Panasonic has released four limited-edition colors of its high-frequency therapy device "CoriCoran Loop" (EW-RA520) on September 10, 2026: Energy Yellow, Midnight Blue, Mint Green, and Sakura Pink. Alongside the launch, the company published the results of a survey on shoulder stiffness among gamers, and is promoting the product to the gaming audience at Tokyo Game Show 2026.

Survey Finds 66.1% of Gamers Suffer from Shoulder Stiffness

On September 8, 2026, Panasonic released the results of a "Survey on Shoulder Stiffness and Gaming," based on a screening survey of 4,388 men and women aged 18 to 59 nationwide, a main survey of 1,000 people who play games at least once a week, and a detailed analysis of 631 respondents who reported being aware of shoulder stiffness. According to the survey, 66.1 percent of respondents who play games at least once a week said they were aware of shoulder stiffness, and 49.1 percent of them said they lose their sense of comfort within an hour of starting to play. 80.5 percent said they had cut short or paused a gaming session because of shoulder stiffness, and 62.2 percent of that group said they felt frustrated about it.

In addition, 64.5 percent said they find it hard to notice shoulder stiffness while absorbed in a game, and 41.8 percent of those who do not take any countermeasures said they do not know how to treat it. Among PC gamers specifically, 76.4 percent said the length of time they can concentrate has declined compared with when they were children.

Four New Colors, Limited Edition

The CoriCoran Loop EW-RA520 is a home-use electrotherapy device that places four high-frequency units around the muscles supporting the back of the neck to improve stiffness by promoting blood flow. Unlike low-frequency devices, it does not produce the tingling sensation that can interrupt focus, which Panasonic positions as a benefit for continued use during work or gameplay. Its twisted-fit shape is designed to sit comfortably around the neck, with a moisture-resistant design and a U-shaped magnet to prevent slipping or falling off.

The device previously came in black and greige. This release adds four new limited-edition colors — Energy Yellow, Midnight Blue, Mint Green, and Sakura Pink. Pricing is open (set by individual retailers).

Panasonic Sets Up an Experience Booth at Tokyo Game Show 2026

At Tokyo Game Show 2026, held from September 17, 2026 at Makuhari Messe in Chiba Prefecture, Panasonic has set up an experience booth for CoriCoran Loop, presenting it as a countermeasure for the shoulder stiffness that builds up during long gaming sessions. The company's presence at a gaming event appears to stem directly from the survey results, which show that shoulder stiffness is a widespread concern among gamers.

The product's certification as a medical device (certification number 306AKBZX00052000) is also part of its appeal, positioned as an easy way to care for shoulder stiffness even while continuing to play. Panasonic has also produced promotional content featuring professional gamers, an example of a home appliance maker looking to esports and gaming as a new customer touchpoint.

Summary

Panasonic released four limited-edition colors of its CoriCoran Loop EW-RA520 high-frequency therapy device on September 10, 2026, alongside survey results showing that 66.1 percent of gamers are aware of shoulder stiffness. The company has also set up an experience booth at Tokyo Game Show 2026, proposing the device as a way for gamers to manage the shoulder stiffness that builds up during long play sessions.
