| Patient Safety | Emergency stop or rapid-release function; clearly visible controls; stable locking mechanism; documented operating limits. | Allows the operator to stop treatment quickly and helps prevent unintended movement or excessive loading. | 25% | Check the user manual, risk controls, load limits, emergency-release operation, and applicable medical-device compliance documents. |
| Traction Control | Adjustable force, hold time, rest time, and treatment cycles; gradual ramp-up and ramp-down rather than abrupt loading. | Controlled adjustment supports individualized treatment and reduces sudden force changes. | 15% | Confirm whether settings are displayed clearly and whether the system preserves the selected parameters during a session. |
| Patient Comfort | Multi-position padding, rounded contact surfaces, breathable upholstery, and adjustable pelvic or thoracic support. | Comfort can influence patient relaxation, positioning stability, and willingness to complete a treatment course. | 15% | Test the table with different body sizes and verify that straps and cushions do not create concentrated pressure points. |
| Patient Capacity and Fit | Rated working load should exceed the heaviest intended patient by a practical safety margin; usable surface should accommodate the target patient population. | A suitable size and verified load rating reduce positioning problems and mechanical stress. | 10% | Compare the manufacturer’s rated load, table dimensions, height range, and access requirements with local clinical needs. |
| Frame Stability | Rigid frame, low lateral movement, secure casters or leveling feet, and smooth motion without excessive vibration. | A stable platform supports consistent positioning and helps reduce the risk of unintended table movement. | 10% | Operate the table at its lowest and highest positions and inspect joints, locks, wheels, and moving sections. |
| Durability and Materials | Powder-coated or corrosion-resistant metal frame; replaceable upholstery; reinforced seams; components rated for repeated clinical use. | Durable construction can reduce downtime, repair frequency, and long-term ownership cost. | 10% | Request service intervals, spare-parts availability, upholstery replacement details, and warranty terms. |
| Ease of Use | Intuitive hand control or foot control, readable displays, quick patient access, and minimal setup steps. | Simple operation can improve workflow efficiency and reduce setup errors. | 7% | Ask staff to complete a full setup and shutdown procedure without assistance and record the time required. |
| Cleaning and Infection Control | Non-porous, seamless or easy-to-clean surfaces; upholstery compatible with the facility’s approved disinfectants. | Accessible surfaces and material compatibility support consistent cleaning between patients. | 5% | Review cleaning instructions and confirm that disinfectants will not damage upholstery, labels, seals, or controls. |
| Noise and Operating Environment | Smooth, low-noise motor or mechanical operation; power requirements compatible with the treatment room. | Lower noise can improve communication and patient comfort during treatment. | 3% | Request operating-noise information where available and test the table during height adjustment and traction cycles. |
