Physical Agent Modalities (PAM’s) for Occupational Therapists and Occupational Therapy Assistants is designed as an introductory course to educate occupational therapy practitioners in the use of physical agents in the areas of electrotherapy and ultrasound. The physical principles and biophysical effects of cryotherapy, heat, ultrasound and electrical currents are presented …
A modality is a type of electrical, thermal or mechanical energy that causes physiological changes. It is used to relieve pain, improve circulation, decrease swelling, reduce muscle spasm, and deliver medication in conjunction with other procedures.
Therapeutic modalities represent the administration of thermal, mechanical, electromagnetic, and light energies for a specific therapeutic effect; for example, to decrease pain, increase range of motion (ROM), improve tissue healing, or improve muscle activation.
Physical agent modalities are those procedures and interventions that are systematically applied to modify specific client factors when neurological, musculoskeletal, or skin conditions are present that may be limiting occupational performance.
One class of treatments are called physical agent modalities (PAMs). The American Occupational Therapy Association (AOTA) describes PAMs as equipment including superficial and thermal agents, electrotherapeutic agents, and mechanical devices designed to assist patients in their daily lives.Jan 11, 2022
Ultrasound is a modality that uses sound waves emitted by a transducer probe which is in contact with the skin. As they reflect off structures with different depths, the sound waves return to the probe with varying intensities and they are recorded by a processing unit and displayed on a screen (10).Apr 25, 2018

Physical agent modalities include those treatments that use the proper- ties of light, water, temperature, sound, and electricity to produce a response in soft tissue, for example, paraffin, hot and cold packs, fluidotherapy, and ultrasound (American Occupational Therapy Association [AOTA], 1991).
Ultrasound therapy is a treatment used by physical therapists or occupational therapists to relieve pain and to promote tissue healing. While ultrasound therapy is not effective for all chronic pain conditions, it may help reduce your pain if you have any of the following: Osteoarthritis.Mar 17, 2022
Deep heat modalities include ultrasound, shortwave diathermy (SWD) and microwave diathermy (MWD). Ultrasound is however the most used deep heating agent. Heat penetration can be 3-5 cm or more without overheating underlying subcutaneous tissue or skin. Transfer method: Same as superficial heat but deeper penetration.Mar 11, 2021
Depending on the type of current used, these modalities can help relieve pain, reduce edema and inflammation, promote tissue healing, and facilitate muscle function and strength.May 19, 2021
These may include: TENS: Transcutaneus electrical neuromuscular stimulation (TENS) is a physical therapy modality used to manage acute and chronic pain in physical therapy.
Physical agent modalities may not be used as a stand-alone treatment because alone, physical agent modalities do not align with service standards described in the scope of practice of occupational therapy, i.e. "a program of purposeful activities to develop or maintain adaptive skills...."Apr 15, 2021

Therapeutic ultrasound is a treatment modality commonly used in physical therapy. It is used to provide deep heating to soft tissues in the body. These tissues include muscles, tendons, joints, and ligaments.
Ultrasound is often used to provide deep heating to soft tissue structures in the body. Deep heating tendons, muscles, or ligaments increases circulation to those tissues, which is thought to help the healing process. Increasing tissue temperature with ultrasound is also used to help decrease pain.
There are some instances where you should not use ultrasound at all. These contraindications to ultrasound may include: 1 Over open wounds 2 Over metastatic lesions or any active area of cancer 3 Over areas of decreased sensation 4 Over parts of the body with metal implants, like in a total knee replacement of lumbar fusion 5 Near or over a pacemaker 6 Pregnancy 7 Around the eyes, breasts, or sexual organs 8 Over fractured bones 9 Near or over an implanted electrical stimulation device 10 Over active epiphyses in children 11 Over an area of acute infection
Ultrasound is performed with a machine that has an ultrasound transducer (sound head). A small amount of gel is applied to the particular body part; then your physical therapist slowly moves the sound head in a small circular direction on your body.
If you have shoulder pain and have been diagnosed with a frozen shoulder, your physical therapist may use ultrasound to help improve the extensibility of the tissues around your shoulder prior to performing range of motion exercises. This may help improve the ability of your shoulder to stretch.
Your physical therapist may use ultrasound to help improve your condition. If so, be sure to ask about the need for ultrasound and possible risks. Also, be sure that you are also performing an active self-care exercise program in the PT clinic and at home. If you are actively engaged in your rehabilitation, you can ensure that you have a safe and rapid recovery back to normal function.
Two types of cavitation include stable and unstable cavitation. Stable cavitation is desired when your physical therapist is applying ultrasound to your body. Unstable cavitation can be dangerous to your body's tissues, and your physical therapist will ensure that this does not occur during the application of ultrasound.
The absorption of US energy follows an exponential pattern - i.e. more energy is absorbed in the superficial tissues than in the deep tissues. In order for energy to have an effect it must be absorbed, and at some point this must be considered in relation to the US dosages applied to achieve certain effects (ter Haar, 1999, Watson, 2008, Watson and Young, 2008).
There are a growing number of ‘other applications’ for ultrasound energy ranging from tumour ablation – using High Intensity Focussed Ultrasound (or HIFU) though to stimulated related of encapsulated systemic drugs. HIFU is beyond the scope of this review which is mainly concerned with 'standard' therapy ultrasound.
FREQUENCY - the number of times a particle experiences a complete compression/rarefaction cycle in 1 second. Typically 1 or 3 MHz (though there are devices which operate in the kHz range - see comments on Low Frequency / Longwave Ultrasound at the end of this paper).
The US beam is not uniform and changes in its nature with distance from the transducer. The US beam nearest the treatment head is called the NEAR field, the INTERFERENCE field or the Frenzel zone. The behaviour of the US in this field is far from regular, with areas of significant interference. The US energy in parts of this field can be many times greater than the output set on the machine (possibly as much as 12 to 15 times greater).
In thermal mode, US will be most effective in heating the dense collagenous tissues and will require a relatively high intensity, preferably in continuous mode to achieve this effect.
All materials (tissues) will present an impedance to the passage of sound waves. The specific impedance of a tissue will be determined by its density and elasticity. In order for the maximal transmission of energy from
The critical angle for US at the skin interface appears to be about 15. If the treatment head is at an angle of 15 or more to the plane of the skin surface, the majority of the US beam will travel through the dermal tissues (i.e. parallel to the skin surface) rather than penetrate the tissues as would be expected.
