A 57 year old male patient is having difficulty with walking. The PT documents the left
knee extension strength to be 2/5 and decides to incorporate EMG biofeedback to
help increase motor recruitment. Which of the following protocol is the MOST
appropriate to increase motor recruitment for the knee extensors?
A. Begin with electrodes close together and biofeedback sensitivity is low
B. Begin with electrodes widely spaced and biofeedback sensitivity is low
C. Begin with electrodes widely spaced and biofeedback sensitivity is high
D. Begin with electrodes close together and biofeedback sensitivity is high

A patient presents to a clinic with Subacromial impingement syndrome. The PT
chooses to use ultrasound for deep heating of the rotator cuff muscles. Which set of
US parameters will be MOST effective at increasing the temperature of tissue 4.0
centimeters deep?
A. 1.0 MHz, 100% duty cycle with 5 cm sound head
B. 3.0 MHz, 100% duty cycle with 2 cm sound head
C. 1.0 MHz, 50% duty cycle with 2 cm sound head
D. 3.0 MHz, 50% duty cycle with 5 cm sound head
Give this one a try later!
A. 1.0 MHz, 100% duty cycle with 5 cm sound head
1 MHz gets deep enough, 5 cm sound head is common in larger joints
groups (2 cm for fingers etc/small joints), 100% duty cycle for heating
Pulsed US in Acute Condition = < 50% duty cycle
Pulse US in Chronic Condition = 100% duty cycle
A physical therapist is administering iontophoresis for the management of a sclerotic
scar in a patient with adhesive capsulitis. To administer this treatment, which ion and
polarity should be used?
