- Q 1/6Score 0A PTA is using electrical stimulation to increase a patient’s quadriceps strength, as suggested by the supervising physical therapist. Which of the following is the best protocol?29Electrodes placed over the vastus medialis obliquus and superior/lateral quadriceps – stimulation frequency set between 50-80 ppsElectrodes placed over the femoral nerve in the proximal quadriceps and the vastus medialis obliquus – stimulation on for 50 seconds and then off for 10 secondsElectrodes placed over the superior/lateral quadriceps and vastus medialis obliquus – stimulation on for 15 seconds and then off for 15 secondsElectrodes placed over the femoral nerve in the proximal quadriceps and the vastus medialis obliquus – stimulation frequency set between 50-80 pps

- Q1A PTA is using electrical stimulation to increase a patient’s quadriceps strength, as suggested by the supervising physical therapist. Which of the following is the best protocol?Electrodes placed over the vastus medialis obliquus and superior/lateral quadriceps – stimulation frequency set between 50-80 ppsElectrodes placed over the femoral nerve in the proximal quadriceps and the vastus medialis obliquus – stimulation on for 50 seconds and then off for 10 secondsElectrodes placed over the superior/lateral quadriceps and vastus medialis obliquus – stimulation on for 15 seconds and then off for 15 secondsElectrodes placed over the femoral nerve in the proximal quadriceps and the vastus medialis obliquus – stimulation frequency set between 50-80 pps60s
- Q2A patient is receiving electrical stimulation for muscle strengthening of the left quadriceps. One electrode from one lead wire, 4x4 inches in size, is placed on the anterior proximal portion of the left quadriceps. Each of two other electrodes from one lead wire are 2x2 inches in size. One of the electrodes is placed on the inferior medial side of the left quadriceps and one on the inferior lateral side of the left quadriceps. This is an example of what type of electrode configuration?QuadripolarTripolarMonopolarBipolar60s
- Q3When using electrical stimulation with a unit that plugs into the wall, the PTA must take many different safety precautions. Which of the following precautions would probably not increase the safety to the patient and therapist?Always adjust the intensity of stimulation during the off portion of the cycleBoth "never place near water pipes" and "adjust intensity only while off" are not likely to increase safetyNever use an extension cord when using a plug-in unitNever place the unit in close proximity to water pipes while treating the patient60s
- Q4A PTA uses functional electrical stimulation as part of a treatment regimen designed to improve quadriceps strength. Which on:off time ratio would result in the MOST rapid onset of muscle fatigue?1:43:15:11:660s
- Q5A patient staus post open knee meniscectomy is referred to physical therapy for neuromuscular electrical stimulation. The MOST beneficial frequency of treatment to promote strengthening is :Three times per weekOne time per weekTwo times per dayOnce every two weeks60s
- Q6A PTA is treating a 35-year-old man who has suffered a loss of motor control in the right lower extremity caused by peripheral neuropathy. The assistant applies biofeedback electrodes to the right quadriceps muscle in an effort to increase control and strength of this muscle group. The biofeedback can help achieve this goal in all of the following ways except :Assisting the patient in recruitment of more motor units in the right quadricepsProviding input on the patient’s ability and effort in contracting the right quadricepsProviding a measure of torque in the right quadricepsProviding visual input for the patient to know how hard he is contracting the right quadriceps60s
