In Voltron, Takashi Shiro Shirogane is a tall human male with a Herculean physique, broad face, strong jaw, and dark hair. Shiro has a prosthetic right arm, two gold stripes identifying him as a junior officer, and an armband that tracks the progress of his muscle condition. This armband is an electro-stimulator for his muscles, which he brushes off as something that happens when you're an old timer. Shiro's illness is speculated to be Becker Muscular Dystrophy, a disease that affects muscle growth and strength. This speculation is supported by the fact that Shiro says he will only be in peak physical condition for a couple more years, implying that he has a degenerative physical condition.

What You'll Learn
To track the progress of his muscle condition
Shiro, the taller-than-average male with a Herculean physique, broad face, strong jaw, and dark hair, has an electro-stimulator for his muscles. This is because he suffers from a chronic illness that affects his muscles. It is believed that he has Becker Muscular Dystrophy, a disease that affects muscle growth and strength. The illness usually shows symptoms around late childhood to early adolescence, and it causes the muscles to grow weaker over time.
Shiro's electro-stimulator is an armband that tracks the progress of his muscle condition. It is a rehabilitation technology that can restore some degree of motor function. This technology is often used by individuals who have sustained a spinal cord injury or stroke. It works by using electromyographic (EMG) activity recorded from able-bodied subjects as a template for electrical stimulation. This template is then converted into an appropriate pattern of electrical stimulation through a transfer function.
The armband that Shiro wears is likely tracking the progress of his muscle condition by recording the EMG activity of his muscles and then stimulating them to improve their strength and growth. This would help him to manage his chronic illness and maintain his physical condition. The electro-stimulator is an important tool for Shiro to maintain his health and ensure that his illness does not progress too rapidly.

To prevent atrophy and weakness
In Voltron, Shiro has an armband that tracks the progress of his muscle condition. He has an electro-stimulator for his muscles, which he brushes off as "what happens when you're an old-timer".
Shiro's electro-stimulator could be used to prevent atrophy and weakness in his muscles. Aging and inactivity cause atrophy and weakness in the muscles, leading to a loss of the heart-assisting role. An electrical lower limb muscle stimulator can prevent atrophy and weakness more effectively than conventional resistance training.
Functional electrical stimulation is a rehabilitation technology that can restore some degree of motor function in individuals who have sustained a spinal cord injury or stroke. One way to identify the spatio-temporal patterns of muscle stimulation needed to elicit complex upper limb movements is to use electromyographic (EMG) activity recorded from able-bodied subjects as a template for electrical stimulation. This requires a transfer function to convert the recorded (or predicted) EMG signals into an appropriate pattern of electrical stimulation.
Cardiac cycle-synchronized electrical muscle stimulation is a newly developed technology that combines a commercially available electrocardiogram monitor and a belt electrode skeletal muscle electrical stimulator. This technology can achieve strong and wide but not painful muscle contractions. This technology has been tested on healthy volunteers to determine whether it enables lower limb muscle training without harming hemodynamics. The results showed that the stimulator generated diastolic augmentation waves and end-diastolic pressure reduction waves, demonstrating its potential to reduce the heart's pumping workload.

To restore motor function
Shiro's electro-stimulator is likely used to restore motor function and prevent muscle atrophy and weakness. This is particularly important given Shiro's illness, which affects his muscles and causes them to grow weaker over time.
Functional electrical stimulation (FES) is a rehabilitation technology that can restore motor function in individuals who have sustained a spinal cord injury or stroke. FES uses electromyographic (EMG) activity recorded from able-bodied subjects as a template for electrical stimulation. This requires a transfer function to convert the recorded EMG signals into an appropriate pattern of electrical stimulation, which can then be used to modulate muscle output by varying the pulse frequency and amplitude.
In addition to restoring motor function, FES has been shown to be an effective method for preventing muscle atrophy and weakness, particularly in inactive patients. This is achieved by intentionally contracting a muscle through electrical stimulation, which can also be used to supply power to implantable medical devices such as pacemakers and neurostimulators.
The use of FES has been found to be advantageous over conventional resistance training in preventing atrophy and weakness of the lower limb muscles, which play an important role in decreasing the heart's pumping workload. By developing a cardiac cycle-synchronized electrical lower limb muscle stimulator, researchers have been able to achieve strong and wide muscle contractions without causing pain. This technology combines a commercially available electrocardiogram monitor and a belt electrode skeletal muscle electrical stimulator, which has been shown to be effective in reducing the heart's pumping workload.
Overall, the use of an electro-stimulator can be an effective tool for restoring motor function and preventing muscle atrophy, which is crucial for managing Shiro's muscle-degenerative illness.

To reduce the heart's pumping workload
In Voltron, Shiro has an electro-stimulator for his muscles. It is a band that he wears on his arm. This is likely due to the character's illness, which is thought to be Becker Muscular Dystrophy, a disease that affects muscle growth and strength. The illness causes muscles to grow weaker over time, and it affects the muscles in the hips, pelvis, thighs, shoulders, and arms.
Functional electrical stimulation is a rehabilitation technology that can restore some degree of motor function in individuals who have sustained a spinal cord injury or stroke. It can also be used to prevent muscle atrophy and weakness for inactive patients. Electrical muscle stimulation (EMS) contracts skeletal muscles via percutaneous electrodes that depolarize underlying motor nerves.
EMS has been reported to increase the heart's pumping workload in some situations. However, there is also a report that suggests that EMS to the lower limbs decreases the vascular resistance when the muscle contraction is generated in a cardiac recovery phase. This indicates that EMS therapy may be safe and desirable for patients with heart failure if it is controlled based on cardiac cycle information to reduce the heart's pumping workload.
A cardiac cycle-synchronized electrical lower limb muscle stimulator has been developed by combining a commercially available electrocardiogram monitor and a belt electrode skeletal muscle electrical stimulator. This stimulator achieves strong and wide but not painful muscle contractions. Testing the stimulator on 11 healthy volunteers showed that it generated diastolic augmentation waves and end-diastolic pressure reduction waves, indicating that it may be possible to achieve lower limb muscle training without harming hemodynamics.

To relieve symptoms of PTSD
Shiro's experiences as a gladiator and a test subject have left him suffering from Post-Traumatic Stress Disorder (PTSD). He has momentary flashbacks when confronted with particular stimuli, which are actually invasive memories triggered by things that are connected to or similar to his traumatic experiences.
To relieve the symptoms of PTSD, Shiro could benefit from rehabilitation technologies such as functional electrical stimulation (FES). FES can help restore motor function in individuals with spinal cord injuries or strokes. It works by using electromyographic (EMG) activity recorded from able-bodied subjects as a template for electrical stimulation. This can help to elicit complex upper limb movements and improve motor function.
Additionally, electrical muscle stimulation (EMS) can be used to prevent muscle atrophy and weakness, which is a common symptom of aging and inactivity. EMS contracts skeletal muscles via percutaneous electrodes, depolarizing the underlying motor nerves. This form of stimulation can be particularly effective for outpatients as it is simple and passive, allowing for long-term use.
Furthermore, cardiac cycle-synchronized electrical muscle stimulators can be used to reduce the heart's pumping workload. This technology combines a commercially available electrocardiogram monitor with a belt electrode skeletal muscle electrical stimulator, resulting in strong and wide but painless muscle contractions. This method has been shown to increase heart rate, stroke volume, and cardiac output during stimulation.
By utilizing these electrical stimulation techniques, Shiro may be able to alleviate some of the physical symptoms associated with his condition, such as muscle weakness and atrophy, while also potentially improving his overall cardiac health.
