What Is electrical Stimulation? Electrcial Stimulation is used in

physical therapy by placing lead wires and electrodes on the skin over target areas of the body. When the electrical stimualtion device is activited a signal is transmitted down the lead to the electrode where it causes depolarization of sensory nerves or motor units to help reduce pain or to increase musclar strength of atrophied muscles, along with many other uses.

Terms To know

Amplitude: Magntiude or the Intensity of the current.

Ramp up/Ramp down: Time it takes for the amplitude at the on/off time to to rise to peak amplitude and time from peak amplitude to back to zero

Pulse Frequency: The amount of energy being delivered to the body

Pulse amplitude: The amount of energy being released to the body

Uses In Physical Therapy

Pain management

Neuromuscular re-education

Hypertrophy of Muscle

Edema

Wound Care

Spasms

Iontophoresis

Biofeedback

Electrical Stimulation in Neuro Rehab Neuromuscular Re-education

Contraindications For It's Use Patients with implanted cardiac pacemakers, defibrillators, and brain

stimulators

Application on throracic region for patients with CHF, arrythmias, MI

Application over the carotid sinus

Application on cancerous tissue

Broken or irritated skin

Lack of sensation

Epilepsy

Application over protruding metal

Set up for shoulder subluxation

FES to Improve Ambulatory Function FES is a great option for patient who suffer from foot drop or plantar

flexor spasticity after a stroke

Placement is going to be on ther anterior tib --> refer to slide 9 to see placement

Placement on the quads is also an option for patients who stuggle to extend

the leg during swing phase of gait

FES should be used in conjunction with conventional stroke rehab
