Principles of Electrical Stimulation in
Therapy Verified and Updated Questions
and Answers (100% Correct Answers)
Selective Stimulation
Answer: Nerve response depends on diameter, depth, phase duration.
Large-Diameter Nerves
Answer: Depolarized before smaller diameter nerves.
Low Frequency
Answer: Stimulation below 15 Hz for muscle contractions.
High Frequency
Answer: Stimulation above 80 Hz for pain modulation.
Subsensory Level
Answer: No therapeutic benefits, no sensation felt.
Sensory Level
Answer: Depolarizes sensory nerves, slight muscle twitch occurs.
Motor Level
Answer: Visible muscle contraction without pain.
Noxious Level
Answer: Stimulates pain fibers with high intensity.
Muscle Fiber Level
Answer: Long phase duration directly depolarizes muscle fibers.
Pain Control
Answer: Masks pain, encourages release of opiates.
High-Pulse Frequency
Answer: Over 80 pps triggers enkephalins release.
Low-Pulse Frequency
Answer: Stimulates β-endorphin release for pain relief.

Motor-Level Stimulation
Answer: Pulse rise, phase duration, amplitude affect contraction.
Pulse Amplitude
Answer: Stronger contraction with increased current intensity.
Phase Duration
Answer: 200 to 400 microseconds recruits motor nerves.
Pulse Frequency
Answer: Less than 15 pps causes distinguishable contractions.
Neuromuscular Reeducation
Answer: Teaches muscle contraction, low-duty cycle used.
Strength Augmentation
Answer: Electrical contractions supplement voluntary contractions.
Prehabilitation
Answer: Strengthens muscle pre-surgery for better recovery.
Blood Flow
Answer: Muscle contractions increase local blood flow.
Wound Healing
Answer: Low-intensity current reduces healing time.
Control of Edema
Answer: Sensory-level stimulation inhibits edema formation.
Motor-Level Stimulation for Edema
Answer: Encourages venous return, reduces swelling.
Fracture Healing
Answer: Generators mimic electrical signals for bone growth.
Electrode Leads
Answer: Connect electrodes to the electrical generator.
Electrodes
Answer: Introduce current to body, forming closed circuit.
