What It Is
The Zenith Hylo and Verti-Lift chiropractic tables are mechanical tables designed to assist chiropractors in performing spinal adjustments and other manual therapies. These tables can adjust in height and position, allowing for optimal patient positioning and practitioner ergonomics. The 'Hylo' feature enables the table to tilt, while the 'Verti-Lift' allows for vertical height adjustments, providing versatility in treatment approaches.
FDA-Cleared Indications
- Positioning and supporting patients during chiropractic spinal adjustments.
- Positioning and supporting patients during manual therapy procedures.
- Adjusting patient height and table position to facilitate treatment.
Clinical Applications
- Chiropractic spinal adjustment procedures.
- Manual therapy for musculoskeletal conditions.
- Patient positioning during chiropractic treatment.
- Height adjustment for clinician access and treatment ergonomics.
- Tilt positioning during manual therapy procedures.
Practical Considerations
- The Hylo function provides table tilting, while the Verti-Lift function provides vertical height adjustment.
- The table should be operated according to the manufacturer's instructions, including stated patient weight limits and positioning requirements.
- Regular inspection and maintenance are important for mechanical components, table stability, and adjustment mechanisms.
- These mechanical tables are not medical imaging devices and should not be assumed to be MRI compatible; confirm compatibility with the manufacturer before use in or near an MRI environment.
- Assess patient mobility, stability, and ability to tolerate the required position before manual therapy.
