TEST BANK 2026 ACTUAL EXAM
PRACTICE QUESTIONS AND ANSWERS
(WITH COMPLETE HIGH-YIELD
EXPLANATIONS)
This premium, comprehensive question practice test bank is
specifically engineered to mirror the actual 2026 NBCE
Physiotherapy Board Exam blueprint. Each multiple-choice
question is immediately followed by the correct answer and
a high-yield, comprehensive rationale that covers critical
clinical parameters, absolute contraindications, and active
rehabilitation protocols. This resource serves as the
ultimate study guide to help chiropractic students maximize
their scores and pass their physical medicine board
examinations on the very first attempt.
Question 1
A 34-year-old female presents with acute low back pain following a lifting
injury 24 hours ago. There is visible muscle guarding and severe localized
pain. Which of the following electrical stimulation configurations is most
,appropriate for acute pain modulation using the Gate Control Theory?
A) Low-rate TENS (2–5 Hz) with motor-level intensity
B) High-rate TENS (100–150 Hz) with sensory-level intensity
C) Russian stimulation (2500 Hz) with a 50% duty cycle
D) High-Volt Pulsed Current (HVPC) at 5 Hz with motor-level intensity
Answer: B
Rationale: High-rate (conventional) TENS utilizes a high frequency (100–
150 Hz) and short pulse duration to selectively activate non-nociceptive A-
beta large-diameter fibers. This blocks pain signals at the spinal cord level
(gate control mechanism) without causing a muscle contraction, making it
ideal and comfortable for acute injuries.
Question 2
You are using a 3 MHz therapeutic ultrasound to treat a patient with
superficial de Quervain's tenosynovitis. During the treatment, the patient
complains of a sudden, sharp, aching pain over the radial styloid. What is
the most likely cause of this pain, and what is the immediate corrective
action?
A) Cavitation; decrease the frequency to 1 MHz
B) Microstreaming; increase the soundhead movement speed
C) Periosteal overheating; move the soundhead faster or lower the intensity
D) Impedance mismatch; apply more coupling gel
Answer: C
Rationale: A sharp, aching pain during ultrasound indicates periosteal
overheating caused by the accumulation of acoustic energy at the bone-
tissue interface. Immediate corrections include moving the transducer head
more rapidly, reducing the spatial average intensity, or switching to a pulsed
mode.
Question 3
A patient presents with subacute swelling following a grade II inversion
ankle sprain. You choose to use High-Volt Pulsed Current (HVPC) for
edema reduction. What is the correct polarity of the active electrode and
the physiological mechanism utilized?
,A) Positive polarity to attract negatively charged plasma proteins
B) Negative polarity to repel negatively charged plasma proteins
C) Positive polarity to cause vasoconstriction of local arterioles
D) Negative polarity to stimulate skeletal muscle pumping
Answer: B
Rationale: In the acute and subacute stages of inflammation, plasma
proteins leaking into the interstitium carry a negative charge. By placing a
negative active electrode (cathode) over the edematous area, the like
charges repel, pushing the proteins back into the lymphatic system to
reduce swelling.
Question 4
Which of the following modalities has the deepest tissue penetration depth
capability in the human body?
A) Shortwave Diathermy
B) Infrared Therapy
C) Ultraviolet Therapy
D) Cold Laser Therapy (Low-Level Laser)
Answer: A
Rationale: Shortwave Diathermy (SWD) is a deep-heating modality
capable of penetrating 3 to 5 cm or deeper into tissues with high water
content, such as muscle. Infrared and laser are superficial
thermal/photobiomodulation modalities (under 10 mm), and Ultraviolet is
highly superficial (under 2 mm).
Question 5
A 62-year-old male with a history of lumbar spinal stenosis presents with
bilateral calf pain exacerbated by prolonged walking. Which exercise
protocol is specifically indicated for this patient to minimize symptoms
during rehabilitation?
A) McKenzie Extension Exercises
B) Codman’s Pendulum Exercises
C) Williams Flexion Exercises
D) Buerger-Allen Exercises
, Answer: C
Rationale: Williams Flexion Exercises are designed to reduce lumbar
lordosis and open the intervertebral foramina and spinal canal. This directly
decompresses the neural structures in patients with spinal stenosis or
spondylolisthesis, relieving claudication symptoms.
Question 6
You are applying iontophoresis to treat a patient with calcific tendinitis of
the shoulder. You elect to use acetic acid to help dissolve the calcium
deposits. Which electrode must the acetic acid be placed under, and what
is its charge?
A) Anode; Positive
B) Anode; Negative
C) Cathode; Positive
D) Cathode; Negative
Answer: D
Rationale: Acetic acid carries a negative charge and is used to increase
the solubility of calcium deposits. Based on the principle that like charges
repel, a negatively charged drug must be placed under the negative
electrode (the cathode) to be driven into the target tissue.
Question 7
During traction therapy for a patient with a lumbar disc protrusion, what is
the minimum percentage of the patient's total body weight required to
achieve actual mechanical separation of the lumbar vertebral bodies?
A) 10%
B) 25%
%C) 50%
D) 75%
Answer: C
Rationale: To overcome the friction of the body on the treatment table and
the resistance of the lumbar musculature, a minimum traction force of
approximately 50% of the patient’s body weight is required to achieve
structural separation of the lumbar vertebrae.
