The Spine Gun 400N Chiropractic Physiotherapy Tool is an electrically powered handheld instrument designed for professional chiropractic and musculoskeletal therapy environments. It uses a controlled mechanical impulse mechanism to deliver targeted pressure through a treatment applicator. The device is designed to support practitioners who require an adjustable-force tool for selected manual therapy and chiropractic treatment procedures.
With a maximum force rating of 400N and commonly listed adjustment levels of 100N, 200N, 300N and 400N, the Spine Gun 400N offers different force settings for professional use. Its handheld design allows the practitioner to position the applicator over selected treatment areas according to the clinical assessment and the manufacturer’s instructions.
The Spine Gun 400N Chiropractic Physiotherapy Tool may be considered for professional physiotherapy clinics, chiropractic practices, rehabilitation centres and other suitable clinical environments. It should only be operated by trained professionals familiar with the equipment and its safety requirements.
PHYSIOMODALITIES™ provides physiotherapy and rehabilitation equipment for professional clinical settings.

What Is a Spine Gun 400N Chiropractic Physiotherapy Tool?
A Spine Gun 400N is an electrically powered chiropractic adjustment instrument designed to deliver controlled mechanical impulses through a handheld applicator.
Unlike conventional massage guns that primarily provide repetitive soft-tissue percussion, a chiropractic adjustment instrument is designed around a more focused impulse mechanism. The practitioner selects the appropriate force setting and positions the applicator according to the intended treatment technique.
The 400N rating refers to the maximum force stated for the product configuration. It should not be interpreted as a measure of clinical effectiveness or as an indication that the highest setting is suitable for every patient.
The tool is intended to support professional treatment procedures and does not replace clinical examination, diagnosis or an appropriately selected rehabilitation plan.
How Does the Spine Gun 400N Work?
The Spine Gun 400N uses an electric mechanism to generate controlled mechanical impulses through its applicator.
The general operating process involves:
- The practitioner assesses the patient and identifies the appropriate treatment area.
- The device is connected to its specified power supply.
- The practitioner selects an appropriate force level.
- A compatible treatment head is fitted, if interchangeable heads are supplied.
- The applicator is positioned according to the manufacturer’s technique.
- The device delivers mechanical impulses when activated.
- The practitioner monitors the patient’s response throughout the procedure.
The precise impulse mechanism, frequency and available operating modes depend on the supplied model.
