A 38-year-old female presents with chronic low back pain. She reports no history of opioid use, but has a high caffeine intake due to her job as a barista. She has tried physical therapy and over-the-counter pain medications with minimal relief. Her healthcare provider recommends TENS therapy. Which type of TENS would be most appropriate for this patient?

Back

Conventional TENS

Front

What is the frequency range for conventional TENS?

Back

50-150 pps

Front

What is the pulse duration range for low-frequency TENS?

Back

50-100 microseconds

Front

Which type of TENS should be utilized in the modulation mode to prevent the patient from getting too accustomed to the stimulation?

Back

Burst mode TENS

A 27-year-old male patient has a prescription for iontophoresis using dexamethasone for chronic Achilles tendonitis. Which of the following BEST describes the appropriate preparation of this intervention? A. Place the dexamethasone on the anode, C. Place the dexamethasone on the cathode, D. Place the dexamethasone on the anode and cathode, Place the dexamethasone on the skin

Back

Place the dexamethasone on the cathode

While managing a slow healing wound, a physical therapist considers the addition of electrical stimulation to expedite wound healing. Which of the following current types would BEST address the wound? Direct current, Alternating current, Monophasic pulsed current, Biphasic pulsed current

Back

Monophasic pulsed current

A patient presents to physical therapy with a prescription for iontophoresis. The prescribed dosage is 60 mA•min. The patient tolerates an intensity of 3 mA. For which duration should the therapist apply the iontophoresis?

Back

20 minutes

Front

A physical therapist chooses to perform electrical stimulation for pain control during therapeutic exercise to improve range of motion for a patient who has significant muscle guarding. Which of the following frequencies should the therapist utilize? 2 – 10 pps, 40 – 50 pps, 80 – 90 pps, 150 – 160 pps

Back

80 – 90 pps

Front

A physical therapist utilizes continuous ultrasound with a frequency of 1 MHz at an intensity of 2 W/cm² for 10 minutes. Which condition would BEST be treated with these parameters? Options: Tightness in the gastroc-soleus musculature, Tightness in Achilles tendon, Pain in the vastus lateralis muscle, Tightness in the medial collateral ligament of the knee

Back

Tightness in the gastroc-soleus musculature

Front

A physical therapist is delivering sensory level electrical stimulation to a patient. The therapist turns the amplitude up to a relatively high level, yet the patient does not perceive any stimulation. What should the therapist do?

Back

Turn off the machine. Check the connections between the leads and the machine. Check that the electrodes are connected well. Change the electrodes if they are lacking adhesive and old.
