Post-Surgical Recovery Technology

Retrain Your Muscles To Fire After Surgery

EMG biofeedback restores muscle activation and accelerates post-surgical recovery by reconnecting your brain to your body.

The Gap

You're Ready for More Than Maintenance

You’ve recovered from your injury. Your pain is gone. But now what? Without proper training, you risk losing rehab gains, developing compensatory patterns, or never discovering what your body is truly capable of.

“Generic gym programs don’t account for your injury history… and fear of re-injury keeps you from reaching peak performance.”

The Disconnection

Why Your Muscles Won't "Turn On"

The Hidden Barrier to Recovery: Arthrogenic Muscle Inhibition (AMI)

What Is Arthrogenic Muscle Inhibition (AMI)?

In simple terms: Your brain “shuts down” certain muscles to protect your joint after injury or surgery. Even after pain resolves, the inhibition remains—your brain hasn’t “turned the switch back on.” The result: You can’t fully activate the muscle, leading to weakness and slower recovery.

The Reality:

You’re not imagining it. You physically cannot contract the muscle due to neural inhibition.

Common Signs

Quadriceps feel weak or “won’t fire”
Can’t fully straighten knee
Operated leg fatigues quickly
Cannot perform a basic quad set
Visible muscle atrophy (smaller thigh)

“The frustrating part: Traditional strengthening exercises don’t work well when AMI is present—because you can’t effectively strengthen a muscle that won’t fully activate.”

The Solution

What Is Muscle Biofeedback (EMG)?

Real-Time Feedback to Retrain Your Muscles.

Muscle Biofeedback, also called EMG (electromyography) biofeedback, uses surface electrodes placed on your skin to measure the electrical activity of your muscles in real time.

How it works:

Small adhesive electrodes are placed on the inhibited muscle.
Electrodes detect muscle activity and send signals to a unit.
You see and hear real-time feedback of your effort.
You learn to activate the muscle by using the feedback as a guide.

Think of it like having a coach inside your muscle, telling you when you’re activating it correctly.

Prevention isn't about being careful.

It’s about training your body to move correctly automatically.

How It Helps Your Recovery

Restore Activation

Built on research-proven protocols that reduce injury risk by 50-70%

Accelerate Strength

Once a muscle activates properly, traditional strengthening becomes effective.

Prevent Compensations

Learn to use the correct muscles instead of developing poor patterns.

Speed Recovery

Built on research-proven protocols that reduce injury risk by 50-70%

Increase Confidence

Seeing your muscle fire gives you tangible proof of progress.

Reduce Re-Injury

Proper muscle function protects your joint long-term.

Common Conditions We Treat

Surgery

ACL reconstruction, total knee replacement, meniscus repair.

After Shoulder Surgery

Rotator cuff repair, total shoulder replacement, labral repair.

After Hip
Surgery

Total hip replacement, hip arthroscopy, labral repair.

Other
Applications

Chronic inhibition, persistent weakness, compensatory patterns.

Treatment Timeline

The Biofeedback Process

STEP 01

Assessment & Electrode Placement

We identify which muscles are inhibited and place small surface electrodes on your skin over the target muscle. This is painless.

STEP 02

Baseline Reading & Guided Training

We measure baseline activity, then you perform simple exercises while watching and hearing real-time feedback from the biofeedback unit.

STEP 03

Progressive Training

As activation improves, we progress to challenging exercises and eventually “wean” you off the feedback as your brain-muscle connection is restored.

Duration: 10-20 minutes, integrated into PT.
Frequency: 2-3x per week for 2-6 weeks.

The Science Behind Biofeedback

Why It Works

Muscle Biofeedback, also called EMG (electromyography) biofeedback, uses surface electrodes placed on your skin to measure the electrical activity of your muscles in real time.

Research Support:

Studies show EMG biofeedback significantly improves quadriceps activation after ACL reconstruction.
Patients using biofeedback regain strength faster than those doing traditional exercises alone.
Reduces the duration and severity of post-surgical muscle inhibition.

Holistic Approach

Integrating Biofeedback Into Your Rehab

Biofeedback is typically used in the early to mid-stages of post-surgical rehab (weeks 2-12) when muscle inhibition is most prominent. As your muscle activation improves, we transition to traditional strengthening, and most patients no longer need biofeedback once the brain-muscle connection is restored.

Biofeedback is combined with:

Manual therapy

Range of motion exercises

Blood Flow Restriction (BFR)

Progressive strengthening

Functional movement training

Prevention isn't about being careful.

It’s about training your body to move correctly automatically.

Frequently Asked Questions

Does biofeedback hurt?

Not at all. The electrodes simply rest on your skin and detect electrical signals. You won’t feel any stimulation.

How is this different from e-stim?

E-stim delivers current to cause contraction. Biofeedback monitors your muscle while YOU try to contract it voluntarily. It retrains your brain.

How long until I see results?

Many patients notice improvement within 1-2 weeks. Full restoration typically takes 4-6 weeks.

Does insurance cover biofeedback?

Biofeedback is integrated into your PT sessions and is typically covered under your PT benefits.
