients but in many cases the stimulus must be
customized for an optimal response. A custom prescription can be created
by connecting the stimulator to iPad, clicking on the 5th prescription and
entering the parameters needed.

user can increase to the appropriate current level and start the training
