BCIA Applied Psychophysiology in Pain Management 2 — Questions and Answers
Question 1: Electromyographic scanning is a technique used in biofeedback-assisted pain assessment to:
- Replace MRI for structural imaging of muscle tears
- Map surface EMG activity across multiple muscle sites to identify regional tension patterns (Correct answer)
- Measure nerve conduction velocity to diagnose neuropathy
- Calibrate EEG equipment before neurofeedback sessions
Correct answer: Map surface EMG activity across multiple muscle sites to identify regional tension patterns
EMG scanning uses surface electrodes to systematically measure muscle tension across multiple sites, creating a functional map of tension patterns that guides targeted biofeedback treatment for pain conditions.
Question 2: In biofeedback for temporomandibular disorder (TMD), the primary target muscle for EMG monitoring is:
- Sternocleidomastoid
- Masseter and/or temporalis muscles (Correct answer)
- Orbicularis oculi
- Frontalis
Correct answer: Masseter and/or temporalis muscles
TMD biofeedback targets the masseter and temporalis muscles — the primary jaw muscles involved in clenching and bruxism — to reduce excessive tension contributing to jaw pain and dysfunction.
Question 3: Which biofeedback modality is most appropriate for managing headaches triggered by sympathetic arousal and vascular mechanisms?
- EMG biofeedback of the masseter muscle
- Thermal biofeedback (hand warming) for vascular migraine prevention (Correct answer)
- GSR downtraining for electrodermal normalization
- SMR neurofeedback for seizure prevention
Correct answer: Thermal biofeedback (hand warming) for vascular migraine prevention
Thermal biofeedback (hand warming) targets the vascular mechanisms of migraine by promoting peripheral vasodilation and reducing cephalic vasomotor reactivity, supported by decades of clinical evidence.
Question 4: 'Learned muscle guarding' in chronic pain refers to:
- Voluntary strengthening exercises prescribed by physical therapists
- Conditioned involuntary muscle tension around a painful area that persists beyond initial injury healing (Correct answer)
- A technique for athletes to protect muscles during competition
- Acute protective reflexes only present during active tissue damage
Correct answer: Conditioned involuntary muscle tension around a painful area that persists beyond initial injury healing
Learned muscle guarding is a conditioned response where muscles around a previously injured area maintain elevated tension, often perpetuating pain after structural healing — a prime target for EMG biofeedback.
Question 5: In treating cancer-related pain with biofeedback, which approach has supportive evidence?
- Biofeedback is contraindicated in all cancer patients
- Relaxation-based biofeedback (EMG, thermal, HRV) for reducing cancer-related anxiety, tension, and procedural pain (Correct answer)
- Only neurofeedback is appropriate for oncology populations
- High-intensity EMG uptraining to improve muscle mass lost during treatment
Correct answer: Relaxation-based biofeedback (EMG, thermal, HRV) for reducing cancer-related anxiety, tension, and procedural pain
Relaxation-focused biofeedback modalities (EMG, thermal, HRV) have evidence supporting their use as adjuncts for managing cancer-related pain, anxiety, nausea, and procedural distress.
Question 6: A biofeedback practitioner treating a client with chronic neck pain notes elevated cervical paraspinal EMG at rest. The treatment goal should include:
- Maintaining elevated EMG to protect the cervical spine
- Training the client to recognize and voluntarily reduce cervical muscle tension through EMG feedback (Correct answer)
- Switching to alpha/theta neurofeedback without addressing the EMG finding
- Referring immediately without attempting biofeedback intervention
Correct answer: Training the client to recognize and voluntarily reduce cervical muscle tension through EMG feedback
Elevated resting cervical EMG is a direct treatment target — biofeedback teaches the client awareness and voluntary reduction of excessive cervical muscle tension that contributes to chronic neck pain.
