Modalities we use

At Therapeutic Dynamics, we offer modalities such as ultrasound, iontophoresis, phonophoresis, electrical stimulation, cryotherapy, paraffin, moist heat and ice packs to assist in the progression of the patient’s rehabilitation.

Therapeutic Ultrasound is a method of stimulating tissue beneath the skin’s surface, using sound waves. It is sort of a very high frequency sound massage, which can penetrate up to 4 inches below the surface of your skin. us 3 The sound waves are very high frequency, typically between 800,000 Hz and 2,000,000 Hz. This sound cannot be heard by humans or animals. Humans can only hear sounds up to about 20,000 Hz. This very high frequency sound, like medicine, affects very small molecules and cells in the body and actually causes them to vibrate. Through a process called vasodilation, the stimulation created by the ultrasound unit will cause your body to pump oxygen and nutrient rich blood to the treated area. This supply of fresh blood means a higher rate of healingreduced swelling, and faster recovery from injuries.


Neuromuscular Re-education

Neuromuscular Electrical Nerve Stimulation (NMES) is the application of an electrical stimulus for muscle rehabilitation. During NMES, an electrical stimulus is passed from the device to an electrode placed on the skin over a targeted muscle or muscle group  mimicking the central nervous system causing the muscles to contract as they would naturally. The impulses are generated by a device such as a NMES unit and delivered through electrodes on the skin.  These electrodes are placed on the muscle that needs stimulation.nmer

Physical therapy with NMES machines is effective in preventing muscle atrophy due to disuse of a muscle or muscle groups.  It is used primarily after musculoskeletal injuries such as damage to ligaments, tendons, joints, muscles, and bones.  Though they look similar, it differs from TENS units. Transcutaneous electrical nerve stimulation machines use an electric current for pain therapy rather than muscle stimulation. Patients with a wide range of orthopedic and neurologic diagnoses can benefit from the use of NMES. 


Electrical Stimulation

Electrical stimulation uses an electrical current to cause a single
muscle or a group of muscles to contract. By placing electrodes on the skin in various locations the physical therapist can recruit the appropriate muscle fibers. Contracting the muscle via electrical stimulation helps strengthen the affected muscle. The physical therapist can change the current setting to allow for a forceful or gentle muscle contraction. Along with increasing muscle strength, the contraction of the muscle also promotes blood supply to the area that assists in healing.

Dexamethasone Iontophoresis  

iontophoresis dexamethasone treatment

 Iontophoresis is a technique of introducing ionic medicinal compounds (Dexamethasone) into the body through the skin by applying a local electric current. It is a safe, well-documented method of increasing penetration of molecules into surface tissues. Iontophoresis uses locally applied direct current to deliver medications across skin. Certain Iontophoresis delivery method therapeutic dynamicsscientific principles describe iontophoresis as a way to passively diffuse medication into the skin. The basic principle used is that electrical energy assists the movement of ions across the stratum corneum according to the basic electrical principle “like charges repel each other and opposite charges attract each other”.



phonophoresis ultrasound Phonophoresis uses an ultrasound machine to push medicine deep into your joints or muscles. An ultrasound machine makes sound waves that are too high for the human ear to hear. These sound waves travel through your skin and into your body. A gel is used betweenphonophoresis treatment ultrasound the head of the ultrasound machine and the skin to help the sound waves enter your body. Ultrasound waves create the effect of deep heat in your muscles and joints.
In phonophoresis, we use add a compounded medicine called Dexamethasone Phonophoresis Ultrasound Gel. The sound waves from the ultrasound machine push this medicine deep into your body.  With phonophoresis you get the effects of the ultrasound as well as the medicine.


Lumbar/Cervical Traction

mechanical traction

Mechanical spinal traction is the use of mechanical devices that exert a pulling force through a rope and various halters and straps. The tractive force results in a longitudinal separation and gliding apart of cervical (neck) or lumbar (back) spinal segments

The main purpose of mechanical traction is to reduce symptoms of cervical (neck) or lumbar (back) spinal compression. This is accomplished by allowing increased space for spinal nerves, elongating muscle tissue, decreasing sensitivity and muscle guarding, decreasing intradiscal pressure and increasing blood supply to the disc. Decreasing the pressure of the disc may help retract the disc bulges.

Mechanical spinal traction may be appropriate as part of a treatment plan for spinal nerve impingement (also known as “pinched nerve”) due to the following problems: Degenerative Disc Diseases,  Spinal Stenosis,Generalized Hypomobility and Muscle Spasm. 

Mechanical spinal traction may help you if you are experiencing numbness, tingling, pain in your upper/lower extremities or neck/back pain and muscle spasms. If you are experiencing these symptoms consult your doctor for a physical therapy evaluation to see if spinal mechanical traction is right for you.


Paraffin Bath

paraffinThe application of heat to a specific area of the body through the use of paraffin. The part is quickly immersed in heated liquid wax and then withdrawn so that the wax solidifies to form an insulating layer. The procedure is repeated until the layer is 5 to 10 mm thick, and then the entire area is wrapped in an insulating material, such as a loose-fitting plastic bag or paper towels. The technique is effective for heating traumatized or inflamed areas, especially the hands, feet, and wrists, and is used primarily for patients with arthritis and rheumatism or any joint condition. The wax is removed following 15-20 minutes. Also called wax bath.


Hot Packs hot packs

Physical therapists wrap moist hot packs in several layers of towels and place them on the area that needs treatment. The heat
provided by the hot packs has several important benefits. It relaxes tight muscles causing tissues to relax. This decreases pain caused by muscle tension or spasms. It also causes vasodilatation of the blood vessels which increases circulation to the area. Patients with muscle strains, spasms, or arthritis often benefit from treatment with moist heat.


Cold Packs ice packs

 Cold packs are a frozen gel substance used by physical therapists to treat areas of pain and inflammation. The cold packs are covered with a thin cloth layer and applied directly to the area in need of treatment. The cold transferred to the patient’s skin, muscle, and tissue has several beneficial effects. The cold temperature causes vasoconstriction of the blood vessels in the area. This decreases the inflammation in the area. By decreasing inflammation, pain and swelling are decreased.divider_blue


cryocuff knee footThe Cryo-cuff device that uses both cold and compression simultaneously. The Cryo-Cuff is used both acutely following injury and postsurgically. It is made of a nylon sleeve that connects via a tube to a 1-gallon cooler/jug. Cold water flows into the sleeve from the cooler. As the cooler is raised, the pressure in the cuff is increased.
