It is designed for chiropractors with limited hand strength or dexterity, such as those with arthritis or physical disabilities. Unlike traditional plunger-style devices, it features a gun-like configuration and is activated pneumatically via a push-button. The device delivers a repeatable force and displacement to the spine and extremities using spring energy. It includes a precision force setting feature and a silicone rubber body contact member. The device is operated by a chiropractor to perform adjustments, providing a therapeutic benefit through controlled mechanical force application. ## Clinical Evidence Bench testing only. An independent laboratory compared the Frye Adjusting Instrument to the FS Activator® III. Results demonstrated that both devices produce similar peak dynamic loads at minimum, mid, and maximum settings. ## Technological Characteristics Hand-held chiropractic adjusting device. Features a gun-like configuration with pneumatic push-button activation. Utilizes spring energy to deliver impact force. Includes adjustable force settings and a silicone rubber body contact member. Mechanical device; no software or electronic components. ## Predicate Devices - FS Activator® III ([K003185](/device/K003185.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Activator Methods, Phoenix, Arizona | | #### Intended Use: The Frye Adjusting Instrument is intended for chiropractic adjustment of the spine and extremities. #### Device Description: The Frye Adjusting Instrument is a chiropractic, adjusting instrument for use in spinal manipulative therapy. The Frye Adjusting Instrument is a modification of the Full Spectrum Activator® III Adjusting Instrument developed to offer easier use to those chiropractors that have limited strength or dexterity in their hands. Typically, these are chiropractors that have arthritis, age-related problems, or have a physical disability of their upper extremity. Thus, these chiropractors have difficulties using currently available adjusting instruments. The main differences between currently available adjusting instruments, such as the FS Activator® III, and the Frye adjusting instrument are that the Frye adjusting instrument is activated pneumatically by a simple push-button and it is shaped in a 'gun-like' configuration rather than a 'plunger-like' configuration. {1}------------------------------------------------ K021238 page 2 of 62 # Comparison to predicate device: Like the FS Activator® III, the Frye Adjusting Instrument is a manual hand-held chiropractic adjusting device which provides a repeatable force and displacement to the spine and extremities when activated. Both devices have a precision force setting feature and a silicone rubber body contact member.
