LegXercise Pro

Device maker does not have the clinical proof to back up its clinically proven claims.


UPDATE 1/21/24: The National Advertising Division has recommended that IntelliBrands discontinue a number of health-related claims for its LegXercise products, including its Pro device, after concluding that the company failed to properly substantiate the health claims in response to the self-regulatory group’s inquiry. In support of claims that its products soothe leg pain, reduce swelling in legs, ankles and feet, and increase leg circulation, among other things, IntelliBrands submitted (1) articles about the impact of passive exercise that NAD found did not involve the use of a LegXercise device and (2) the study discussed in the ad alert below. In its case report, NAD raised some of the same issues with the study as did, including the lack of a control and a reliance on subjective self-reporting rather than objective measures. The study contained several flaws that rendered it unreliable, NAD found. In its advertiser statement to NAD, IntelliBrands said it agreed to comply with the decision. Our original ad alert follows.

IntelliBrands advertises that its “automatic leg mover” device the LegXercise Pro is “clinically proven” to soothe pain and promote healthy circulation in legs the “drug-free way.” Unfortunately for those with leg pain, the company does not have the clinical proof to back up its clinically proven claims.

“Have you ever felt leg pain, restlessness, cramps, tingling, swelling, numbness, itchiness or coldness?” the company volunteers in the commercial above. “Then you need the new clinically proven LegXercise Pro, the natural circulation booster that uses continuous automatic leg movement to soothe pain and promote healthy circulation the natural, drug-free way.”

The ad shows people encountering sudden leg pain – you’ve seen infomercials – and then finding relief with the LegXercise Pro, which mimics walking by moving the feet back and forth along a concave track while the user remains seated. The device costs $200.

If you watch any TV, you may have already seen the spot as it’s aired more than 5,000 times across numerous networks since its debut in March 2022, for an estimated national TV ad spend of $2.9 million, according to In fact, was alerted to the ad by a reader, who expressed doubt about the company’s claims after finding “no mention of products being ‘clinically proven’” on the LegXercise website.

Our reader was correct to be skeptical. While IntelliBrands does not publish the study that serves as the basis for its clinically proven claims for its LegXercise Pro device, the company provided it to in response to a media inquiry. And the study has a number of noteworthy concerns, including:

  • IntelliBrands sponsored the study.
  • A small sample size: 44 subjects completed the study, only 16 of which were actually tested for improvements in blood flow “due to limitations of the instrument” used to collect readings.
  • A methodology that largely relied on responses to a “subjective questionnaire” taken two weeks after using the LegXercise Pro.
  • A short period of time during which subjects were instructed to use the device at home without any supervision.
  • Informing subjects about the “potential benefits” of the study, including a reduction in “pain sensations in lower leg, ankles and feet,” before the study even started.
  • A sample population that was more than 80 percent white, which is not representative of the general population.
  • The absence of a control group.

In its inquiry informed IntelliBrands that, under FTC law, “clinically proven” claims require the support of competent and reliable scientific evidence in order to not be misleading. told the company that the study it provided does not support the marketing message that it is promoting and asked when it will correct its deceptive marketing.
