EMG Biofeedback and Rehabilitation Techniques

This set of flashcards encapsulates the key concepts and practical applications of EMG biofeedback and electrotactile haptic feedback within rehabilitation, enhancing understanding in preparation for the exam.

What is EMG Biofeedback?

A technique that detects and measures muscle activity, providing feedback to help patients control it.

What is a key characteristic of non-invasive quantitative EMG?

It uses surface electrodes to assess muscle activity without penetrating the skin.

What are common methods for presenting results in EMG biofeedback?

Audio, visual, and sensory outputs.

What should be considered for patient follow-up in EMG biofeedback?

Post test review and scheduling of results.

What is one potential pitfall of non-invasive EMG?

ECG artifact due to volume conduction and muscle cross-talk.

Why is deep muscle analysis less effective in EMG biofeedback?

It is hard to ensure recording from the correct spot due to limited pickup radius.

What physiological changes can EMG biofeedback help with?

Controlling motor unit activity for recruitment or relaxation.

What are some contraindications for EMG biofeedback?

Skin irritations from gel or tape and metabolic confusion.

What are the goals of EMG biofeedback?

Increase amplitude, motor unit recruitment, and overall functional mobility.

How can you determine suitable patients for EMG biofeedback?

Assess if they have motor impairment and can utilize voluntary control.

What factors should be considered when developing EMG training strategies?

Learning theory, goal-setting, and task sequencing.

What is EMG biofeedback useful for in orthopedic populations?

Controlling pain and improving strength/function post-surgery.

What are some conditions EMG biofeedback can address?

Stroke, dysphagia, headaches, and urinary incontinence.

What does recent evidence suggest about biofeedback in neurologic populations?

Task-oriented biofeedback can improve gait velocity and stride length.

What benefits does combined therapy with biofeedback and FES provide?

Improved knee and ankle flexion during gait.

What is the significance of patient motivation in using biofeedback?

Motivation is crucial for effective use of feedback information.

What is electrotactile haptic feedback in rehabilitation?

A system enhancing sensory feedback for patients with sensory impairments.

How does electrotactile feedback aid prosthetic users?

By providing tactile sensations of pressure and vibration.

What are the primary actions of electrotactile feedback?

Stimulating nerve bundles to convey information through electrical stimulation.

What are some applications of electrotactile feedback in rehabilitation?

Improving hand function, dexterity, and strength in stroke rehabilitation.

What type of stimulation does electrotactile feedback use?

Varied electrical stimulation parameters such as duration, amplitude, and timing.

What is the role of wearables in electrotactile feedback?

To enhance rehabilitation experiences and provide sensory feedback during treatment.

Why is external feedback important in stroke rehabilitation?

It contributes to improved motor imagery learning and function restoration.

What does the Neuralign system facilitate?

Motion-activated electrical stimulation for shoulder muscle rehabilitation.

How does Chattanooga Tower estim units function in biofeedback?

It allows patients to volitionally activate stimulation based on EMG output.

What is one of the primary outcomes of using EMG biofeedback combined with electrical stimulation?

Better force perception and grip accuracy.

What aspect of therapy is emphasized in trends for biofeedback applications?

The development of personalized or adaptive therapies.

What is one challenge faced by biofeedback technologies?

Limited accessibility and increased costs.

What is the role of positive reinforcement in biofeedback training?

It is more effective than negative reinforcement for learning.

What is the importance of electrode placement in biofeedback?

Proper placement is crucial to maximize effectiveness in muscle response.

What is the significance of the feedback loop in EMG biofeedback?

It allows continuous monitoring and adjustment of muscle activity.

What populations can benefit from biofeedback techniques according to recent studies?

Orthopedic, neurologic, and chronic pain populations.

What does ‘haptic feedback’ refer to in the context of rehabilitation?

Feedback provided through touch sensations to enhance patient experience.

What are some common uses for electrotactile devices during therapy?

To enhance interaction with virtual environments and support motor control.

How does the feedback inform the neurological adaptation in rehabilitation?

It serves as a reliable source that the nervous system can adapt to facilitate learning.

What considerations should be made for electrode properties in haptic feedback?

They should prevent burns and shocks to ensure patient safety.

What is an essential aspect of setting EMG biofeedback goals?

Goals should be realistic and specific to the patient’s needs.
