Rehabilitation equipment is a broad family rather than one standard machine type. Powered treatment tables, continuous-passive-motion devices, compression pumps, therapeutic ultrasound units, electrical stimulators, traction systems, exercise devices, and mobility equipment deliver different physical outputs. Their parts nevertheless follow recurring patterns: structures support loads, motors or generators create output, sensors provide feedback, controls set limits and timing, accessories transfer the output, and protective functions constrain unsafe conditions.
Key takeaways
- Rehabilitation-equipment parts vary by therapy type, but recurring families include structures, actuators, pumps, sensors, controls, cables, batteries, and patient-contact accessories.
- The delivered therapy can depend on both the main unit and the exact supported accessory.
- Mechanical integrity, emergency controls, limits, cleaning compatibility, calibration, and output verification are central service concerns.
01
Major rehabilitation-equipment categories
Powered tables and positioning systems support treatment through lift, articulation, traction, tilt, or controlled motion. Continuous-passive-motion and exercise devices create repeated movement or resistance. Compression systems deliver timed pneumatic pressure. Therapeutic ultrasound and electrical-stimulation units deliver controlled acoustic or electrical energy through supported applicators and patient-connected accessories.
Mobility equipment, patient lifts, standing systems, gait devices, hydrotherapy equipment, warming or cooling systems, and specialty therapy platforms add further mechanical, pneumatic, thermal, electrical, battery, and software boundaries. Begin by identifying the actual therapy or support function rather than searching for a generic rehabilitation part.

02
Motion and mechanical assemblies
Powered tables and motion devices can use motors, linear actuators, lead screws, linkages, gearboxes, belts, chains, bearings, brakes, casters, and position sensors. The controller may compare requested movement with limit-switch, encoder, potentiometer, current, force, or load feedback. Mechanical wear or binding can therefore appear as an electrical or software fault.
Load ratings apply to the complete structure and approved configuration. Welds, pivots, fasteners, upholstery, hand controls, foot controls, supports, restraints, and accessories contribute to safe use. A replacement actuator with similar dimensions may still differ in stroke, force, speed, duty cycle, feedback, limit behavior, mounting, or electrical interface.
- Motors, actuators, gearboxes, lead screws, belts, and bearings
- Limit switches, encoders, potentiometers, current sensing, and load feedback
- Frames, welds, pivots, fasteners, supports, brakes, and casters
- Hand controls, foot controls, emergency stops, and motion lockouts
03
Compression-system parts
Intermittent and sequential compression systems regulate air through pumps or blowers, intake filters, valves, manifolds, pressure sensors, tubing, connectors, and supported garments. The controller coordinates inflation sequence, pressure, timing, channel status, leak detection, and alarms according to the design.
A slow-inflation or pressure complaint can involve a garment, hose, connector, seal, valve, filter, pump, sensor, manifold, power supply, or configuration. The garment is part of the functional system and can carry identification, size, chamber arrangement, cleaning limits, and replacement criteria.
04
Therapeutic ultrasound and stimulation parts
Therapeutic-ultrasound units coordinate a generator, impedance or output-monitoring circuits, applicator, cable, connector, coupling interface, timer, controls, and display. Electrical-stimulation systems manage waveform generation, isolation, output stages, channel controls, leads, electrodes, connectors, and patient-applied-part limits.
The same display symptom can originate in the output stage, applicator, lead, electrode, cable, sensor, power distribution, configuration, or user interface. Similar-looking applicators and leads can have different frequency, area, output, pinout, identification, isolation, or approved-use characteristics.
05
Controls, sensors, batteries, and accessories
Displays, keypads, touch panels, hand switches, footswitches, emergency controls, timers, remote controls, batteries, chargers, power supplies, memory, and communication interfaces make the device usable. Force, pressure, position, temperature, current, impedance, contact, and motion sensors can contribute to control or protective functions.
Patient-contact accessories may carry identification, calibration, wear limits, cleaning restrictions, expiration, or a defined service life. Document the main unit together with the applicator, garment, lead, electrode, table accessory, remote, software level, connector, output option, battery, and charger.
06
Identifying rehabilitation-equipment parts
Record manufacturer, product family, exact model and serial number, equipment category, therapy or motion function, hardware and software revision, part or assembly number, connector, mounting, voltage, feedback type, stroke or output rating where documented, patient-contact classification, supported accessories, and cleaning requirements.
Separate a number printed on an internal component from the orderable service assembly. Motors, pumps, batteries, power supplies, displays, and generic-looking cables can be modified, programmed, calibrated, keyed, or packaged specifically for one equipment family. Compatibility should come from controlled documentation or an accountable source.
07
Verification after service
A useful return-to-service plan matches the equipment's actual risks: mechanical stability and motion limits for tables, pressure and timing for compression, electrical output and isolation for stimulation, acoustic output where required for ultrasound, load or position behavior for motion systems, and battery or charger performance for mobile devices. Visual inspection alone may not evaluate the controlled output.
Test equipment, fixtures, procedures, tolerances, cleaning or decontamination, accessories, and documentation must be appropriate to the exact device. Clinical setup and treatment selection remain outside the role of a general technical reference.
Therapy equipment can create electrical, thermal, pressure, motion, pinch, fall, and patient-contact hazards. Service and output testing require qualified personnel, appropriate test equipment, controlled manufacturer procedures, and facility return-to-use approval.
