Exploring Science Behind Muscle Stimulators

From athletes seeking to improve performance to individuals recovering from injuries, the quest to push our bodies and attain muscle strength is universal. But what if it was possible to improve our efforts, speed up recovery, and even access muscle groups neglected by traditional exercises? This is where muscle stimulators come into play, changing the way we look at look at building muscle strength and define physical potential.

Muscle stimulators, once limited to hospitals and elite athletes, are now becoming increasingly accessible to people worldwide. Join us as we delve into the science, benefits, and exciting potential of these stimulators. Also, we look at the parameters of electric muscle stimulation and shed light on the latest developments in muscle stimulation technology. Read on!

What is Electrical Muscle Stimulation (EMS)?

Electrical muscle stimulation (EMS) is a type of electrotherapy that involves the application of electric current to generate a muscle contraction. The electric current is typically applied across the skin’s surface using rubber electrodes or adhesive positioned directly on the skin. The muscle contraction is a result of the electrical current traveling into the tissues and leading to a depolarization of the motor neuron. The muscle contraction using EMS can range from small muscle twitches to powerful contractions that may result in the physiological movement of joints.

The origins of an early form of electrical muscle stimulation go back to the first century. Back then, a Roman physician found that patients having gout experienced a reduction in pain when exposed to an electrical shock. In the early 18th century, physicians made use of devices that delivered electrical shocks for treating several conditions. EMS has evolved throughout the years into advanced muscle stimulators and technology.

Types of Electrical Muscle Stimulation

There are various types of electrical muscle stimulation. The most common forms are explained below:

Transcutaneous Electric Nerve Stimulation (TENS): This EMS type makes use of low-voltage electric currents to relieve pain. TENS uses small, battery-powered muscle stimulators with electrodes to deliver electrical impulses through the skin’s surface. Many healthcare practitioners provide TENS therapy in office and hospital settings. They may also prescribe a TENS unit to use at home. TENS can be used to treat a wide range of conditions, including tendinitis, osteoarthritis, and fibromyalgia.

Neuromuscular Electrical Stimulation (NMES): Also known as electromyostimulation, NMES uses electrical impulses to cause involuntary contractions of muscles. NEMS may be used to help with the proper contraction of muscles after injury or surgery. Also, it can be used to help individuals perform functional tasks. In NEMS, small switches are applied to the body that controls when the stimulation is on or off.

Parameters for Muscle Stimulators

The various parameters for muscle stimulators are given below:

• Frequency: Frequency (Hz) is the number of pulses that pass a certain point in unit time. The frequency for EMS is 20 to 50 pulses per second.
• Pulse Duration: The pulse duration for small muscles is approximately 150 to 200 microseconds, whereas it is 250 to 300 microseconds for large muscles.
• Ramp Time: The ramp time is the duration it takes for a system to attain a steady state from an initial stage. It must be at least 2 seconds for EMS.
• On-off Ratio: The on-off time ratio is set such that the off time is three times the on time.
• Treatment Time: The treatment time for EMS ranges between 20 and 30 seconds.
• Session Frequency: The session frequency is at least three times a week.

Uses of Muscle Stimulators

Physicians use muscle stimulators to help treat pain and help injured, diseased, or weak muscles. They may help with:

• Reversing muscle atrophy and improving muscle strength

• Support of function
• Increase in joint range of motion
• Helps in the proper functioning of cardiovascular devices
• Maintenance of bone density
• Improved local circulation
• Reduction in skin breakdown
• Habilitation

Latest Advancements in Muscle Stimulators

Here are some of the latest developments in the world of electric muscle stimulation:

Improved Technology and Precision: Modern muscle stimulation devices make use of advanced algorithms to offer precise and targeted drug stimulation. That way, healthcare professionals can have more control over the area and depth of muscle activation. Besides, newer models by top industry participants offer a wider range of adjustable settings for effective muscle stimulation. For instance, in May 2024, leading professional pain management company AUVON launched its UVON PT1 Pro TENS Unit Muscle Stimulator. The stimulator comes with multiple customizable modes and intensity levels, providing effective, drug-free, and cost-effective pain relief at home.

Wireless and Wearable Designs: Several top industry players, such as iReliev, Omron Healthcare, and Zynex Medical, have introduced wireless stimulators for improved accessibility and comfort. These wireless units use Bluetooth and other wireless technologies to connect to mobile apps for remote monitoring and control. Besides, advances in wearable technology have led to the introduction of stimulators that can be integrated into clothing or designed to be worn as patches.

Enhanced Safety and User Experience: Modern muscle stimulators come with intuitive features and easy-to-use controls, making them accessible to both consumers and clinicians. Also, improvements in safety mechanisms, such as automation shut-offs and real-time skin response monitoring, help prevent overuse and skin irritation.

Integration with Digital Health Platforms: New stimulators often come with companion apps that track progress and offer real-time feedback. Also, these apps can assist users in adhering to therapy protocols and adjusting settings based on specific needs. Besides, integration with digital health platforms enables better monitoring of treatment efficacy.

Improving Muscle Strength

Muscle stimulators are a new way to enhance the strength, recovery, and rehabilitation of muscles. While they are not a complete replacement for other rehabilitation therapies or dedicated efforts, they represent a powerful way for individuals looking to improve their physical health and well-being. As technology improves and our understanding of the body deepens, we can expect to see the advent of highly advanced muscle stimulators in the upcoming years.
