With voluntary muscle action progressively affected, patients in the later stages of the disease may become totally paralyzed.
With voluntary muscle action progressively affected, people may lose the ability to speak, eat, move and breathe.
When we move freely
with our voluntary muscles, in non-compulsive exercise, we stimulate our smooth muscles to also move internally.

Now, in this follow - up study, Claudia Angeli, Ph.D., assistant professor at the University of Louisville's Kentucky Spinal Cord Injury Research Center and her research colleagues report that three additional patients
with paralysis have recovered
voluntary muscle control following electrical stimulation of the spine.
The study of electricity in
muscles probably began as early as the middle of the 1600s,
with the discovery of the electric ray fish and experiments using frog legs (Clarys, 1994; Reaz et al. 2006), although it was not until 1792 that it was discovered that electricity could actually produce
muscle contractions (Reaz et al. 2006), and 1849, when it was found that electric potential difference (also known as voltage) could be monitored in
voluntary muscle actions (Reaz et al. 2006).
After ROM measurements, the subjects were familiarized
with the myofascial foam rolling technique, performed the maximum
voluntary contraction (MVC)
with the interpolated twitch technique (ITT), and received a 100 - Hz tetanic
muscle stimulation.
An interpolated twitch ratio was calculated comparing the amplitude of the interpolated twitch
with the potentiated twitch to estimate the extent of inactivation during a
voluntary contraction (interpolated doublet force / potentiated doublet force × 100 = percent of
muscle inactivation)(10).
They report that the pronated grip pull up produced comparable (120 % vs. 117 % of maximum
voluntary isometric contraction (MVIC) levels) latissimus dorsi
muscle activity compared
with the supinated chin - up exercise.
They reported that the inverted row performed
with a supinated grip produced superior (94 % vs. 79 % of maximum
voluntary isometric contraction (MVIC) levels) latissimus dorsi
muscle activity compared to the pronated grip inverted row variation.
