THERAPEUTIC EXERCISE FINAL EXAM
2025 QUESTIONS AND ANSWERS
According to Ohm law, which of the following can increase current flow? - ANS Both A and D
What effect does a magnetic field have on tissue rehabilitation? - ANS Unknown effects
Assuming that the unmentioned variable remains constant, which of the following statements
is consistent with Ohm law? - ANS Increasing voltage will increase the current in a circuit.
Which of the following responses should occur when a current with high amplitude and a low
frequency is delivered to the body? - ANS Pulsed contraction
Which of the following statements accurately describes the difference between static and
current electricity? - ANS Static electricity describes the process of losing or gaining
electrons, whereas current electricity describes a stream of loose electrons.
Which of the following is NOT a contraindication of electrical simulation? - ANS Impaired
sensation.
Which of the following is not true for all electrical equipment? - ANS A positive terminal is
where current enters a generator from the body.
Which of the following effects of electrical muscle stimulation does NOT occur with "Russian
current?" - ANS Chemical effects.

, Which of the following combinations of electrical stimulation pulse rate and amplitude would
elicit the strongest muscle contraction? - ANS 40 pps, high amplitude
Which of the following is true for transcutaneous electrical nerve stimulation (TENS)? -
ANS Uses surface electrodes to deliver a pulsed electrical current through the skin to
stimulate nerves
Which of the following effects of electricity is used during iontophoresis? - ANS Chemical
During a TENS treatment, you apply 10 V to the patient and produce 0.002 A of current
stimulation, what is the resistance of the arm? - ANS 5000 Ω
Which of the following is a contraindication for iontophoresis? - ANS An allergy to the
medication to be delivered
Which of the following is a contraindication for the use of NMES? - ANS Patient with a
pacemaker, an injury over the heart or brain, and potential malignancies
A finite series of pulses flowing for a finite time period followed by no current flow is: - ANS a
burst.
Which of the following effects of electricity stimulates wound healing? - ANS Magnetic
Describe how a nerve's excitability (or the amount of electrical current needed to elicit an
action potential) is influenced by its size AND depth. - ANS A nerves excitability depends on
the amount of applied skin and action potentials in the target nerves. Size and depth depends
on how large the nerve is because it can be easily stimulated because of the large area.
Why can't NMES replace traditional weight training during rehabilitation? - ANS Because
NMES is a voluntary exercise that cannot recover muscle mass and it is a passive muscle
contraction.
