The intended use of the ZEGRA Posture Trainer is a postural reminder for people who have the habit of slumped posture, who wish to be reminded of their posture whenever they slump beyond a predetermined limit, and who have the ability to correct their posture, The ZEGRA Posture Trainer's feedback helps to reduce slumped posture within this population.

The intended use is for Prescription Use and Over-The-Counter Use.

Device Description

The ZEGRA Posture Trainer is worn and looks just like the predicate posture trainer by the name of SPINE TUNER (510k Number: K951244). It is strapped around the chest with a belt or a bra. All electronic components sit in a little plastic case. The case contains a part that is moved when the user slumps. This movement is picked up by a sensor within the case. When the ZEGRA Posture Trainer is switched on, a microprocessor records the current posture as posture threshold. Thereafter, the ZEGRA Posture Trainer will vibrate whenever this threshold posture is reached or surpassed by slumping too much. The user has a choice of immediate feedback or feedback with a few seconds delay. The ZEGRA Posture Trainer has no cables and no options for connecting with other devices. It is exclusively battery powered.

AI/ML Overview

The provided text describes a 510(k) submission for the ZEGRA Posture Trainer (K081540). However, it does not contain any information regarding acceptance criteria, device performance studies, sample sizes, expert ground truth establishment, or any of the specific study details outlined in your request.

The document is primarily a 510(k) summary and the FDA's decision letter, which focuses on device description, intended use, and substantial equivalence to a predicate device. It explicitly states that the predicate device is an "unclassified pre-amendments device" and that the ZEGRA Posture Trainer is expected to be classified in the same way. This type of submission relies on demonstrating substantial equivalence to a legally marketed device rather than providing extensive clinical performance data against specific acceptance criteria.

Therefore, I cannot populate the table or answer the specific questions about studies, sample sizes, or ground truth as this information is not present in the provided text.

Device description:

The intended use of the ZEGRA Posture Trainer is a postural reminder for people who have the habit of slumped posture, who wish to be reminded of their posture whenever they slump beyond a predetermined limit, and who have the ability to correct their posture. The ZEGRA Posture Trainer's feedback helps to reduce slumped posture within this population.

Substantial equivalence:

Intended use:

A sensor and feedback unit encased in a plastic housing. The housing being attached to the body via a belt or bra. The sensor being sensitive to spinal curvature. A vibratory feedback signal whenever and as long as the spine is flexed beyond a predetermined limit.

Battery power as the only energy source.

A target population that wants to improve its posture and has the ability to do so.

Main difference to predicate:

Main difference to predicate: The ZEGRA posture trainer has a choice of immediate and delayed feedback, while the predicate device only offers immediate feedback.

Dear Mr. Fisher:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing may regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
