Which modality is typically used for pain modulation and muscle activation during rehab?

• A. Electrical stimulation
• B. Ultrasound
• C. Cryotherapy
• D. Massage therapy

Answer: (A)

Electrical stimulation is used because it can both modulate pain and actively activate muscles. At the sensory level (TENS), it helps reduce pain by altering how pain signals are perceived, which can make it easier to participate in therapy. At the motor level (NMES), it delivers impulses that cause muscle contractions, aiding strengthening, motor re-education, and preventing atrophy when voluntary activation is limited by pain or weakness. Other modalities like ultrasound, cryotherapy, or massage have important roles in healing, inflammation control, or tissue mobility, but they don’t provide direct, controlled muscle activation to the extent that electrical stimulation does.
