This page describes products and general use; it is not medical advice.
A physical therapy equipment list is easiest to use when each item is tied to what the federal regulation calls it. Under 21 CFR Part 890 (Physical Medicine Devices), the items in a physical therapy or occupational therapy clinic fall into named device types, and each type has a risk class. This page lists the equipment by category, names the regulation section for each, and shows which items are Class I and which are Class II or III. It is written for clinic staff, buyers and students who need to know what a clinic’s equipment is, not which brand to buy.
What counts as physical therapy equipment?
Physical therapy equipment is the set of devices a clinic uses to restore motion, build strength, apply heat or cold, deliver electrical or ultrasound energy, position patients and support walking and daily tasks. In U.S. regulation, most of these are medical devices described in 21 CFR Part 890. Subpart F covers physical medicine therapeutic devices (exercise, heat and cold, stimulation, traction, tables). Subpart D covers physical medicine prosthetic devices, which also holds the mobility and daily-living items occupational therapists use.
The FDA sorts devices into three classes: “Class I includes devices with the lowest risk and Class III includes those with the greatest risk.” Class I is regulated by General Controls, Class II by General Controls and Special Controls, and Class III by General Controls and Premarket Approval (FDA, Classify Your Medical Device, checked 2026-10-31). The FDA page adds that some Class I devices are exempt from premarket notification; for many Part 890 types the regulation states this exemption itself, “subject to the limitations in 890.9”.
This page lists devices. Disposable supplies such as covers, tapes and cleaning products are a separate topic, covered in the physical therapy clinic supply checklist. For the general definition of a device, see what is a medical device.
Exercise and strengthening equipment
The regulation splits exercise equipment by whether it measures and whether it is powered. Nonmeasuring equipment is defined as “devices intended for medical purposes, such as to redevelop muscles or restore motion to joints,” and the listed examples are a prone scooter board, parallel bars, a mechanical treadmill, an exercise table and a manually propelled exercise bicycle. Powered versions (a powered treadmill, a powered bicycle, powered parallel bars) are a separate section. Equipment that adds instrumentation, such as a therapeutic exercise bicycle with measuring instrumentation or a rowing machine with measuring instrumentation, is Class II.
Resistance bands are a common item in this group; see how resistance bands work and the TheraBand color chart for resistance values.
Hot, cold and compression equipment
Heat and cold devices span Class I and Class II depending on how they work. A silica-gel moist heat pack and a gel cold pack are Class I; a pad that is electrically powered or a pack with pumped water is Class II. See moist heat packs and the hot and cold therapy selection guide.
Electrotherapy and ultrasound devices
Devices that deliver energy to tissue carry the higher classes. The powered muscle stimulator (“an electrically powered device intended for medical purposes that repeatedly contracts muscles by passing electrical currents through electrodes”) is Class II. Ultrasonic diathermy for therapeutic deep heat is Class II, while ultrasonic diathermy for all other uses is Class III. For the device itself, see what is therapeutic ultrasound.
Treatment tables, traction and positioning
The regulation draws a line between the plain table and the multi-function table. A plinth is “a flat, padded board with legs” and is Class I; a multi-function physical therapy table, “a motorized table equipped to provide patients with heat, traction, and muscle relaxation therapy,” is Class II. Power traction equipment, used with traction accessories such as belts and harnesses, is Class II, while the accessories themselves are Class I. See what is a plinth.
Mobility and daily-living aids (occupational therapy equipment)
Occupational therapy equipment overlaps with the same regulation. A daily activity assist device is “a modified adaptor or utensil (e.g., a dressing, grooming, recreational activity, transfer, eating, or homemaking aid)” and is Class I. Canes, crutches, mechanical walkers and mechanical wheelchairs are Class I; a powered wheelchair is Class II. Nonpowered communication systems, such as an alphabet board or a page turner, are Class I, while powered communication systems are Class II. Related guides: canes, walkers, crutches and gait belts. For the profession itself, see what is occupational therapy.

Common mistakes when reading an equipment list
- Mixing devices and supplies. Treatment furniture, modalities and mobility aids are devices with a class; covers, linens and cleaning products are consumables and belong on a supply list.
- Assuming powered and nonpowered versions share a class. A moist heat pack is Class I (890.5730) but a powered heating pad is Class II (890.5740); a plinth is Class I (890.3520) but a multi-function table is Class II (890.5880).
- Assuming a measuring version is the same as a plain one. Exercise equipment with measuring instrumentation is Class II (890.5360); the nonmeasuring version is Class I (890.5370).
- Treating Class I as meaning no rules. The FDA states General Controls apply to all medical devices in Classes I, II and III.
FAQ
What is on a physical therapy equipment list?
Exercise equipment, hot and cold packs, electrotherapy and ultrasound devices, treatment tables and traction, and mobility and daily-living aids. The table above names the 21 CFR Part 890 section and FDA class for each.
What counts as occupational therapy equipment?
Occupational therapy equipment overlaps with the same regulation: daily activity assist devices (dressing, grooming, eating and homemaking aids, 890.5050), canes, crutches, walkers, wheelchairs and communication systems are all Part 890 device types, and all but the powered wheelchair and powered communication system are Class I.
Are all physical therapy devices Class I?
No. Heat packs, plinths and nonmeasuring exercise equipment are Class I, but powered muscle stimulators, multi-function tables, power traction and measuring exercise equipment are Class II, and ultrasonic diathermy for uses other than deep heat is Class III.
