Electricity has always existed, but humans began harnessing it in the 18th century
Electricity has existed in nature since time immemorial, with humans observing electrical phenomena for more than four millennia. For instance, as early as AD 46, the Roman physician Scribonius Largus recommended that patients stand on live black torpedo fish in shallow water to treat gout and other pains. However, it wasn't until the 18th century and the Enlightenment that humans began to truly understand electricity and harness its power.
In the 18th and early 19th centuries, pioneers in the fields of mathematics, natural philosophy, and experimentation began to unravel the fundamentals of electricity. This led to the development of various medical devices and a better understanding of the relationship between electricity and physiology. One of the earliest applications of electricity in medicine was just three years after the invention of the Leyden jar in 1745, when doctors in Geneva began treating patients with electric shocks.
The recognition of electromagnetism, the unity of electric and magnetic phenomena, is credited to Hans Christian Ørsted and André-Marie Ampère in 1819-1820. Michael Faraday invented the electric motor in 1821, and Joseph Henry demonstrated the practical applications of electricity in 1829 by using a large battery to build a powerful electromagnet capable of lifting hundreds of pounds of metal.
The invention of the incandescent lightbulb in the 1870s marked one of the first publicly available applications of electrical power, revolutionizing lighting in homes and factories and reducing fire hazards. The electrical telegraph, demonstrated commercially in 1837, was another early application of electricity, enabling global communications in minutes with the construction of transcontinental and transatlantic telegraph systems in the 1860s.
By the turn of the 20th century, electricity had become integral to medicine, with more than 90% of physicians' offices in large US cities having electrical treatment devices. The development of the pacemaker, for instance, was a result of experiments with electricity, and it led to further inventions to stimulate muscles and cure ailments.

The first recorded treatment of a patient with electricity was in 1743
The use of electricity in medicine has a long history, dating back more than 2000 years. As early as AD 46, the Roman physician Scribonius Largus documented the use of standing on live black torpedo fish in shallow water as a treatment for gout and other types of pain. This method, recommended by Largus in his Compositiones Medicae, was also advocated by Claudius Galen, a physician who lived from 131-201 AD. Galen's word carried significant weight in medical circles for several millennia, and his endorsement of using electric fish for therapeutic purposes held sway for many centuries.
It wasn't until the 1700s that electricity was independently harnessed and employed in medical devices, marking a pivotal shift in the understanding and utilisation of electricity in medicine. The first recorded treatment of a patient with electricity was in 1743, and the exploration of electricity's medical applications gathered momentum in the 18th and early 19th centuries. In 1745, just two years after that inaugural treatment, doctors in Geneva embarked on a course of treatment for patients involving electric shocks. This approach was based on the belief that paralysis could potentially be cured by subjecting the muscles to repeated shocks.
The pioneering work of Luigi Galvani, who discovered "animal electricity" and unravelled the role of electricity in neuron signalling to muscles, further emboldened doctors to delve deeper into the therapeutic possibilities of electricity. Guillaume-Benjamin Duchenne, hailed as the "father of electrotherapy," was a staunch proponent of utilising electric shocks as a potential cure for various ailments. He also made significant contributions to the development of the pacemaker, employing electrical currents to induce electrophrenic stimulation in the resuscitation of a drowned girl.
The late 19th century witnessed a surge in the exploration of electricity's medical applications. In 1894, German physicist Wilhelm Conrad Roentgen began experimenting with vacuum tube equipment, leading to the discovery and documentation of X-rays. This breakthrough allowed for the visualisation of underlying structures, such as bones, revolutionising medical imaging. The electrical telegraph, commercially demonstrated in 1837, facilitated rapid global communication, paving the way for electricity's integral role in telecommunications.
The early 20th century saw electricity firmly established as a medical tool, with over 90% of physicians' offices in major U.S. cities like New York City equipped with electrical treatment devices. Researchers in Europe during this period also explored the potential of electricity in anaesthesia, attempting to induce unconsciousness through various electrical stimuli. Electricity's versatility and adaptability across a range of medical applications, from imaging and communication to treatment and resuscitation, underscore its enduring significance in shaping the landscape of modern medicine.

Ancient Egyptians and Romans used the electric torpedo fish medicinally
The history of electricity is a long and fascinating one, with the phenomenon finding its way into various applications that have shaped our world today. One of the earliest recorded uses of electricity in medicine dates back to ancient Egypt and Rome, where the electric torpedo fish was a key component.
Ancient Egyptians and Romans' Use of the Electric Torpedo Fish Medicinally
The electric torpedo fish, or *Malapterurus electricus*, has been recognised for its medicinal properties since ancient times. The first known depiction of this electric catfish was discovered in the tomb of the architect Ti in Saqqara, Egypt, dating back to 2750 BC. This ancient mural illustrates a man in a small boat about to experience a shock from a Nile catfish.
The Ancient Egyptians were aware of the electric catfish's ability to generate shocks and put it to use for medical purposes. Papyri records from ancient Egypt, dating back 4700 years, mention the use of the electric fish to relieve pain. Similarly, the Romans also recognised the medicinal value of the torpedo fish. Murals discovered in Pompeii, dating 3000 years after the Saqqara mural, depict similar scenes.
The electric torpedo fish was prescribed by ancient physicians such as Hippocrates, Scribonius Largus, and Galen for various ailments. Galen, a Greek physician and surgeon in the Roman Empire, even experimented on himself with the torpedo fish to confirm its efficacy. The treatments included applying the fish to the forehead to alleviate headaches, treating gout, and reducing prolapsed anus. Additionally, parts of the torpedo fish's body, especially the liver, were used to prepare potions and ointments believed to have curative and anti-aphrodisiac properties.
The use of the electric torpedo fish in medicine continued to evolve over the centuries, with the advent of electrotherapy in the 18th century. The ancient electro-therapeutic remedies were practised globally until at least the 18th century, with the electric battery and other devices becoming panaceas for various ailments. While some legitimate medical uses of electrotherapy included treating headaches, cauterising wounds, and stimulating paralysed muscles, charlatans also utilised electric devices, promising cures for all diseases.

Electrotherapy is used to speed up wound healing
The use of electricity has evolved over the years, from early experiments with electric eels in ancient Greece and Rome to the invention of the Leyden jar in 1745. Just two years later, in 1747, doctors in Geneva began treating patients with electric shocks, marking the beginning of electrotherapy.
Electrotherapy, or electrical stimulation (ES), has been used in recent times to speed up wound healing. This technique has been shown to be safe, effective, and well-tolerated by patients. It has been used to treat various types of wounds, including acute wounds, chronic wounds, diabetic ulcers, pressure ulcers, and foot ulcers. ES has been found to increase epithelialization, fibroblast migration, and vascularity around wounds, leading to faster wound area reduction and improved healing rates.
Electrotherapy can be combined with advanced technologies such as active dressings, 3D printing, scaffold, drug delivery, or smart skin to enhance its therapeutic effects on wound healing and skin regeneration. Additionally, the use of a magnetic field in electrotherapy has been reported to have beneficial effects on pain management, bone fracture healing, and wound healing.
While electrotherapy has demonstrated promising results in wound healing, it is not yet widely adopted in regular practice. The NICE guidelines in the UK, for example, do not recommend using ES therapy on chronic wounds outside of clinical trials. However, physicians in Australia, New Zealand, and the United States are recommended to use ES as an adjunct therapy for treating chronic pressure ulcers.
Overall, electrotherapy has shown potential in accelerating wound healing, and further research and clinical trials are being conducted to explore its full potential and effectiveness in different types of wounds.
