Testing health gear for WIRED means I work out six days every week, generally twice every day. So after I received my fingers on the PowerDot 2.0 Duo, I used to be excited to see whether or not it might ease my post-workout soreness. At-home units like this goal to commercialize medical expertise that was as soon as reserved for elite athletes. PowerDot was acquired by Therabody in 2021 and is without doubt one of the main devices on this area, billing itself as “the world’s first good muscle stimulator.”
The PowerDot 2.0 combines two noninvasive therapies: neuromuscular electrical stimulation (NMES) and transcutaneous electrical nerve stimulation (TENS). Managed by a companion app, it is an intriguing restoration instrument with simple potential but additionally notable flaws.
A 2-for-1 Deal
The PowerDot 2.0 makes use of three adhesive electrodes to ship electrical pulses to your pores and skin. NMES stimulates motor nerves, mimicking mind indicators to set off muscle contractions. This course of can enhance blood circulation, assist ship vitamins to points, and help restoration from muscle fatigue or accidents.
TENS targets the sensory nerves to briefly block ache indicators and stimulate endorphin manufacturing (the physique’s pure painkiller). It is notably efficient for circumstances like decrease again ache, postoperative discomfort, and dysmenorrhea. Research truly counsel TENS can supply larger reduction for menstrual ache than nonsteroidal anti-inflammatory medicine (like ibuprofen). Collectively, these applied sciences intend to deal with each muscle restoration and ache reduction.

Whereas NMES has proven potential in decreasing blood lactate ranges, an indicator of muscle fatigue, its impression is extra supportive than transformative. Additionally, to reap the advantages, the stimulation have to be intense sufficient to activate muscle tissues with out including to the fatigue.
It’s value noting that the effectiveness of each applied sciences can range relying on components like physique composition and particular person thresholds to electrical stimulation. One other disclaimer is that Therabody hasn’t printed any medical information or research particular to PowerDot, as a substitute referencing common analysis on NMES and TENS. This lack of understanding makes it exhausting to validate the corporate’s claims concerning the gadget’s meant goal.

The Duo package deal contains: two pods, three adhesive electrode pads (one rectangular and two spherical), two units of lead cables (10 cm and 30 cm), two micro USB charging cables, and a protecting case. It’s moveable—smaller than a novel—and simple to journey with. The hydrogel pads final for 20 to 30 periods earlier than dropping their stickiness, at which level they should be changed ($18 per Duo set). The app tracks pad lifespan so that you don’t need to, and with care, you would possibly eke out a number of further periods. Simply knock on wooden you don’t drop one face-down.
Aid, With Caveats
In apply, the PowerDot delivered blended outcomes. When it labored, it did make me really feel much less stiff for my subsequent exercise. The interval ache reduction program was my favourite function, however the ache reduction was short-lived, restricted to the session’s period. The tingling sensation can really feel uncomfortable, particularly at first, nevertheless it’s tolerable and you’ll regulate it to your consolation.
The second pod is a serious benefit, letting you goal either side of a muscle group concurrently. This cuts session instances in half and reduces put on on the pads. When you personal the Uno, you possibly can improve by buying a second pod.
PowerDot is absolutely managed by its companion app, which lets you select particular muscle teams or restoration applications, regulate depth ranges, and monitor periods. The app itself makes the expertise really feel approachable, together with for these new to electrical stimulation units. You’ll have to obtain the separate PowerDot app, because the gadget doesn’t sync with the Therabody app—not an enormous deal, however value mentioning.
