A patient is experiencing acute post-op pain following right TKA. The PTA decides to use TENS for pain modulation. Which parameters would be most appropriate?
conventional, 100-150pps, pulse duration 50-80 ms, whenever there is pain
A patient reports unable to feel a 100 pps current during TENS treatment. The PTA would be most successful in stimulating the sensory fibers by:
Increasing frequency to 150 pps

There is very mild swelling in the knee, tenderness and warmth with palpation of gastrocs. What type of electrical stimulation and parameters would be most appropriate?
None - red flag, probable DVT
Your patient is a 56 year old woman who presents with foor drop s/p CVA. What types of electrical stimulation and parameters will be ideal for the patient?
NMES,
Biphasic, frequency 35-50pps, pulsed duration 200-350 μs,

ramp time at least 1sec, treatment time 10-30 minutes
A 69-year-old male presents with a 1-year history of chronic mechanical low back pain. He reports deep, diffuse aching pain (6/10) that persists throughout the day and is minimally responsive to short-term interventions such as heat used previously in the clinic. Patient has no sensation to light touch upon testing.
Which electrical stimulation modality is MOST appropriate? List all parameters (Time, frequency, Duration)
None - due to lack of sensation
