G-TES in use.

Exercise substitution devices that make previously impossible exercises possible.

The G-TES®* is designed around the B-SES* therapeutic approach, utilizing belt electrodes to stimulate various muscles. This enables both strength and aerobic exercises to be customized to individual goals, ensuring exercises are performed safely and effectively.

By encircling the waist, knees, and ankles with belt electrodes and delivering electrical stimulation tube-like, G-TES® can mimic a range of voluntary muscle movements.

Aging, a sedentary lifestyle, orthopedic conditions, and respiratory or circulatory issues can weaken the muscles. This not only exacerbates existing health problems and contributes to pain but also diminishes the motivation to exercise, creating a harmful cycle that can lead to increased disability or dependency. Additionally, low exercise frequency increases the risk of becoming bedridden or requiring care. Therefore, exercise is necessary. The B-SES therapy specifically addresses these challenges by facilitating necessary physical activity.

Therapeutic Approach Substituting Spontaneous Movement: B-SES

Unlike traditional Electrical Muscle Stimulation (EMS) that targets specific muscles, B-SES therapy offers a broader range of electrical stimulation through the use of a belt. It activates all the muscles in the lower limbs, effectively simulating exercise, which marks a significant evolution from conventional methods.

How it differs from traditional pad-type electrodes:
1. Broader coverage: The belt electrode engages all lower limb muscles, acting as a stand-in for physical exercise.
2. Comfortable use: The large surface area of the electrode ensures a wider skin contact area, spreading out the electrical intensity and eliminating discomfort at the points of contact.
3. Ease of application: The design allows for simple placement around the waist, knees, and ankles, avoiding the complexity of attaching electrodes to individual muscles.

This product is particularly beneficial for people who:
• Suffer from weakening muscle strength due to conditions like frailty or sarcopenia.
• Struggle to engage in physical activity because of knee osteoarthritis or back pain.
• Face challenges in exerting themselves physically due to respiratory or cardiovascular issues.
• Require post-care for conditions such as Post-Intensive Care Syndrome or Intensive Care Unit Acquired Weakness.
• Physical therapy or measures are needed to prevent low blood pressure in dialysis treatment settings.
G-TES Enables Targeted Strength and Aerobic Training

G-TES Enables Targeted Strength and Aerobic Training

The G-TES system provides two selectable modes tailored to specific goals:

Disuse (Muscle Strength Training)
In this mode, operating at 20 Hz, muscles undergo intense contractions to simulate the effects of traditional strength training exercises. The objective is to preserve and build muscle strength and volume, improving the user's daily functional abilities.

Metabolism (Aerobic Exercise)
Set at 4Hz, this mode induces repetitive twitching, mirroring the benefits of aerobic exercises. It engages the entirety of the lower limb muscles, boosting oxygen consumption and strengthening the heart and lungs.

The Market's Continued Future Development

In recent years, electrical stimulation devices for pain relief and muscle tension reduction have reached saturation in their primary markets of rehabilitation and orthopedics. On the other hand, electrical stimulation devices that substitute for exercise are not yet on the market, making all hospitals potential new targets for introduction.

This product is being actively used in rehabilitation, dialysis, ICU, and caregiving settings, and G-TES, capable of implementing the B-SES therapy, has already been introduced in over 1,000 facilities domestically in Japan.

Also, English research papers in disciplines like basic medicine, internal medicine, orthopedics, and emergency & ICU have highlighted the significance of this technology.

It is anticipated that this area will see significant development in the future, especially with the ongoing aging of society and the increase in lifestyle-related diseases.
